Audio Mixer with Echo (Rack Mount Type)

You can mix up to 6 inputs at the same time and use the built in equalizer
and echo generator to tailor the sound as desired.

1.  Set MASTER to approximately 5.

2.  Set the switch above each volume control to select the input you want
    to activate.  For example, set MIC HI/Low to HI when you use a high
    impedance microphone, or LOW when you use a low impedance microphone.

3.  Adjust the corresponding volume level control to obtain a reading of 0
    on the OUTPUT LEVEL VU  meters.

Note:  The OUTPUT LEVEL VU  meter indicates the output signal levels of the
       left and right channels.

4.  Adjust MIC Level clockwise to increase the main (DJ) microphone's
    volume; rotate it counterclockwise to decrease the volume.

5.  Set ECHO BYPASS/ON to ON to produce an ECHO effect and to BYPASS to
    eliminate the ECHO effect.

6.  Push in EQUALIZER BYPASS/ON to ON to operate the right and left 7
    -channel frequency equalizer controls.

7.  When two turntables (or other audio components connected to the PHONO 1
    and PHONO 2 inputs) are playing at the same time, slide FADER (PHONO 1/
    PHONO 2):

*   left, to fade in the volume of PHONO 1 and fade out the volume of
    PHONO 2.

*   Right, to fade in the volume of PHONO 2 and fade out the volume of
    PHONO 1.

Note:  this lets you quickly and smoothly change from playing PHONO 1 to
       playing PHONO 2 (or vice versa).

8.  Set the MASTER volume to the desired volume.

9.  Set POWER OFF/ON to OFF to turn off the mixer's power.  The VU meters'
    lights go off.

USING THE "DJ'S MICROPHONE

NORMAL

For equal blending of voice and music, set NORMAL/STANDBY/TALKOVER to
NORMAL.  In the NORMAL mode, the "DJ" MIC input is mixed to blend equally
with all the main volume inputs (MIC, PHONO 1, PHONO 2, LINE 1 and LINE 2)
You can adjust MIC LEVEL to increase the microphone level without affecting
the main volume inputs.

Standby

To disable the DJ's MIC input microphone, set NORMAL/STANDBY/TALKOVER to
STANDBY.

Note:  Set MIC LEVEL to minimum (full counterclockwise) when the microphone
       is not in use.

Talkover

Start with a microphone level that gives a VU reading of 5 to 3.

To talk over music, set NORMAL/STANDBY/TALKOVER  to TALKOVER.  The mixer
automatically reduces tall the main volume inputs (MIC, PHONO 1, PHONO 2,
LINE 1, and LINE 2) just enough for you to hear yourself in the headphones
or speakers (over the music).

When you finish speaking, set NORMAL/STANDBY/TALKOVER TO STANDBY.  The
mixer automatically returns all the mail volume inputs to their original
levels.

USING ECHO

The echo mode is applied to the sound after all the inputs are mixed.

Set ECHO BYPASS/LOW to ON to turn on the echo mode and activate the DELAY
and REPEAT functions.  Set ECHO BYPASS/ON to BYPASS  to turn off the echo
mode.

The DELAY control lets you induce a measured time delay to simulate an
echo.  Set DELAY to full counterclockwise for a minimum time delay and to
full counterclockwise for a maximum time delay.

The REPEAT control lets you control the length of time a tone is repeated
(reverberation).  Set REPEAT to 10 for the longest time and to 0 for the
shortest time.

USING THE 7-BAND FREQUENCY EQUALIZER

With the seven sliding frequency controls, you can tailor the sound
processed through the mixer to fit the acoustic surrounding s and your
personal taste.

Each control varies by +/- 12 dB the level of a narrow band of frequencies
centered around the frequency noted between the controls 60 Hz, 150 Hz, 400
Hz, 1 kHz, 2.4 kHz, 6 kHz, and 15 kHz).

Set the EQUALIZER BYPASS/ON switch to ON to turn on the frequency
equalizer.  Then slide the control up to boost the indicated frequency
range or down to reduce it.

Notes:

*  If you set the control to the center position, the frequency range is
   unaltered.

*  In order to provide smooth frequency control, the effect of these
   controls must overlap slightly.  Thus the 1 KHZ control has a slight
   effect on the range of frequencies covered by the 400 Hz and the 2.4 KHZ
   controls.

60 Hz    Adjusts the frequencies in the low bass range (low organ notes and
         bass drums.  Reduces rumble or other low-frequency noise.

150 Hz   Adjusts the frequencies in the low to middle bass range (low organ
         notes, bass drums, timpani and some low bass).

400 Hz   Adjusts frequencies in the middle-bass range timpani and some low
         -bass instruments).

1 kHz    Adjusts the range of frequencies in the middle frequency range
         where the ear is most sensitive (vocals).

2.4 kHz  Adjusts the range of frequencies in the upper middle frequency
         range that include vocals and some upper-midrange instruments
         (clarinet and saxophone).

6 kHz    Adjusts the range of frequencies in the lower high frequency range
         that include flutes, oboes, violins, piccolos, and other treble
         instruments.  Boosting this range adds vibrancy to the upper
         voices.  Too much boost can make the music sound harsh.

15 kHz   Adjusts high- frequency sound (cymbals, flutes, and violins).

Set the EQUALIZER BYPASS/ON switch to BYPASS  to turn off the frequency
equalizer and disable the frequency controls.
