3. The PMX-1400, PMX 1800, and PMX 2400 are supplied with 4 sets of
output jacks:
• The BALANCED MASTER OUTPUT (4) jacks connect the mixer to
main amplifier using standard cables with 1/4” connectors. We recommend
using balanced cables if the distance to your amp is 10 feet or more.
• The AMP OUTPUT (5) jacks also connect to the main amplifier.
• The BOOTH OUTPUT (6) jacks allow the connection of an additional amplifier.
• The REC OUTPUT (7) jacks can be used to connect the mixer to the
record input of your recording unit, thus enabling you to record your mix.

connector. The MIC 2 (20) input (on the rear panel) accepts 1/4"
connectors. Both accept balanced and unbalanced microphones.

for use with a (not provided) gooseneck light such as the Gemini GNL-700.
USING THE GROUND LIFT SWITCH:
Depending on your system configuration, application of the ground will
sometimes create a quieter signal path. Lifting the ground occasionally
eliminates ground loops and “hum” to create a quieter signal.
1. With the mixer ON, listen to the system in “idle” mode (no signal
present) and with the ground “applied” and the GROUND LIFT SWITCH
(24) in the LEFT position.
2. Turn the power OFF before moving the GROUND LIFT SWITCH (24).
“Lift” the ground by moving the GROUND LIFT SWITCH (24) to the
RIGHT, turn the power back ON and listen to determine which position
provides a signal devoid of background noise and hum. Keep the
GROUND LIFT SWITCH (24) in the “ground” position if the noise level
remains the same in either position.
CAUTION: DO NOT TERMINATE THE AC GROUND ON THE MIXER CABLE. TERMINATION OF
THE AC GROUND CAN BE HAZARDOUS!
OPERATION:
1. POWER: Once you have made all the equipment connections to your
mixer, press the POWER (2) switch. The power will turn on and the
POWER LED (3) will glow RED.
2. CHANNEL 1: Switch (25) allows you to select PHONO 1/LINE 1 (17) or
the LINE 2 (16) input. CHANNEL SLIDE (26) controls the input level of
this channel.
3. CHANNEL 2: Switch (27) allows you to select PHONO 2/LINE 3 (14) or
the LINE 4 (13) input. CHANNEL SLIDE (28) controls the input level of
this channel.
4. CHANNEL 3: Switch (29) allows you to select PHONO 3/LINE 5 (11) or
the LINE 6 (10) input. CHANNEL SLIDE (30) controls the input level of
this channel.
5. CHANNEL 4: Switch (31) allows you to select either the LINE 7 (9) or
LINE 8 (8) input. CHANNEL SLIDE (32) controls the input level of this
channel.
6. CROSSFADER: The CROSSFADER (33) allows the mixing of one
source into another. The mixer features an assignable crossfader. The
ASSIGN (34, 35) switches allow you to select which channel will play
through each side of the crossfader.
7. ASSIGN (34) switch has five settings (OFF, 1, 2, 3 and 4) and allows you
to direct Channel 1, 2, 3 or 4 through the LEFT side of the crossfader.
ASSIGN (35) switch also has five settings (OFF, 1, 2, 3 and 4) and allows
you to direct Channel 1, 2, 3 or 4 through the RIGHT side of the
crossfader. Placing either ASSIGN switch in the OFF position inactivates
that side of the crossfader.
CROSSFADER SECTION: The CROSSFADER (33) allows the mixing
of one source into another. The left side of the CROSSFADER (33) is
CHANNEL 1 and the right side is CHANNEL 2. The CROSSFADER (33)
in your unit is removable and if the need arises can be easily replaced.
Your Gemini mixer comes with an RG-45 PRO (RAILGLIDE™) Dual-
Rail Crossfader. RAIL GLIDE™ crossfaders have internal dual stainless
steel rails that allow the slider to ride smoothly and accurately from end to
end. Also available is our CF-45 PRO (PROGLIDE™) Dual-Rail
Crossfader. This unique crossfader features, state of the art conductive
plastic technology, for unlimited useage. Another crossfader we have
available is the PSF-45 (PRO SCRATCH™) crossfader with a special
curve designed for scratch mixing. Just purchase one from your Gemini
dealer and follow the instructions:
• Unscrew the FADER PLATE SCREWS (B).
• Do not touch the INSIDE SCREWS (C).
• Carefully lift the fader and unplug the CABLE (D).
• Plug the new fader into CABLE (D) and place it back in the mixer.
• Screw the fader to the mixer with the FADER PLATE SCREWS (B).
8. EQUALIZER: This unit features dual 7 band GRAPHIC EQUALIZERS
(36, 37) that allow you to adjust the sound to fit any room. Activate the
equalizer by pressing EQ BUTTON (38) (EQ LED is illuminated). By
adjusting any of the 7 LEFT (36) equalizer slide controls, you can cut or
boost the tonal characteristics of the sound coming from the LEFT
speaker by ±12 dB. Adjusting any of the 7 RIGHT (37) equalizer slide
controls allows you to cut or boost the tonal characteristics of the sound
coming from the RIGHT speaker by ±12 dB. Deactivate the equalizer by
pressing the EQ BUTTON (38) again (EQ LED is OFF).
9. OUTPUT CONTROL: The level of the AMP OUTPUT (5) is controlled by
the MASTER (39) slide. Activating the MONO (40) button (MONO LED is
illuminated) converts the overall output to mono. The BOOTH (41)
control adjusts the level of the BOOTH OUTPUT (6).
