FRONT PANEL FEATURES

RACK HANDLES

The rack handles were chosen for comfort while carrying your Power 750 from place to place. They will also protect the front panel controls in the event the unit is dropped on its face. In some types of racks, the handles may need to be removed before installation. This is easily done by remov- ing the four screws holding them to the front panel.

VOLUME CONTROL

The Volume control affects the amount of signal driving the power amplifier. With the knob indicator in the full counter-clockwise ("MIN") position, turning the control clockwise will gradually increase the level the power amp sees and thus increase the overall volume. In most cases, we sug- gest you run the Power 750 with the Volume control set near maximum and control the level from your signal source (i.e. preamplifier, console, etc.). This will result in less knobs to worry about and insure repetitive gain structures. In any event, always keep an eye on the dot bar display to make sure the Power 750 is not being overdriven (+3 red LED continuously lighting) as this can result in damage to your speakers due to DC con- tent in a clipped waveform. Turning down the Volume control will correct this situation.

FOUR SEGMENT DOT BAR DISPLAY

The Dot Bar Display in your Power 750 can be thought of as a power amp "headroom" indicator whose markings are in dB increments. For exam- ple, running the Power 750 with the "0" yellow LED lighting on the musical peaks or transients gives the user a maximum of 3db of headroom available before the amplifier reaches clipping or maximum undistorted power as indicated by the following red LED marked +3. The user has reached maximum power from the Power 750 when the red LED is activated. Running the Power 750 with the +3 LED lighting continuously will expose your power components to more intense heat (shortening their life span) and can also eventually harm your loudspeaker components.

SPEAKER ON/OFF SWITCH

Moving the Speaker On/Off Switch to the "ON" position allows the signal from the amplifier to be heard through any speaker enclosure(s) connect- ed to the Power 750's output section. Moving the Speaker On/Off Switch down to the "OFF" position (labeled "Speaker") disables the Power 750's output section.

This feature allows the user to tune up without interfering with other band members, plug and unplug instruments without fear of a loud "pop," and various other applications.

NOTE: If you do not hear any sound when you plug in and your system is properly connected, check the position of this switch!

POWER ON/OFF SWITCH

Moving the Power Switch to the "ON" position will turn on the amplifier as indicated by the illumination of the LED directly above the switch.

REAR PANEL FEATURES

INPUT SECTION

UNBALANCED INPUTS

This is the main power amp input jack for most applications, and should connect to the "Unbalanced Output" on your preamp of choice (preferably an SWR Interstellar Overdrive or Grand Prix!). This input utilizes a standard 1/4" phone jack. Input impedance for the unbalanced input is 33K ohms. Maximum input level is 16 volts RMS.

BALANCED INPUT JACK

Some preamps are equipped with XLR output jacks as a superior option to regular 1/4" patching. An electronically Balanced (XLR) Input Jack is provided for premium signal integrity. Input impedance for the balanced input is 10K ohms. Maximum input level is 8 volts RMS.

Pin assignments for the Balanced Input is American Standard as follows:

Pin 1 = ground Pin 2 = + Pin 3 = -
