6. Bass and Treble Controls
These controls can adjust bass and treble frequencies +/- 12dB at 100Hz
and 10kHz.

7. 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.

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. 12V Trigger

Allows the AMP100VS to be powered on by other electronics or to power
on other electronics via a 3.5mm mini phone plug cable.

10.

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 AMP100VS supplies 150W in bridged mode, Please verify that your
speakers are capable of handling such power to avoid possible damage!

11.

AUTO ON Select Switch

Power can be turned on and off manually via the switch on the front panel
or automatically by signal sensing. Set it to NORMAL for manual power on/off.
Set to AUTO for signal sensing; the amp will turn on when audio signal is
detected at the inputs. NOTE: The front panel power switch must be in the
ON position (pushed in) for the AUTO ON feature to operate.

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.

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.

NOTE: To prevent sonic degradation in your speaker installation, total speaker
wire resistance should be kept below 0.5 ohms. This table lists recommended
speaker wire gauge versus wire run length.

14. Unswitched A/C Terminal
Provides A/C power for additional components. Use only for a single low
power device such as a tuner, CD, DVD, turntable or other non-amplified
electronics. Do not connect another amplifier or receiver. Ensure 400W
max power connumption for any device plugged in here.

SETUP FOR MULTIPLE SOURCE

In the multiple source set up, a distributed audio system is connected to the
AMP100VS as a local zone amplifier via the MAIN inputs. Normally the distributed
audio system will be the audio source for the AMP100VS. The distributed audio is
then passed on to be used by additional zones or sub zones in the distributed
system via the MAIN outputs.

(From Local Source Line Out)

The audio output of a local source, such as an MP3 Player, CD, television,
computer, etc., is connected to the AMP100VS via the INTERRUPTING inputs, and
whenever the local source is active its signal will take priority over the
distributed audio signal present at MAIN input . However, the distributed audio signal
will still be present at the MAIN input. In this circumstance the audio output of the
local source will be heard via the AMP100VS. Once the local source is turned
off or muted, the AMP100VS will automatically switch back to the distributed audio
system as an audio source, assuming the local source remains inactive. There
is a delay of up to 6 seconds when switching from INTERRUPTING input back
to MAIN inputs.
