3 Applications

The mixer MPX-210BPM with four stereo channels, two mono microphone channels, and integrated beat counter function is suitable for any desired private or professional DJ applications.

The unit can be placed as a table top unit as well as being installed into a console. It is suitable for rack mounting (482 mm/19") as well. For rack mounting a height of 4 rack spaces (1 rack space = 44.45 mm) is necessary.

4 Connection of the Unit

Prior to the connection of units or changing of existing connections, switch off the mixer.

1) Connect the stereo audio sources to the corresponding phono input jacks of channels CH 1 to CH 4 (white jack L = left channel; red jack R = right channel):

• units with line level output (e.g. mindisk recorder, CD player, cassette recorder) to the jacks CD and LINE (30);
• turntables with magnetic system to the PHONO jacks (31).

The clamping screw GND (33) can be used as common grounding point: connect the grounding connection of the turntable to the clamping screw.

2) Connect mono microphones to the XLR jacks (7) on the front plate or to the 6.3mm jacks (32) on the rear side of the unit.
3) Connect the input of the amplifier to the master output AMP (29).
4) If a monitor system is present, connect the amplifier of the monitor system to the BOOTH output (28).
5) For audio recordings, connect the recording unit to the record output REC (27). The recording level is independent of the position of the master control (21).
6) For an optimum console illumination a gooseneck lamp (12 V/5 W max.) can be connected to the BNC jack LAMP (4), e.g. the lamp GNL-205 of the "img Stage Line" range. The lamp is switched on and off with the mixer.
7) Via stereo headphones the pre fader level of the input channels CH 1 to CH 4 as well as the current music programme ahead of the master control (21) can be monitored (see chapter 5.6). Connect the headphones (impedance ≥ 2× 8 ) to the jack (24).
8) Finally connect the plug of the mains cable (26) to a mains socket (230V / - 50Hz)

5 Operation

Prior to switching on, the output controls MASTER (21) and BOOTH (22) should be set to minimum to avoid strong inrush noise. Then switch on the mixer with the POWER switch (5). The red LED above the switch lights up to indicate that the unit is ready for operation. Then switch on the connected units.

5.1 Basic settings

5.1.1 Basic setting of channels CH1 to CH4

For an optimum level adjustment of the audio sources connected to the input channels CH 1 to CH 4, turn all gain controls (6) and equalizer controls (1) to mid-position first, and set the ASSIGN switches (13 and 19) to "0" (crossfading function switched off).

1) Select the connected signal sources with the selector buttons (20).

Button not pressed (▲):

the PHONO input (for channels CH1 and CH3) or the CD input (for channels CH2 and CH4) is selected.

Button pressed () -LED above the button lights up: the LINE input of the channel is selected.

2) With the master control (21) the total level of all connected audio sources is adjusted. Set the master control to approx. 2/3 of its maximum position, e.g. to position 7.
3) The selector button (3) must not be pressed: with this button position the VU meter (2) shows the stereo output level which is present at the master output AMP (29).
4) To control a channel, set the faders (15) of the remaining channels to minimum and feed the audio signals (test signals or music pieces) to the respective input channel.

5) By means of the VU meter control the level of the channel with the fader. The optimum level is obtained if the 0 dB LEDs of the VU meter shortly light up with music peaks. In case of overload the red LEDs light up.

After the level adjustment the fader should be set to approx. 2/3 of its maximum position so that there is sufficient control range for fading in and out.

6) If the fader is slipped up very much or only very little, the level must be matched by adjusting the input amplification: turn back or turn up the gain control (6) of the channel correspondingly.

The input amplification can be adjusted in an optimum way by the display of the pre fader level. For this purpose press the button (3) to switch the VU meter to the display mode "PFL", slide the MIX control (23) to the left stop to position "PFL", and press the PFL button (12) of the channel: the VU meter now shows the signal level of the channel ahead of the channel fader.

7) Release button (3) to switch the VU meter to the display mode "MASTER" again, and adjust the desired sound with the equalizer controls (1) of the channel - a 3-way equalizer each for the channel group CH1/CH2 and the channel group CH3/CH4: with the three controls the high range (HIGH controls), the midrange (MID controls), and the bass range (BASS controls) can be boosted (max. 15 dB) or attenuated to a large extent (max. 30 dB). If the controls are in mid-position, there is no influence on the frequency response.

Note: Sound adjustments influence the levels. Therefore, after a sound adjustment, check the channel level by means of the level display and correct it, if necessary.

8) Make the level and sound adjustments for the remaining connected input channels as described above.

5.1.2 Basic setting of the microphone channels

To switch on a microphone channel, press the ON AIR button (11) of the channel. The LED next to the button lights up as indication. Set the faders (15) of the input channels CH1 to CH4 to minimum, and adjust the optimal level with the GAIN control (8) of the channel by means of the VU meter (2). Correct the sound for the microphone (max. ± 15dB ) with the equalizer controls (9) - HIGH for the high range, MID for the mid-range, BASS for the bass range.

