AP-48 Eight-Channel "Power Amplifier"

Designed to seamlessly integrate with the Russound PR-4Z, Multi-Source/4-Zone Controller. The AP-48 provides flexibility and audiophile sound quality with a rugged engineering design capable of withstanding rigorous use. Oversized power supplies using Toroidal High Current transformers assure optimum performance under even the most demanding circumstances. These toroids allow extreme current and voltage demands to be met even when all amplifiers are operating at full output. Because of these demands, this design calls for extra large heat sinks needed for excellent heat dissipation. As an added margin of safety, the individual amplifiers utilize independent thermal and short circuit protection circuitry. Another feature of this amplifier is its unique Main Bus switch that selects either Main Bus audio input or the dedicated Line Audio input. The Main Bus input allows each one of the stereo amplifiers to select the same audio source that is on the main Bus input, a useful and easy way to send the same source to several zone amplifiers. The Main Bus audio output also loops the main audio out, for daisy-chain connection to another AP-48 amplifier. The AP-48 offers the ability to switch each amplifier zone to Stereo or Mono. By switching from Stereo to Mono, the left and right outputs in that zone are combined, providing two equally powered Mono outputs. Zone amplifiers can be switched independently, so that zones with multiple speakers will hear Stereo, while those with a single speaker get a Mono signal. This is an excellent outdoor speaker solution as well as rooms with acoustically challenged situations.
