Here is a quick overview of the product features- the key word is "flexibility":
12 channels of amplification:
75 watts RMS into 8 ohms (over 100 watts music listening) per individual channel
65 watts RMS into 8 ohms (over 80 watts music listening) with all channels driven
100 watts RMS stable into 4 ohms
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 150 watt channel
You decide the combination of 65 watt and 150 watt channels (up to 6 channels at 150 watts each) into 8 ohm load
Two stereo inputs are available to every channel
A separate input is also available unique to each channel
Each channel can independently be selected to play the left, right, or combination (mono) of every available input
Maximum volume output can be set for each channel 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 automatically as needed when an input signal, or trigger, 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)
