Before connecting the Stereo Vitalizer MK2-T switch the power off
at all connected units.
The Stereo Vitalizer MK2-T 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
compensated for.
Should the need arise to use the XLR connectors in an unba-
lanced system, pin 3 of the XLRs should be grounded. The follo-
wing illustration shows how to properly unbalance a balanced
signal:
Tip: 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 Stereo
Vitalizer MK2-T 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 high CCMR (common mode rejection) values better
than -80dB at 1kHz.
