IMPORTANT SAFEGUARDS

1. Read all of these instructions.

2. Save these instructions for future use.

3. Unplug from the wall socket before cleaning. Do not use liquid cleaners or aerosol cleaners. Use a damp cloth for cleaning.

4. Do not use near water.

5. Do not place on a stand or table, it may fall causing injury to a child or adult, and damage to the unit.

6. The unit should only be operated from the power source indicated on the panel of the amplifier.

7. Only use the power cord supplied.

8. Do not allow anything to rest on the power cord. Position the power cord such that it can not be walked on.

9. For added protection during a lightening storm, or when not in use for long periods of time, unplug it from the wall socket.

10. Never spill any kind of liquid on the unit.

11. Do not attempt to service the unit yourself, as removing the amplifier may expose you to dangerous voltages. Refer all servicing to your dealer.

12. Unplug the unit from the wall socket and refer servicing to your dealer under the following conditions:

a. When the power cord or plug is damaged. b. If liquid has been spilled onto the unit. c. If the unit does not operate properly by following the operating instructions. d. If the unit has been dropped and damaged. e. When the unit exhibits a drastic change in performance.

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.

If for any reason the plug is cut off it must NOT be re used. Please dispose of any such plug safely. There is a danger of electric shock if the cut off plug is inserted into a mains socket.

IMPORTANT

The wires in the mains lead are coloured in accordance with the following code:

Green and Yellow - Earth Blue - Neutral Brown - Live

As the colours of the wires in the mains lead may not correspond with the markings identifying the terminals in the replacement mains plug, proceed as follows:

- The wire coloured Green and Yellow must be connected to the terminal marked with the letter "E" or with the earth symbol

- The wire coloured Blue must be connected to the terminal marked with the letter "N"

- The wire coloured Brown must be connected to the terminal marked with the letter “L"

This product is CE marked and has been tested to ensure it satisfies all relevant standards.

It satisfies all relevant standards for Conducted Emissions, Radiated Emissions, Susceptibility and Immunity.

It also complies with the requirements relating to class II construction detailed in clauses 9 & 10 of BS EN 60065 1994

It also satisfies all relevant safety tests for consumer use provided it is used within the guidelines of this manual.

INTRODUCTION TO ‘Q’ RANGE SUB BASS SYSTEMS

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 SubBass 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, (Q150E and QUAKE). 'Slam' mode allows you to choose a higher output level at 40Hz - 150Hz at the expense of maximum bass extension. This is an excellent ‘party’ mode where subtlety and ultimate fidelity is secondary.

Alternatively the standard ‘Depth’ mode 20Hz - 100Hz 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 pages 18 and 19 for features of the various models.
