Crown Reference Macro Amp...I am unsure if it works however i was told that it does. When you plug it in and flip the breaker the fans hum to life and the screen lights up. I have heard that these amplifiers are fantastic i just do not have the use for one. Description:Solid-state stereo power amplifier. Power output: 760Wpc into 8 ohms (28.8dBW),1160Wpc into 4 ohms (27.6dBW), 1500Wpc into 2 ohms (25.75dBW), all at <0.02%THD, both channels driven. Input sensitivities: Studio version: switchablebetween 775mV for full output and 26dB voltage gain. Esoteric version:switchable between 1.4V for full output and 26dB voltage gain. Input impedance:10k ohms (balanced), 5k ohms (unbalanced). S/N ratio: >120dB (A-weighted)below rated output at 26dB gain. Bandwidth: 3Hz--100kHz. Damping factor:>20,000, 10--200Hz; 1800 at 1kHz.Dimensions: 19 W by 7 H by 18.75D. Weight: 56.5 lbs.
