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 1-732-969-9000 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 (2) 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.
3. The BPM-150 is supplied with 2 sets of output jacks. The OUTPUT
AMP (3) jacks are used to connect to your main amplifier. The
OUTPUT REC (5) jacks can be used to connect the mixer to the
record input of your recorder enabling you to record your mix.
4. The DJ MIC (26) input (found on the front panel) accepts a 1/4"
connector and balanced and unbalanced microphones.
5. On the rear panel are 2 stereo PHONO/LINE (7, 11) inputs, 1 stereo
PHONO (12) input and 1 stereo LINE (6) input. The PHONO/LINE
SWITCHES (8, 10) enable you to set the (7, 11) inputs to Phono or
Line. The phono inputs will accept only turntables with a magnetic
cartridge. A GROUND SCREW (9) 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 (38) jack.
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 (4) in the left
position).
2. Then turn the power off before moving the GROUND LIFT
SWITCH (4). 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 (1) switch.
2. CHANNEL 1: The GAIN (13), HIGH (20), MID (21), and LOW (22)
controls allow you to fully adjust the selected source. Switch # (23)
allows you to select either the PHONO 1 (12) or the PHONO 2/LINE 1
(11) input. The CHANNEL SLIDE (24) controls the output level of this
channel.
3. CHANNEL 2: The GAIN (39), HIGH (32), MID (33), and LOW (34)
controls allow you to fully adjust the selected source. Switch # (35)
allows you to select either the PHONO 3/LINE 2 (7) or the LINE 3 (6)
input. The CHANNEL SLIDE (36) controls the output level of this
channel.
NOTE
: There is Low, Mid and High equalization for each
channel with an extremely wide range of adjustment giving
you a smoother mix.
SUGGESTION: You can use the Cut Features on each channel to
remove Low, Mid and/or High to create special effects.
4. CROSSFADER SECTION: The CROSSFADER (31) allows the mixing of
one source into another. The left side of the CROSSFADER (31) is
CHANNEL 1 and the right side is CHANNEL 2. The CROSSFADER (31)
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.
