Bi-Amping
Bi-amping is the separation of the amplification of low
and high-frequency signals over two amplifiers.
Bi-amping requires the use of two amplifiers per
channel. Normally, your SA30 is used to drive the high
frequency (treble) speakers, while a second amplifier
NET
(such as the Arcam PA240) is used for the lower (bass)
frequencies.
Connect the SA30 to the speakers as described for
USB
single wiring, with the exception that the SA30 should
5V 100mA

be connected to the speaker terminals labelled '
' or 'High Frequency' . Next, connect the PA240 power SUPPLY

amplifier to the ' ' or 'Low Frequency' terminals, as

cables are also required to connect the pre-amp

outputs of the SA30 to the power amplifier inputs of the
second amplifier.
WARNING: The strip of metal on the speakers
connecting the low frequency (LF) terminals to the
high frequency (HF) terminals MUST BE REMOVED.
Failure to do so will result in damage to both
amplifiers, which will not normally be covered under
warranty.
