CONNECTING YOUR TORUS INFRASONIC GENERATOR
USING THE TORUS INFRASONIC GENERATOR
WITHOUT THE TORUS AMPLIFIER
To achieve the best results, it is strongly recommended that the Torus Infrasonic Generator is
driven by the Torus Amplifier. It is designed and built for this purpose and offers the user many
controls to help integrate the Torus Infrasonic Generator seamlessly into any two channel
and/or A.V. system. These controls include variable phase adjustment, gain, crossover
frequency adjustment and a parametric E.Q. for rolling off the signal below four preset
frequencies. These controls are detailed on pages 21 and 22 of the Torus Amplifier manual.
When employing one infrasonic Generator, whilst driving it with a standard amplifier may be
possible, without the right signal processing offered by the Torus Amplifier or an A.V. multi
channel amplifier, only bass energy from either the left or right hand channels could be sent to
the Infrasonic Generator which may lead to an imbalance on some program material. Standard
amplifiers will also not provide crossover frequency adjustment controls and this will make the
task of integrating the Torus with your main loudspeakers a much more difficult task.
A multi channel power amplifier, fed by a multi channel preamplifier with a dedicated subwoofer
channel would be the most suitable option in the absence of the dedicated Torus Amplifier. A
suitable multi channel system should mix bass energy from all relevant channels to a mono
signal, to get the best balance between all of the channels. Some multi channel systems may
also offer further options for adjusting the signal sent to the dedicated subwoofer channel.
If you have not purchased the Torus Amplifier, the Torus Infrasonic Generator can be
connected to the terminals of a suitable amplifier in the same way as the Torus Amplifier as
shown in figure 4 on the previous page.
