Connections1. Before plugging in the power cord, make sure that the VOLTAGE SELECTOR

(43) switch is set to the correct voltage.

NONONONONOTETETETETE: This product is double insulated and not intended to begrounded.

2. Make sure that the POWER (1) switch is in the off position. The POWER LED (2)will be off.

3. The BPM-1000 is supplied with 2 sets of amp output jacks. The BALANCEDOUTPUT AMP (56) jacks are used to connect to your main amplifier usingstandard XLR cables. We recommend using the balanced amp outputs if thecables to your amp are 25 feet or more. Balanced outputs have three separateconductors, two of which are signal (positive and negative) and one shield(ground). Pin 1 is ground (shield). Pin 2 is signal hot (positive). Pin 3 is signalcold (negative). The OUTPUT AMP (44) jacks are unbalanced and used toconnect to your main amplifier. The OUTPUT BOOTH (45) jacks allow you tohook up an additional amplifier.

4. The MIC 1 (3) input (found on the front panel) accepts a 1/4" or XLR connector.The MIC 2 (58) input and the MIC 3 (57) input (found on the rear panel) accept1/4" connectors. All accept balanced and unbalanced microphones.

5. On the rear panel are 1 stereo PHONO/LINE (53) input, 2 stereo PHONO (49,51) inputs, and 5 stereo LINE (46, 47, 48, 50, 52) inputs. The PHONO/LINESWITCH (55) enables you to set the (53) input to Phono or Line. The phonoinputs will accept only turntables with a magnetic cartridge. A GROUND SCREW(54) for you to ground your turntables is located on the rear panel. The stereo lineinputs 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 (13)jack.

Using the Ground Lift SwitchDepending on your system configuration, sometimes applying the ground will createa quieter signal path. Sometimes lifting the ground can eliminate ground loops andhum to create a quieter signal path.

1. With the mixer on, listen to the system in idle mode (no signal present) with theground applied (the GROUND LIFT SWITCH (59) in the bottom position).

2. Then turn the power off before moving the GROUND LIFT SWITCH (59). Liftthe ground by moving the GROUND LIFT SWITCH to the top position, turn thepower back on and listen to determine which position will provide a signal devoidof background noise and hum. Keep the GROUND LIFT SWITCH in the groundposition if the noise level remains the same in either position.

CAUTION: DO NOT TERMINATE THE AC GROUND ON THE POWER MIXER INANY WAY. TERMINATION OF THE AC GROUND CAN BE HAZARDOUS.

Operation1. 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.

2. CHANNEL 1: The GAIN (14), HIGH (15), MID (16), and LOW (17) controls allowyou to fully adjust the selected source. Switch # (18) allows you to select thePHONO 1/LINE 1 (53) or the LINE 2 (52) input. The CHANNEL SLIDE (19)controls the input level of this channel.

3. CHANNEL 2: The GAIN (14), HIGH (15), MID (16), and LOW (17) controls allowyou to fully adjust the selected source. Switch # (21) allows you to select thePHONO 2 (51) or the LINE 3 (50) input. The CHANNEL SLIDE (22) controls theinput level of this channel.

4. CHANNEL 3: The GAIN (14), HIGH (15), MID (16), and LOW (17) controls allowyou to fully adjust the selected source. Switch # (23) allows you to select thePHONO 3 (49) or the LINE 4 (48) input. The CHANNEL SLIDE (24) controls theinput level of this channel.

5. CHANNEL 4: The GAIN (14), HIGH (15), MID (16), and LOW (17) controls allowyou to fully adjust the selected source. Switch # (25) allows you to select theLINE 5 (47), LINE 6 (46) or the MIC 3 (57) input. The CHANNEL SLIDE (26)controls the input level of this channel.

NONONONONOTETETETETE: There is Low, Mid and High equalization for each channelwith an extremely wide range of adjustment providing a smoothermix.

SUGGESTION: You can use the Cut Features on each channel to remove Low,Mid and/or High to create special effects.

6. CROSSFADER SECTION: The CROSSFADER (27) allows the mixing of onesource into another. The BPM-1000 features an assignable crossfader. TheASSIGN (28, 31) switches allow you to select which channel will play througheach side of the crossfader. The ASSIGN (28) switch has 4 settings (1, 2, 3 or 4)and allows you to select channel 1, 2, 3 or 4 to play through the left side of thecrossfader. The ASSIGN (31) switch has 4 settings (1, 2, 3 or 4) and allows you toselect channel 1, 2, 3 or 4 to play through the right side of the crossfader. Thereare two OFF (29, 32) buttons for the crossfader. When the OFF (29) button ispressed, the left side of the crossfader will be inactive and the OFF LED (30) willlight. When the OFF (32) button is pressed, the right side of the crossfader will beinactive and the OFF LED (33) will light. Using the OFF button, be sure todeactivate the crossfader before changing the ASSIGN setting. This will avoid anyclick or popping sound in your signal while you are changing the assign setting.The CROSSFADER (27) in your unit is removable and if the need arises can beeasily 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 travelfrom side to side. Part # RF-30 is available with a 30 mm travel distance. Alsoavailable is the PSF-45 with a special curve designed for scratch mixing. Justpurchase one of these crossfader units from your Gemini dealer and follow theseinstructions:

