[QUOTE="Brian Jones, post: 27454, member: 257"] Re: Thoughts about amplifiers at 3/4 volume. I think you have that backwards. I own a Crown iTech and in the application guide it talks about attenuators and input sensitivity. Unlike most amps, the iTech's input sensitivity is adjustable. It also has attenuators like most amps. It talks about the best way to reduce maximum output power being adjustment of the input sensitivity because that will result in better SNR. This is especially useful when using it with a speaker with a lower than recommended power rating. The 8000 produces 4000w @ 4 ohms per channel and I use it to power an SRX728S on one channel and a pair of SRX712M's as mains on the other channel. Both present a 4 ohm load and are both rated at 1600w RMS/3200w program so I adjust the input sensitivity and leave the attenuators at 100%. Technically, with the Itech, you would use the same knob to adjust both input sensitivity and attenuation with it's menu driven system but it doesn't have a level marking on the knob for obvious reasons and when not in menu mode, the knobs adjust attenuation. Most amps though, like I said, have fixed input sensitivity. [/QUOTE]
