Minimum Power Output:

140 W peak into 8 Ohms

260 W peak into 4 Ohms

400 W peak into 2 Ohms

70 W RMS into 8 Ohms

130 W RMS into 4 Ohms

200 W RMS into 2 Ohms

Max. Output Voltage: 66 V pp.

Max. Output Current:

Unlimited repetitive peak output current. More than 15 A continuous. No output or DC fuses, absolutely no form of current-, voltage- or any other kind of limiting.

Distortion: 0,005% THD

Bandwidth including Input Filter:

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).

Rise Time at Full Power: 3 uS

Hum and Noise:

Minimal unweighted (20Hz-20kHz) :

better than -100 dB

Input:

Electronically balanced discrete class A circuitry, floating ground, non-inverting or inverting mode.

Optimal performance with either balanced or single-ended sources.

Single-ended sources are automatically balanced right at the input of the FM 108-MKII.

Input Sensitivity:

0.9V RMS for full output

Input Impedance:

At all level settings from balanced and unbalanced sources: 40 kOhm

Interference Rejection:

90 dB typically, better than 80 dB at 50 Hz, even better at other frequencies.

Load Impedance:

No minimum impedance. The amplifier is designed for 1 Ohm to 10’000 Ohm systems. It 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 on board computer that continuously surveys all important parameters.
