Technomad Loudspeakers Bring Clear Game Day Audio to High Schools and Colleges

AVX Northwest completes two Technomad athletic installations in Washington that brave the rainy elements outdoors and also provide crystal clear audio indoors

BOSTON, February 17, 2009 – Technomad LLC, a leader in weatherproof loudspeakers and audio systems since 1995, announces that AVX Northwest, an AV equipment dealer, consultant and installer based in Centralia, Washington, has completed two Technomad Turnkey PA school installations in the Pacific Northwest.The Technomad installations, at Saint Martin’s University of Lacey, Washington and Kalama High School of Kamala, Washington, provide substantial athletic sound system upgrades on the campuses indoors as well as outdoors.

“The reliability and durability of Technomad loudspeakers outdoors is renowned because of their weatherproof design, and the voice projection and musical quality is also very much appreciated in this industry,” said Mark Abbott, Founder of AVX Northwest. “That audio quality and reliability translates phenomenally indoors, especially in gymnasiums for live sports, concerts and other events. Indoors, we typically hang the loudspeakers on ceiling rafters and direct the loudspeakers so that there is an even pattern coverage across 360 degrees.The handoff from one loudspeaker to the next is virtually unnoticeable.”

Technomad Turnkey PA Systems typically include between two and four Technomad weatherproof loudspeakers, a 6RU signal processing rack featuring an amplifier, mixer and CD player, a dynamic microphone, and all associated cables and connectors to form a complete PA solution.Both campuses received Technomad Turnkey PA systems for various outdoor and indoor venues.Saint Martin’s University is sharing the signal processing rack between three venues, transporting it between a baseball field and fast-pitch softball field.

Abbott installed seven Technomad Paris 616 loudspeakers between the two fields: four for baseball, and three for fast-pitch softball.He installed the loudspeakers behind the backstops and along the first and third base lines to ensure clear coverage to all areas.Technomad’s new loudspeaker yokes were used to hang and support the loudspeakers, providing plenty of flexibility to shield the loudspeakers from line drives and position them for the best possible audio directivity.Abbott ran wiring to a lockable, vandal-proof box by the scorekeeping booth, where an operator can plug in and turn on the system for immediate operation.

Kalama High School purchased two fixed Turnkey PA systems for its multi-purpose outdoor stadium and gymnasium, where basketball and volleyball games and school concerts are held.According to Abbott, the multi-purpose outdoor stadium for football, soccer and track previously relied on a horn system that provided poor sound quality and fell into disrepair.Abbott installed four Nohos on the back rafters and wired the system so that the Turnkey PA rack is simply connected to pre-configured cable runs that descend through the press box ceiling.The result is a reliable, plug-and-play installation.

“The projection of the Technomads gives you more than any horn system could offer for voice, but the bigger difference is the bass response and music quality,” said Abbott.“Most of the announcers are male, and horns cannot precisely reproduce the male voice because of the lack of lower end.And bass reproduction is very essential for today’s music, which is especially important for football games and practices.”

According to Bruce Rader, school board president at Kalama High School, the Technomad system was part of a larger upgrade to the outdoor stadium that also involved a new turf and a paint job.“The old horn system sounded horrible; cheerleaders wanted to play music through it and it didn’t work.The four Nohos reproduce music very well and cover the entire stadium, from the home to visitor stands and across the field to each end zone,” he said.“Inside, we were using 20-year old loudspeakers, and Mark also recommended four Nohos.We thought that might be overkill, but the sound is loud and clear without coming across as overpowering.They sound incredible.”

Abbott added that the weatherproof aspect is highly important to withstand the consistent rain and dampness of the Pacific Northwest region, and the occasional weather-related curve ball.“This winter, we have had record amounts of snowfall,” he said.“To have a loudspeaker I don’t have to worry about out in the elements says it all.

“But the simplicity of this Turnkey PA System is that Technomad has done all the work,” added Abbott.“They wire the amplifier, mixer and take care of all the cabling in advance.Everything is self-contained and it is an excellent system for schools and colleges that are on a limited budget but want the versatility that comes with being on the go and supporting multiple events.”

