1. All operating instructions should be read before using this equipment.
2. To reduce the risk of electrical shock, do not open the unit. There are
NO USER REPLACEABLE PARTS INSIDE. Please refer servicing to a
qualified service technician.
3 Do not expose this unit to direct sunlight or to 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.
CAUTIONS
DO NOT EXPOSE THIS UNIT TO RAIN OR MOISTURE.
DO NOT USE ANY SPRAY CLEANER OR LUBRICANT ON ANY
CONTROLS OR SWITCHES.
CONNECTIONS
1. Before plugging in the power cord, make sure that the VOLTAGE
SELECTOR (65) switch is set to the correct voltage.
Note: This product is double insulated and not intended to be grounded.
2. Make sure that the POWER (1) switch is in the off position. The
POWER LED (2) will be off.
3. The PS-924 is supplied with 3 sets of output jacks. The OUTPUT
AMP (66) jacks are used to connect to your main amplifier. The
OUTPUT REC (67) jacks can be used to connect the mixer to the
record input of your recorder enabling you to record your mix. The
OUTPUT BOOTH (68) jacks allow you to hook up an additional
amplifier.
4. The PS-924 is equipped with 2 microphone inputs. The DJ MIC (3)
input (found on the front panel) accepts 1/4" or XLR connectors and
suitable for balanced or unbalanced microphones. The AUX MIC
(69) input (found on the rear panel) is a 1/4" jack for an unbalanced
microphone.
5. On the rear panel are 2 stereo PHONO (70, 71) inputs, 6 stereo LINE (72,
73, 74, 75, 76, 77) inputs and 1 mono AUX LINE (78) input. The stereo
phono inputs will accept only turntables with a magnetic cartridge. A
GROUND (79) screw for you to ground your turntables is located on the
rear panel. The stereo line inputs will accept any line level input such as
a CD player, a cassette player, etc.
Note: The AUX LINE (78) input is composed of 2 RCA jacks. When
connecting a mono line level source, either jack can be used. By
connecting a stereo line level device to both jacks, the input will be
combined to one mono signal.
6. Headphones can be plugged into the front panel mounted
HEADPHONE (4) jack.
7. The PS-924 comes with a front panel XLR LIGHT (5) jack. This jack
is for use with a gooseneck light like the Gemini GNL-500. NEVER
plug a microphone into this jack.
8. If you are using an off board signal enhancer, you can use the SEND
(80) output to send the signal to the device and the RECEIVE (81)
input jacks to bring the signal back in to the PS-924.
9. The PS-924 is supplied with DJ MIC LOOP (82) jacks that can be
used to add an audio enhancer such as a key controller to the mic
circuit. There must be a connection to these jacks. If no device is
being used in the DJ mic loop, then the jumper wire, (included), must
be in place.
OPERATION
1. POWER ON: Once you have made all the equipment connections to
your mixer, press the POWER SWITCH (1). The power will turn on
and the POWER LED (2) will glow RED.
2. DJ MIC SECTION: The GAIN (6), TREBLE (7), MID (8), BASS (9),
PAN (10) and LEVEL (11) controls allow full adjustment of the DJ mic
that is plugged into the DJ MIC (3) input.
Note: The OVERLOAD LED (12) glows red when the DJ mic is being
over driven. To correct the setting, turn down the GAIN (6) control
until the LED goes off.
3. AUX CHANNEL: By using the AUX MIC/LINE (13) switch, you can
choose between an additional mic or an additional mono line input.
The GAIN (14), TREBLE (15), MID (16), BASS (17), PAN (18) and
LEVEL (19) controls fully adjust the Aux Channel input you selected
with the AUX MIC/LINE (13) switch.
Note: The OVERLOAD LED (20) glows red when the Aux Channel is
being over driven. To correct the setting, turn down the GAIN (14)
control until the LED goes off.
HINT: Like the DJ Mic, the Aux Channel is always live. Hooking up another mic or
a mono line device such as a sound effects generator or a drum machine, will allow
you to play the selected source at any time.
4. MAIN CHANNEL SECTION: To assign an input source to a channel,
set the PHONO/LINE (29,30) and the LINE/LINE (31, 32) switches to
their appropriate positions. To make the proper adjustments to your
music, set the TREBLE (21), MID (22), BASS (23) and GAIN (24)
controls and the CHANNEL (25, 26, 27, 28) slides.
5. CROSSFADER SECTION: The CROSSFADER (38) allows the mixing
of one source into another. The PS-924 features an assignable
crossfader. The ASSIGN (39,43) switches allow you to select which
cannel will play through each side of the CROSSFADER. ASSIGN
(39) switch allows you to select channel 1, 2, 3 or 4 to play through
the left side of the CROSSFADER. ASSIGN (43) switch does the
same to the right side of the CROSSFADER. Each assign switch has
its own OFF (40) switch and OFF INDICATOR (41) LED. With the
OFF (40) switch in the off position (the OFF INDICATOR (41) glows
red), that side of the CROSSFADER (38) will be inactive.
HINT: Try using the OFF (40) switches when you are changing the ASSIGN (39,43)
switch settings. For Example: Assume that you have a turntable hooked up to
channel 1, a tape deck hooked up to channel 2 and a CD player hooked up to
channel 3. The left side ASSIGN (39) switch is set to 1, the right side ASSIGN (43)
is set to 2, and the CROSSFADER (38) is all the way to the right. Under this set of
circumstances, channel 2 will be playing your tape deck. Now suppose you want
to change the left side ASSIGN (39) switch to # 3 so that you can use your CD
player. You must turn the left side ASSIGN (39) off by pressing the OFF (40) Switch
(the OFF INDICATOR (41) glows red). Then you can make your changes to the
setting. Reactivate the ASSIGN (39) switch by pressing the OFF (40) switch (the
OFF INDICATOR (41) goes off). Failure to do this will result in an audio glitch when
the assign (39) switch setting is changed.
The CROSSFADER (38) in your unit is REMOVABLE and if the need
arises can be easily replaced. Crossfader units are available in two
sizes. Part # RF-45 (which is identical to the crossfader supplied
with the PS-924) has a 45 mm travel from side to side. Also available
is part # RF-30 which has a 30 mm travel distance Just purchase
either of these crossfader units from your Gemini dealer and follow
these instructions:
