1. Power
The front panel power switch switches the AMP210/310 on or off. Red
LEDs behind the faceplate indicate power status. Whenever the amplifier’s
power switch is in the “ON” position the ring around the button is illuminated.
When the amp is “Active” (receiving signal) the side lenses become
illuminated and the signal LEDs show green. During “Standby” status (no
signal) the side lenses are not illuminated and the signal LEDs show orange.
2. Speaker Selector
Selects speaker set ( A or B )
3. Balance Trim
Fades speaker output between the Right and Left Channels
4. Volume Trim
Allows fine adjustment of amplifier volume.

6. Line 1 Input
A switching input that can be used if a second source is desired and will
take over when a signal is present and has at least a 5mV level. Whenever
there is no signal at this input, or a signal with less than 5mV level, the
amplifier switches back to the Line 2 or “primary” input.
7. Speaker Level Input Line Select
Switches the input of the speaker level input to Line 1 or Line 2.
8. Speaker Level Input
Can be used to connect a source with speaker level output instead of line
level outputs. Use the Speaker Level Input Line Select to route the source
to Line 1 or Line 2.
9. Line 2 Input/Output
The primary line level input and output for a single source connection.
10. Delay Time
Allows for a 3-15 second delay to be set and accommodate the source
connected to the Line 1 input.
11. Master Level Controls
Provides independent adjustment of Left and Right channel maximum
level.
12. Mode Select Switch
Switches the amplifier from Stereo mode to Bridged mode
13. 12V Trigger
Allows the AMP210/310 to be powered on by other electronics or to power
on other electronics via a 3.5mm mini phone plug cable.
14. Power Mode
Sets the power on option of the AMP210/310. Set it to Normal for manual
power on/off. Set to Auto-On for signal sensing. Set to Trigger if the 12V
Trigger input is used.
15. Right Channel Speaker Output
Right channel terminals for speaker outputs A and B.
16. Left Channel Speaker Output
Left channel terminals for speaker outputs A and B.
17. Mains Power Inlet & Fuse Holder
Accepts IEC type line cord. A fuse located in integrated holder provides
safety protection from fault conditions: replace fuse with one of same type
and rating only.
18. Mains Voltage Selector
Voltage selection switch is preset to 115V (USA). For use in areas which
require 230V contact your dealer. Fuse must be of type and rating marked
on amplifier for use at local mains voltage.
