REL R-Series Owner’s Manual 9
Always switch off your system before disconnecting any wires
To increase the versatility of connecting up, the R-Series has three separate inputs; a
high level Neutrik Speakon socket, a Low Level input socket, and a .1/LFE input socket.
As mentioned, this is to facilitate use with both two channel stereo systems and AV
surround sound systems.
The HIGH LEVEL, 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 System. This is a very important point and together
with the REL’s Active Bass Controller (ABC), ensures superior system integration of
the Sub-Bass System with the main system.
The LOW LEVEL input is via a phono connector and connects to the sub or preamp
output of the amplifier/processor. This connection exists in the event that the high-level
connector can not be used, i.e. if you are using active (self-amplified) speakers without
high level speaker terminals. Otherwise it is not the preferred connection method, and
should not be used.
The .1/LFE input is via a phono connector, and connects to the sub or LFE output of
a receiver/processor. This connection is necessary if yours is a multi-channel system,
i.e. if you have a multi-channel preamp/processor in your system and you will be
playing a source with a .1/LFE channel, e.g. most DVD movies and some SACDs.
HIGH LEVEL and .1/LFE inputs can be used simultaneously. The benefits are
two-fold when used with a home cinema system. The .1/LFE input reproduces the
.1/LFE channel and the high level connection provides sub-bass support for the main
front speakers, each input dialed in specific to their function. The main front speakers
must be set to the ‘large’ option on the processor. See “REL Set-Up Made Simple”.
Only after all connections have been made, can the power switch be activated.
