CONNECTING UP

To connect to the power amplifier using the UNBALANCED Neutrik high
level input.

To remove the Neutrik Speakon plug, grip body of plug, place thumb on chrome lever, move
lever backwards rotate plug anti-clockwise (counter-clockwise in the US) quarter turn and

The high level input* is designed to accept the stereo (two channel) signals from the speaker
terminals of your receiver, integrated amplifier, and basic amplifiers. This has the advantage
of ensuring that your subwoofer receives exactly the same signal as the main speakers,
which means that the character of the bass from the main system is carried forward into the
sub-bass. This is a very important point and together with the REL’s ABC circuitry, ensures
far superior system integration of the sub-bass with the main system.
*This input is labeled “Unbal Hi Input” on Stentor III and Studio III. This is the most
common or standard recommended means of connecting the sub for two channel use.
