Update / Upgrade     This  unit can be kept up to date with the current state of development by
fitting an update or upgrade .
-
An Update expands the unit’s operating facilities by the installation of a new
program memory.
-
An Upgrade involves the installation of replacement sub-assemblies or
auxiliary modules. The installation or conversion work is carried out by your
specialist
 dealer.
Volume control     The amplifier features a two-stage volume control which enables the unit to
work at a high level of amplification in the input stage of the pre-amplifier,
without risking overloading the pre-amplifier.
This is the responsibility of the first volume control. In the subsequent stages of
signal processing the amplifier has a higher-level signal to handle, and this in
turn significantly reduces hiss and crossover distortion where the signal passes
through zero.
The second volume control reduces any hiss generated in the pre-amplifier at
low levels directly before the output stage.
