(Examples 6 and 7
on page 35 and 36)
Input gain settings
Offset gain setting / Sensitivity
setting . Different sources often
have different output voltages .
This has a direct influence
on the typical volume level
that is needed for a specific
sound level, hence changing
between sources can result in
high sound level differences .
To accommodate easy
operation, we have included
a gain (or as some prefer to
call it – sensitivity setting) in
our amplifiers – it simply sets
the volume starting point at a
specific volume – to match the
source . The offset-value can be
set from - 12 dB to +12 dB .
