CONNECTIONS

Except for microphones, headphone and master outputs, all connections are cinch. Use good quality cinch-cinch cables to prevent bad audio quality. (example: JB Systems code: 2-0370)

For more information on connections, please refer to the next chapter.

Be sure to turn off the mixer before you make changes to the different connections.

In this manual we talk about "line inputs". This is a global name for inputs with a level between 750mV and 2V. This includes tuners, videos, CD-players, etc.

CONTROLS AND FUNCTIONS

1. DJ MIC INPUT JACK: Combo jack. Accepts either a balanced microphone with an XLR connector or an unbalanced microphone with 1/4 mono jack. This input is mainly used as DJ-microphone. The talk over does not affect the signal level of this input.
2. GAIN LEVEL: Adjusts the input level of the DJ input. Use this control to adjust the level of the DJ microphone on the VU-meter at about 0dB.
3. 3-BAND TONE CONTROL: The frequency of the DJ micro can be controlled over a +/-12dB range.
4. PANPOT CONTROL: Used to place the sound from the DJ micro somewhere in the stereo field. A panpot control does the same for mono signals as a balance control does for stereo signals.
5. DJ MIC VOLUME: Used to adjust the level of the DJ micro.
6. TALKOVER: Use the switch to automatically mute the input channels 1 to 5 while you are talking through the DJ microphone. You can adjust the amount of muted on input channels 1 to 5. The more you turn the talkover level to the right, the more these channels are muted while talking through the DJ Micro(1).
7. PFL SELECTOR: Used to select the source (CH-1 to CH-5) to be monitored via the headphones output. Pressing multiple Cue Buttons makes it possible to derive a mixed sound from the selected sources.
8. CHANNEL FADER: Used to set the level of each channel separately.

9. CHANNEL VU METER: Each channel has its own LED VU-meter so you can adjust the gain level (11) very quickly. Make sure the levels do not exceed 0dB (or 100% ). The audio risks to be distorted when the signal level comes in the red zone of the VU-meter.

10. INPUT SOURCE SELECTOR: Used to select the correct input on each channel: Phono, line, aux or mic. On some channels there are additional input selectors on the back.

Hint: Line, Aux, CD, Tuner, etc... are different names for inputs with almost the same signal levels.

1. GAIN LEVEL: Adjusts the input level on each channel. Use this control to adjust the level on the VU-meter at about 0dB.

12.3-BAND TONE CONTROLS: The frequency of each channel can be controlled separately over a range from -26dB to +12dB. In the center position the tone control is flat. (switched off)

1. BEAT COUNTER DISPLAY: Shows the number of beat per minute (BPM) of the music on the channel selected with the crossfader assign selector (17). To have a reliable result on the display the music must have a clear and steady beat.

14.FADER START ON/OFF SWITCH: When you have a compatible CD-player connected to the fader control connectors, you can control its start/stop (re-cue) functions with the cross fader. With this switch you can turn the fader start control on and off.

1. BEAT OFFSET INDICATOR: This indicator has several colored LEDs which indicate if the beat on both beat counters are well synchronized. When both beat counters are completely out of sync, the red LEDs will be lit. You will have to adapt the speed of the connected audio sources so the beats will be nicely synchronized. When the synchronization becomes better the yellow LEDs will turn on. Finally, when both beats are in perfect sync, the green led in the center turns on. Now you can mix the beat of 2 audio sources together.

2. CROSSFADER: With this fader you can mix over between the channels you selected with the crossfader assign selectors (17). The crossfader only works when you move the selected channel faders (8) to the desired level! The crossfader also integrates the optical fader starts. See the next chapter for more information on this issue.

3. CROSSFADER ASSIGN: Selects the input channels to be used with the crossfader (16) and beat counters (13). When set to "0" the crossfader is switched off.

4. MASTER1 LEVEL: Used to adjust the level of the balanced Master1 output.

19.BALANCE MASTER1: used to adjust the balance between left and right output on Master1.

