INTRODUCTION
GETTING STARTED
Congratulations on your purchase of the MAX 3500
power amplier. Based on years of experience in
designing and manufacturing professional audio
equipment, we at Phonic designed this power am-
plier for those who need an extremely powerful,
reliable and sturdy amplier. Taking advantage of its
huge heat sink as well as its variable speed fan that
auto-adjusts fan speed depending on the temperature of the machine during operation, MAX power
amps are always able to perform. Its professional
quality output and its sturdy case design make this
unit great for various locations like churches, concert
tours, stages, disco, pubs, or any place that requires
amplier installation.
This unit is designed with great care and great attention to details, so please read this manual carefully.
Look after it and keep it in a safe place for future
reference.
1. Check the AC voltage before connecting the
power plug to the outlet. Make sure the AC power
supply shares the same voltage used in your
country (For example, while some countries use
100V, others use 120V, 230V, or 240V). Please
ensure your device is properly grounded.
2. Before turning on the power, make sure the gain
controls are turned all the way down to prevent
other equipment from harm.
3. Check your cables regularly and label each end
clearly for easy identication.
4. Always turn the power off before connecting to
and disconnecting from the unit.
5. NEVER use solvents to clean the unit. Clean it
with a soft and damp or dry cloth.

MOUNTING THE UNIT
Designed to t into a standard 19-inch rack, this
unit only takes up 3 units of rack space. Secure this
unit with 4 rack-mount screws and cup washers. In
general, power ampliers usually are heavier than
any other audio equipment, so when installing this
unit onto a rack, begin placing it from the bottom of
the rack. We advise leaving one rack-space between
power ampliers and other devices to guarantee bet-
ter cooling (see gure 1).

Binding Post Output
1. Heat Ventilation
This unit comes with variable speed fan that auto-adjusts
fan speed depending on the temperature of the machine
during operation. Be sure not to obstruct the heat vents in
any way. This will ensure the amplier is always properly
ventilated.
CONNECTIONS
2. XLR Input Connectors
Connect your source to the XLR jacks, which are commonly used for both mobile and installation set-ups. They
provide a good combination of ease of connection and
resistance to corrosion. These inputs should be wired as
shown in gure 2.

3. Output Connectors
Binding posts and speakon connectors make up the unit’s
output section. Loudspeakers can easily be connected
using banana plugs, spade lugs, bare wires or speakon
connector. More people prefer using speakon than other
connectors because it’s the least likely to be disconnected
by accident or cause electrical shock. Because speakon
comes with four wires inside, you can connect to two speak-
ers with only one channel output. Be careful when making
connections since improper connecting could cause the
unit to short circuit. The minimum impedance setting for
STEREO and PARALLEL operation is 4 ohm, while 8 ohm
is the minimum for BRIDGE MONO operation. See gure
3 for wiring information.

OPERATION
Front Panel
4. Power Switch
This switch turns the power of the unit on. Remember to
turn the gain controls down before turning power on or off,
even though it comes with a POWER ON / OFF MUTING
feature. In general, the power amplier should be the last
piece of audio equipment to be powered on, and the rst
to be powered off, in a PA system.
5. Power LED
This blue LED comes on when power is on.
6. Peak LED
When the input signal level becomes too high, causing
input signal to loss denition and to distort, this red LED
comes on. When this happens, turn the gain control down
until the PEAK LED no longer comes on or remains on
continuously.
7. Signal LED
Every channel comes with a signal LED, allowing user to
monitor signal level. A minimum level of -30dBu is required
for the LED to go on.

8. Gain Controls
These two rotary knobs control the signal level of the input. These center detented controls allow precise volume
setting. Slowly turn the knob clockwise to increase input
level, but make sure that PEAK LED does not remain on
or blink constantly.
Rear Panel
9. Grounding/Floating Switch
This switch allows the circuit and chassis grounds to be
separated in case of a ground conict. In normal use the
switch should be in the Ground On position. Lifting the
ground (Floating position) may resolve the ground conict,
but means that circuit grounding will depend on other con-
nected components. Deciencies in other components’
grounding will affect the sound and a serious electric fault
with the amplier could damage other components in the
system.
10. Parallel / Stereo / Bridge Mono Operation
Mode Switch
There are three operation modes for different use. To
avoid damaging your PA system, remember to turn the
power off before switching from one mode to the other.

PARALLEL
When set to PARALLEL mode, the input signal of channel 2 parallels the input signal of Channel 1, so only one input jack
is needed for the signal source. Even though the input signal of both channels parallels each other, the output level of each
channel is determined by its own independent gain controls. So the two channels sharing the same signal do not share the
same output level (see gure 4).
Figure 4 Parallel Mode
STEREO
STEREO mode is the most frequently used mode among the three. Each channel is independent of the other, carrying its
own input signal, with its own gain control. Stereo mode comes in left and right channels (see gure 5).
A) When one channel is assigned for left channel, make sure the other channel is assigned for the right.
B) User can use the unit for mono output, with one as main and the other as monitor.
C) This power amplier can also be used for bi-amplication. One channel is used for driving low frequencies while the
other for driving high frequencies.
