Up for sale we have a showroom condition FM Acoustics 811 MK 2 Resolution Series power amplifier. This was FM Acoustics Flagship amplifier up until the newer 1811. It has been very well taken care of and in a smoke free environment. This served as our Reference amplifier for a couple years. It will also come with a 3 meter pair of FM Acoustics Forceline 3 speaker cables which also have a high value. We have had many of the FM Acoustics power amps and preamp over the years which include 711MKII, 611X, 611, 411 MKII, 115 Mono blocks etc. this is by far superior to the other models. for more info please contact Audio Limits (702)299-0567 Website: www.audiolimits.com Email [email protected] payment for this item is accepted by Bank wire transfer or check only

Few Specifications

Minimum Power Output:
900 W peak into 8 Ohms
1700 W peak into 4 Ohms
3000 W peak into 2 Ohms

455 W RMS into 8 Ohms
850 W RMS into 4 Ohms
1500 W RMS into 2 Ohms

Max. Output Voltage: 180 V pp.

Max. Output Current:
Absolutely unlimited peak current.More than 60A continuous per channel allows the FM 811 to drive any known load without any negative influence on the audio signal. No fuses, absolutely no form of current, voltage or any other kind of limiting.

Distortion: Average distortion: 0,005% THD
Gain: 30.5db

Bandwidth including Input Filter: (-3dB)
1 Hz to 60 kHz.
If required, internally settable to any frequency between 1 kHz and 60 kHz (Low-Pass) and
1 Hz to 1 kHz (High-Pass).

Risetime at Full Power: 3 us

Hum and Noise: (20Hz-20kHz).
Below full power typically: -115 dB
Min. unweighted: better than -100dB

Input Sensitivity:
1,2 V RMS for full output

Input Impedance:
At all level settings from balanced and unbalanced sources: 40 kOhms

Input Stage Common Mode Rejection:
100 dB typically, better than 90 dB at 50 Hz, even better at other frequencies.

Load Impedance:
No minimum impedance. Designed for 1 Ohm to 10’000 Ohm systems. Can drive any speaker impedance (even below 1 Ohm) with dynamic (music) signals without any limiting, compression or other negative effects on the audio signal. Despite this, the amplifier is fully protected against short circuits, open circuits and all other adverse conditions via a unique onboard computer that continuously surveys all important parameters.
