INTRODUCTION
GETTING STARTED
Thank you for purchasing a MAX Plus series power
amplier. Based on years of experience in designing
and manufacturing professional audio equipment,
we at Phonic designed this power amplier for those
who need an extremely powerful, reliable and sturdy
amplier with a small footprint. 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 Plus 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.
FEATURES
●
Up to 2200 Watts with only 2U footprint
●
Output: 300W for MAX 860 Plus, 450W for MAX
1500 Plus and 750W for MAX 2500 Plus, all at
4 ohms
●
High current toroidal transformer allowing high
power output with low noise and low distortion
●
Built in limiter with a button allowing user to
disable limiter’s function
●
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.
●
Before turning on the power, make sure the gain
controls are turned all the way down to prevent
other equipment from harm.
●
Check your cables regularly and label each end
clearly for easy identication.
●
Always turn the power off before connecting to
and disconnecting from the unit.
●
NEVER use solvents to clean the unit. Clean it
with a soft and damp or dry cloth.
INSTALLATION
MOUNTING THE UNIT
Designed to t into a standard 19-inch rack, this unit
only takes up 2 units of rack space. Secure this unit
with 4 rack-mount screws and cup washers. In gen-
eral, 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. Leave 1-rack space between power ampliers
and other devices to guarantee better cooling (see
Figure 1).

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. INPUT
With these balanced XLR input jacks, you can use any
XLR connector. These input jacks accept balanced and
unbalanced input. When sending unbalanced signal, the
3rd pin and the 1st pin of the XLR connector should be
connected (see Figure 2).

3. OUTPUT
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 (see Figure 3).

OPERATION

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.

9. PARALLEL / STEREO / BRIDGE MONO
OPERATION MODE
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.
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
continously.
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.
Center detented control allows 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.
