ATI Audio ADA 412-XLR Quad 1x3 Low Noise Analog Distribution Amplifier - XLR Connectors

ATI Audio ADA 412-XLR Quad 1x3 Low Noise Analog Distribution Amplifier - XLR Connectors

The ADA412-XLR designed by ATI is an amplifier capable of routing audio to four 1x3 distribution amplifier channels, all via balanced XLR inputs and outputs. A master gain adjustment control for each channel is offered in the unit, while individual trimmers are on hand for each output to accommodate gears of various sensitivities over its 20 dB range. Use it for distributing audio in nightclubs, offices and more.

With the ATI ADA412-XLR, you are sure to get a low-noise and strong-signal operation as the unit is RF protected for removing noise from radio interference. It is also designed for giving you pure signal even when you are using lossy cable splitters over long cable runs.

• Easy Installation for Office Use: The ADA is designed for rack mounting on standard racks. Each unit dissipates approximately 10W and is designed for use in an office environment.
• Powerful Circuitry with Accurate Controls: An LF347N quad bi-FET op-amp forms the three variable gain output adjustment stages. These variable gain stages use a circuit arrangement that allows ATI to provide a smooth, logarithmic gain control for each output using a linear cermet potentiometer. Since the ADA412 actually reduces the stage gain for low outputs rather than taking the more conventional approach of reducing the input level to a fixed gain amplifier, you can use the ADA at low output levels with very little noise penalty.
• Protected against RFI: ATI has taken measures to keep RFI out of the unit, including split and bypassed input networks, beaded, bypassed, and isolated power inputs, nonconcentric wound, semi-toroidal power transformers, double ground plane PC boards, and a quality enclosure to keep rain and snow off the circuit boards.
