PRESETTING THE CONTROLS

Warning:  A sudden high output from the mixer could damage the audio
          devices connected to the mixer's output and your hearing,
          especially if you use headphones.

To avoid accidentally overdriving a channel or prematurely mixing in an
audio input, adjust the mixer's controls to these settings before you
connect the AC power cord or turn on power.

CONNECTING THE OUTPUTS

To avoid sudden and unusable sound outputs from the audio devices, adjust
the audio devices' controls to these settings before you connect the
mixer's output jacks to the audio devices' input jacks.

     Audio Device    Control    Setting

     Tape Deck       Power      OFF
     Amplifier/      Power      OFF
     Receiver        Tone       FLAT

To play the mixer's output signal through your speaker system (for events
such as parties, dances, conferences, etc.), connect an audio patch cord
(not supplied) from the mixer's OUTPUT R and L jacks to your receiver/
amplifier's left and right auxiliary input jacks.

To record the mixer's output signal, connect an audio patch cord (not
supplied) from the mixer's REC R and L jacks to your tape deck's left and
right input jacks.

CONNECTING THE INPUTS

You can connect up to five audio input sources (such as a tuner, tape
deck, CD player, magnetic-cartridge turntable, camcorder, or VCR) to the
input jacks on the back of the mixer.

CAUTION:  Do not connect an audio source with a high-level output to the
          low-level MIC, PHONO 1, or PHONO 2 audio input jacks.  An audio
          source's output is high-level if you can raise or lower its
          volume with its volume control.

NOTE:  To connect a monaural audio input device to any of the mixer's
       stereo low- or high-level input jacks, use a shielded Y-adapter
       (such as Cat. No. 42-2156).

1.  Connect a microphone (not supplied) with a 1/4-inch plug to MIC on the
    back of the mixer.

    NOTE:  Your local Radio Shack store carries a wide selection of
           microphones.

2.  Connect up to two low-level output audio sources (such as a magnetic-
    cartridge turntable) to PHONO 1 and PHONO 2.

    NOTES:  If you connected magnetic cartridge turntables, connect their
            ground wires (usually black or green) to GND.

            You can connect any audio source's low-level output to either
            PHONO 1 or PHONO 2.

3.  Connect up to two high-level output audio sources (such as a tuner,
    tape deck, CD player, camcorder, or VCR) to CD 1/Video and CD 2/Line.

    NOTE:  You can connect any high-level output audio source to CD 1/VIDEO
           and CD 2/LINE.

4.  Connect the small end of the supplied AC adapter to the AC 18V jack on
    the back of the mixer and connect the other end to a standard AC
    outlet.

CAUTION:  The supplied adapter is UL listed.  It supplies 18 volts AC and
          delivers the required 300 milliamps to the mixer.  The center
          tip is set to negative and its plug properly fits the mixer's
          AC 18V jack.  Using an adapter that does not meet these speci-
          fications could seriously damage the mixer or the adapter.
