WARNING: Do not connect the outputs of one channel to the outputs of other channels or to other amplifiers.

Provides a line-level RCA connector loop/passthru output for connecting multiple DD-8 amplifiers in a system utilizing a single bus input signal.

If the DD-8 is used as a single zone amplifier and the input signal is connected via the Bus Input, that signal can be output via this pair of RCA connectors to additional DD-8 amplifiers connected in the same manner.

NOTE: The number of DD-8 amplifiers that can be connected in this manner is limited by the output voltage of the signal source device driving the bus input as it must support the total impedance of all of the bussed devices.

2. Bus Input

Provides a line-level RCA connector input to simultaneously feed all speaker output channels utilizing a single bus input signal.

When the DD-8 is used as a single zone amplifier, all channels can be driven using only the bus input without the need for connection to each channel’s local input individually. If the bus input is used with the DD-8 configured for stereo operation, the Left input signal will be routed to all four Left speaker outputs and the Right input signal will be routed to all four Right speaker outputs.

If the bus input is used with the DD-8 configured for all mono operation, either the Left or Right Bus Input RCA connector can be used to feed all eight speaker outputs. (See the section on “Stereo/Mono Selection” for more information.) In this case, using only one input connector will attenuate the gain by 6dB. A “Y-adaptor” RCA cable can be used at the input to maintain full gain if desired.
