8. Via the LED level indication of the master channel used, control the level of the input channel with its
g
ain 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 level indication light up, there is an overload of the channel.
9. Repeat the steps for the other connected input channels as described above.
6.2 Level control the microphone channels
1. Set the tone controls of the microphone channels to mid-position.
2
. Switch on the corresponding microphone with the button ON AIR of the channel (LED lights).
3. Use one of the assignment switches (LED lights) to switch the microphone channel to one of the master
channels to monitor the signal via the speakers of a PA system connected: button 1 for master channel
ZONE 1, button 2 for master channel ZONE 2, button 3 for master channel ZONE 3.
4. Advance the master control of the master channel used to approx. 2/3 of its maximum.
5. Speak into the microphone. Via the LED level indication of the microphone channel used, control the
level with the level control of the channel. 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 level indication light up, there is an overload
of the channel. The peak LED above the level control also serves as an aid for controlling the level. It
should not light up or only shortly with signal peaks. If it lights permanently, reduce the level with the
level control.
6. 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 BASS) can be boosted or attenuated (± 12 dB). With the controls in mid-position, the frequency
response is not affected.
7. Repeat the steps for the second connected microphone channel as described above.
6.3 Adjustment of the output channels
The output signal is fed to the adjustable outputs OUT 1 to 3 and to the recording outputs REC without
individual level control.
1. Use the assignment switches (LEDs light) to assign the input channels to the three master channels as
desired: button 1 pressed: input channel switched to ZONE 1, button 2 pressed: input channel switched
to ZONE 2, button 3 pressed: input channel switched to ZONE 3.
2. For mixing several audio sources to one master channel, adjust the desired volume ratio of the audio
sources to one another with the channel faders or level controls of the corresponding input channels.
3. Via its LED level indication, control the level of each master output with the master control. Usually an
optimum level control is obtained if the level indication 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. If the output level is too low for the following
unit, set the level selector switch for the master outputs to »1.5 V«.
4. In each master channel, use the 3-way tone control to attenuate or boost the high frequencies (control
HIGH), the midrange frequencies (control MID), and the low frequencies (control BASS) and readjust the
master level if necessary.
5. The recording signal at the recording outputs REC is taken off ahead of the output controls, i.e. it is not
affected by the master controls OUT 1 to 3.
6.4 Microphone announcements
1. Switch on the corresponding microphone with the button ON AIR of the channel (LED lights) and use
one of the assignment switches (LED lights) to switch the microphone channel to one of the master
channels: button 1 pressed: microphone channel switched to ZONE 1, button 2 pressed: microphone
channel switched to ZONE 2, button 3 pressed: microphone channel switched to ZONE 3.
2. To improve the audibility of an announcement during the current music program activate the talkover
function (press button ON). With the function activated, the levels of the channels 1 to 5 are
automatically attenuated – depending on the controls DB and TIME – when announcements are made
with the microphone. To switch off the talkover function, unlock the button ON (LED off).
3. With the rear selector switch WITH MIC/NO MIC, adjust the level of the micorphone channels at the
recording outputs: »WITH MIC« for full level (basic setting) and »NO MIC« for reduced level.
