Connecting Up
Always switch off your system before connecting or disconnecting any wires.
T
o increase the versatility of connecting up, each Serie R model is equipped with two separate inputs. A Neutrik
Speakon socket and a single phono socket. 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 two separate phono jacks that connect to either the .1/LFE output of a home cinema
amplifier/processor or to the subwoofer output of a stereo preamplifier.
HI LEVEL and .1/LFE inputs can be used simultaneously. The benefits are two-fold when used with a home cinema system.
The low level input reproduces the .1 Sub/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”
Connecting to a Power Amplifier Using the Neutrik 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 anti-clockwise 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, 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 System. This is a very important point and together with REL’s Natural RollOff™
circuitry, ensures far superior system integration of the Sub-Bass System with the main system.
High-Level Input: Connections should be made to the same binding post on main amplifier as the main speakers.
Connect as shown above. Red to amplifier main right speaker red terminal, yellow to amplifier main left speaker red
terminal and black to amplifier main speaker black terminal, right or left but not both. Plug the Neutrik Speakon plug
into the HI LEVEL Neutrik socket.
