•Use only attachments / accessories specified by the manufacturer.
•Always shut down power supply when not in use to save energy and for 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) has specified the permissible noise level exposures shown in the
following chart. According to OSHA, 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. Ear plugs 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:

INTRODUCTION
INTRODUCTION
Engineered to complement the REVELATION series full-range systems, the innovative GECKO®
REVELATION SR 618WA 18” active audiophile long-throw subwoofer incorporates a very powerful yet
versatile built-in C.R.I.S.T.A.L.® Audiophile Class H amplifier, enabling robust audiophile output as well as
simplicity of use. Its wide low frequency spectrum coverage ensures perfect natural reproduction of any bass
playback.
Incorporating state-of-the-art dynamic speaker cones with superb wide horizontal area coverage of 90º, 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 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.

SUBWOOFER ELEMENTS
SUBWOOFER ELEMENTS
1. GRILLE

wear resistant black paint to ensure best resonance and durability.
3. RECESSED HANDLE
To ease the carrying of the REVELATION SR 618WA.

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 speaker 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 main power supply is active on the REVELATION SR 618WA.
8. PHASE SWITCH
Compensates for having REVELATION SR 618WA and main speakers in different locations. Ideally,
REVELATION SR 618WA sound should reach the listening position at the same time as sound from the main
speakers. However, if the distance from the listening position to the REVELATION SR 618WA, and from the
listening position to the main speakers 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 speakers. 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 speakers.
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 speakers and the REVELATION SR 618WA.
11. AC POWER CORD RECEPTACLE
The REVELATION SR 618WA is provided 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 in to 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.

panel at 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.
MAKING CONNECTIONS
MAKING CONNECTIONS
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 speakers (with the exceptions if you are using REVELATION series full-range systems as main
speakers, whereby you can pole-mount them above the REVELATION SR 618WA enclosures).
3. For purest of sound, make connections using only quality audio cables (i.e. GECKO® TRUTH
T3AL), and connectors (i.e. GECKO® OLYMPIAN connectors) according to your requirements.
4. Turn ON all equipment after making connections.
