That new preamplifier is built in a modulated structure, that is to say that the different functions are reassembled on removable PC boards and all is foregone to add - without any adjustment - at each moment a new PC board, either to hold a new function, or to " upgrade " an existant function.

The housing is ingeneered to carry out a maximum rigidity by the using of a 25/10 thickness steel sheet which protects in the same time against the different electromagnetical rays.
The front plate is available in 2 versions, one is standard light grey laquered and the other in 10mm aluminum finely brushed and champagne coloured.
The external power supply conductes to a very attractive, signal/noise ratio especially on the Phono position.
A luxury power supply (see photo) is sold in option : Dual regulated power supply.
INPUT SELECTOR AND WIRINGS
When it is fitted with all its removable PC boards, the preamplifier CONTROL " B " has 5 stereophonic inputs and one input/output in monitoring for Tape recorder which maximum sensitivity and impedance are specified in the following chart:
The volume adjustments are made by separated potentiometers on each channel.
