CPA650 INTRODUCTION CPA650 dual channel power amplifiers are designed to supply reliable service in permanent installations. CPA650 amplifiers have complete overload, short-circuit, and thermal protection, with automatic reset. Barrier strip input and 5way binding post output connectors provide trouble free, dependable connections. CPA650 amplifiers are passively cooled for quiet operation, without fan noise or filter maintenance.
IMPORTANT SAFETY INSTRUCTIONS Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. Read these instructions. Keep these instructions. Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. A grounding type plug has two blades and a third grounding prong. The wide blade or the third prong are provided for your safety.

FRONT PANEL FEATURES Channel Peak Indicators: These red LED indicators will light when their respective channel amplifiers have reached maximum output. To avoid clipping distortion, and to protect speakers from being damaged, reduce the input level until the Peak Indicator no longer lights. Channel Level Control Mounting Holes: These holes are provided for optional front panel mounting of the Channel Level Controls (see Channel Level Controls on page 7).
REAR PANEL FEATURES AC Power Entrance: This receptacle accepts the detachable AC Power Cord. The AC Power Cord is for connection to three-prong grounded AC outlets. CAUTION: Do not remove or defeat the ground prong on the AC Power Cord, as this constitutes a shock hazard. The Fuse Clip may be removed by first detaching the AC Power Cord, then prying the Fuse Clip out from above, using a flat-blade screwdriver in the notch provided.
70V MONO-BRIDGE OUTPUT When using a CPA650 to drive a distributed 70V speaker system, a distribution transformer at the output of the amplifier is not required. The CPA650 is capable of driving a 70V line directly. In order to protect the amplifier (and in case of amplifier failure, the speaker transformers) one side of the 70V line must be capacitively isolated as shown below.
PRECAUTIONS Be sure that power to the CPA650 is turned off when making all connections. High voltages can be present at the speaker terminals, and static pops or broken ground connections on cables can cause speaker damage. Use speaker wire of sufficient gauge to prevent power loss and damping factor reduction. Larger size wire has a lower resistance and permits longer cable runs. Use 16 or 18 gauge wire for cable runs up to 20 feet. For runs 20~80 feet, use 14 gauge wire.
