ARCAM Multi-zone amplifier MZ8. Arcam is one of the world’s most respected audio companies. The MZ8 brings all of Arcam’s audio amplifier expertise to the multi-zone amplifier arena delivering superior sound and ease of use and installation at a competitive price. The MZ8 offers stunning sound quality for up to eight speakers for a dedicated custom installation or as a complement to a Receiver for driving extra speakers. This particular unit was used to drive six Atmos ceiling speakers as a complement to an Arcam AVR30 for a home cinema 7.2.6 sound system. The MZ8 is a 3U high chassis and after an equipment upgrade my 19” rack only has space for a 2U unit hence the reluctant sale. Using Arcam’s audiophile amplifier technology the MZ8 delivers a full 65wpc, all channels driven into an 8 ohm loudspeaker load. Massive heat-sinking and a temperature controlled forced air cooling system ensure the MZ8 runs at low ambient temperatures, dispersing less heat into cabinets and aiding long term reliability. Oversized torroid based power supplies allow each amplifier channel to deliver effortless power with a low noise topology improving transient response. RS232 and 12v trigger control offer easy integration within a custom installation. Please look carefully at the photo’s because although in perfect working order the unit has a small dent in the rear chassis (not viewable) when in rack or sitting on a cabinet top. The unit comes with a full manual in .pdf format as email or as a printed copy if required. The amplifier will be well packaged and double boxed to arrive in the same condition it leaves me.
