1. All instructions should be read before using this equipment.
2. To reduce the risk of electrical shock, do not open the unit. Please
refer all servicing needs to a Gemini-qualified service technician.
3. Do not expose this unit to direct sunlight or a heat source such as a
radiator or stove.
4. This unit should be cleaned only with a damp cloth. Avoid solvents or
other cleaning detergents.
5. When moving this equipment it should be placed in its original carton
and packaging. This will reduce the risk of damage during transit.
6. DO NOT EXPOSE THIS UNIT TO RAIN OR MOISTURE.
7. DO NOT USE SPRAY CLEANERS OR LUBRICANTS ON CON-
TROLS, SURFACES OR SWITCHES.
1. Before plugging this unit into any outlet, make sure that the VOLTAGE
SELECTION SWITCH (1) is set to the proper voltage. To change the
selection, unscrew the hard plastic protective top with a Phillips head
screw driver. Then use a flat head screw driver to move the switch to the
proper selection (115V/230V). Replace the hard plastic protective top,
and screw into the unit.
2. Ensure that the POWER (4) switch is in the OFF position prior to mak-
ing any connections. This unit comes with a power cord. Plug into the
rear panel POWER CORD (2) jack before plugging it into a proper power
source.
NOTE: LOCATED BY THE POWER CORD (2) JACK IS A 250V FUSE (3) TO PROTECT
AGAINST ELECTRICAL SURGES. TO REPLACE THE FUSE, PLACE A FLAT HEAD
SCREWDRIVER INTO THE GROOVE LOCATED INSIDE THE POWER CORD JACK (2) AND
POP THE FUSE OUT. REPLACE THE FUSE WITH ONLY A 250V FUSE.
3. The PS-04 has four outputs located on the rear panel:
- The MASTER RCA OUTPUT (5) connects the mixer to your main
amplifier using standard audio cables with RCA-type conectors.
- The BALANCED MASTER OUTPUT (8) connects the mixer to your
main amplifier using standard cables with 1/4" connectors. We recom-
mend using balanced cables if the distance to your amp is 10 feet or
more.
- The ZONE (7) output jacks allow the connection of an additional
amplifier with RCA cables.
- The REC (6) output jacks can be used to connect the mixer to the
record input of your recording unit, thus enabling you to record your mix
with RCA cables.
4. Headphones may be plugged into the front panel-mounted HEAD-
PHONES (22) ¼" jack.
5. Microphones may be plugged into the front panel-mounted MICRO-
PHONE (21) ¼" jack.
6. The PS-04 has 3 CONVERTIBLE PHONO/LINE (PH/LN) RCA
INPUTS (10, 14, 18) located on the rear panel on either side of the RCA
INPUTS. Facing the rear panel, the convertible RCA input on your right
is for PH1/LN1 (18). The convertible RCA input in the middle is for
PH2/LN3 (14). The convertible RCA input on your left is for PH3/LN5
(10). Using the PH/LN CONVERTERS (11, 15, 19), located just below
each input, you may convert the PH to LN and vice versa. Plug the
RCA's from your playable medium into each input to be connected to
their respective CHANNELS (CH). The PH INPUTS (10, 14, 18) only
accept turntables with a magnetic cartridge. The STEREO LN INPUTS
(9, 10, 13, 14, 17, 18) only accept line level inputs such as a CD, DAT,
Mini Disc, etc and require the proper switch settingand require the LN
switch setting as indicated in the PH/LN CONVERTER SWITCHES (11,
15, 19).
7. When using (a) turntable(s), you will need to ground the RCA cable(s)
by screwing in the grounding fork(s) to the TRIPLE GROUNDING
SCREWS (12 ,16, 20) located in the rear panel of the PS-04 mixer.
Attach each PH ground lines to one of the TRIPLE GROUND THUMB
SCREWS (12, 16, 20). These are to the right of each PH/LN CONVERT-
ER (11, 15, 19).
NOTE: WHEN USING TURNTABLES, NOT ATTACHING A GROUND MAY CAUSE A SYSTEM
"HUM."
1. Once all of your connections have been made in the rear panel, turn
on the mixer by pressing the POWER SWITCH (4).
2. CH1: To bring this channel into program output (PGM), you must first
decide which line will be in use. Use the LN SWITCH (23) to toggle from
PH1/LN1 (18) to LN2 (17) on this channel. Once you've selected the
proper line, slowly raise the CH1 FADER CONTROL (29) to a comfort-
able level. You can further modify the sound output of this channel by
adjusting the rotary GAIN (24), HIGH (25), MID (27), LOW (26) controls
located to the left of the CH1 FADER CONTROL (29).
3. CH2: To bring this channel into PGM, you must first decide which line
will be in use. Use the LN SWITCH (30) to toggle from PH2/LN3 (14) to
LN4 (13) on this channel. Once you've selected the proper line, slowly
raise the CH2 FADER CONTROL (36) to a comfortable level. You can
further modify the sound output of this channel by adjusting the rotary
GAIN (31), HIGH (32), MID (34), LOW (33) controls located to the left of
the CH2 FADER CONTROL (36).
4. CH3: To bring this channel in to PGM, you must first decide which line
will be in use. Use the LN SWITCH (37) to toggle from PH3/LN5 (10) to
LN6 (9) on this channel. Slowly raise the CH3 FADER CONTROL (43)
to a comfortable level, once you've selected the proper line. You can fur-
ther modify the sound output of this channel by adjusting the rotary
GAIN (38), HIGH (39), MID (41), LOW (40) controls located to the left of
the CH3 FADER CONTROL (43).
NOTE: FOR OPTIMAL PERFORMANCE, BEGIN PROGRAM MIX WITH ROTARY GAIN (24,
31, 38) CONTROLS SET TO MINIMUM (ROTATE IT TO THE COUNTER CLOCKWISE POSI-
TION). MAKE ALL ADJUSTMENTS IN SOUND OUTPUT WITH THE USE OF YOUR
CHANNEL FADER CONTROLS (29, 36, 43), ZONE (51), BALANCE (52), AND MASTER VOL-
UME (47) CONTROLS. THIS WILL PREVENT SIGNAL OVERLOAD AND DECREASE DIS-
TORTION. ONCE YOU HAVE MODIFIED YOUR SOUND AND WOULD LIKE TO INCREASE
THE OUTPUT OF YOUR SOUND, THEN YOU MAY ADJUST THE ROTARY GAIN CONTROL
IF NEEDED.
5. CUE: By connecting a set of headphones to the HEADPHONE (22)
jack, you can monitor any or all channels. Press the CUE BUTTONS
(28, 35, 42) for CH1 through CH3 to assign the CH(s) to be monitored in
your headphones. The respective CUE LED indicators will glow when in
use. Use the front panel located rotary CUE VOLUME CONTROL (44)
to adjust the CUE volume without changing the overall mix. By turning
the front panel located CUE/MIX/PGM (45) rotary control counter clock-
wise you will be able to monitor the assigned CUE signal. Slowly turning
the control clockwise to middle position (MIX) allows you to monitor CUE
mix with PGM. Moving the control clockwise to the right allows you to
monitor PGM output.
Use the CUE SPLIT/MIX SWITCH (48) to split the audio input playing
