2.7 Indication of the Operation Mode

Two LEDs on the power amp’s front panel indicate the currently selected mode of operation. The PARALLEL-LED lights yellow, when the ROUTING switch is set to PARALLEL. The PARALLEL LED does not light, when the switch is set to DUAL. The BRIDGED LED lights yellow, when the MODE switch is set to BRIDGED. The BRIDGED LED does not light, when the switch is set to NORMAL.

2.8 Selecting the Mode Of Operation

ROUTING

The ROUTING switch on the power amp’s rear panel defines how the audio inputs handle the input signals.

DUAL

In DUAL mode, the two channels of the power amplifier work independent from each other. This mode of operation is being used for all 2-channel applications, like stereo or Bi-Amp (active) operation. Using the input level controls on the power amp’s front panel or an optionally available remote control module and IRIS-Net™ allows independently adjusting the channels’ amplification.

PARALLEL

In PARALLEL mode, the inputs of channel A and channel B are directly electrically linked. The audio signal has to be applied to the input connectors (XLR or Phoenix) of channel A. Using the input level controls or IRIS-Net™ to independently control the amplification of the two channels is still possible because only the channels’ inputs are linked. PARALLEL operation is the mode of choice, whenever the same input signal drives multiple power amp channels of a large system installation, e.g. when driving massive bass arrays.

CAUTION:

In PARALLEL mode, the input signal has to be fed to input channel A only.
