1. Power Switch

Switches

the

AMP310VS on or off.

Speaker Selector

Selects speaker zone A or B. For A + B zones push both buttons in.

Balance

Fades speaker output between the Right and Left Channels

Volume

Trims ampliﬁer volume from -12dB to +6dB referenced to the rear panel Level

controls.

FRONT PANEL CONTROLS

Interupting Line Input

This is the secondary input, use MAIN IN for your main input.

INTERRUPTING INPUT can be used if a second source is desired and

takes over when signal is present and has at least a 5mV level.

When there is no signal, or a signal with less than 5mV level, the amp

switches back to MAIN IN after a brief delay.

Speaker Zone A Output

Speaker output terminals for zone A. Minimum impedance: 8 ohm bridged

or 4 ohm stereo.

Speaker Zone B Output

Speaker output terminals for zone B. Minimum impedance: 8 ohm bridged

or 4 ohm stereo.

MAIN IN should be used as the “primary” or main input for the ampliﬁer.

Connect your receiver or main source to this input. Use MAIN OUT to pass

MAIN IN signal to another amplifier.

If you will be connecting one or two pair of speakers to the ampliﬁer, place

the switch in the “Stereo” position. NOTE: For playing 2 pairs of speakers

(A plus B), make sure each speaker has an impedance of 8 ohms or greater.

When set to “Bridged” mode, the ampliﬁer is a single channel mono amplifier.

NOTE: The AMP310VS supplies 450W in bridged mode, Please verify that your

speakers are capable of handling such power to avoid possible damage!

For stereo output connect the speaker’s positive (red) terminal to the ampliﬁer’s

positive (red) terminal, and the speaker’s negative (black) terminal to the

ampliﬁer’s negative (black) terminal for each Right and Left speaker.

Place the “MODE” switch in the “BRIDGED” position and use both red

terminals to connect to the speaker. Connect the speaker’s positive (red)

terminal to the ampliﬁer’s red (+) terminal noted next to the bridging mark, and

the speaker’s negative (black) terminal to the ampliﬁer’s unmarked positive

NOTE: Only one zone (A or B) can be bridged. Do not attempt to bridge both

A and B speaker terminals! This may result in a lower impedance than the

ampliﬁer is designed for and may damage your ampliﬁer. The minimum

impedance for the total load connected in bridged mode is 8 ohms.

STEREO MODE

BRIDGED MODE

BRIDGED MODE- MONO APPLICATION

For bridged mode, playing Right and Left together as mono output, use a

Y cable adapter to connect Right and Left RCA signal to the Right (Red) input

at MAIN IN. Set the MODE switch to BRIDGED and follow the instructions

for bridged speaker connection in the SPEAKER TERMINALS section of

this manual.

(red) terminal.

NOTE: Use Class 2 wiring for speaker connections.

To wire the output connector: 1. Strip the insulation off each speaker wire

to expose 3/8" (10 mm) of bare conductor. 2. Unscrew the output terminal

binding post several twists, insert each wire into the correct terminal.

3. Tighten binding post by twisting clock-wise until it is firmly clamping the

speaker wire.

Warning: While the amplifier does self-protect under most improper output

conditions, misconfiguration of loudspeaker mode and incorrect connection

of loudspeakers could damage connected loudspeakers and/or amplifier.

Please refer installation to a qualified installation professional, and always

check state and local electrical codes when installing.

Speaker Level Input/Speaker Level Input Line Select

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 either Main Input or Interrupt Input function.

Delay Time

Allows for a 3-15 second delay to be set and accommodate

the source connected to the Interrupting Input.

Master Level Controls

Provides independent adjustment of Left and Right channel

maximum level.

12V Trigger

Allows the AMP310VS 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 AMP310VS. Set it to Normal for manual power

on/off. Set to Auto-On for signal sensing power up. Set to Trigger if the 12V

Trigger input is used.
