Bi-amping using an external power-amplier
To bi-amplify your speakers using one or more external power ampliers, you will need as many
channels of amplication as there are channels you wish to bi-amplify. For example, to bi-amplify just
the front left and right channels, a two-channel amplier such as the Arcam P90 is required; to bi-
amplify all seven channels, either multiple two-channel ampliers or a single seven-channel amplier (or
some variation thereof) are required.
Connect the pre-amplier outputs of the AVR350 to the line inputs of the power amplier(s) you are
using. If multiple two-channel power ampliers are in use, it is recommended to route pairs of channels
through the same amplier (e.g., the front left and right channels should be amplied by the same
amplier).
Connect the HF terminal of your speaker to the correct speaker terminal of the AVR350 (the AVR350
amplication circuits will be used to provide the high-frequency signals); connect the LF terminal of
your speaker to the correct speaker terminal of the power amplier (the power amplier will be used to
provide the low-frequency signals).
Ensure that in all cases, the positive terminals on the speakers are connected to the positive (red)
terminals on the amplier, and similarly for the negative (black) terminals.
