CONNECTING UP
Always switch off your system before disconnecting any wires
To increase the versatility of connecting up, the “Q” range has two separate inputs. A Neutrik
Speakon socket and a pair of phono sockets. (single phono socket on Quake and Q108). As
mentioned, 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 phono connectors and connects to the Sub/LFE output of the
amplifier/processor. Two inputs are available, 0dB and +12dB, (Single phono input on Quake and
Q108 at +12dB), it is usual to use the 0dB input but if the Sub/LFE output level of the
amplifier/processor is a little low then the higher sensitivity +12dB input can be used.
If the main speakers are active then again the low level input must be used and connected to the pre
amplifier outputs. Because the low level inputs are 0dB and +12dB an attenuator is necessary to
balance the two inputs, Quake and Q108 are not suitable for this method of connection as it
only has a single channel low level input.
Quake and Q108 also have an input for connection to a PC, this is via a 3.5mm jack socket
HI LEVEL and LO LEVEL 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 “SETTING UP”
