320 Wpeak into 8 Ohm

600 Wpeak into 4 Ohm

1000 Wpeak into 2 Ohm

160 WRMS into 8 Ohm

300 WRMS into 4 Ohm

Hum and Noise:

Below full power typically: -110 dB (20Hz-20kHz). Minimal unweighted: better than -100 dB

Input:

Proprietary electronically balanced discrete enhanced 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 411 MK-II

Input Impedance:

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