4.1 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 dB” or, in case of very high signals, to
the position “−40 dB” .
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 ampli-
fiers operating in bridge mode; they will
be short-circuited by the DI Box .
The output voltage of the amplifier may
not exceed 32 V; otherwise, the DI Box
may be overloaded . This means: Max . of
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
dB”), and, if necessary, in
case of low volume, to the mid-position
“−20 dB” .
4.2 Using the feed-through output
To route the instrument signal directly to
the amplifier, connect the amplifier input to
the jack PAR . OUT (4) . The signal received
from the instrument is directly available at
this jack .
Attention!
The feed-through output is not suitable
for connecting speakers . Risk of overload!
4.3 Connecting the balanced output
Use a balanced cable to connect the XLR
jack OUTPUT (1) to a high-sensitive input of
a mixer (e . g . microphone input) .
4.4 Groundlift switch
When the groundlift switch (2) is in the
position “OFF”, the ground of the unbal-
anced input (3) is connected to the ground
of the balanced output (1) . This switch po-
sition should be chosen first . However, in
case of hum loops, set the switch to the
position “ON”; the ground between input
and output will be galvanically isolated .