Make the level and sound adjustments for the second microphone channel in the same way.

5.2 Crossfading function

1)With the two ASSIGN switches select the two channels of the input channels CH1-CH4 to be cross-faded:

With the left ASSIGN switch (13) select the channel to be faded in if the crossfader (16) is slid to the left.

With the right ASSIGN switch (19) select the channel to be faded in if the crossfader is slid to the right.

2) Set the faders (15) of the channels not used to minimum and control the two selected channels with their faders in an optimum way (see chapter 5.1.1).

3) With the crossfader, it is now possible to fade between the two selected channels.
If both channels are to be fed to the outputs at the same time, set the crossfader to the mid-position.
4) With the master control (21) adjust the desired total level which is available at the master output (29). In case of overload [red LEDs of the VU meter (2) light up] reduce the master level.

5.3 Beat counter

The two beat counters of the mixer measure the beats per minute (BPM) for the two channels selected with the ASSIGN switches for the crossfading function. The measured BPM are shown via two displays.

Note: the beat counters only evaluate bass beats which occur four times in succession at approx. the same distance (4 / 4 beat). Music pieces which do not show any clear bass drum line in the 4 / 4 rhythm are not recognized by the beat counters and displayed with wrong values.

5.3.1 BPM displays

Most CD players for disco applications are provided with operating elements to change the speed of the beat (pitch controls). For matching the pitch of one music piece to that of the other via the pitch control when crossfading between the connected audio sources (e.g. two CD players), the two BPM displays of the mixer serve as optical aid.

The left BPM display (14) shows the beats for the channel selected with the left ASSIGN switch (13) and the right BPM display (18) the beats for the channel selected with the right ASSIGN switch (19). If no music piece is playing on the selected channel or if the respective ASSIGN switch is set to "0", the display is [- - -].

The display range is between approx. 90 BPM and 170 BPM. If the BPM of a title are lower, the display is [- - - ] or a wrong value. Higher BPM values are displayed in a divided way (e.g. display 90 BPM in case of an actual value of 180 BPM).

5.3.2 Beat Offset display

To obtain a smooth transition between the titles when crossfading, the beats of both titles have to be synchronized, i.e. they must be exactly the same. Via corresponding operating elements on the CD player the pitch of one title can be matched so that it is synchronized with the second title.

When synchronizing the beats of the two music titles to be crossfaded, the LED indication BEAT OFF-SET (17) serves as optical control:

Lighting up of a red LED:

the two titles are not synchronized

Lighting up of a yellow LED:

the two titles are almost synchronized

Lighting up of the green LED:

the two titles are synchronized

Note: If the BPM of the two titles are far away from each other, the beat offset display does not respond.

5.4 Mixing of the audio sources

1) To mix the connected audio sources, switch off the crossfading function. For this purpose, set the ASSIGN switches (13 and 19) to position "0".
2) Turn up the master control (21) so much that the mixing relation of the audio sources can be adjusted in an optimum way.
3) With the level controls of the input channels adjust the desired volume relation of the audio sources with each other. If a channel is not used, its level control should be set to minimum.
4) By means of the VU meter (2) adjust with the master control the desired total level which is available at the master output (29).

The optimum level is obtained if the 0 dB range of the VU meter shortly lights up with music peaks. In case of overload (red LEDs light up), reduce the output level with the master control and/or the level controls of the input channels.

5.5 Talkover function

The talkover function serves for better intelligibility of microphone announcements during the music programme. To activate the func tion for a microphone channel, press the AUTO TALK button (10) of the channel: if the button is pressed (LED next to the button lights up), the levels of the channels CH 1 to CH 4 are automatically attenuated by 15dB during microphone announcements. To switch off the function, release the button again.

5.6 Pre fader listening (PFL) of the channels via headphones

Via the pre fader listening function each of the input channels CH1 to CH4 can be monitored via headphones connected to the jack (24), even if the corresponding channel fader (15) is set to minimum. Thus, e.g. the desired title on a CD can be selected or the right moment for fading in an audio source can be timed.

Alternatively it is also possible to monitor the music programme currently playing ahead of the master control (21).

1) To monitor an input channel ahead of the channel fader, press the PFL button (12) of the channel (LED above the button lights up) and slide the MIX control (23) to the extreme left position ("PFL").
To monitor the current music programme ahead of the master control, slide the MIX control to the extreme right position ("PGM").
2) To switch the VU meter (2) to the headphone output, press the button (3). Then the VU meter shows the signal selected with the MIX control.
3) With the level control (25) adjust the desired headphone volume.

CAUTION: Do not adjust the headphones to a high volume. Permanent high volumes may damage a person's hearing! The human ear gets accustomed to high volumes which do not seem to be that high after some time. Therefore, do not further increase a high volume after getting used to it.

5.7 Monitoring of the music programme via a monitor system

The music programme currently playing can be monitored ahead of the master control (21) via a monitor system connected to the BOOTH jacks (28). Adjust the level for the monitor system with the BOOTH control (22).
