INTRODUCTION
Congratulations on your purchase of the MAX 3500 power amplifier. Based on years of experience in designing and manufacturing professional audio equipment, we at Phonic designed this power amplifier for those who need an extremely powerful, reliable and sturdy amplifier. 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 amplifier 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.

GETTING STARTED
1.Check the AC voltage before connecting the power plug to the outlet. Make sure theAC 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 identification.
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.
INSTALLATION
MOUNTING THE UNIT
Designed to fit 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 amplifiers usually are heavier than any other audio equipment, so when installing this unit onto a rack, begin placing it from the bottom of therack.Weadviseleavingonerack-spacebetween power amplifiers 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 amplifier 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 figure 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 comeswithfourwiresinside,youcanconnecttotwospeakers 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 figure
3 for wiring information.

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 figure 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 figure 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 amplifier can also be used for bi-amplification. One channel is used for driving low frequencies while the other for driving high frequencies.
