Connecng to the Power Amplier Using the Speakon HIGH-LEVEL INPUT
To engage the Neutrik Speakon plug, insert fully into socket and rotate clockwise unl locked.
To remove the Neutrik Speakon plug, grip body of plug, place thumb on chrome lever, move lever backwards,
rotate plug anclockwise 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 amplier or basic amplier. 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 System. This is a very important point and together with
REL’s Natural RollO™ circuitry, ensures far superior system integraon of the Sub-Bass System with the
main system.
HIGH-LEVEL INPUT: Connecons should be made to the same binding post on main amplier as the main
speakers. Red to amplier main right speaker red terminal, yellow to amplier main le speaker red terminal
and black to amplier main speaker black terminal, right or le but not both. Plug the Neutrik Speakon plug
into the HIGH-LEVEL Speakon socket. Note: This connecon does not draw power from the power amplier
and, yes, your REL is a powered sub bass system. However, by deriving its signal from the main power
amplier, beer sound quality is achieved.
.1/LFE INPUT: This requires a phono-to-phono cable and is a dedicated true .1 channel. This circuit therefore
eliminates the normal Natural RollO™ Crossover and passes the .1 LOW-LEVEL signal through with only the
required 120Hz fourth-order lter.
LOW-LEVEL INPUT: This single channel phono input allows for convenonal connecon to a preamplier
and should be used in the rare event that a HIGH-LEVEL connecon proves incompable. Plug one end of
a single phono-phono cable into the LOW-LEVEL input jack of the REL and the other end into either the
le or right channel output of your preamplier. Because much sub-50Hz bass informaon is mono, there
is lile need to connect both le and right channels. Should your system require this style of connecon –
HIGH-LEVEL is preferred – addional performance is available by purchasing a second, matching REL and
running each as separate stereo subs.
