ampliers feature active bias control throughout,
with thermal sensing that carefully manages
the temperature and current ow at different
volume levels.
Fully DC-coupled, the signal path contains no
capacitors, while those in the power supplies are
audiophile grade components.
The ampliers are of a unique low-feedback
design for minimum transient and interface dis-
tortion, offering superb clarity and transparency
right across the audible range, with an output
impedance that is close to zero and suitable
for virtually any high-quality third-party passive
loudspeaker system.
Trigger capability allows the G56 to be switched
on remotely by means of a signal from your pre-
amp. Trigger and other control signals are opti-
cally isolated from the amplier itself. When in
stand-by mode, a standing voltage is maintained
on the power rails and supply components. As a
result, you do not have to wait for half an hour
after switching on for optimum performance to
be achieved: it is there immediately.
Two sets of outputs are provided per chan-
nel for bi-wiring, etc, on sturdy binding posts
colour-coded for easy reference and capable of
handling large-diameter high-quality loudspeak-
er cables. The output terminals are connected to
the ampliers by Van den Hul silver-strand cable
to avoid signal losses.
The amplier can be operated in bridge mode
by actuating a switch on the rear panel, in
which case the left channel input becomes the
input for the bridged pair and the inner output
terminals are bridged, power being derived
from the outer terminal pairs (see rear panel
diagram).
The ampliers include electronic protection
reset by power-cycling, with full DC and thermal
protection.
A front-panel indicator shows when the ampli-
er is in standby. When the unit is activated, an
LED illuminates for each channel. In the event of
thermal overload, the main indicator goes red
and the channel lights go out, showing that the
unit is off-line. A pushbutton on the front panel
can be used to take the unit in and out of stand-
by, while exible 5–30V AC/DC trigger capability
allows amplier power to be controlled remotely
along with the rest of a system.
