Connections/Operating options
The PowerPac 4003 DSP offers the user numerous possible uses:
The power amplifier has 3 output channels, 1x 2500W @ 4Ω and 2x 800W @ 4Ω. A second subwoofer á 8 ohms
and up to 4 top parts á 8 ohms can be connected. Channel 1 of the PowerPac
4003 DSP drives the subwoofer (8Ω).
This receives 1250W into 8Ω. (see application 1)
If you add another subwoofer (8Ω) to channel 1, the impedance is reduced to 4Ω. The 2500W (which are available
on 4Ω) are now shared between both subwoofers and each speaker receives 1250W into 8Ω. (see application 2)
•
Calculation example: 1250W 8Ω + 1250W 8Ω = 2500W 4Ω
For all stereo applications the LINE signals from the mixer has to be connected to the PowerPac 4003 DSP as
follows:
