ARCAM / 9-Channel Power Amplifier
Build the theater around the speakers.
The forthcoming PA9 puts nine channels of Class G amplification into a dedicated power amplifier. ARCAM positions it alongside the AVP45 processor, giving a separates-based theater a matching power stage. Its announced architecture also provides dual-mono pairs for bi-amplification flexibility.
Coming soon · Expected March 2027. Timing and final specifications are subject to change.
The House of Stereo perspective
Where the PA9 fits.
The channel plan matters more than the channel count on the carton. We can help allocate power to the front speakers, surrounds and heights, then determine what additional amplification a larger layout needs. The current U.S. schedule lists March 2027. Call to discuss the system and confirm availability; this page is an advance look, not an in-stock promise.
At a glance
PA9 specifications
Announced details and system planning
The announced PA9 is a nine-channel Class G power amplifier, listed at 9 × 100W, intended to partner the AVP45 processor. The announcement describes dual-mono pairs with bi-amplification flexibility. Listed dimensions are 17.1 × 18.4 × 6.7 inches (W × D × H), with a weight of 50 lb.
It supplies speaker power rather than surround decoding. In an AVP45 system, plan one amplifier channel for each passive speaker channel you intend to drive; sixteen-channel processing does not mean nine amplifier channels can power every possible layout. Additional amplification may be needed.
A public owner’s manual and exact-model independent review have not been verified. The announced power figure does not include its test conditions, and bi-amplification configuration, input connections and installation requirements need confirmation from final documentation. These details should be settled before specifying cables or a rack.
