CONNECTIONS

1.Before plugging in the power cord, make sure that the VOLTAGE SELECTOR (30) switch is set to the correct voltage.

)NOTE: This product is double insulated and is not intended to be grounded.

2.Make sure that the POWER (1) switch is in the off position. The POWER LED (2) will be off.

3.The PS-650i is supplied with four (4) sets of output jacks.

•The 1/4" BALANCED OUTPUT (29) jacks are used to connect to your main amplifier using standard balanced cables. We recommend using balanced amp outputs if the cables to your amp are 10 feet or more.

•The MAIN OUTPUT (38) (RCA type) jacks are unbalanced and used to connect to your main amplifier.

•The REC OUTPUT (40) (RCA type) jacks can be used to connect the mixer to the record input of your recorder enabling you to record your mix.

•The BOOTH OUTPUT (39) (RCA type) jacks allow you to hook up an

additional amplifier.

5.On the rear panel are 2 stereo PHONO (32,34) inputs, 2 stereo LINE (31,33) inputs and 1 stereo PHONO/LINE (36) input. The PHONO/ LINE (35) switch enables you to set the (36) input to Phono or Line. The phono inputs will accept only turntables with a magnetic cartridge. A GROUND (37) screw to ground your turntables is located on the rear panel. The stereo line inputs will accept any line level input such as a CD player, a cassette player, etc.

6.Headphones can be plugged into the front panel mounted HEADPHONE (4) jack.

THE GROUND LIFT SWITCH

Depending on your system configuration, applying the ground sometimes creates a quieter signal path. Sometimes “lifting” the ground eliminates loops and hum to create a quieter signal path.

1.Listen to the system with the unit ON, without music, and with the ground “applied”. GROUND LIFT SWITCH (41) should be to the left.

2.Turn power OFF before moving the GROUND LIFT SWITCH.

3.Now, “lift” the ground by moving the GROUND LIFT SWITCH to the right. Turn the power back ON and listen to determine which position provides a signal free of background noise and hum.

Note: Keep GROUND LIFT in the ground “applied” or left position if noise level remains the same in either position.

CAUTION: DO NOT TERMINATE THE AC GROUND ON THE POWER CABLE. TERMINATION OF THE AC GROUND CAN BE HAZARDOUS.

OPERATION

1.POWER ON: Once you have made all the equipment connections to your mixer, press the POWER SWITCH (1). The power will turn on and the POWER LED (2) will glow RED.

2.CHANNEL 1: The GAIN (6), HIGH (7), MID (8), and LOW (9) controls allow you to fully adjust the selected source. Switch (10) allows you to select either the mic or the PHONO/LINE (36) input. The CHANNEL SLIDE (13) controls the output level of this channel.

3.MAIN CHANNEL SECTION: To assign an input source to a channel, first set the PHONO/LINE (11,12) switches to their appropriate positions. To make the proper adjustments to your music, set the GAIN (6), HIGH (7), MID (8) and LOW (9) controls, and position the CHANNEL SLIDE (14,15).

PLEASE NOTE: There is Low, Mid and High equalization for each channel with an extremely wide range of adjustment.

SUGGESTION: You can use the Cut Features on each channel to remove Low, Mid and/or High range to create special effects.
