changing the ASSIGN setting. This will avoid any click or popping sound
in your signal while you are changing the assign setting. The
CROSSFADER (22) in your unit is removable and if the need arises can
be easily replaced. Crossfader units are available in three varieties. Part
# RF-45 (which is identical to the crossfader supplied with the mixer) has
a 45 mm travel from side to side. Part # RF-30 is available with a 30 mm
travel distance. Also available is the PSF-45 with a special curve
designed for scratch mixing. Just purchase one of these crossfader units
from your Gemini dealer and follow these instructions:
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.
7. BEAT INDICATORS: Each side of the CROSSFADER (22) has it’s own
BEAT INDICATOR (21). They flash at the low frequency peak level
allowing you to match the beats visually.
8. OUTPUT CONTROL SECTION: The level of the AMP OUT (39, 40) is
controlled by the MASTER (32) and the BALANCE (31) controls. The
BOOTH (30) control adjusts the level of the BOOTH OUTPUT (41).
HINT: The booth OUTPUT is used by some DJs to run monitor
speakers in their DJ booth. You can also use it as a second ZONE or
AMP output.
9. 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. The MIC/TALKOVER SWITCH (28) controls MIC 1 and MIC
2 and has three settings. When the MIC/TALKOVER SWITCH (28) is
in the left position, MIC 1 and MIC 2 and talkover are off. When the
MIC/TALKOVER SWITCH (28) is in the center position MIC 1 and MIC
2 are on, the MIC INDICATOR (29) will glow, but talkover is off. When
the MIC/TALKOVER SWITCH (28) is in the right position, MIC 1 and
MIC 2 and talkover will be on and the volume of all sources except the
Mic inputs are lowered by 16 dB. The TREBLE (24) and BASS (25)
controls allow you to fully adjust the tone of MIC 1 and MIC 2. MIC 1
LEVEL (26) controls the level of MIC 1. The MIC 2 LEVEL (27)
controls the level of MIC 2.
10. CUE SECTION: By connecting a set of headphones to the
HEADPHONE (2 OR 23) jack, you can monitor any or all of the
channels. Press the CUE ASSIGN (8) buttons for channels 1 - 4 to
select the channel or channels to be monitored and their respective
LED indicators will glow. Use the CUE LEVEL (33) control to adjust the
cue volume without effecting the overall mix. By sliding the CUE PAN
(35) control to the left you will be able to monitor the assigned cue
signal. Sliding to the right will monitor the PGM (program) output.
Activating the multifunction CUE X-F SPLIT (34) converts the CUE
PAN (35) control so that it fades between the two channels assigned to
the crossfader and splits the signals so that the left side will be heard
in the left headphone and the right side will be heard in the right
headphone.
11. DISPLAY: The peak hold, dual function DISPLAY (36) indicates either
the MASTER (39, 40) output left and right levels OR the the selected
cue and program (premaster output) levels. You can choose the option
you want by pressing the DISPLAY (37) button.
NOTE: When the DISPLAY (36) is in the cue/program mode,
by adjusting the individual channel level slides, you can
increase or decrease the signal to match the other
channel’s signal.
