Onkyo PR-SC5507 9.2 Channel AV Network Controller

The Onkyo PR-SC5507 is a dedicated A/V preamplifier/processor (pre-pro)—a component designed to handle decoding, switching, and processing, while relying on external power amplifiers for speaker drive. Positioned as a high-end control centre in its era, it was built to deliver reference-level home theatre performance, particularly in large, multi-channel installations.

Unlike conventional AV receivers, the PR-SC5507 omits internal amplification entirely, allowing for greater flexibility, reduced internal noise, and superior scalability when paired with quality external amplification. Its THX Ultra2 Plus certification further underlines its intent—engineered to meet demanding standards for large-room cinematic playback.

At its core, the unit supports 9.2-channel processing, with extensive balanced and single-ended outputs, enabling complex system configurations including front height and width channels. It integrates advanced processing technologies of its time, including Audyssey MultEQ XT, and a comprehensive suite of Dolby and DTS formats.
