Electro-Voice STEREO POWERED MIXER PSX2200 - Manual (Page 23)

All inputs and outputs in the master section are referred to as the MASTER PATCHBAY.
The mixer’s LINE OUTPUTS, RETURNS, and INSERTS are found here. To provide you with a wide variety of connection possibilities, the
MASTER INSERTS, MAIN OUTPUTS, EQ INPUTS and EQ OUTPUTS, POWER AMP INPUTS, and the AUX SENDS and AUX RETURNS
can be independently connected with each other or routed to external devices. In the basic configuration – when no plugs are inserted into
any of the MASTER INPUT connectors – the signals are patched internally and fed to the internal power amplifier. Once you connect a plug
to the INSERTS, EQ INPUTS, or the POWER AMP INPUTS, the internal signal path is interrupted, providing you with the opportunity to
include external signals. We would like to show you some examples of how to use the MASTER PATCHBAY.
1. Connecting an external power amplifier:
If you need to connect more loudspeaker systems than the PSX is capable of handling directly or if you need more power, you have to use
an external power amplifier. Using NF-cables with phone plug-type connectors, you can patch the signal either at the MAIN OUTPUTS – pre
EQ – or at the EQ OUTPUTS – post EQ. In this configuration, the signal path to the internal power amplifier is not interrupted and the audio
signal is outputted to the speaker systems connected to each amplifier.
2. Connecting an additional mixing console:
If you need additional input channels, you have to connect an external mixing console. In doing so you can either use up another LINE INPUT
of the PSX or – as shown in the diagram below – connect the external mixer to the STEREO RETURNS. In combination with the PSX’s stereo
return control, the latter solution offers the additional benefit of matching the level of the additional console to the PSX’s operating level.
