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