1. Unscrew the outside FADER PLATE SCREWS (B). Do not touchthe 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.

7. BPM DISPLAY: There are BPM DISPLAYS (34, 35) for the two channelsassigned to each side of the CROSSFADER (27). They update approximatelyevery beat and digitally display the Beats Per Minute allowing you to match thebeats visually. BPM DISPLAY (34) reflects the Beats Per Minute of the channelassigned to the left side of the CROSSFADER, and BPM DISPLAY (35) reflectsthe Beats Per Minute of the channel assigned to the right side of theCROSSFADER.

NONONONONOTETETETETE: A [- -] reading will appear on the BPM DISPLAY if the trackhas unclear beats. The [- -] reading will also appear if there is nosignal present.

8. The BEAT OFFSET INDICATORS (36) light when the tracks of the two channelsassigned to the crossfader are within 11 BPMs of each other and display howaligned the beats of the two channels are. When the RED LEDs light, the beatsare not aligned. When the YELLOW LEDs light, the beats are almost aligned.When the GREEN LED lights, the beats are aligned perfectly.

NONONONONOTETETETETE: If the diffence between the two channel’s beats exceed 11BPM, the BEAT OFFSET INDICATORS will not light.

SUGGESTION: You can use the BPM DISPLAYS to determine which trackshave similar or the same Beats Per Minute. When mixing two tracks withsimilar Beats Per Minute, you can use one source’s pitch control to align theBeats Per Minute with the other source’s BPM. The BPM DISPLAYS and theBEAT OFFSET INDICATORS update every beat and will reflect the change inBPM and indicate when the beats are aligned.

NONONONONOTETETETETE: Beat mixing is a skill that requires practice. Not every trackhas a strong beat, and beat mixing works best with tracks withclear and strong beats.

9. OUTPUT CONTROL SECTION: The level of the AMP OUT (44, 56) is controlledby the MASTER (41) slide and the BALANCE CONTROL (40). The BOOTH (42)control adjusts the level of the BOOTH OUTPUT (45). HINT: The booth OUTPUTis used by some DJs to run monitor speakers in their DJ booth. You can also useit as a second ZONE or AMP output. Activating the MONO (39) button (the monoLED will light) makes the master output mono.

10. TALKOVER SECTION: The purpose of the talkover section is to allow theprogram playing to be muted so that the mic can be heard above the music. TheMIC/TALKOVER (9) switch controls MIC 1 and MIC 2 and has three settings.When the MIC/TALKOVER (9) switch is in the left position, MIC 1 and MIC 2 andtalkover are off. When the MIC/TALKOVER (9) switch is in the center position

MIC 1 and MIC 2 are on, the MIC INDICATOR (8) will glow, but talkover is off.When the MIC/TALKOVER (9) switch is in the right position, MIC 1 and MIC 2and talkover will be on and the volume of all sources except the Mic inputs arelowered by 16 dB. The TREBLE (4) and BASS (5) controls allow you to fullyadjust the tone of MIC 1 and MIC 2. MIC 1 LEVEL (7) controls the level of MIC 1.The MIC 2 LEVEL (6) controls the level of MIC 2.

11. CUE SECTION: By connecting a set of headphones to the HEADPHONE (13)jack, you can monitor any or all of the channels. Press the CUE ASSIGN (20)buttons for channels 1 - 4 to select the channel or channels to be monitored andtheir respective LED indicators will glow. Use the CUE LEVEL (10) control toadjust the cue volume without effecting the overall mix. By rotating the CUE PGMPAN (12) control to the left you will be able to monitor the assigned cue signal.Rotating to the right will monitor the PGM (program) output. Use the CUE SPLIT(11) button to split the signals from cue and program so that cue will be heard inone earphone and program will be heard in the other earphone.

12. DISPLAYS: The PEAK HOLD LED METER (37) indicates the MASTEROUTPUT (44, 56) left and right channel levels. The individual channels eachhave their own PREFADER INPUT LEVEL PEAK HOLD LED METERS (38)which reflect the GAIN (14), HIGH (15), MID (16), and LOW (17) rotary controladjustments. The CHANNNEL SLIDES (19, 22, 24, 26) will not effect thePREFADER INPUT LEVEL PEAK HOLD LED METERS (38).
