Installation: Connecting Audio Inputs and Outputs

Audio Connections

Once the input and output cables have been properly wired, they can be connected to the receptacles on the rear panel of the DSP-30.

INPUTS- Input jacks are “combo” style. They accept either male XLR or 1/4-inch diameter TRS phone plugs. Plug line level audio source into the input jacks. Use balanced connections wherever possible.

OUTPUTS- Output jacks are male XLR style. They accept female XLR plugs. Connect the DSP outputs to the next audio device in the signal chain (this is usually a professional audio power amplifier). Use balanced connections wherever possible.

Basic Audio Connections

The basic application shown is representa- tive of most simple installations. The audio source outputs (console output, media player) are connected to the DSP’s input jacks. The audio program material is processed by the DSP and sent out the output jacks. Connect the DSP’s outputs to the next device’s input jacks. This next device is typically an audio power amplifier, but can be other signal- level devices, monitor busses, Ethernet au- dio devices, etc...

As with all professional audio installations, use balanced and fully shielded audio con- nections wherever possible. If connection to an unbalanced source is neccessary, use an audio unbalanced-to-balanced converter (au- dio transformer or active-DI box) to properly isolate the source. If this is not possible, we recommend that the unused minus ( - ) termi- nal be connected to ground (the shield) in order to minimize noise.
