SUGGESTION: You can use the Cut Features on each channel to
remove Low, Mid and/or High to create special effects.
6. CROSSFADER SECTION: The CROSSFADER (28) allows the mixing
of one source into another. The PS-1000 PRO features an
assignable crossfader. The ASSIGN (27, 29) switches allow you to
select which channel will play through each side of the crossfader.
The ASSIGN (27) switch has 5 settings (OFF, 1, 2, 3 or 4) and
allows you to select channel 1, 2, 3 or 4 to play through the left side
of the crossfader. The ASSIGN (29) switch has 5 settings (OFF, 1,
2, 3 or 4) and allows you to select channel 1, 2, 3 or 4 to play
through the right side of the crossfader. With the ASSIGN switch in
the off position, that side of the crossfader will be inactive. The
CROSSFADER (28) 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. OUTPUT CONTROL SECTION: The level of the AMP OUT (37, 49) is
controlled by the MASTER (34) slide and the BALANCE CONTROL
(33). The BOOTH (35) control adjusts the level of the BOOTH
OUTPUT (38). 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. Activating the MONO (32) button (the mono
LED will light) makes the master output mono.
8. 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 (9) controls MIC 1 and MIC
2 and has three settings. When the MIC/TALKOVER SWITCH (9) is
in the left position, MIC 1 and MIC 2 and talkover are off. When the
MIC/TALKOVER SWITCH (9) is in the center position MIC 1 and MIC
2 are on, the MIC INDICATOR (8) will glow, but talkover is off.
When the MIC/TALKOVER SWITCH (9) 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 (4) and
BASS (5) controls allow you to fully adjust the tone of MIC 1 and MIC
2. MIC 1 LEVEL (7) controls the level of MIC 1. The MIC 2 LEVEL
(6) controls the level of MIC 2.
9. CUE SECTION: By connecting a set of headphones to the
HEADPHONE (13) jack, you can monitor any or all of the channels.
Press the CUE ASSIGN (20) 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 (10) control to adjust the
cue volume without effecting the overall mix. By rotating the CUE
PGM PAN (12) control to the left you will be able to monitor the
assigned cue signal. Rotating to the right will monitor the PGM
(program) output. Use the CUE SPLIT (11) button to split the signals
from cue and program so that cue will be heard in one earphone and
program will be heard in the other earphone.
10. DISPLAYS: The PEAK HOLD LED METER (30) indicates the
MASTER OUTPUT (37, 49) left and right channel levels. The
individual channels each have their own PREFADER INPUT LEVEL
PEAK HOLD LED METERS (31) which reflect the GAIN (14), HIGH
(15), MID (16), and LOW (17) rotary control adjustments. The
CHANNNEL SLIDES (19, 22, 24, 26) will not effect the PREFADER
INPUT LEVEL PEAK HOLD LED METERS (31).
