SAFETY INSTRUCTIONS:

• To reduce the risk of electrical shock, do not remove covers. No user-serviceable parts inside. Please refer servicing to qualified personnel.

•

To reduce the risk of electrical shock or fire, do not expose the equipment to rain or moisture.

• Do not impose unnecessary stress on your equipment (i.e. placing heavy objects on it, over screwing its mounting, etc).

• Read and keep the instruction manuals in a safe place for future references.

• Do not attempt to clean the equipment with chemical solvents as this may damage the finish. Clean only with a dry cloth.

• Do not block any ventilation openings.

• Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus that produce heat.

• Do not defeat the purpose of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. A grounding type plug has two blades and a third grounding prong. The wide blade or the grounding prong is provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for the replacement of the obsolete outlet.

• Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the point where they exit from the apparatus.

• Unplug the apparatus during lightning storms or when it is not in use for a long period of time.

• Use only attachments/accessories specified by the manufacturer.

• Always shut down power supply when not in use to save energy and for a prolonged lifespan.

• Exposure to extremely high noise levels may cause permanent hearing loss. Individuals vary considerably in susceptibility to noise-induced hearing loss, but nearly everyone will lose some hearing if exposed to sufficiently intense noise for a period of time. The U.S. Government’s Occupational Safety and Health Administration (OSHA) and the Singapore Workplace Safety and Health Council (WSHC) has specified the permissible noise level exposures shown in the following chart. According to OSHA and WSHC, any exposure in excess of these permissible limits could result in some hearing loss. To ensure against potentially dangerous exposure to high sound pressure levels, it is recommended that all persons exposed to equipment capable of producing high sound pressure levels use hearing protectors while the equipment is in operation. Earplugs or protectors in the ear canals or over the ears must be worn when operating the equipment in order to prevent permanent hearing loss if exposure is in excess of the limits set forth here:

Engineered to complement the REVELATION series loudspeakers, the innovative GECKO® REVELATION

SR 618WA 18” active C.R.I.S.T.A.L.® Audiophile long-throw subwoofer incorporates a very powerful yet versatile built-in C.R.I.S.T.A.L.® Audiophile Class-H amplifier, enabling consistent low-frequency sound output as well as simplicity of use. Its wide low-frequency spectrum extension ensures perfect natural reproduction of any bass playback.

Incorporating state-of-the-art dynamic speaker cone with superb wide horizontal area coverage of 360º, it is guaranteed to cover all floor spaces of concern, and this advantage translates to cost savings as fewer subwoofer units will be required for any given venue.

The GECKO® REVELATION SR 618WA 18” active C.R.I.S.T.A.L.® Audiophile long-throw subwoofer is housed in a weather-resistant birch ply cabinet. It is built to withstand the rigorous demands of any concert touring and to take on the hard knocks of demanding stage usage.

6. OUTPUTS

Two balanced, male XLR type OUTPUT connectors are provided to loop-thru signal from one REVELATION

SR 618WA to another REVELATION SR 618WA, active loudspeaker or power amplifier.

7. LED INDICATORS

CLIP (RED LED)

Shows OUTPUT capability is being exceeded, with clipping distortion.

SIGNAL (GREEN LED)

Shows signal is present on the REVELATION SR 618WA.

POWER (AMBER LED)

Illuminates when the main power supply is active on the REVELATION SR 618WA.

8. PHASE SWITCH

Compensates for having REVELATION SR 618WA and main loudspeakers in different locations. Ideally,

REVELATION SR 618WA sound should reach the listening position at the same time as sound from the main loudspeakers. However, if the distance from the listening position to the REVELATION SR 618WA, and from the listening position to the main loudspeakers differ, the sound from each will reach your ears at different times. The PHASE SWITCH, when switched to “REVERSE”, delays the signal by 180 degrees, so the REVELATION SR 618WA output will blend into that of the main loudspeakers. At the listening position, listen to the mid-bass output. If it sounds weak, set PHASE SWITCH back to “NORMAL”.

9. HF ROLLOFF FREQUENCY CONTROL

This crossover control allows you to adjust the upper limit of the REVELATION SR 618WA’s response from

30Hz to 160Hz. The REVELATION SR 618WA’s response will begin rolling off above the set frequency. Set the crossover frequency to the lowest frequency response rating of the main loudspeakers.

10. GAIN CONTROL

This knob is used to regulate the output level of the REVELATION SR 618WA. Use this to set the balance between the main loudspeakers and the REVELATION SR 618WA.

11. AC POWER CORD RECEPTACLE

The

REVELATION SR 618WA

comes with a detachable power cord. This cord must be attached to the

IEC receptacle on the REVELATION SR 618WA

before the cord is plugged into the AC wall socket.

12. VOLTAGE SELECTOR

This switch is pre-set at the factory for the proper local voltage, so there is no need to change the switch setting. For 110V operation, set the VOLTAGE SELECTOR to 110V.

WARNING:

Always ensure you have the appropriate voltage rating selected on your

REVELATION SR 618WA before plugging into an AC outlet. Connection to an inappropriate power source may result in fire or electric shock, and extensive damage which is not covered by the warranty.

13. REPLACEABLE FUSE

Protects system from overload, replace with fuse rating as indicated on the REVELATION SR 618WA's amplifier panel's fuse location.

14. POWER SWITCH

Push in on the top [I] of the rocker switch to apply AC mains power to the REVELATION SR 618WA. Push in on the bottom [O] of the rocker switch to turn the REVELATION SR 618WA OFF.

To connect the REVELATION SR 618WA to your sound system, refer to the following steps:

1. Turn OFF all equipment before making any connections.

2. Place the REVELATION SR 618WA approximately 4-5 feet, either to the left or to the right of your main loudspeakers (with the exceptions if you are using REVELATION series loudspeakers as main loudspeakers, whereby you can pole-mount them above the REVELATION SR 618WA enclosures).

3. For purest sound quality, make connections using only premium quality audio cables (i.e. GECKO®

TRUTH T2, GECKO® TRUTH T3AL), connectors (i.e. GECKO® OLYMPIAN and GECKO®

AUDIOPHILE connectors), amplifiers (i.e. GECKO® GENESIS ELEGANCE and DEFINITY AUDIO® amplifiers), and mixing consoles (i.e. GECKO® EXODUS series mixing consoles) according to your requirements.

4. Turn ON all equipment after making connections. Alternatively, you could set up the power-up and down sequence of your system using the GECKO® GALILEE CLASSIC PSC 8330 power sequencer for optimum protection.
