Volume control for the signal at the stereo input (MAIN IN LEFT/RIGHT).

Volume control for the signal at the stereo output (MAIN OUT LEFT/RIGHT).

MAIN LINK When the MAIN LINK switch is depressed, the signal at the stereo input (MAIN IN LEFT/RIGHT) is sent to the stereo output (MAIN OUT LEFT/RIGHT). The result is a mix of signals from the stereo output and mixer channels 1 - 6, which are connected as mixer channels (Button 8 in channel depressed).

INPUT LEVEL 6-segment LED level metre for the signal at the stereo input (MAIN IN LEFT/RIGHT). The red CLIP LED of the level metre lights up as soon as the level of the signal at the stereo input is 4 dB below the clipping threshold. Brief flashing of the CLIP LED when peaks occur in the connected signal is not critical. Permanent illumination of the CLIP LED should be avoided by reducing the volume of the source device and/or the volume at the MAIN INPUT LEVEL control.

OUTPUT LEVEL 6-segment LED level metre for the signal at the stereo output (MAIN OUT LEFT/RIGHT). The red CLIP LED of the level metre lights up as soon as the level of the signal at the stereo output reaches the clipping threshold. Brief flashing of the CLIP LED when peaks occur in the connected signal is not critical. Permanent illumina- tion of the CLIP LED should be avoided by reducing the volume of the source device, channels 1 - 6, and/or the volume at the MAIN INPUT LEVEL control.

Channel in SPLITTER mode: Volume control for the signals at the stereo input. The signals are sent to the individual output of the respective channel (OUTPUT CHANNEL 1 - 6). The signal strength also depends on the MAIN INPUT LEVEL volume control. Channel in MIXER mode: Volume control for the signal at the individual input channel 1 - 6. The signal is switched to the stereo output (MAIN OUT LEFT/RIGHT).

Channel in SPLITTER mode: Balance control for the signals at the stereo input. Adjustment of the balance in volume between the left and right input signal (MAIN IN). The two signals are merged into a mono signal that is present at the output of each channel. Channel in MIXER mode: Panorama control for the signal at the individual input channel 1 - 6. Setting of the position in the stereo mix of the MAIN OUT.

Channel in SPLITTER mode: 6-segment LED level meter for the output level of the respective channel

1 - 6. Brief flashing of the red CLIP LED when peaks occur in the connected signal is not critical. Permanent

illumination of the CLIP LED should be avoided by reducing the volume at the MAIN INPUT LEVEL control and or at the LEVEL control in the channel. Channel in MIXER mode: 6-segment LED level meter for the input level of the respective channel 1 - 6. Brief flashing of the red CLIP LED when peaks occur in the connected signal is not critical. Permanent illumination of the CLIP LED should be avoided by reducing the volume of the source device and/or the volume at the LEVEL control in the channel.
