REL Acoustics ‘Q’ range User manual WELCOME Thank you for buying a REL “Q” range Sub-Bass system. Our “Q” range is carefully hand built using the finest materials available and is designed for maximum performance. This manual contains important safety information as well as helpful advice and should be carefully studied before connecting up. WORLD WIDE WARRANTY In addition to any local Warranty, REL offer a 3-year conditional Worldwide Warranty to the end user.
REL Acoustics ‘Q’ range User manual DESIGN SAFETY This apparatus is designed to Class II specification and is double insulated, therefore it does not require to be earthed. This apparatus is supplied with a fitted mains plug. For UK operation a 5 Amp fuse is fitted in the plug. Should the fuse need to be replaced use a similar rated fuse approved to ASTA or BSI 362. Do not use without the fuse cover in place. Replacement fuse covers are available from your dealer.

REL Acoustics ‘Q’ range User manual 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.
REL Acoustics ‘Q’ range User manual To connect to the power amplifier using the UNBALANCED 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 (counter-clockwise in the US) quarter turn and withdraw.
REL Acoustics ‘Q’ range User manual To connect to the amplifier/processor using the phono to phono low level interconnect Supplied Phono to Phono Interconnect. To sub/LFE output of Amplifier/Processor Sub Low Level Input. (One phono Only on Quake and Q108) Two low level inputs are provided, 0dB and +12dB, One only on Quake and Q108 at +12dB Connect as shown above. Although a twin phono to phono interconnect is supplied, only one core need be used, either the red or the black.
REL Acoustics ‘Q’ range User manual MODE SELECTOR (NOT APPLICABLE TO Q108) POSITION 1 2 3 4 SOURCE LINE LFE LINE LFE PHASE 0 0 180 DEG 180 DEG The mode switch is a dual function control, it can reverse the phase for both high level and low level inputs and it can bypass the internal filter/roll off. Phase reversal is rarely needed but can be useful as explained in “SETTING UP” . MODE SWITCH. Used to set phase* and to bypass crossover for Low Level input**.
REL Acoustics ‘Q’ range User manual REL Set-Up Made Simple REL products are not traditional subwoofers, but true sub-bass systems. A REL is designed to augment the performance of “full range” speaker systems, to provide linear response down to below 12 Hz (Studio III, -6 dB down at 9 Hz). Therefore, for the moment, set aside everything you’ve been taught about subwoofers and how they are integrated into a stereo or theatre system. REL sub bass systems set-up and positioning differs from other subwoofers.
REL Acoustics ‘Q’ range User manual Positioning The optimal position for a REL is in one of the corners behind the main speakers. This position provides 9 dB of mechanical amplification and allows for the most linear true low bass wave launch, owing to the ability to tune the sub to the axial node of the room, or longest throw distance. The Process To begin the set-up process, choose a piece of music that has a repetitive bass line that is very low in frequency.
REL Acoustics ‘Q’ range User manual Note: As the Q-series crossover adjustment uses a single variable control, use the closest correlating position to any of the crossover settings noted above for ST series models. Ultimately, as with the click stops of the ST range, simply bring gain and then crossover up until excess output is achieved, then back down a soft-click or two.
REL Acoustics ‘Q’ range User manual REL Set-Up Made Simpler Connecting High-level connection, using the enclosed cable, is always the first choice. The standard high level hook up procedure is: attach the red wire to the amplifier’s right positive speaker output terminal; attach the yellow wire to the amplifier’s left positive speaker output terminal; attach the black wire to which ever of the amplifier’s ground output terminals is convenient; plug the connector into the “Hi Level” input.
REL Acoustics ‘Q’ range User manual RUNNING IN Care taken over running in will be rewarded by many years of pleasurable use. Both the electronics and the drive unit will benefit from an initial period of carefully controlled use. Possible damage may be sustained by running in the unit at too high a volume setting over an extended period. On the other hand, by taking a little care over this initial period, about 24 hours of actual use, a longer life with a higher potential eventual performance is assured.
REL Acoustics ‘Q’ range User manual TECHNICAL The ground switch (if fitted) provides a physical mains earth connection to the Sub Bass System if required. When the unit is connected up and switched on, listen for any ‘hum’ from it, if ‘hum’ is present then change the ground switch position from in to out (on to off for US market) or vice versa. In the in (on) position the mains earth is connected, in the out (off) position the mains earth is disconnected.
REL Acoustics ‘Q’ range User manual POWER SAVING EFFICIENCY All REL Sub-Bass Systems are designed for maximum power efficiency, both when passing a signal through to its resultant output sound into the room and also when silent. REL circuitry is designed for “power starvation” operation under no signal conditions.
