Bi-amping using an external power-ampli er
To bi-amplify your speakers using one or more external power ampli ers, you will need as many
channels of ampli cation as there are channels you wish to bi-amplify. For example, to bi-amplify just
the front left and right channels, a two-channel ampli er such as the Arcam P90 is required; to bi-
amplify all seven channels, either multiple two-channel ampli ers or a single seven-channel ampli er (or
some variation thereof) are required.
Connect the pre-ampli er outputs of the AVR300 to the line inputs of the power ampli er(s) you are
using. If multiple two-channel power ampli ers are in use, it is recommended to route pairs of channels
through the same ampli er (e.g., the front left and right channels should be ampli ed by the same
ampli er).
Connect the HF terminal of your speaker to the correct speaker terminal of the AVR300 (the AVR300
ampli cation 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 ampli er (the power ampli er 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 ampli er, and similarly for the negative (black) terminals.
