UnBal
to Bal - DI Box
This
is a very practical kit. It converts an UnBalanced
signal to fully Balanced. Once Balanced, the signal
can then be sent to the mixer some distance away without
fear of picking up interference.
It
can also be used as a DI box by musicians. What sets
it apart from other DI Boxes is the incorpration of
a gain control. Though it's at line level, the potentiometer
can be adjusted for a Gain of 6. What this means is
if the input signal is weak, you can amplify it up
to a maximum of 6X. In other words, if your electric
guitar has a output of 0.3V, you can amplify it up
to 1.8V. That is more than enough to drive most power
amplifiers into clipping.
Another
use of this UnBal-Bal converter is in Mono-Bridge.
Connect one output to Channel 1 of a stereo amplifier
and the other output to Channel 2. The loudspeaker
terminals must then be connected to the two red terminals
of the power amplifier. The Black terminals are not
used. Only do this if one is familiar with the Bridging
concept.

The
UnBal - Bal kit requires our PSU15Reg
power supply to work. Alternatively, one can use two
9V batteries and configure them for a split supply
of 9-0-9Vdc.
