THE BEAUTY OF POWER US SERIES AMPLIFIERS

WIRING

There are multiple ways to connect a US-Series ampli- fier to other audio equipment. The US-Series features balanced inputs and link outputs, which allows you to connect both balanced and unbalanced signals.

For speaker connections, you can use either binding posts or Speakon™ connectors.

NOTE: Use speaker wires with the lowest gauge available. The thicker the speaker wires are, the less output signal you will lose.

NOTE: For connections of unbalanced sources via balanced cables / plugs, the ring and sleeve have to be bridged at the TRS plug.
