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 SA750 is used to drive
the high frequency (treble) speakers, while a
second amplifier (such as the JBL SDA2220) is
used for the lower (bass) frequencies.
Connect the SA750 to the speakers as described
for single wiring, with the exception that the
SA750 should be connected to the speaker
terminals labelled "
HF
" or "
High Frequency
".
Next, connect the SDA-2220 power amplifier
to the " LF " or " LOW Frequency " terminals,
as shown in the diagram. A pair of audio
interconnect cables are also required to connect
the pre-amp outputs of the SA750 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.
