PRODUCT DESCRIPTION The ADA208PH or ADA416PH provides two (208) or four (416) independent one-in by four-out circuit groups. A four-output feed is sufficient for many applications; however, if you need more outputs, you can parallel channels by bridging several inputs across the same line for 1X8, 2X8 or 1X16 operation.

The ADA has clipping indicators to warn you of overdriven and overloaded outputs. These indicators individually sense nonlinear operation of any output channel by measuring the error voltage at the feedback terminal of the HI side output amplifier. If any single output or any combinations of outputs are driven too high, they will light the clipping LED.
INSTALLATION The ADA Series Distribution Amplifier is designed for rack mounting on standard E.I.A. 1-3/4 inch centers. Each unit dissipates approximately 10 watts and is ventilated through slots in the rear panel. WIRING There are three wire grounded plugs. The power line ground could cause a loop with your studio ground.

CAUTION The Distribution Amplifier has active drivers for both HI and LO output terminals. DO NOT GROUND either HI or LO terminals. If you are driving a single-ended (unbalanced, one side grounded) high impedance or 600 ohm load, it should be connected between either HI to GND or LO to GND.
