Connecting to the wrong voltage is dangerous and may damage the amplifier. Always be sure the source voltage for your areas matches the required voltage for your amplifier. Gain Controls -The gain controls are located on the front panel and are calibrated in 2dB of attenuation from full gain. It is best to adjust the amplifier so no “hissing” is heard from speakers with no music being played, this will ensure the lowest possible distortion during normal operation. AMPLIFIER FEATURES: THRU -Thru will allow the user to daisy-chain one amplifiers signal input into another amplifier. Plug the signal source outputs into the first amplifier’s input, patch from the amplifier’s THRU jacks to the next amplifier’s input, and so on, daisy-chaining as many amplifiers as there is no excessive level loss. Is not affected by crossover setting. GROUND LIFT SWITCH -Applying or lifting the ground switch will change the level for background noise and hum, if the noise level remains the same in either position, it is better to keep the ground lift switch in the ground position. This will eliminate 60Hz cycle hum that is sometimes induced when mounting several units in the same rack. OPERATING VOLTAGE (AC MAINS) - The serial number label indicates the correct AC main voltage. Connecting to the wrong voltage is dangerous and may damage the amplifier. GAIN CONTROLS -The gain controls are located on the front panel and are calibrated in 2dB of attenuation from full gain. It is best to adjust the amplifier so no “hissing” is heard from speakers with no music being played, this will ensure the lowest possible distortion during normal operation. LED INDICATORS - Each channel has five LEDS. Two LEDs indicate signal level activity; one green LED and one yellow LED. One red LED indicates signal clipping. One red LED indicates protections mode for shorts/ overload. One green LED indicates an active signal. Both channels will also share the center blue LED that indicate the amplifier operating mode. ©American Audio® --V-01 Series™ Power Amplifier User Manual Page 16 ©American Audio® - - V-01 Series™ Power Amplifier User Manual Page 17 Use the two red terminal from the banana jacks to Use either the Speakon or the banana jacks power a subwoofer speaker in mono-bridge mode.
