Installation Notes

Installation should be performed by a licensed low-voltage or audio-visual contractor in accordance with NEC guidelines for low-voltage audio equipment. De-energize all connected audio source equipment before wiring inputs and outputs. Ensure adequate ventilation around the unit to prevent thermal buildup during sustained operation. Do not connect speaker loads that exceed the rated output impedance range specified by the manufacturer.
