In order to further increase flexibility, the BACH
inputs (channel A, left and right and channel B, left
and right) can be switched from symmetrical to
asymmetrical mode. This comes effective from
September 2021. Four toggle switches positioned
on the rear panel are used for the task.
Changing the mode has no effect on the
outputs! The XLR output still delivers a
symmetric signal, even when the switches
are in the unbalanced position.
In general, when using a balanced phono cable
(wiring #1), the switches should remain in the
balanced position. When using the RCA input
jacks (wired to #2 or similar) the switches can help
to eliminate a hum problem, especially when
using an MM cartridge. In either case, please try
"balanced" operation first.
Since
there
configurations on the market – mainly intended
for unbalanced standard phono amplifiers –
LINNENBERG AUDIO cannot guarantee that a
configuration will automatically work properly.
Sometimes experimenting with different ground
schemes is inevitable. Your dealer will help you if
a problem arises.
