Do not attempt to return this equipment to your dealer.

3.Do not expose this unit to direct sunlight or to a heat source such as a radiator or stove.

4.This unit should be cleaned only with a damp cloth. Avoid solvents or other cleaning detergents.

5.When moving this equipment, it should be placed in its original carton and packaging. This will reduce the risk of damage during transit.

6.DO NOT EXPOSE THIS UNIT TO RAIN OR MOISTURE.

7.DO NOT USE SPRAY CLEANERS OR LUBRICANTS ON CONTROLS OR SWITCHES.

Connections

1.Make sure that the POWER (22) switch is in the off position.

2.This unit comes supplied with a 15 volt AC adaptor. Plug the male pin of the adaptor into the rear panel POWER JACK (6). Then plug the adaptor into a proper power source.

3.To connect the mixer to your amplifier, use the MASTER (1) jacks on the rear panel.

4.The unit is equipped with one microphone input. The MIC JACK (15) is a 1/4" (6.35 mm) and is located on the front panel.

5.On the rear panel are 2 stereo PHONO/LINE (3, 4) inputs, 1 stereo PHONO (5) input and 1 stereo LINE (2) input. The PHONO/LINE SWITCHES (8, 9) enable you to set the (3, 4) inputs to Phono or Line. The PHONO (5) input will accept turntable inputs only. A GROUND (7) screw for you to ground your turntables is located on the rear panel. The stereo LINE (2) input will accept any line level input such as a CD player or a cassette player.

6.Headphones can be plugged into the front panel mounted HEADPHONE (26) jack.

Operation

4.CROSSFADER SECTION: The CROSSFADER (20) allows the mixing of one source into another. The left side of the CROSSFADER is CHANNEL 1 and the right side is CHANNEL 2. The CROSSFADER in your unit is removable and, should the need arise, can be easily replaced. Crossfader units are available in two varieties: part RF-45 (which is identical to the crossfader supplied with this mixer) has a 45 mm travel from side-to-side, while the PSF-45 is equipped with a special “curve” designed for scratch mixing.

To install a new crossfader:

1.Unscrew the outside FADER plate screws (B). Do not touch the INSIDE SCREWS (C).

2.Carefully lift the fader and unplug the CABLE (D).

3.Plug the new fader into the cable and place it back in the mixer.

4.Screw the fader to the mixer.

5.TALKOVER SECTION: The purpose of the talkover section is to allow the program playing to be muted so that the mic can be heard above the music. When the TALKOVER (11) button is pushed, the TALKOVER INDICATOR (10) will glow and the volume of all sources except MIC are reduced by -16 dB. MIC (17) controls the level of the talkover MIC.

6.CUE SECTION: By connecting a set of headphones (26), you can monitor either Channel 1 or Channel 2. Select Channel 1 by moving the CUE SWITCH (19) to the left. Move to the right for Channel 2. Use the CUE (18) control to adjust the headphone volume without affecting the overall mix.

7.DISPLAY: The DISPLAY (16) indicates the MASTER output left and right levels as controlled by the MASTER LEVEL (27).
