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