Before connecting C
HARISMA
switch the power off at all
connected units.
C
HARISMA
is fitted with both XLR-connectors and TRS stereo
jacks for balanced operation, though the jacks may be used with
unbalanced connections simply by plugging in mono jack-plugs.
The level difference that normally occurs when a balanced
input or output is used unbalanced is automatically compen-
sated for.
Should the need arise to use the XLR connectors in an unba-
lanced system, pin 3 of the XLRs should be grounded. Inserting
a mono jack also unbalances the XLRs:
Both output stages operate in parallel, so it is possible to
connect two different destination units simultaneously, for
example to record to two different media at the same time or
split the output between a mixer and effects processor.
However, only one type of input (jack or XLR) should be
connected at a time – the C
HARISMA
is not intended to be used
as a mixer!
To ensure optimal signal quality, SPL has developed a new
hybrid-component balanced input/output stage using all laser-
trimmed resistors with a tolerance of 0.01%. This approach has
resulted in an exceptionally high CCMR (common mode rejec-
tion); 100 dB at 1 kHz and 80 dB at 10 kHz. As a precaution,
before connecting the C
HARISMA
switch off the power to the unit
and to all connected units.
