5. Connecting DSi 8M inputs to power amplifier outputs:
two options
Option 1: If you have Crown DSi power amplifiers, use six VGA
cables as shown in Figure 3.1 and Figure 3.4.
Option 2: Connect the amplifier loudspeaker outputs to the DSi
8M’s Phoenix input connectors I and J as shown in Figure 3.5.
Unshielded wire can be used. Section 5 gives the connector pin
assignments.
All the inputs on the rear panel are unbalanced except for the
sub woofer input.

4.1 Setting Monitor and Bargraph Levels
1. Set the cinema processor main fader and amplifier
levels so the house speakers are playing back at the
normal listening level. Select some source material like
pink noise.
2. On the DSi 8M, set the Processor/Amplifier Switch to
“Processor.” With the monitor volume set at 7, adjust
the Processor Trimpot for a comfortable listen ing level.
Set the Bargraph Trimpot for a reading in the middle
range.
3. On the DSi 8M, set the Processor/Amplifier Switch to
“Amplifier.” A djust the amplifier trimpot so the level
matches the processor level.
