It is very important to confirm correct connection to all amplifiers. The DSP 600 has the ability to configure each output
for a specific frequency range; sub, low freq, mid freq, high freq. You must make sure that each output is connected to
the correct amplifier and loudspeaker(s). Incorrect connections could lead to unexpected results or damage to loud-
speaker components. Note also that each preset in the DSP 600 includes DSP and bandpass parameters for the output
channels. It is possible for a new preset to change an output from Hi to Sub, for instance. Make sure that connections
to amplifiers and loudspeakers are correct before using a new preset.

The final step in setting up, installing and connecting the DSP 600 is to set proper input levels to the unit. The DSP 600
does not itself have input level controls. Proper input level setting is accomplished by setting the output level from the
(L / R) bus outputs from the connected mixer (or other audio output device). The input meters monitor the input level
of either analog or AES/EBU inputs, depending on the input mode selection set in the Setup Menu. Optimal signal-to-
noise performance is obtained when the nominal (average), input level consistently lights the +6dBu (green) and
+12dBu (Yellow) LED indicators. As the DSP 600 is a digital audio device – and digital clipping produces very unpleasant
results – the Clip (red) LED should never light. If it does, reduce the output level of the connected mixer.
Input levels to the DSP 600 can be reduced 6dB to compensate for higher-level output from mixers and other audio
devices. For ideal signal to noise performance when connecting the DSP 600 to high output level devices, engage the
6dB PAD rather than turning down the output of the connected device.
