1.3 Safety and Connections
1.3.1 Utilization for the Purpose Intended
The Studer D19 MicVALVE 2-channel Mic/Line valve preamplifier is de-
signed for professional use. It is presumed that the unit is operated only by
trained personnel; servicing must be performed by qualified experts.
The electrical connections may be connected only to the appropriate volt-
ages and signals specified in this manual. Please consult the Security and
EMC section at the very beginning of this manual.
1.3.2 Power Connection
There is no need to select a specific mains voltage setting because the Studer
D19 MicVALVE can be operated on mains voltages from 100 through
240 V
AC
, 50...60 Hz.
Danger: Repair work may only be performed by a trained service technician. The
primary fuse of the D19 MicVALVE must be replaced by a spare fuse of
exactly the same type. The D19 MicVALVE must not be opened by the user
– the risk of a severe electric shock hazard is increased as a result of the
high operating voltage of the vacuum tubes (300 V)!
Power cable: The supplied power socket has to be fitted with a mating power cable incl.
plug by an electrician, if your local Studer agency or your dealer should not
have added a fitting power cable.
