INTRODUCTION
SUB-BASS SYSTEM
Many or most loudspeakers designed to reproduce low bass are specifically designed to emphasize the mid bass. This is the range from 30 to 70 Hertz. We at REL believe this is wrong. All of our designs are true sub bass systems, meaning they are designed to reproduce those very low frequencies that are felt rather than heard. This is because we believe that music is full range, as are sound effects on movies, and we intend our products to reproduce all of these sounds, not a narrow band.
The “Q” range models are equipped to allow you to take full advantage of AC3, Dolby Digital, DTS, MPEG 2 and any other digital sound format that includes a dedicated Low Frequency Effects (LFE) channel.
The dedicated LFE input meets the tough specification laid down for digital 3/2.1 channels, usually known as 5.1. The output is nominally flat from 25Hz - 120hz. It has a dedicated input level control which enables users to set the LFE level independently of the processor. This is important because not all processors offer control over this significant parameter. The LFE channel is typically recorded at 10db higher levels than the other channels.
The “Q” range also has standard speaker level inputs with their own input level control. Uniquely, both the speaker level and the LFE input can be used simultaneously. This means you can set it up for an audiophile sound with your CD’s or other stereo signals and instantly revert to using the Sub-Bass System as the dedicated LFE component when watching movies. This is a feature of real benefit if you wish to play music in stereo mode in the purist audiophile way and in full 5.1 digital mode. True flexibility!
On two models there is a ‘Slam’ and ‘Depth’ selector, 'Slam' mode allows you to choose a higher output level at 50Hz - 240Hz (Q100E) at the expense of maximum bass extension, and 40Hz - 140Hz (Q150E) This is an excellent ‘party’ mode where subtlety and ultimate fidelity is secondary.
Alternatively the standard ‘Depth’ mode 25Hz - 120Hz (Q100E) and 20Hz - 100Hz (Q150E) provides maximum bass extension and is strongly recommended where the highest possible fidelity is demanded. This is ideal for people in pursuit of the absolutely highest fidelity.
See the specification table on page 12 for features of the various models.

CONNECTING UP
Always switch off your system before disconnecting any wires
To increase the versatility of connecting up, the “Q” range have two separate inputs. A Neutrik Speakon socket and a pair of phono sockets. As mentioned, this is to facilitate use with both hi-fi 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.
Method 1 - To Connect to the Power Amplifier Using the Neutrik High Level Input: (See Fig. 1)

NEUTRIK SPEAKON INTERCONNECT
FIG. 1
Fig 1, shows pictorially how to connect to the high level input. Using the supplied Neutrik lead, connect the REL to your existing speaker plugs or to a spare set of speaker terminals. In effect the REL is bi-wired from your power amplifier. However, note that there are only three connections to your power amp. This is deliberate and helps preserve the star earthing of your system (assuming that it has a star earth arrangement). Connect the RED wire to the RED terminal of the RIGHT hand channel speaker terminal of your power amplifier. Connect the YELLOW wire to the RED terminal of the LEFT hand channel speaker terminal of your power amplifier. The BLACK wire is connected to either one of the BLACK speaker terminals of your power amplifier. Do not connect this black wire to both black terminals - this is important as some amplifiers may be damaged by joining the black terminals. Connect the Neutrik plug to the high level input on the REL.