Technomad Schedulon Product Test

We must thank the consumer electronics (PCs included) people who have developed cost-effective technologies that us pro audio folks can benefit from. Case in point is the advent of portable digital audio players (MP3 players). In the pro audio world, there is a number of manufactures that have developed and bring to market cost-effective digital or solid state audio recorders/players which have gained acceptance in many applications for field recording broadcast, sound reinforcement, and public address systems. It is not unusual now to hear these devices in use in many public spaces such as department stores, where a customer can press a call button on a pillar, which triggers a pre-produced announcement over the PA system alerting staff that “a customer requires service in the sports department,” or an announcement at the airport reminding us that the airport is a non- smoking environment.

There are many environments where a message has to be communicated to the masses either by immediate command through the push of a button, or triggered by a third-party control or by some internal scheduler. There is a number of fruitful choices from a number of manufacturers (TOA, Nel-Tech Labs, Raicom, TASCAM, Stop & Listen, etc.) that have developed products for common commercial audio applications. A recent addition to this arena of digital audio players is the Schedulon from Technomad (check out http://www.technomad. com). Yes, the folks who bring us military/ weatherproof-grade loudspeakers.

The Schedulon is a rackmount (1U) MP3 player/recorder with a built-in scheduler. With the use of a web browser or by navigating via a front panel knob and display, the Schedulon offers the ability to upload audio files, schedule playback of audio files, and automate playback of audio files.  The unit utilizes flash-RAM memory, which makes this unit more dependable than a PC-based solution. Although the unit has an onboard clock, audio files can also be triggered by an external clock server.

The Schedulon can record audio from its stereo line-in jacks   audio is encoded as high-quality (192 kbps) MP3 sound files and assigned to any desired knob location for playback. The better option is to upload the audio file using the browser application or to upload files to Schedulon’s USB memory drive from your computer.

The applications for the Schedulon and many similar units are numerous: repeat messaging at airports, department stores, malls, training facility scheduling (schools, airports, hospitals), corporate audio (no CDs to misplace), training, sports facilities (load team music or special effects for instant playback), automatic safety announcements, theme park audio, sound effects, pool-side music or DJ applications, and much more. Upon evaluation, it did not take much time to connect the unit and navigate through the browser.

Once connected and logged to the unit, you will discover six tabs (Status, Settings, Control, MP3 Upload, Knob Set, Scheduler) allowing you to view and enter values via drop-down selection. All but the Status tabs permit entering and adjustments to the unit. Without the use of a computer, you can navigate through the functions with the front knob and display, but this makes it taxing.

Different play modes can be assigned to each knob position: play forever/unit stopped by user (for sirens); play once, then stop automatically (for songs like the national anthem); and play while button held in (for sound effects). The fact that each knob position can store a different audio file AND play behavior is unique in the marketplace, I believe. The evaluation unit had 50 or so preloaded audio files, most of which, to no surprise, had military applications. One surprise that happened when I logged on was that the unit announced its IP address, which could inadvertently be announced over the PA system for all to hear. 
Generally, the unit worked to expectation, and can be recommended for applications as previously noted.

The unit we evaluated did not offer any contact closure or RS232 port for interconnectivity to other control systems. The audio outputs are unbalanced (not-so-pro audio), and the device’s “current time” is found at the Status tab; however, the current time should also be at the Scheduler tab for ease of reference during programming. Additionally, the unit data port is found in the front panel, something I would not expect if this unit is to be driven by external IP-based timer or clock. Projects or systems requiring additional features may not find this unit appropriate, but overall, the Schedulon is a good performer and is basic in operation and functionality.

Manufacturer’s Comment

The announcement of IP address can be turned off as an option. The unit can have sounds triggered by CGI commands via Ethernet/LAN, and  the unit can automatically synch itself to an external time server 
These are two different things. Both use the network. The time-server synch is critical if you need things to happen exactly on time, for years at a time. The Data Port (Ethernet port) can be located on the rear if requested at time of order. – Technomad LLP

Technomad in RoHS Compliance Move

Technomad Associates has altered its manufacturing process to ensure RoHS compliance for sales into the EU, writes David Davies. Based in Boston, Massachusetts, Technomad has been producing weatherproof loudspeakers and audio systems since 1995.

Now, to comply with EU regulations, Technomad has switched to RoHS-compliant driver and network components for deployment inside its loudspeakers, and eliminated the use of lead within the soldering process.

