8. EQUALIZER: This unit features dual 7 band GRAPHIC EQUALIZERS
(8, 22) that allow you to adjust the sound to fit any room. Activate
the equalizer by pressing EQ BUTTON (28) (EQ LED is illuminated).
By adjusting any of the 7 LEFT equalizer slide controls (8), you can
cut or boost the tonal characteristics of the sound coming from the
LEFT speaker by ±12 dB. Adjusting any of the 7 RIGHT equalizer
slide controls (22) allows you to cut or boost the tonal
characteristics of the sound coming from the RIGHT speaker by ±12
dB. Deactivate the equalizer by pressing the EQ BUTTON (28) again
(EQ LED is OFF).
9. OUTPUT CONTROL: The level of the MAIN OUTPUT (34) is
controlled by the MASTER (24) slide. Activating the MONO (23)
button (MONO LED is illuminated) converts the overall output to
mono. The BOOTH (29) control adjusts the level of the BOOTH
OUTPUT (35).
HINT: BOOTH OUTPUT IS USED BY SOME DJS TO RUN
MONITOR SPEAKERS IN THE DJ BOOTH. IT IS ALSO USED AS
A SECOND ZONE OR AMP OUTPUT.
NOTE: REC OUTPUT HAS NO LEVEL CONTROL. LEVEL IS
CONTROLLED WITH THE CHANNEL SLIDES OF THE SELECTED
CHANNEL(S). TONE IS CONTROLLED VIA THE EQUALIZERS.
10.TALKOVER: The purpose of the talkover is to allow the program
playing to be muted so that the mic may be heard above the music.
The MIC/TALKOVER SWITCH (7) controls MIC 1 and MIC 2 and
has three settings.
• When MIC/TALKOVER (7) is in the BOTTOM position,
MIC 1, MIC 2 and TALKOVER are all OFF.
• When MIC/TALKOVER (7) is in the CENTER position, MIC 1
and MIC 2 are ON. MIC INDICATOR (6) glows/TALKOVER is OFF.
• When MIC/TALKOVER SWITCH (7) is in the TOP position,
MIC 1, MIC 2 and TALKOVER are ON and the volume of all
sources except MIC inputs is lowered by 16 dB.
11. TREBLE (2) and BASS (3) controls allow you to adjust the tone
of MIC 1 and MIC 2. MIC 1 LEVEL (5) controls the level of MIC 1
while MIC 2 LEVEL (4) controls the level of MIC 2.
12.CUE: By connecting a set of headphones to the HEADPHONE (32)
jack, you can monitor any or all channels. Press CUE ASSIGN (20)
buttons for Channels 1 through 4 and select the Channel(s) to be
monitored. The respective LED indicators will glow. Use the CUE
LEVEL (31) control to adjust the cue volume without changing the
overall mix. By moving the CUE PGM PAN (30) control to the LEFT
you will be able to monitor the assigned cue signal. Moving the
control to the RIGHT allows you to monitor PGM (program) output.
13.DISPLAY: The DISPLAY (21) indicates the MASTER output of the
left and right levels.
