FRONT PANEL CONTROLS

1. Power Switch

Switches the APA102 on or off. A red LED indicates connection to AC power

while in standby mode. Turns green indicating audio signal is present.

2. Speaker Selector

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

REAR PANEL CONTROLS

5. Bass and Treble Controls

These controls can adjust bass and treble frequencies +/- 12dB at 100Hz

and 10kHz.

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. 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.

8. 12V Trigger In/Out

Allows the APA102 to be powered on by other electronics or to power on

other electronics via a 3.5mm mini phone plug cable.

9. 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, plug

RCA cables in to Right and Left RCA at MAIN input. Set the MODE

switch to BRIDGED and follow the instructions for bridged speaker

connection in the SPEAKER TERMINALS section of this manual.

NOTE:The APA102 supplies 160W in bridged mode, Please verify that your

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

10. 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 rpower switch must be in the ON position

(pushed in) for the AUTO ON feature to operate.

11. Speaker Zone a Output

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

bridged or 4 ohm stereo.

3. Balance

Fades speaker output between the Right and Left Channels

4. Volume

Adjusts ampliﬁer volume.

12. 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.

80' or Less – 16 Gauge 2-Cond. CL3/FT4 Rated

80' to 150' – 14 Gauge 2-Cond. CL3/FT4 Rated

150' or more – 12 Gauge 2-Cond. CL3/FT4 rated

13. Unswitched Outlet 120VAC

The APA102 has an un-switched electrical outlet on the rear panel for use

with low power auxiliary devices; up to 400 watts. This outlet provides

power as long as the APA102 is plugged in, even if the unit is not turned on.

14. Power Cord

This ampliﬁer is conﬁgured for operation at 115V (North America). A fuse

located internally protection from fault conditions. Refer to qualified

service personel should this need to be replaced.
