6.
Bass and Treble Controls
These controls can adjust bass and treble frequencies +/- 12dB at 1OOHz
and 10kHz .
7. lnterupting 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 10mV level. When there is no signal, or a
signal with less than 10mV level, the
amp switches back to MAIN IN after a
a briefdelay (delay can be set by the "Delay Time" control).
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. Speaker LevelInput/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.
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 AD3002 supplies 600W in bridged mode , Please verify thatyour
speakers are capable of handling such power to avoid possible damage!
11 . Delay Time
Allows for a 3-15 second delay to be set when switching from the Interrupting
and Main Input.
12. Optical
Input
This input uses a fiber optic cable to transmit a digital signal to the amplifier.
Use of this input is recommended for advanced users who are familiar with
the audio source's
OSD system . When using the Optical input, make sure
the source unit the cable is plugged into is in Digital PCM (2 Channel) Mode.
Please refer to your source's operating manual when using this input.
NOTE: Optical Input will not decode 5.1 or 7.1 signals; only Digital PCM signals.

Speaker output terminals for output B. Minimum impedance: 8 ohm bridged
or 4 ohm stereo.
15. SpeakerA
Output
Speaker output terminals for output A. Minimum impedance: 8 ohm bridged
or 4 ohm stereo.
SPEAKER TERMINALS -STEREO MODE
For stereo output
conned 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 nextto the bridging mark, and
the speaker's negative (black) terminal to the amplifier's unmarked positive
(red) terminal.
NOTE: Only one output (A
or B) can be bridged. Do notattempt 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 tenminal
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.
16. Mains PowerInlet & Fuse Holder
Accepts IEC type line cord. A fuse located in the integrated holder provides
safety protection from fault conditions: replace fuse with
one of same type
and rating only.

SETUP FOR MULTIPLE SOURCE
In
the multiple source set up, a distributed audio system is connected to the
AD3002 as a local amplifiervia the MAIN inputs. Normallythe distributed
audio system will be the audio source for the AD3002. The distributed audio
is
then passed on to
be
used by additional amplifiers in the distributed system
via the MAIN outputs.
Connect Local Source
Line Out here (such
as
.mp3 player) Line Out to
Additional Amplifiers
Use these Inputs to connect
Pre-amp or Receiver Line Out
The
audio
output
of
a local source, such as
an
MP3
Player, CD, television,
computer, etc., is connected to the AD3002 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
AD3002.
Once
the
local
source
is turned
off
or
muted,
the
AD3002 will automatically switch back to the distributed audio
system as an audio source, assuming the local source remains inactive. There
is a delay ranging from 3 to
15
seconds (based
on
the "Delay Time" setting) when
switching from INTERRUPTING input back to MAIN inputs.
A Note On Distortion
Digital amplifiers distort differently than conventional Class
NB
amplifiers.
If
you
heara clicking or popping sound at high volume levels, this is an indication the
AD3002 is distorting. Pushing the amplifier harderthan the distortion level may
triggerthe amplifier's protection circuitry which will turn the output
of
the amplifier
off
and engage the red protection LED.
If
this occurs, you can reset it by cycling
the power button.
The
AD3002 is designed to exceed all power levels stated
in
this manual by a good margin, so ifthe amplifer is distorting orit's output protection
is engaging, reduce the volume using the rear panel Level Controls.
Impedance Matching Volume Controls
When using Impedance Matching Volume Controls (such as the AudioSource
AE1
OOVC),
please ensure the switch setting is correct for the number
of
Volume
Controls used. Mis-matching the control can lead to amplifier shutdown. In add-
ition,
if
the amplifier shuts down momentarily at high volume levels, the maximum
wattage is being exceeded by the amplifier and the volume should be reduced.
If
clicking
or
popping sounds come from the speakers
at
high volume, reduce the
volume as this is
an
indication that the amplifier is clipping and at maximum volume.
Using the Rear Level/Front Volume Trim
The AD3002 has rear mounted master level controls and a front panel volume trim
control. This setup is intended to allow the user to set a "do not exceed" volume
level. To
do
so,
start with the rear panel level controls at minimum.Turn the front
panel Volume Trim control to maximum and play music from the chosen source.
Slowly turn up the rear panel level controls to the maximum volume needed. Next,
turn the front panel volume trim control down (counter-clockwise) by 6
to
10
"Clicks" (each click is a 1dB adjustment). This will allow the front panel volume trim
to adjust the output volume by a range
of
18dB.
