"Luxman M-03
power amplifier is rated at 200 Watts per channel into 8 ohms and is suitably
massive, with huge vaned heat-sinks, each weighing 15kg, running along both
ends of the chassis, and a power supply based around two 15,0001.tF block
capacitors for each channel. There is provision for combined (bridged) mono
operation when the power rating becomes 480 Watts into 8 Ohms. This mode is
called BTL (Balanced Transformerless) and must be deliberately selected on the
rear panel, where a security plate has been fixed at the factory to hold the
switch in its normal stereo position."
"Separate left
and right channel attenuators are situated on the front panel and there is also
a two-channel digital display of peak power level in Watts. A switch gives a
choice of 1 or 3 seconds hold-time for the peak reading to make for easier monitoring
under various programme conditions or, if you find the display distracting, it
can be switched off. The power reading is related to the nominal loudspeaker
impedance value selected on a three-position switch on the rear panel (4, 6 or
8 Ohms). Heavy duty terminals are fitted for two pairs of loudspeakers and
front panel switches select speakers A, B, A + B or both off. "
"M-03 power
amplifier handbook shows how it would be possible to operate the C-03
preamplifier into two M-03 power amps each in the BTL mono mode to provide a
hefty 480 Watts-per-channel (neighbours, ears and loudspeakers
permitting)."
