Specifications

Here is a quick overview of the product features- the key word is "flexibility":

12 channels of full-range digital amplification (operates significantly cooler than most multi-channel amplifiers):
45 watts RMS into 8 ohms per individual channel
40 watts RMS into 8 ohms with all channels driven
60 watts RMS stable into 4 ohms (two 8 ohm speakers installed in parallel creates a 4 ohm load; so four 8 ohm speakers installed in one stereo zone - two amp channels - provides a maximum 120 watts per zone)
Each channel is stable to 4 ohms, so you can safely connect two 8 ohm speakers to each channel for a maximum of 24 speakers; example: 6 stereo zones with up to four speakers in each zone
2 side-by-side channels can be bridged to create a single 120 watt channel (8 ohms only)
You decide the combination of 40 watt and 120 watt channels (up to 6 channels at 120 watts each) into 8 ohm load
Two stereo inputs are available to every channel
A separate input is also available unique to each channel (for whole-house audio)
Each channel can independently be selected to play the left, right, or combination (mono) of Inputs 1 and 2
Maximum volume output for each channel can be easily adjusted from the front panel so that you can balance overall sound levels throughout your home (example- limit how loud the speakers can play in your kids' rooms)
All connections are gold-plated for optimum performance
Amplifier can be turned on and off manually or automatically as needed when an input signal, or trigger (for whole-house audio) is detected
Protection circuitry and signal lights make sure you don't overload each channel with too many speakers (a channel will go into protect mode if the impedance drops too low)
Dimensions (HxWxD): 4" x 17" x 14 1/2" not including power cable and volume knobs- Add 1" in back and front for proper clearance
Weight: 29 lbs
Top vented: allow 4" of space above and adequate air flow around amplifier
Power consumption: approx 5 watts in stand-by mode; 1200 watts max all channels fully driven
Color: Dark Charcoal Black
Rack-mount brackets sold separately
