FM發表了新的單聲道後級：FM 108，售價尚未知，屬於Resolution Series，其A類放大與防護系統與上級機種特性一樣。維持FM不妥協的精神與完全在瑞士手工打造。FM 108體積雖小，但並非使用交換式電源，而是高輸出線性類比電源。



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: Average distortion: 0,005% THD

Bandwidth including Input Filter:
Less than 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:
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 unbalanced (single-ended) sources. Unbalanced sources are automatically balanced right at the input of the FM 108.

Input Sensitivity:
0.9V RMS for full output

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

Input Stage Common Mode 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 onboard computer that continuously surveys all important parameters.
