USER’S MANUAL / bit Tune /

The measurement checks the correct polarity connection of the speakers or amplifiers. The operation can be
performed with an Audison bit processor connected to the audio system (fig. 1, 2 and 3) or simply by connecting
the output of the bit Tune to the input of the amplifiers (fig. 4).
*
Connect the LPM microphone cable to the corresponding Bit tune connector. The LPM microphone is placed at
about 20 cm from the speaker to be measured.

IMPORTANT:
In the processors you
should enable the AUX input
if you use a bit Ten/D or AUX1
if you use a bit One through
PC software. This can be disabled
after the measurements. If you want to
connect the bit Tune to AP bit amplifiers to
perform measurements, but the AUX input
port is already occupied, you can use the
OPTICAL input port
(see section 4.5.6)
