AmpTraXX gives you sixteen channels of amplification and EQ in just two units of rack space. In many systems it eliminates the need for expensive EQ or DSP racks. It's a complete audio processing and distribution system in a single box.

Each AmpTraXX channel has independent filter configuration (lowpass, highpass, bandpass, notch or none) and parameter adjustments including gain and cutoff frequency. This can solve many installation problems without the addition of expensive signal processing.

For example, you can roll-off low frequencies when using parabolic speakers, or boost base response for smaller, inefficient drivers. AmpTraXX wrings the full potential from almost any type of speaker system.

Each channel provides 20 watts of power -- enough to deliver over 90dB into a 1600 square foot room with four ceiling mount speakers. We installed four ceiling-mounted speakers, each with a sensitivity of 90dB (@1W/1M) in a 40 foot by 40 foot room with a 10 foot ceiling. The total amplifier power required was actually only 8Watts, even allowing 6dB of headroom. Coverage was flat within 9dB throughout the space. And we had 15 channels left over!

By connecting multiple channels to the same input signal you could also create a sixteen channel speaker array, each with its own dynamically-adjustable active crossover network – that's 320 watts total RMS power.

AmpTraXX also makes life easier during installation. It helps solve speaker wiring mysteries with its internal 1KHz tone generator, which can be enabled on a channel-by-channel basis.

AmpTraXX is programmed using easy-to-understand, graphical software included with each unit. Setup is simple: select which filter you want on a particular channel, then move the sliders up and down to set gain, cutoff frequency, and filter Q. Settings are permanently stored in the unit's memory, and later can be uploaded if changes are needed.

AmpTraXX allows "on-the-fly" adjustments to channel volume and filter settings through the built-in RS232 port.

Manual controls located on the front panel allow for quick volume adjustments without the need for a computer or control system. With the flip of a DIP switch, these levels can be permanently stored in the unit and override previously stored values, or they can be disabled entirely to render the unit completely tamper-proof.

To aid in level settings, front-panel dual-LED indicators associated with each channel indicate signal present and "clipping" or overload condition. A blue power led is also provided.

For connecting AmpTraXX to balanced sources, a low-noise +4dBu balanced input option is available. Optional transformer modules are available for 70 or 100-volt speaker systems.

AmpTraXX applications include theme parks, museums, retail stores, restaurants, transportation systems, and multi-lingual environments. AmpTraXX is perfect for walking tours, multi-lingual audio and exhibit spaces, or any venue with lots of audio tracks and a central equipment space. It mates with Alcorn McBride's 8-TraXX audio player or any other line-level audio device to provide great density, attractive per channel pricing, and intelligent features for your most demanding applications.
