In Jacks
Connect the shielded audio cables from your preamplifier or system controller’s output jacks
to the Model 2250’s L and R audio Input jacks. Use only the R channel jack for mono operation.
Loop Jacks
The jacks replicate the audio input signals to facilitate connections of other power amplifiers to the same preamplifier or system controller. Loop connection of multiple power amplifiers is called a “daisy chain.”
Note: You may loop the trigger connections of multiple Parasound power amplifiers without overloading the surround controller or preamplifier trigger outputs.
