User Manual

AMP310VS
1. Power Switch
Switches the AMP310VS on or off.
2. Clip LEDs
Blinks red during signal clipping. Shows solid red during protect mode.
Check speaker wires for shorts or extreme low impedance (< 4 ohms).
4. Balance
Fades speaker output between the Right and Left Channels
5. Volume
Trims amplifier volume from -12dB to +6dB referenced to the rear panel Level
controls.

6. 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.
7. 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.
8. Main Input/Output
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.
9. Delay Time
Allows for a 3-15 second delay to be set and accommodate
the source connected to the Interrupting Input.
10. Bass and Treble Controls
These controls can adjust bass and treble frequencies +/- 12dB at 100Hz
and 10kHz.
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.
STEREO MODE
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.
BRIDGED MODE
When set to “Bridged” mode, the amplifier is a single channel mono amplifier.
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.
NOTE: The AMP310VS supplies 450W in bridged mode, Please verify that your speakers
are capable of handling such power to avoid possible damage!
Figure 2. Rear Panel
13. 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.
15. Speaker Zone A Output
Speaker output terminals for zone A. Minimum impedance: 8 ohm bridged
or 4 ohm stereo.
16. Speaker Zone B Output
Speaker output terminals for zone B. Minimum impedance: 8 ohm bridged
or 4 ohm stereo.
SPEAKER TERMINALS - STEREO MODE
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.
SPEAKER TERMINALS - BRIDGED MODE
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 (red) terminal.
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.
