Cautions
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.
In the U.S.A., if you have any problems with this unit,
call 1-732-738-9003 for customer service. Do not return
equipment to your dealer.
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.
6. DO NOT EXPOSE THIS UNIT TO RAIN OR MOISTURE.
7. 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 (40) 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 (33) switch is in the off position. The
POWER LED (34) will be off.
3. The PDM-18 is supplied with 3 sets of amp output jacks. The MAIN
OUTPUT (41) jacks are unbalanced and used to connect to your
main amplifier. The REC OUTPUT (43) jacks can be used to connect
the mixer to the record input of your recorder enabling you to record
your mix. The BOOTH OUTPUT (42) jacks allow you to hook up an
additional amplifier.
4. The MIC 1 (1) input (found on the front panel) accepts a 1/4" or XLR
connector.
The MIC 2 (55) input (found on the rear panel) accepts
1/4" connectors. All accept balanced and unbalanced microphones.
5. On the rear panel are 3 stereo PHONO/LINE (47, 50, 53) inputs and
5 stereo LINE (44, 45, 46, 49, 52) inputs. The PHONO/LINE
SWITCH (48) enables you to set the (47) input to Phono or Line. The
PHONO/LINE SWITCH (51) enables you to set the (50) input to
Phono or Line. The PHONO/LINE SWITCH (54) enables you to set
the (53) input to Phono or Line. The phono inputs will accept only
turntables with a magnetic cartridge. A GROUND SCREW (56) 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.
6. Headphones can be plugged into the front panel mounted
HEADPHONE (39) jack.
7. The PDM-18 comes with a front panel BNC LIGHT (32) jack. This
jack is for use with a gooseneck light like the Gemini GNL-700.
Using the Ground Lift Switch
Depending on your system configuration, sometimes applying the
ground will create a quieter signal path. Sometimes lifting the ground
can eliminate ground loops and hum to create a quieter signal path.
1. With the mixer on, listen to the system in idle mode (no signal
present) with the ground applied (the GROUND LIFT SWITCH (57) in
the left position).
2. Then turn the power off before moving the GROUND LIFT
SWITCH (57). Lift the ground by moving the GROUND LIFT
SWITCH to the right, turn the power back on and listen to determine
which position will provide a signal devoid of background noise and
hum. Keep the GROUND LIFT SWITCH in the ground position if the
noise level remains the same in either position.
CAUTION: DO NOT TERMINATE THE AC GROUND ON THE POWER
MIXER IN ANY WAY. TERMINATION OF THE AC GROUND CAN BE
HAZARDOUS.
Operation
1. POWER ON: Once you have made all the equipment connections to
your mixer, press the POWER SWITCH (33). The power will turn on
and the POWER LED (34) will glow RED.
2. CHANNEL 1: Switch # (9) allows you to select the PHONO 1/LINE 1
(55) or the LINE 2 (54) input. The CHANNEL SLIDE (10) controls the
input level of this channel.
3. CHANNEL 2: Switch # (11) allows you to select the PHONO 2/LINE
3 (52) or the LINE 4 (51) input. The CHANNEL SLIDE (12) controls
the input level of this channel.
4. CHANNEL 3: Switch # (13) allows you to select the PHONO 3/LINE
5 (49) or the LINE 6 (48) input. The CHANNEL SLIDE (14) controls
the input level of this channel.
5. CHANNEL 4: Switch # (15) allows you to select the LINE 7 (47) or
the LINE 8 (46) input. The CHANNEL SLIDE (16) controls the input
level of this channel.
6. CROSSFADER SECTION: The CROSSFADER (18) allows the
mixing of one source into another. The PDM-18 features an
assignable crossfader. The ASSIGN (17, 19) switches allow you to
select which channel will play through each side of the crossfader.
The ASSIGN (17) 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 (19) 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 (18) 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:
