Bi-Amping - Arcam HDA SA10 Manuel

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 SA10/SA20 is used to drive
the high frequency (treble) speakers, while a second
amplifier (such as the Arcam P429) is used for the lower
(bass) frequencies.
Connect the SA10/SA20 to the speakers as described
for single wiring, with the exception that the SA10/SA20

should be connected to the speaker terminals labelled
VOLTAGE
'HF' or 'High Frequency' . Next, connect the P429 power
amplifier to the 'LF' or 'Low Frequency' terminals, as
SWITCH POSITIONS
115 = 110 - 120V ~
shown in the diagram. A pair of audio interconnect
230 = 220 - 240V ~
cables are also required to connect the pre-amp
outputs of the SA10/SA20 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.
In this example, the P429 is configured in bridge mode.
Refer to the P429 user manual for various configuration
modes.
