The AC mains supply normally operates at either 50 or 60 Hz
(depending on which country you are in). Under some
circumstances, this can cause an audible hum in your
loudspeakers.
Should you have any problems with hum in your system,
please contact your retailer.
To minimise the possibility of mains hum in your system:
do not link the ground terminals of separate audio units
together.
use screened cable for your signal connections and keep
the left and right channel cables close together.
All the units in the TAG McLaren Audio F3 Series are double
insulated and do not require safety ground connections.
Although a ground terminal is provided on the PA20R, for your
convenience your system does not need to be connected to
ground (audio engineers call this ‘floating’). However, if you want
to ground your system, please contact your retailer who will be
able to assist you.
The audio outputs are intended to connect the PA20R to one or
more power amplifiers (such as our 60P, 100P or 125M).
The low-impedance (100
Ω
) output is buffered and will drive long
cables or several inputs in parallel if required.
OUTPUT 1
and
2
each consists of two phono sockets on the back
panel of your PA20R, one for the
left
channel and one for the
right
(1)
.
Always use high-quality, screened cables for your connections.
