PHONO/LINE SWITCH (47) enables you to set the (46) input to Phono or Line. Attach phono ground line to the GROUND THUMB SCREW (49). Congratulations on your purchase of the Gemini PMX -1400 Mixer. This state-of-the-art unit is backed by a three year warranty, excluding crossfader and channel slides. Prior to use, we suggest that you carefully read all the instructions. ® 7. Headphones may be plugged into the front panel mounted HEADPHONE (32) jack. 8. The PMX-1400 comes with a front panel BNC LIGHT (25) jack for use with a (not provided) gooseneck light. FEATURES: • • • • • • • 4 Stereo Channels Talkover State-of-the-Art Cue Section Dual 7 Band Graphic Equalizers Booth and Record outputs Balanced and Unbalanced Master Outputs 3 Phono/Line Convertible, 5 Line, and 2 Mic Inputs 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 (50) in the LEFT position. CAUTIONS: 1. All operating instructions should be carefully read before using this equipment. 2. Turn the power OFF before moving the GROUND LIFT SWITCH (50). “Lift” the ground by moving the GROUND LIFT SWITCH 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 in the “ground” position if the noise level remains the same in either position. 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 USA: If you experience problems with this unit, please call 1 (732) 969-9000 for Gemini Customer Service. Do not attempt to return this equipment to your dealer. CAUTION: DO NOT TERMINATE THE AC GROUND ON THE MIXER. CABLE. TERMINATION OF THE AC GROUND CAN BE HAZARDOUS! 3. Do not expose this unit to direct sunlight or to a heat source such as a radiator or stove. OPERATION: 4. This unit should be cleaned only with a damp cloth. Avoid solvents or other cleaning detergents. 1. POWER: Once you have made all the equipment connections to your mixer, press the POWER SWITCH (26). The power will turn on and the POWER LED (27) will glow RED. 5. When moving this equipment, it should be placed in its original carton and packaging. This will reduce the risk of damage during transit. 2. CHANNEL 1: Switch (9) allows you to select PHONO 1/LINE 1 (46) or the LINE 2 (45) input. CHANNEL SLIDE (10) controls the input level of this channel. 6. DO NOT EXPOSE THIS UNIT TO RAIN OR MOISTURE. 3. CHANNEL 2: Switch (11) allows you to select PHONO 2/LINE 3 (43) or the LINE 4 (42) input. CHANNEL SLIDE (12) controls the input level of this channel. 7. DO NOT USE SPRAY CLEANER OR LUBRICANT ON CONTROLS OR SWITCHES. 4. CHANNEL 3: Switch (13) allows you to select PHONO 3/LINE 5 (40) or the LINE 6 (39) input. CHANNEL SLIDE (14) controls the input level of this channel. CONNECTIONS: 5. CHANNEL 4: Switch (15) allows you to select either the LINE 7 (38) or LINE 8 (37) input. CHANNEL SLIDE (16) controls the input level of this channel. 1. Before plugging the power cord in, make sure that the VOLTAGE SELECTOR (33) switch is set to the correct voltage. NOTE: THIS PRODUCT IS DOUBLE INSULATED AND IS NOT INTENDED TO BE GROUNDED. 6. CROSSFADER: The CROSSFADER (18) allows the mixing of one source into another. The PMX-1400 features an assignable crossfader. The ASSIGN (17, 19) switches allow you to select which channel will play through each side of the crossfader. 2. Make sure that the POWER (26) switch is in the OFF position. The POWER LED (27) display will be off. 7. ASSIGN (17) 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 switch (19) 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. The CROSSFADER in your unit is removable and, should the need arise, can be easily replaced. Replacement crossfaders are available in three models: the RG-45 PRO (RAIL GLIDE™) DualRail Crossfader; as well as RF-45, which has a 45mm travel from side-to-side; and the PSF-45, which features a special “curve” designed for scratch mixing. Your Gemini mixer is equipped 3. The PMX-1400 is supplied with four sets of output jacks: The MAIN OUTPUT (34) jacks connect to the main amplifier. The BALANCED MASTER OUTPUT (99) 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 REC OUTPUT (36) jacks can be used to connect the mixer to the record input of your recording unit, thus enabling you to record your mix. The BOOTH OUTPUT (35) jacks allow the connection of an additional amplifier. 4. The MIC 1 input (located on the front panel) accepts an XLR connector. The MIC 2 (48) input (on the rear panel) accepts 1/4" connectors. All accept balanced and unbalanced microphones. with an RG-45 PRO (RAIL GLIDE™) 45MM DUAL-RAIL CROSSFADER featuring internal dual stainless steel rails that allow the slider to ride smoothly and accurately from end-to-end. 5. On the rear panel are three stereo PHONO/LINE (40, 43, 46) inputs and five stereo LINE (37, 38, 39, 42, 45) inputs: PHONO/LINE SWITCH (41) enables you to set the (40) input to Phono or Line.

NOTE: REC OUTPUT HAS NO LEVEL CONTROL. LEVEL IS CONTROLLED WITH THE CHANNEL SLIDES OF THE SELECTED CHANNEL(S). TONE IS CONTROLLED VIA THE EQUALIZERS. 10.TALKOVER: The purpose of the talkover is to allow the program playing to be muted so that the mic may be heard above the music. The MIC/TALKOVER SWITCH (7) controls MIC 1 and MIC 2 and has three settings. • When MIC/TALKOVER (7) is in the BOTTOM position, MIC 1, MIC 2 and TALKOVER are all OFF. • When MIC/TALKOVER (7) is in the CENTER position, MIC 1 and MIC 2 are ON. MIC INDICATOR (6) glows/TALKOVER is OFF. • When MIC/TALKOVER SWITCH (7) is in the TOP position, MIC 1, MIC 2 and TALKOVER are ON and the volume of all sources except MIC inputs is lowered by 16 dB. 11. TREBLE (2) and BASS (3) controls allow you to adjust the tone of MIC 1 and MIC 2. MIC 1 LEVEL (5) controls the level of MIC 1 while MIC 2 LEVEL (4) controls the level of MIC 2. 12.CUE: By connecting a set of headphones to the HEADPHONE (32) jack, you can monitor any or all channels. Press CUE ASSIGN (20) buttons for Channels 1 through 4 and select the Channel(s) to be monitored. The respective LED indicators will glow. Use the CUE LEVEL (31) control to adjust the cue volume without changing the overall mix. By moving the CUE PGM PAN (30) control to the LEFT you will be able to monitor the assigned cue signal. Moving the control to the RIGHT allows you to monitor PGM (program) output.
