CONNECTIONS- Audio Connections: XLR Inputs

Audio Connections

Audio inputs can be connected to the XLR inputs OR the DataPort connections (QSControl users). This section provides information on using the XLR Inputs, For DataPort information see page 17.

XLR Inputs

The position of the Mode Switch determines how the input signals are routed. Select your operating mode before making connections. See page 7, Block Diagram.

CH1 and CH2 INPUT - In Combination Mode, use these for 2-channel inputs. For mono input, use Input 3 and leave CH1 and CH2 inputs unused. In Discrete Mode, CH1 and CH2 Input feed the Top Box Processor only.

COMBINATION MODE– CH1 and CH2 INPUT are routed to the Top Box and Subwoofer Processor’s IN1 and IN2 blocks. Alternately, if using a mono input, INPUT 3 is routed to both Processor’s IN1 block. COMBINATION MODE.

Important Note! In Combination Mode, CH1 INPUT and INPUT 3 are connected in parallel (see diagram, previous page. This is why it is necessary to use CH1 and CH2 Inputs OR Input

3.If all three inputs are used while operating in Combina- tion Mode, unpredictable results may occur.

DISCRETE MODE– CH1 and CH2 Inputs are routed to the Top Box Processors only and are in no way connected to the Subwoofer Processor. INPUT 3 is now routed to the Subwoofer Processor IN1. Note, the Subwoofer Processor IN2 block has no input signal connected when operating in Discrete Mode.

INPUT 3- In Combination Mode, Input 3 is used for mono 3- way input to both processors. In Discrete Mode, Input 3 is used for the subwoofer only.

If you are using the DataPort connections for supplying audio to the 215PCM, do not use the XLR inputs.

If you are using the XLR inputs for supplying audio to the 215PCM, do not use the DataPort connections to supply audio.
