Uncompromising Design and Construction using only the best
electrical and electronic components including glass-fibre reinforced epoxy
circuit boards, high-current handling printed circuitry and low-loss solid brass
24 K gold-plated power and signal input connecting blocks/sockets and loud-
speaker terminal blocks.
Integrated Electronic Filtering Option with separate Low- and High-
Pass Filter sections with 12 dB/oct. slopes. The low- or high-pass cross-over
frequencies are continuously variable between 50 Hz and 250 Hz.
Advanced Protection Circuitry 'sensing' short-circuits and DC vol-
tage at the speaker outputs and overheating of power electronics. Faulty
connections or operating modes will cause the amplifier to shut-off imme-
diately.
Operating Mode / Fault Monitor LED monitoring the correct func-
tion of the amp.
1 Ohm Stability for simultaneous connection of several loudspeaker
systems on a 2- or 4-channel amplifier or for Tri-Mode amplification. The use
of a regulated MOSFET power supply provides high power headroom for
low-impedance loads. All amplifiers allow bridging mode for increased
power output, e.g. for subwoofer amplification.
Stereo, Mono-Bridged and Tri-Mode possible without amplifier in-
ternal switching.
Adjustable Input Sensitivity accepting input voltages from 150
mV to 3V allowing system combinations with almost every head-unit on the
market.
Soft Start / Soft Turn-Off Circuitry eliminating any amplifier rela-
ted turn-on/turn-off noises.
Easy Access Fuse(s) on the control panel.
