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.

NOTE! AC line cord omitted for clarity. Ensure AC power is properly connected.
