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.
