Dsp Signal Processor; Specifications - Gemini FX-7000 Service Manual

10.MIC 1/TALKOVER: 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 1/TALKOVER SWITCH (47) controls MIC 1 (19)
and has three settings. When the MIC 1/TALKOVER SWITCH (47) is
in the "OFF" position, MIC 1 and TALKOVER are off. When the MIC/
TALKOVER SWITCH (47) is in the "MIC 1" position MIC 1 is on, the
MIC/TALKOVER LED (48) will glow, but TALKOVER is off. When the
MIC/TALKOVER SWITCH (47) is in the "TALKOVER" position, MIC 1
and TALKOVER will be on and the volume of all sources except the
MIC 1 input are lowered by 16 dB. The HIGH (51) and LOW (50)
CONTROLS allow you to fully adjust the tone of MIC 1. MIC 1 LEVEL
(49) controls the level of MIC 1.
11.CUE SECTION: By connecting a set of headphones to the
HEADPHONE (20) jack, you can monitor any or all of the channels.
Press the CUE ASSIGN BUTTONS (29, 30, 31,) for CHANNELS 1-3 to
select the channel or channels to be monitored and the buttons will
illuminate. Use the CUE LEVEL (44) control to adjust the headphone
volume without affecting the overall mix. By rotating the CUE PGM
PAN (43) control to the left you will be able to monitor the assigned cue
signal. Rotating to the right will monitor the PGM (program) output.
Pressing the CUE SPLIT (42) button lets you hear the CUE on the left
side earphone and the PGM (program) on the right. Pressing the CUE
EFFECT (32) button allows you to send your EFFECT output to your
CUE MIX.
12.VU METER MODE: The peak hold, dual function VU METER (40)
indicates either the MASTER (38) output left and right levels, or the
CUE and PGM (program) levels. You can choose the option you want
by pressing the VU METER MODE (41) button.

DSP SIGNAL PROCESSOR:

DSP EFFECT (25): Tap the DSP EFFECT (25) button to turn ON or turn
OFF the desired effect.
CHANNEL SELECTOR (52): The channel selector is for selecting the
channel you want the effect to have effect on. Use the CHANNEL
SELECTOR (52) to select CHANNELS 1, 2, 3, MIC 1, or the MASTER
output. To hear it before you mix it in the PGM (program) use the
CUE EFFECT (32) button.
EFFECT SELECTOR (53): Turning this knob selects the effect (1-16);
refer to D.S.P. EFFECTS (54) for which effect you want to use.
Displayed by the PARAMETER LED DISPLAY (55). The effects
parameters (1-99) can be adjusted using the PARAMETER (56) knob.
DSP EFFECTS (54): All the DSP effects are listed on the mixer here.
Turning the PARAMETER (56) knob clockwise increases the effect in
most cases. Here is a brief explanation of their uses:
01. SEND/RETURN: Used to connect outboard effect units.
02. DELAY: Delay effect; adjust time with PARAMETER (56) knob.
03. ECHO REGULAR: Echo effect, adjust time like delay effect.
04. PING PONG ECHO: Echo effect with left/right panning, adjust time
like delay effect.
05. REVERB: Reverb effect for depth, adjust time just like delay effect.
06. PITCH UP: Increases the pitch of the selected CHANNEL, Mic 1 or
MASTER (PGM).
07. PITCH DOWN: Decreases the pitch of the selected CHANNEL, MIC 1
or MASTER (PGM).
08. FILTER 1: Low pass filter increases with clockwise knob movement.
09. FILTER 2: High pass effect increases with clockwise knob movement.
10. BRAKE: Simulates the manual stop of a record on a turntable.
11. AUTO PAN: Automatic panning from left to right, turning knob
clockwise increases the effect speed.
12. FLANGER: Flanger sound is an effect, which is often referred to as a
"whooshing" or "airplane fly-by" sound, turning knob clockwise
increases the intensity of the effect.
13. PHASER: Very close to flanger, phaser is a similar but different effect.
14. ROTARY: Simulates a rotating speaker effect.
15. AMBIENCE: Adds ambient effect to mix.
16. PRESET REVERBS: F1. HALL 1, F2. HALL 2, F3. ROOM 1, F4. ROOM 2,
F5. ROOM 3, F6. PLATE 1, F7. PLATE 2, F8. PLATE 3, F9. ROOM CHORUS
PARAMETER LED DISPLAY (55): The PARAMETER LED DISPLAY (55)
displays which effect is chosen as well as the parameters.
PARAMETER (56): The PARAMETER (56) knob changes the effects
parameters from (1-99), except for effect number 1. However effect
number 16, has 9 different preset reverb settings (F1- F9).
WET/DRY (57): Turning the WET/DRY (57) knob lets you pan the selected
effect into and out of the PGM (program)
