INITIAL OPERATION

NOTE: If the input signal is not present at the master outputs, check the following:

Are the master controls (10) open?

Has the corresponding MIC/LINE input been assigned to one or both output channels? Please mind and compare your actual setting and the selected configuration!

Is ducking control active (see ducking indicators (9)) and does this maybe affect your input signal?

5.2.2 Level Adjustment for AUX-inputs

The four AUX-inputs are provided via two unbalanced RCA-type sockets each, which lets you connect either one stereo signal source (e.g. CD-Player) or two monaural signal sources per input channel. For optimally matching the signal source to the channel input, please proceed as follows:

Set the corresponding channel control (7) on the front panel of the appliance to its counterclockwise margin.

Now, connect the desired audio signal source using common RCA-type cables.

When now playing the signal source with the highest signal level (e.g. loudest passage in a musical piece), the SIGNAL-LED has to light and/or blink in the rhythm of the music. The AUX-inputs are factory pre-set to a nominal sensitivity of +4 dBu, which, in combination with the channel control, is suitable for most AUX-signal sources. In case you want to connect an extremely low-output AUX-signal source, it may happen that the green signal-LED does not light up. Additionally it is possible that you are not able to gain the required volume level using the channel control. In these cases setting the AUX-input’s nominal sensitivity to -6 dBu (via internal bridges) is recommended. This measure will increase the input’s sensitivity by 10 dB. For further detail, please refer to chapter 9.1.3 “AUX Sensitivity Selection”.

At last, the channel’s volume setting has to be achieved using the corresponding channel control (4). Ideally, volume controls are set to a position somewhere in the area of their center mark (0 dB), leaving you enough reserve for compensating level differences between the audio signals of various input channels.