The new move on RoHS encompasses the entire Technomad product range, which includes IP56-rated weatherproof loudspeakers, the Schedulon automatic MP3 player and recording system, and the PowerChiton series of networkable weatherpoof powered amplifiers.

The RoHS announcement follows Technomad’s recent decision to convert to recycled plastic within its loudspeaker manufacturing process.

Rodger Von Kries, vice president of Technomad, told II: “Technomad is making a concerted effort to expand its presence in the EU marketplace. To that end, we’ve switched all of our manufacturing processes and components to be RoHS compatible. To offset the high import costs for smaller shipments, Technomad now stores a variety of our core products in a warehouse in the EU. This allows customers to purchase products at much lower costs than goods imported from the US and also decreases lead times.”

Technomad has also been working to enhance its appeal to the European market in other ways. “With an eye to EU sales, Technomad is also offering all of its electronic products – the Schedulon MP3 player/recorder (pictured), PowerChiton weatherproof outdoor amplifier modules and our Turnkey PA systems – all configured to run off 220V AC power. We feel that the weatherproof audio product market in the EU is under-served and that there are a lot of exciting opportunities for our product line in this region. We are actively working with a sale outreach firm in the EU to increase our dealer base and are currently looking for sales channel partners.”

Audio Review: Technomad Schedulon

Solid scheduling-enabled audio player and recorder that fits the simplicity bill.

By John McJunkin

Technomad, manufacturer of military-oriented audio equipment (particularly PA systems) has introduced its Schedulon scheduling-enabled audio player/recorder. This device is nearly identical to Technomad’s SuperConductor, which is the purely military version of the device. As a manufacturer of military-grade technology, Technomad is known to make its products figuratively bulletproof, and the Schedulon was developed with this notion in mind. It records to and plays back from RAM, so there are no moving hard-disk parts to cause problems. It’s distinguished from similar computer-based solutions by the fact that it is a standalone device, immune to viruses or operating system crashes or hang-ups. I’ve always been a great believer in over-engineering, which helps avoid embarrassment and, more importantly, the potential loss of clients that can be caused by equipment failures. The Schedulon very much appeals to my sensibilities in this regard.

The military recognizes that much of its equipment is destined to be operated by 18-year-olds who have little experience with technology, so simplicity is the key word. The Schedulon’s 1RU front and rear panels very clearly fit that bill. There are just five features on the front panel: From left to right, there’s an LCD display, a data-input knob, a removable thumb-drive access panel, an RJ-45 Ethernet port, and a large bat-handle power switch. The LCD displays 32 characters on two lines, and it is very reminiscent of the old-school Yamaha processors and synthesizers. The data-entry knob is of the large variety colloquially described as “chicken-head”; it spins continuously for data input and can also be depressed as a pushbutton switch. It doesn’t get much simpler than a single knob and a basic LCD display for control and feedback.

The rear panel is also simple. From left to right, you’ll find a fuse holder, the unit’s integrated AC power cord, a Neutrik 1/4in. TRS output jack, a second RJ-45 Ethernet port, and two stereo RCA pairs representing audio in and rec in. Again, the Schedulon sports a very straightforward, no-nonsense design, which is right in line with the requirements you’d expect from the military.

The Schedulon is essentially designed to do one thing: automatically play audio at prescheduled times or immediately under human control if desired. There are obviously numerous applications for such a device. In an educational setting, specifically a school, the Schedulon can be used to play tones or recorded speech intended to alert students that class begins in 10 minutes, again 5 minutes later, and then a final alert 1 minute prior to the start of each class hour. The minimum time resolution of the scheduling is 1 minute, so countdowns that update every minute are possible. Additionally, emergency messages can be delivered, alerting students of a fire or other dangers. For numerous applications, the ability to play hourly chimes to indicate the time is nice, particularly since a specific number of chime strokes can be played or even a pleasant voice can announce that it’s 10 o’clock, for example. Up to 100 scheduled playback events can be programmed into the system. In military settings, the device can be used to play Reveille in the morning, Taps at dusk, and other military-oriented sounds. As a matter of fact, the device ships from Technomad with quite a number of military sounds, including alarm sirens and bugle calls. Among other applications, the Schedulon would also be useful in subways, airports, hospitals, or other public buildings, even to provide BGM. For that matter, this system would be useful for any application in which you would otherwise use a flash-drive-based recording/playback system.

