Digital Amplifier Compatibility
HI Level Inputs on the REL G1 incorporate proprietary REL-D™ circuitry to allow the use of amplifiers using Class D
topology without grounding issues.
LED Display
An LED display is located on the lower front of the G1. All functions that are user adjustable via the remote control can
be seen here. The display reverts to off a few seconds after adjustment.
Remote Control Battery Installation
The G1 Remote Control Unit requires two AAA batteries. These are not installed but are supplied. To install or replace
batteries in the Remote Control Unit, first remove the bottom aluminum cover by using the supplied 7/64” Allen key to
loosen the two visible screws. With the bottom cover removed, you will see a battery holder, which will accept two AAA
batteries. Follow the images on the holder for proper orientation of the batteries. After installing the batteries, test the
unit by setting the SECURITY switch to UNLOCK and turn one of the knobs. If the batteries are installed properly, you
will see one of the red LED’s on the remote control’s front panel illuminate. Replace the bottom cover and tighten the
two screws using the supplied Allen key. Please note that battery life can be extended if the SECURITY toggle switch is
left in the LOCK position when the Remote Control is not in use.
Remote Control Address Selection
The G1 remote control unit provides an address selection function to allow multiple sub-bass systems to be used in
an audio system with a separate remote control for each. Additionally, if the remote control of the G1 interacts with
any other piece of equipment in your system or if other remotes interact with your G1, the address can be changed
to avoid unwanted interaction.
Phase Switch
Used to set phase. Phase Switch on remote control is monentary. Refer to display for 0 or 180 degree status. Phase
selection affects both Hi and Lo Level inputs.
Connecting Up
Always switch off your system before disconnecting any wires.
To increase the versatility of connecting up, the G1 has two separate stereo inputs. A Neutrik Speakon socket and two
phono sockets. This is to facilitate use with various system configureations.
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.
There are two RCA sockets for Low Level connection to the output of a stereo preamplifier or receiver. Another single
RCA socket connects to the .1/LFE output of a home cinema amplifier or processor.
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”
