The IB-04 is a multifunctional device. It
is simultaneously a DI-Box, a head-phone
amplifier, a mixer, a preamp and a boostertype
appliance. It can handle two instrument
input signals at the same time. The
symmetrical output signal from the XLRsocket
can be switched to three different
operating levels: 0dB, -20dB and -40dB.
The signal from the line output (mono
or stereo) can be boosted up to 20dB.
Additionally there are two tone-controls
for this output.