1. MASTER2 LEVEL: Used to adjust the level of the unbalanced Master2 output.

21.BALANCE MASTER2: used to adjust the balance between left and right output on Master2.

1. MONO/STEREO SWITCH: used to switch both masters in mono or stereo mode.

2. MASTER1 VU METERS: Monitors the output level of master1. Make sure the levels do not exceed 0dB (or 100% ). The audio risks to be distorted when the signal level comes in the red zone of the VU-meter.

3. CUE MIX: With this fader you can mix the master output and any of the input channels through the headphone output (26):

4. Put the fader in the extreme left position to monitor a selected PFL signal (7).

5. Put the fader in the extreme right position to hear the master output.
6. Put the fader in any other position to hear a mix of the two signals.

This option makes it possible to check your mix before you put it on the master output.

25.CUE LEVEL: Used to control the output level of the headphone output.
26. HEADPHONE jack: You can monitor all inputs/outputs when you connect any modern stereo headphone to this 6.3mm jack.
27. POWER switch: Used to turn the power of the mixer on and off. The blue led is lit when the mixer is turned on.

REAR PANEL

1. MAINS CABLE: connect this cable to a 230V/50Hz mains outlet. Before use, inspect the cable to be sure it's not damaged!
   29.FADER CONTROL: When connected to these inputs, compatible CD-players can be controlled by the fader starts of this mixer.
   30.MASTER1 BALANCED OUTPUT: The XLR-connectors can be used to connect this mixer to any balanced amplifier input, using special balanced signal cables.
2. MASTER UNBALANCED OUTPUTS: The "mast.1" output has the same output signal as the balanced master output(30) but unbalanced. The "mast.2" output carries the same signal but can be controlled independently by the master2 level/balance (20/21). Use the outputs to connect unbalanced amplifiers.
3. RECORD OUTPUT: Carries the same signal as the master outputs but is not influenced by the master level, balance and mono/stereo controls. Used to connect analog recording equipment.
4. INPUT CHANNEL 5: used to connect two different line level audio signals. The input source selector (10) on the front determines which input will be active.
5. INPUT CHANNEL 4: used to connect a turntable and/or a line level audio signal. The input source selector (10) on the front determines which input will be active.
   35.GROUND (GND) CONNECTION: Many Turntables have a GND-connection. It is preferable to connect this signal ground to the GND-connector. If your turntable does not have a ground wire, you don't have to use this connector.
6. INPUT CHANNEL 3: used to connect a turntable and/or a line level audio signal. The input source selector (10) on the front determines which input will be active.
7. INPUT CHANNEL 2: used to connect two different line level audio signals. Refer to switch (39) to change one line input to microphone level. The input source selector (10) on the front determines which input will be active.
   38.MIC2 INPUT: Used to connect an unbalanced microphone to channel 2. Refer to switch (39) to change the CD1 input to mic2.
   39.MIC2/CD1 SWITCH: This switch makes it possible to switch between the CD1 input (37) and the mic2 input (38) on channel2.
   40.LINE INPUT CHANNEL1: used to connect a line level audio signal to channel1.
   41.MIC1 INPUT CHANNEL1: used to connect a microphone to channel1.

CROSSFADER STARTS

The crossfader integrates the optical fader start switches. These fader starts are compatible with all current JB Systems CD-players. This is how it works:

A. CROSSFADER IN LEFT POSITION:

CD-player connected to fader start connector 1 is playing, the other CD-player is paused.

B. CROSSFADER MOVES TO THE RIGHT: CD-player connected to fader start connector 1 stops playing, returns to its previously programmed cue point and waits in pause. The other CD-player starts playing from its previously programmed cue point.

C. CROSSFADER IN RIGHT POSITION:

CD-player connected to fader start connector 2 is playing, the other CD-player is paused.

D. CROSSFADER MOVES TO THE LEFT: CD-player connected to fader start connector 2 stops playing, returns to its previously programmed cue point and waits in pause. The other CD-player starts playing from its previously programmed cue point.

Important: Both fader start switches must be in "ON" position!
