MA-362 Audiophile Quality 12-Channel Amplifier - No Longer Available View: Larger Image
Zoom In: Front | Back
The Audioaccess MA-362 12-Channel Amplifier represents a high-value approach while providing 12 channels of clean amplifier power for multiroom system applications. Power to Spare: With a power rating of 50 watts per channel at 8 ohms from 20Hz to 20kHz with less than .05% THD, the MA-362 will drive virtually any loudspeaker to room-filling volume. Power into 4 ohms is even more impressive at 75 watts per channel. All channel pairs may be bridged if additional power is required. Cool operation is ensured with a design incorporating heatsinks, flow-through ventilation and low-noise fans. Features
hide Rack-mountable chassis
hide Discrete amplifier design for improved sound quality
hide Signal Input Connector: six dual RCA jacks
hide Four-position switch to select Stereo, Bridged Right, Bridged Left or Mono operation for each zone
hide Independent level controls for each amp channel
hide Signal Link Selector: two-position switch to link a zone to the signal input connector of the zone to its left (excluding zone 1)
hide Trigger Source Selector: three-position switch to select signal sensing, voltage trigger input or link (to the trigger signal of the zone to the immediate left) to control muting in the zone
hide Trigger Input, Euro-style connector, accepts 3V to 24V AC or DC, to "unmute" amp channels in the zone
