5. INSTALLATION
5.1 Rack installation
Install the unit on a plane surface or in your rack. For 19" (483 mm) rack installation, 4 units are required.
When mounting the unit into the rack, please make sure that there is enough space around the device so
that the heated air can be passed on. Steady overheating will damage your device. You can fix the unit with
four screws M6 in the rack.
5.2 Connections
S
witch off the mixer prior to connecting any units or to changing any existing connections.
1. Connect the stereo audio sources to the corresponding RCA jacks of channels 1-5 (white jack = LEFT;
red jack = RIGHT):
- Connect units with line level output (e. g. CD/MP3 player) to the jacks LINE
- Connect turntables with magnetic system to the jacks PHONO. If your turntable is equipped with a
separate ground lead, connect it to the clamping screw GND.
2. You can connect up to three microphones: a DJ microphone via a XLR plug or 6.3 mm plug to the DJ
microphone channel DJ MIC on the front panel and two further microphones via 6.3 mm plug to the
microphone channels MIC 2 and MIC 3 on the rear panel.
3. Connect the amplifier(s) to the balanced XLR master output and/or to the unbalanced RCA master
output.
4. If a monitoring system is available, connect the amplifier of the monitoring system to the stereo output
ZONE.
5. For sound recordings, connect the recording unit to the output REC. The recording level is independent
of the position of the output controls ZONE VOLUME and MASTER VOLUME.
6. The input channels can be monitored via stereo headphones. Connect the headphones to the 6.3 mm
jack on the front panel.
7. Connect the power supply unit to the AC input of the EMX-5 and the mains plug to a mains socket.
Use the unit only with the supplied OMNITRONIC power unit. Always disconnect the mains connector
when you wish to change connections, move the unit to a different place or if it is not used for a longer
period.
6. OPERATION
Prior to switching on, turn the output controls ZONE VOLUME and MASTER VOLUME to position
"MINIMUM" to avoid damage to the hearing by a volume which is too high when switching on. Switch on the
unit with the power switch. The power indicator on the front panel lights up. Switch on the connected units.
After operation, switch off the unit with the power switch.
6.1 Basic adjustment of the input channels
First set all gain controls, equalizer controls, the balance control and the crossfader to mid-position.
1. Use the input selector to select the input to which the audio source is connected.
2. Use the assignment selector to assign the channel to the crossfader or set the selector to "OFF".
3. Feed an audio signal (test signal or music piece) to the channel. Switch off the units which are to play on
the other channels or set them to pause.
4. Advance the channel fader to approx. 2/3 of its maximum.
5. To monitor the signal via the speaker of a PA system connected, advance the corresponding output
control MASTER VOLUME or ZONE VOLUME. The signal can also be monitored via headphones
(Please refer to section 6.6).
6. Via the LED output meter, control the level of the respective channel with the gain control. An optimum
level control is obtained if level values in the 0 dB range are shown at average volume. If the red LEDs of
the output meter light up, there is an overload of the channel.
7. Adjust the desired sound with the tone controls of the channel. By adjusting the three tone controls, the
high frequencies (control HIGH), the midrange frequencies (control MID), and the low frequencies
(control LOW) can be boosted or attenuated (± 12 dB). With the controls in mid-position, the frequency
response is not affected. Note: Sound adjustments affect the level. Therefore, after adjusting the sound,
check the channel level with the output meter and readjust it, if required.
