CONNECTING UP YOUR TORUS AMPLIFIER
Method 1:
USING HIGH LEVEL TORUS AMPLIFIER INPUT
PLEASE NOTE: It may not be possible or advisable to connect the high level input directly to
an amplifier that has a class D digital output. Please check with the supplier of your amplifier
that this form of connection is possible.
PLEASE ALSO NOTE: The high level lead and connection must not
be used with a power
amplifier of dual mono bridged design as this may damage the power amplifier.
The Torus Amplifier can still be connected by the low level input as shown in method 2 if
your power amplifier is unsuitable for high level connection.
It is strongly advised, that the Torus system is installed, by a suitably trained person, to
avoid causing damage or injury resulting from an incorrect installation.
Figure 1. Shows a diagram on how to connect the high level input of the Torus Amplifier. Using
the optional Neutrik lead, connect the Torus Amplifier to the output of your amplifier via your
existing speaker plug or to a spare set of speaker terminals if available. In effect you are Bi-
Wiring your Torus to your power amp. Please note that the Neutrik cable has only three leads
and is arranged this way to preserve the star-earthing of your amplifier (assuming it has a star
earth arrangement).
To connect the high level lead you will need to connect the RED wire to the RED terminal of the
RIGHT hand speaker terminal of your power amp. Connect the YELLOW wire to the Red
terminal of the LEFT hand channel speaker terminal of your power amp. The BLACK wire is
connected to either one of the BLACK speaker terminals of your power amplifier. This is
important as some power amplifiers do not like their black terminals joined. Now plug the neutrik
connector into the high level input of the Torus. The Neutrik plug will fit only one way as it has a
key. Next push the plug in then turn clockwise until you feel it latch. To undo the Neutrik plug,
pull back the silver lever on the Neutrik plug and turn counterclockwise.
