loudspeaker
terminals
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.
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.

connecting loudspeakers
The connection between your 125M and your loudspeakers is
crucial to the sound quality of your entire audio system.
Please follow these recommendations to achieve the best results.
Your 125M is specified to operate with 8
Ω
loudspeakers, but it
can be used with 4
Ω
loudspeakers. The 125M may also be
connected to loudspeakers which have a transient impedance of
less than 4
Ω
(1)
.
Always switch off your 125M before changing any connections.
Always use high-quality loudspeaker cable.
On the back of your 125M you will find a pair of black terminals
and a pair of red terminals. This duplication of the terminals
allows you to bi-wire a loudspeaker as explained on page 19.

load must be used
