3 Operation
The DI Box does not need any power sup-
ply . In the text below, only channel A is
described . Proceed in the same way to set
channel B into operation .
3.1 Connection of the input
Connect the output of the musical instru-
ment to the jack INPUT (3) . Set the sliding
switch ATT . (5) to the left stop ("0 dB") .
If there are any distortions on the subse-
quent mixer, set the switch to the position
"−20" or, in case of very high signal levels,
to the position "−40" .
Alternatively, connect the input jack to the
speaker output of an instrument amplifier
to transmit the effect of the amplifier on
the sound .
Attention!
Do not connect speaker outputs of am-
plifiers operating in bridge mode; they
will be short-circuited by the DI Box .
The output voltage of the amplifier must
not exceed 32 V ; otherwise, the DI Box
may be overloaded . This means: 125 W
with an 8 Ω speaker or 250 W with a 4 Ω
speaker .
Set the sliding switch ATT . (5) to the right
stop ("−40 "), or, if necessary, in case of
low volume, to the mid-position "−20 " .
