FRONT PANEL CONTROLS
The front panel power switch switches the AMP210/310 on or off. Red LEDs behind the power button lens indicate power status. Whenever the amplifier’s power switch is in the “ON” position and the amplifier is in “Active” status the Signal/Clip LEDs are illuminated green. If the amplifier is “ON” but in “Standby” status the Signal/Clip LEDs will illuminate orange.
REAR PANEL CONTROLS
The AMP210/310 can be turned on and off independently via the power switch on the front panel, by signal sensing, or remotely by a triggered DC input. Switch 14 , located on the lower edge of the rear panel of the
AMP210 / AMP310
OWNER’S MANUAL
Begin Master Level control setup by adjusting the front panel “Volume Trim” to its fully clockwise position. Set the front panel “Balance Trim” to its center detent position. Now adjust both the Left and Right Channel Master Level controls to set a “Maximum” desired volume for the AMP210/310 in its application, as well as setting an appropriate “Balance” from left to right.
Now use the front panel Volume and Balance Trim controls to make fine adjustments to your setup in this application.

Figure 6. RCA Inputs
There are 2 pairs of RCA inputs on the back panel of the AMP210/310. These RCA inputs are labeled as “Line 1 IN” and “Line 2 IN”. They are also designated with an “R” or an “L” as Right channel or Left channel inputs respectively.
“Line 2 IN” should be used as the “primary” or normal input for various line level sources that may be available to the amplifier. “Line 1 IN” is a switching input that should be used when a second local source is connected, and will take over as the selected input whenever a signal with a minimum of 5mV of level is present. Whenever there is no signal at the “Line 1 IN” RCAs, or a signal with less than 5mV level, the input will revert back to the normal Line 2 input signal after preset delay.
An adjustable delay, of from 3 seconds to 15 seconds, can be set to accommodate the nature of the source connected to the “Line 1 IN” RCAs. As an example, if the “Line 1 IN” source was a CD Changer, the delay could be adjusted to prevent switching back to the “Line 2 IN” source while the changer moves from one disc to another.

8SPEAKER LEVEL INPUT
The AMP210/310 provides a pair of speaker level inputs for those applications where either of the sources has only speaker level output signal available. The switch 7 routes the speaker level signal to either the Line 1 or Line 2 input.
