Connecting Up
Always switch your system off before disconnecting any wires.
ALWAYS connect using the REL HIGH LEVEL input, unless your system simply cannot accommodate this.
While rare, a few esoteric systems, such as those that deliver a pure digital signal to active speakers, preclude
this possibility. To increase the versatility of connecting up, the TZERO MKIII has three separate inputs: A
Neutrik Speakon socket and two phono sockets. This is to facilitate use with both two-channel stereo systems
and AV surround sound systems.
The HIGH LEVEL, unbalanced, dual-channel (stereo) input is via a Neutrik Speakon connector which is connected
to the power amplifier’s left and right channel speaker terminals. This has the advantage of ensuring that the
REL receives exactly the same signal as the main speakers. This 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
Active Bass Controller (ABC) ensures far superior system integration of the sub-bass with the main system.
The LOW LEVEL input is via a phono jack that connects to either the .1/LFE output of a home cinema
amplifier/processor or to the output of a stereo preamplifier.
HIGH LEVEL and .1/LFE inputs can be used simultaneously. The benefits are two-fold when used with a
home cinema system. The .1 Input reproduces the .1/LFE channel and the HIGH LEVEL connection underpins
the main front speakers. The main front speakers should be set to the “large” option on the processor. See
“Home Cinema Applications” for more information.
Connecting to the Power Amplifier Using the Speakon HIGH LEVEL INPUT
To engage the Neutrik Speakon plug, insert fully into socket and rotate clockwise until locked.
To remove the Neutrik Speakon plug, grip body of plug, place thumb on chrome lever, move lever backwards,
rotate plug anticlockwise quarter turn and withdraw.
The HIGH LEVEL input is designed to accept the stereo (two-channel) signals from the speaker terminals of
your receiver, integrated amplifier or basic amplifier. 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
