•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
The GECKO® SATELLITE SCM 1820S is world’s first self-powered cardioid handheld condenser
microphone with C.R.I.S.T.A.L.® Audiophile precision, designed to reduce the damage on your mixing
console, microphone tonality change and noises caused by possible unstable +48V C phantom power
supply.
Its pristine audio quality, ultra-low handling noise, and high-fidelity clarity are made possible by
C.R.I.S.T.A.L.® Audiophile back-electret condenser transducer with GECKO®’s state-of-the-art anti-shock
engineering.
Highly recommended for professional vocalists (soloist, choir, broadcast, etc) and instrumentalists (strings,
woodwinds, brass, percussions, orchestra, etc) for both live and recording studio applications.
The GECKO® SATELLITE SCM 1820S redefines the ways how condenser microphones are being built.
Summary of features:
* transformerless circuitry;
* excellent transparency;
* high sensitivity and low self-noise;
* suitable for high SPL environments;
* low output impedance for long distance connection and high EMI resistance;
* wide and smooth frequency response range;
* powered by a single 1.5V AA alkaline battery (up to 16 days of usage time), freeing your mixing console
from possible high impedance loads created by unstable +48V C phantom supply.

CONNECTING AND DISCONNECTING THE MICROPHONE
CONNECTING AND DISCONNECTING THE MICROPHONE
1. Insert the XLR (female) connector on one end of the microphone cable into the microphone. If
necessary, rotate the connector to align the key on the connector and the groove in the microphone.
Push the connector into the microphone until it clicks.
2. Make sure you are connecting to a balanced audio device, be sure to use balanced configuration on
the XLR type connectors. Pin 1 = Ground (Shield), Pin 2 = Positive (Hot), Pin 3 = Negative (Cold).
3. To unplug the connector from the microphone, press the tab before pulling the connector out from
the microphone.
MICROPHONE USE
MICROPHONE USE
1. Set the mixer channel (channel assigned to the SCM 1820S) volume on your mixing console to
minimum position or mute it if it has a mute function, and then connect the GECKO® SATELLITE
SCM 1820S to the balanced XLR input of that channel on your mixing board.
2. Start off referencing by setting the mixing console channel's gain/trim all the way down and its EQ
set flat. With the main stereo output faders set to 0dB position, slowly bring the assigned channel
(connected with the SCM 1820S) fader up while speaking into the SCM 1820S. If you have achieved
your desired volume along the way before hitting that channel's 0dB mark, leave the fader at that
position, if not, continue to bring it up until you reach the channel's 0dB mark and, if it is still not loud
enough, now slowly bring up the gain/trim until you get the desired level while leaving the channel
fader at 0dB. Ensure that your sound reinforcement system's amplification level is set accordingly.
3. To minimize the chance of feedback (a loud howling or squealing noise), ensure that the head of the
microphone is not covered by hand or positioned close to the loudspeaker.
4. For avoid “plosives”, be sure to use a pop filter or windscreen.
5. ue to the high sensitivity of the cartridge, do not drop or apply strong shock to it.
6. To maintain the sensitivity and quality of sound reproduction, avoid exposure to moisture and
extreme temperatures.
7. The GECKO® SATELLITE SCM 1820S can be used for high fidelity instrument and vocal miking, i.e.
lead/solo vocals, backing vocals/choir, speeches, broadcast, strings, woodwinds, brasses,
percussions, orchestra, and also backline amplifiers miking.
