| Rack-mountable chassis |
| Discrete amplifier design for improved sound quality |
| Signal Input Connector: six dual RCA jacks |
| Four-position switch to select Stereo, Bridged Right, Bridged Left or Mono operation for each zone |
| Independent level controls for each amp channel |
| Signal Link Selector: two-position switch to link a zone to the signal input connector of the zone to its left (excluding zone 1) |
| 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 |
| Trigger Input, Euro-style connector, accepts 3V to 24V AC or DC, to "unmute" amp channels in the zone |
