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(ORD). The recording level is
independent of the position of the master fader and the output control ZONE. With an audio interface
such as the
OMNITRONIC DDI 4x4
you can also digitize the analog output signal of the
EMX-1
and transfer it to a computer with USB 1.1 or 2.0 connection.
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-3
and the mains plug to a mains socket.
Use the unit only with the supplied 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, set the master fader to zero and the output control ZONE to 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
1. First set all gain controls, equalizer controls and the crossfader to mid-position. Set the two assignment
selectors X-FADER ASSIGN to the position "OFF".
2. Use the input selector to select the input to which the audio source is connected.
3. Feed an audio signal (test signal or music piece) to the channel and advance the channel fader to
approx. 2/3 of its maximum. Set all other channel faders to zero.
4. To monitor the signal via the speaker of a PA system connected, advance the master fader or the output
control ZONE to approx. 2/3 of its maximum. The signal can also be monitored via headphones (please
refer to section
6.6).
5. Via the LED output meter, control the level of the channel with the corresponding 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 and the level of the input signal
must be reduced.
6. Repeat the steps for the other connected input channels as described above.
6.2 Basic adjustment of the output channels
The output signal is fed to the adjustable outputs MASTER and ZONE and to the recording output
REC(ORD) without individual level control.
1. The LED output meter indicates the level of the signal at the master outputs. Via the output meter, adjust
the desired level with the master fader. Usually an optimum level control is obtained if the output meter
shows values in the 0 dB range at average volume. However, if the output level at the master outputs is
too high for the following unit, the master signal must be controlled to a corresponding lower level.
2. Adjust the sound for the master signal with the tone controls. 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. With the controls in mid-position, the frequency response is
not affected. Sound adjustments affect the level. Check the channel level with the output meter and
readjust it, if required.
3. Adjust the desired signal level for the output ZONE with the control ZONE.
4. The recording signal at the output REC(ORD) is taken off ahead of the output controls, i.e. it is not
affected by the master fader or the output control ZONE.
