Connections Using a Multi‐Channel Preamp/Processor with Speakers
The diagram on the preceding page depicts an UPA‐7 connected to an Emotiva UMC‐1 Multi‐Channel Processor/Preamplifier. Your personal setup may differ, depending on which amplifier you own, and how many channels you are using. The UPA‐7 is simply shown as a basic example.
The image shows a basic 5‐channel surround configuration connecting the RCA/Unbalanced outputs on the processor to the RCA/Unbalanced inputs on the amplifier.
Note that each channel on the UPA‐7 has been switched to ‘Un‐Bal’ (for an RCA/Unbalanced connection) using the Balanced/Unbalanced Selectors. If the selector does not match the connection type, the amplifier channel in question does not pass the signal to the speakers, and that channel will remain silent.
The preamplifier outputs on the processor are labeled as follows:
L (Left), LS (Left Surround), C (Center), LBS (Left Back Surround), R (Right), RS (Right Surround), SW (Subwoofer), and RBS (Right Back Surround).
Connect the outputs from the processor to the amplifier channels you wish to use to power each speaker.
Example: You plan to use Channel 1 on the amplifier to power your front left speaker. With an RCA/Unbalanced cable, connect the output labeled ‘L’ to the unbalanced input on amplifier Channel 1. Then, connect the speaker terminals from amplifier Channel 1 to your front left speaker. Continue this process for all connections, making sure to keep the outputs, inputs and speaker terminal connections in order.
If your processor/preamplifier has XLR/Balanced outputs, the Balanced inputs on your X‐Series amplifier may be used. Simply switch your channel selectors to ‘Bal’, and use the XLR/Balanced outputs on the processor, and the XLR/Balanced inputs on each channel of the amplifier.
Surround Speakers Note: In a standard five channel configuration, LS (Left Surround) and RS (Right Surround) are used, and LBS (Left Back Surround) and RBS 9 (Right Back Surround) are left unused. In a standard seven channel configuration, LBS and RBS are included.
Subwoofer Note: As seen in the diagram, the subwoofer output on the processor (shown as a XLR/Balanced connection) goes directly to the subwoofer itself. This assumes that the subwoofer has its own amplifier. If the subwoofer has a separate amplifier, the processor output would first go to the input of the amplifier, then to the subwoofer.
