ENGLISH // DESCRIPTION

The Gemini GSYS-4000 Dual 12" Bluetooth Party System is all you need to bring the ultimate nightclub experience to any room or event! With 6000 watts of power, the GSYS-4000 makes its dual 12" woofers and twin 4" tweeters sound amazing at any volume. The DJ style interface makes controlling your music easy and intuitive, and the built-in lights create a party atmosphere. With inputs for microphone and guitar, karaoke and even full-on live performance is as easy as turning a knob.

CONNECTION DIAGRAM

POWERING ON AND STANDBY

There are 2 switches that control power for the GSYS-4000. At the rear of the unit next to the AC power input, there is a switch that can be used to disconnect the unit from mains power completely. However, if you just want to suspend operations but don't need to completely disconnect power, you can use the STANDBY button located on the top of the unit.

The GSYS-4000 can tune the overall sound to suit your needs. Maybe you need a little more bass in the track, or more treble to bring out a singer's voice. The easiest way to contour the sound is to use the BASS and TREBLE knobs located on the top of the unit. Turning the BASS knob controls the low frequencies in the track, while the TREBLE knob controls the high frequencies. BASS and TREBLE controls are also

available on the unit's remote control.

The remote also has an EQ button, which acts independently from the BASS and TREBLE knobs. Pressing the EQ button cycles through 5 presets EQ curves (POP/ ROCK/JAZZ/NORMAL/CLASSICAL). Please note that you can also use the EQ knobs to further tailor the sound.

USING BLUETOOTH

The GSYS-4000 can connect wirelessly to your external music source (for example, your phone or tablet). To enable this feature, you must first pair your external device to the GSYS-4000.

PAIRING

Turn the GSYS-4000 on and press the MODE button until the display shows the word "BLUE". This is Bluetooth mode. If no Bluetooth device is currently paired, the BT icon will flash to let you know the GSYS-4000 is in SEARCH mode.

On your portable device, make sure Bluetooth is turned on. Search through the list of available Bluetooth devices for "GSYS-4000" and connect to it.

You should now be connected to the GSYS-4000. Any audio from your portable device should now play through the Gemini GSYS-4000 speaker.

You can control basic functions (like play/pause, volume, and previous/next track) with the buttons on the top of the GSYS-4000 (as well as with your media player). You should only ever have to pair with the GSYS-4000 once. It will remember paired devices and connect to them automatically after first pairing.

USING THE FM RADIO

The GSYS-4000 is equipped with an FM radio receiver and intelligent scanning capability, making finding and storing local stations fast and easy.

Turn the GSYS-4000 on and press the MODE button until the display

shows the word "FM". This is RADIO mode. Be sure to also extend the antenna on the back of the unit to increase the reception.

SCANNING FOR STATIONS

At first, there won't be any stations stored in the unit. To begin a station scan, press and hold the PLAY button. This will begin the scanning process. When the GSYS-4000 finds a strong station, it will store it as a preset.

Once the scan is complete, you can pick between the available stored preset by pressing the I<< and >>I buttons. The preset number and station frequency will appear in the display.

USB AND SD CARD PLAYBACK

It is possible to play music from either a USB Flash drive or an SD card without the need for an external device (like a phone or computer). Please note that supported file types are ".mp3" and ".wma".

Turn the GSYS-4000 on and insert either a USB or SD card with compatible music on it.

If the GSYS-4000 does not automatically switch to USB mode, press the MODE button until the display shows the word "USB" or "SD".

You will now be able to play music from your USB or SD device. Basic controls (for instance play/ pause, next, and previous track) allow you to change songs, etc. You can use the REC PLAY button on the remote to play back any previous recordings stored on the USB or SD card.

USING THE AUX AND GUITAR INPUTS

The GSYS-4000 lets you perform for an audience with the ability to mix external sources. Turn the GSYS-4000 on and make sure the volumes are all

down. Insert the included Mic and/or a Guitar into the inputs and make sure they are switched on. Press the MODE button until the display shows the word "AUX".

You will now be able to play live audio from external devices like a microphone and guitar. Full control over volume is available with the

left platter (Mic Volume) and top left knob (Guitar Volume). You may also use the Echo knob to add in an echo effect.

USB RECORDING

The Gemini GSYS-4000 can record your live performance. Please note that recording is only enabled when a USB drive and mic are attached. To begin recording, unit can be in either AUX, USB, or FM mode.

• In AUX mode, audio from mic and AUX input will be recorded.
  • In USB mode, mic input will be recorded.
  • In FM mode, FM radio audio will be recorded.

Insert your USB drive. The GSYS-4000 will create a directory called "RECORD" that it will put your recordings.

Press the RECORD button to begin recording. You will see the display change to a time readout (starting at 00:01) showing elapsed recording time.

You may now begin your recording. When you are finished recording, press the RECORD button again to stop. Please note that while unit is in recording mode, audio through the speakers is muted. You can use the included remote control to access your new recordings, or you can remove your USB drive and play them on any computer. REC PLAY lets you play back recordings you've created, R.DEL allows you to delete the currently selected recording.

CONTROLLING THE LIGHTING

There are 2 buttons on the remote that control the GSYS-4000 lighting. The LIGHT button turns the lights on or off. The RGB button allows you to change the lighting color, cycling through RED, GREEN, and BLUE. Please note that pressing the LIGHT button is how you return the lights to their normal multi-color, sound active mode. Lighting will change on the speakers shown in the diagram. Other lighting on the unit (for instance, the display color, button backlighting, etc.) will not change.