In addition to scheduled automatic playback, immediate manual playback is easily accomplished by the Schedulon, which would be useful in the case of an emergency or other situation that necessitates immediate, spontaneous playback of certain messages or alerts. The unit allows a maximum of 99 slots for audio. The maximum length of the audio is determined by the size of the removable flash thumb drive. The unit ships from the factory with a 1GB drive, but larger drives can be installed. The unit compresses audio into .mp3 files, with resolution ranging from 32kbps to 320kbps. Audio is recorded by the unit at 192kbps, which is difficult to distinguish from CD quality by most listeners without the benefit of an A-B comparison. At the nominally standard rate of 128kbps, hundreds of songs could be stored on a system with a 1GB thumb drive. Technomad says that a future version of the system will support the recording and playback of uncompressed 16-bit/44.1kHz WAV audio. The unit’s thumb drive is upgraded very easily by removing the front access panel, pulling the original drive out, and replacing it with the new one. Also, all system parameters, scheduling, and audio are stored on the thumb drive, so it can be transferred into another Schedulon unit — in effect cloning the original.

In line with the military aversion to computer viruses, complete control of all system parameters can be accomplished from the front panel, but computer control via Ethernet is indeed an option; this is the only way that externally recorded .mp3 files can be introduced to the Schedulon. It’s possible that the system would be loaded with all desired audio files and then installed with the intention of only front-panel control. On the other hand, since the system can be controlled remotely via IP, it is beneficial to maintain a network connection — particularly if you’re practicing good network security. Password protection prevents a malicious user from making changes, both from the front panel and via the network. Another major benefit to maintaining a network connection to the unit is that it can connect to a time server, keeping its internal clock precisely correct at all times. On a related note, the Schedulon has an optional backup battery available, which is again in line with the military notion of ongoing technology performance regardless of external circumstances. I discovered this battery feature when I jokingly flipped on the power switch before the unit was plugged in. Imagine my surprise when it fired up.

Among other advantages over similar audio-streaming-over-IP solutions is a network interruption that will not halt playback of critical audio from the Schedulon, since all the audio is stored internally. Additionally, IP bandwidth is not expended by audio streaming. I was prepared to announce that my only criticism of the unit was the somewhat unorthodox 1/4in. TRS audio output. I would normally expect Euro-style or barrier strips or a stereo pair of 1/4in. TRS jacks. As it transpires, however, I was shipped a beta unit. The production version will actually have stereo RCA pairs for input and output, which is a little more orthodox.

In spite of these minor inconveniences, this unit is very solid and would be a great choice for any application in which good-quality scheduled audio playback is necessary. I’d recommend taking a look at it.

Technomad Loudspeakers Provide Game Day Audio Coverage at Jamsil Baseball Stadium

Technomad  announced that C.I.C. Electronics, a Technomad dealer located in South Korea, installed a variety of Technomad weatherproof loudspeakers throughout Jamsil Baseball Stadium in Seoul.  C.I.C. Electronics, a global supplier of professional audio and public address systems selected Technomad loudspeakers for their outstanding audio quality and projection, weatherproof design, and durability.
Jamsil Baseball Stadium, built in 1982, seats 30,265 people and is home to both the Doosan Bears and LG Twins, both professional teams of the KBO Baseball League.  C.I.C. installed Technomad Berlin, Paris616 and Vernal-15 loudspeakers in various areas depending on the amount of power required for each specific location.  The Technomad Berlin, part of the company’s AS Series of loudspeakers, is the largest of the three models.  TheBerlin offers unparalleled projection, fidelity, and power to disperse intelligible voice and music throughout the stadium while maintaining an even pattern.
 
 
The Technomad Paris 616 and Vernal-15 models, part of the company’s MP Series of loudspeakers, offer more compact designs for all-environment installations, distributed systems, and sound reinforcement applications. Like the Berlin, both the Paris and Vernal offer unmatched fidelity as well as very broad dispersion to ensure that clear audio is hitting the most difficult-to-reach areas within the stadium.
 
Jamsil Baseball Stadium comprises part of the Jamsil Sports Complex along with nearby Seoul Olympic Stadium, and was host to baseball events during the 1988 Seoul Olympic Games.
