1. Secure the amplifier in the rack with eight screws (not supplied), four in front, four in back. For complete instructions, refer to TD-000050 "Rear Rack Ears Installation Guide" which can be found on the QSC Website (www.qsc.com) CAUTION! Be sure that nothing is blocking the front or rear ventilation openings, and that each side has a minimum of 2 cm clearance. - Page 7 The analog inputs are converted to digital audio in the DPA-Q amplifiers then routed to the Q-SYS Core over the Q-LAN network. The digital signals show up in Q-SYS Designer at the DPA input component where they can be routed as needed. Refer to the Q-SYS documentation. 1.

Page 21: Full Power
Heat Loss and Current-Draw Charts Heat losses are the thermal emissions from an amplifier while it is operating. It comes from dissipated waste power—i.e., real AC power in minus audio power out. Measurements are provided for various loads at idle, 1/8 of average full power, 1/3 of average full power, and full power, with all channels driven simultaneously. -
