The DIRECT IN stereo input is used to apply the signals coming from an external source. When using the DIRECT IN input, the MAIN signal applied on the rear panel is interrupted automatically (fig. 3.2).

The INPUT LEVEL control adjusts the level of the input signal inserted via the rear panel MAIN INPUT or DIRECT IN connectors.

The 4-digit INPUT LEVEL meter informs you about the current input level within a range from -24 dBu to +6 dBu.

The HEADPHONE OUT is connected in parallel to the rear panel output connectors, and provides an additional option to monitor the individual channels. When the unit is permanently installed in rack, this proves to be a useful function.

A further input signal can be added to the MAIN and/or DIRECT IN signal via the AUX IN (fig. 3.2). The L MUTE switch mutes the left input signal.

This R MUTE switch mutes the right input signal.

With the MONO switch each of the amplifiers can be switched between stereo to mono mode, and vice versa.

The BALANCE control determines the ratio level between the MAIN/DIRECT IN signal and the input signal applied to the AUX IN input.

The OUTPUT LEVEL control determines the volume of the individual amplifiers and refers to both the left and right channels.

The 4-digit OUTPUT LEVEL meter informs you about the current output level within a range from -24 dBu to + 12 dBu. If the CLIP LED lights up, you have to decrease the INPUT GAIN, otherwise distortion will raise.
