is intended to alert the user to the presence of non-insulated “dangerous
voltage” within the product’s enclosure that may be of sufficient magni­tude to constitute a risk of electric shock.

Warning: to reduce the risk of electric shock, do not remove cover (or

back) as there are no user-serviceable parts inside. Refer servicing to
qualified personnel.

MAGNETIC FIELD: !!CAUTION!! Do not locate sensitive high-gain equipment such as preamplifiers or tape decks directly above or below the unit. Because
this amplifier has a high power density, it has a strong magnetic field, which can induce hum into unshielded devices that are located nearby. The field is
strongest just above and below the unit. If an equipment rack is used, we recommend locating the amplifier(s) in the bottom of the rack and the preamplifier

or other sensitive equipment at the top.

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.

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:

NOTE: Use Class 2 wiring for speaker connections.

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

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

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.

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.

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 wire resistance should be kept below 0.5 ohms. This table lists
recommended speaker wire gauge versus wire run length.

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.

APPLICATIONS

STEREO SETUP

In this configuration, the mode switch is set to “Stereo”. Connect the line out
jacks from a stereo pre-amplifier or source to the MAIN input jacks of your

APA102. Next connect your speakers to the terminals marked “Speaker A”
observing proper polarity. Select the “A” speakers using the front panel zone
selection buttons. Connect a second (optional) pair of speakers to the
terminals marked “Speaker B”. If you are connecting 4 speakers to the
APA102 they must be 8 ohm speakers only. Press A and B together to use
both zones.

SETUP FOR MULTIPLE SOURCE

In the multiple source set up, a distributed audio system is connected to the
APA102 as a local zone amplifier via the MAIN inputs. Normally the distribut­ed audio system will be the audio source for the APA102 . The distributed
audio is then passed on to be used by additional zones or sub zones in the
distributed system via the MAIN outputs.

Note: Main Out only duplicates what source is connected to the Main Input,
ideal for adding additional Amplifier or connect to Power Subwoofer.

NOTIC E TO BUY ER

This warranty gives you specific legal rights, and you may also have other rights which vary from state to state.

(From Local Source Line Out)

(From Pre-amp Line Out) (Out to Additional Zones)

The audio output of a local source, such as an MP3 Player, CD, television,
computer, etc., is connected to the APA102 via the INTERRUPTIN G 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 APA102. Once the local
source is turned off or muted, the APA102 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.
