USING HEADPHONES

To listen in privacy or monitor the audio source inputs so you can locate
an exact passage or section before mixing it, plug a pair of stereo
headphones (not supplied) with a 1/4-inch plug into PHONES on the mixer's
lower right front corner.  Your local Radio Shack store carries a wide
selection of headphones.

Listening Safely

Do not listen at extremely high volume levels.  Extended, high-volume
listening can lead to permanent hearing loss.  Follow these guidelines to
protect your hearing, especially when you use headphones.

    Always start by setting the volume to the lowest level possible before
    you begin listening.

    Put the headphones on, then gradually increase the volume as necessary.

    Once you set the volume, do not increase it.  Over a period of time,
    your ears adapt to the volume level, so a volume level that does not
    cause discomfort might still damage your hearing.

CAUTION:  As you begin to mix, be careful not to get into the habit of
          always increasing volume levels to achieve the proper balance.
          You can bring high levels down just as easily as you can bring
          low levels up.  Try to keep the independent level controls in the
          middle position (3 to 8).  Listening at excessive volume levels
          will soon give you "tired ears" and you won't be as pleased with
          your finished product later.

USING THE CONTROLS

Turning on the Mixer

1.  Set POWER ON/OFF to ON to turn on the mixer's power.  The VU meter's
    indicator lights.

NOTE:  To avoid a possible popping sound, always turn on the mixer before
       you turn on the amplifier.

2.  Turn on the output amplifier and temporarily set its volume to the
    minimum setting.

3.  To monitor the audio input sources so you can decide when to mix in
    each input, see "Monitoring the Inputs."

    To mix the audio input sources so you can play them through your
    amplifier system or record them on your tape deck, as "Mixing the
    Inputs."

Monitoring the Inputs

You can monitor the audio input sources before mixing them so you can
decide when to mix in each input.

Follow these steps to monitor the audio input sources.

1.  Perform Steps 1 and 2 of "Turning on the Mixer," and put the
    headphones on.

2.  Set MONITORING SOURCE to the audio input source (MIC, 1, 2, 3, or 4)
    you want to monitor.

3.  Set the desired audio input source's volume to its minimum setting,
    turn it on, and set it to play (or continuously talk into the
    microphone).

4.  Gradually increase the audio source's volume control to a comfortable
    setting.

5.  Repeat Steps 1-3 to select and monitor any other audio input source.

Mixing the Inputs

You can select any or all of the six audio input source for mixing.

1.  Perform Steps 1 and 2 of "Turning on the Mixer."

2.  Set the selected audio input source's volume to its minimum setting,
    turn it on, and set it to play (or continuously talk into the
    microphone).

3.  Set the corresponding MIC, PHONO 1, PHONO 2, CD 1/VIDEO, CD 2/LINE
    volume level control to approximately 8-10.

4.  When adding an audio input source, adjust the corresponding volume
    level control so you get an average reading of 0 on both output level
    VU meters.

NOTE:  The output level VU meters indicate the combined output signal
       level of:

       All the input sources being mixed.

       Both the left and right stereo channel outputs.

5.  Adjust the output amplifier's volume level control to the desired
    volume.

6.  When finished mixing, turn off all the audio input sources.

7.  To turn off the mixer, set POWER ON/OFF to OFF.  The VU meter's light
    turns off.
