Use the following knobs and sliders on the rear panel:

• MASTER VOLUME (6): Regulates the overall output volume of the speaker. Turn clockwise to increase volume.
• MIC LEVEL (17): Regulates the output volume for the microphone connected to the MIC XLR/1/4” INPUT (20). Turn clockwise to increase volume.
• INSTRUMENT INPUT VOLUME (16): Regulates the volume for the source connected to the 1/4” INSTRUMENT INPUT (19). Turn clockwise to increase volume.
• LINE LEVEL INPUT VOLUME (18): Regulates the output signal level of the source connected to the BALANCED RCA LINE INPUT (21). Turn clockwise to increase volume.
• BLUETOOTH VOLUME CONTROL (7): Regulates the Bluetooth output volume. Turn clockwise to increase volume.
• ECHO LEVEL (8): Regulates the amount of Echo effect applied to the Mic Channel (inputs 19 and 20).
• EQ Sliders (5): These 5 sliders (Low, Low/Mid, Mid, High/Mid, High) adjust the amount of bass, mids, and treble applied to the output signal. Each slider provides up to +12dB of boost or -12dB of cut.

(Numbers in parentheses refer to the diagram labels in the PDF.)
Important: Always set gain controls to their lowest level during initial power-up to prevent speaker damage.

Use the input jacks on the rear panel:

• MIC XLR/1/4” INPUT (20): Accepts either an XLR or 1/4″ plug from a microphone. The volume is controlled by the MIC LEVEL knob (17).
• 1/4” INSTRUMENT INPUT (19): Input jack specifically for instruments like guitars. The volume is controlled by the INSTRUMENT INPUT VOLUME knob (16).
• BALANCED RCA LINE INPUT (21): Designed to accept a line input signal from a mixer or other line-level device (like CD players, tape machines) using RCA cables. The volume is controlled by the LINE LEVEL INPUT VOLUME knob (18). For cable lengths exceeding 15 feet, using balanced connections (if available from the source device, typically via XLR or TRS, which this input does not directly support but the principle applies to reducing noise) is recommended to minimize signal loss, although this input is RCA. Ensure only line-level devices are connected here.

(Numbers in parentheses refer to the diagram labels in the PDF.)

Use the 1/4” OUTPUT (9) jack on the rear panel to link the audio signal to another active speaker or amplifier system.

The ELS GO 15BT can be powered in three ways:

1. Internal Battery: The speaker has a built-in rechargeable battery.
2. AC Power: Connect the included detachable IEC power cord to the MAIN POWER INLET (12) on the rear panel and plug it into a wall outlet matching the voltage specified on the unit (AC 115v-230v, 50/60Hz). Use only the supplied polarized AC power cord and ensure the ground prong is intact. The cord is designed to fit only one way.
3. External DC Power: Connect a compatible 12V battery source (like a car battery) to the DC BATTERY BINDING POST CONNECTIONS (10), observing correct polarity (+ to +, – to -).

Use the MAIN POWER SWITCH (11) to turn the speaker ON or OFF. Always make sure all connections are made before applying power. Turn the mixer/sources on first and off last to avoid damaging pops.

To recharge the internal battery, plug the supplied power cord into the MAIN POWER INLET (12) on the rear of the unit and plug the other end into a matching power outlet. The CHARGING INDICATOR LED (15) will glow red while the battery is charging. When the battery reaches full charge, the LED indicator will glow green. It takes approximately 8 hours to reach a full charge.

• POWER LED (13): Indicates that the speaker’s main power is switched ON.
• PEAK INDICATOR (14): Lights up if the audio signal is clipping (distorting). If this LED lights frequently, lower the volume level of the input source or the master volume until the LED only blinks occasionally along with the bass beat, or not at all.
• CHARGING INDICATOR (15): Glows RED when the internal battery is charging. Glows GREEN when the battery has reached full charge.

(Numbers in parentheses refer to the diagram labels in the PDF.)

The remote control operates the MP3 player functions from a distance of up to 3 meters. Point the remote towards the speaker’s MP3 player section.

• 1. POWER: Turns the MP3 player module on/off.
• 2. MODE: Selects the source (USB/SD/BLUETOOTH).
• 3. FORWARD SCAN (SCAN+): Functionality may vary; often used for seeking within tracks or scanning radio stations if applicable (not explicitly stated for MP3).
• 4. VOLUME +: Increases volume.
• 5. NEXT (CH+): Skips to the next track.
• 6. PLAY/PAUSE BUTTON: Toggles between play and pause.
• 7. VOLUME -: Decreases volume.
• 8. EQ SELECT: Selects preset equalizer settings for the MP3 player.
• 9. TRACK NUMBERS (0-9): Allows direct selection of tracks by number (if supported by the media).
• 10. RANDOM (RAN): Toggles random/shuffle playback mode.
• 11. PREVIOUS (CH-): Skips to the previous track.
• 12. REVERSE SCAN (SCAN-): Functionality may vary; often used for seeking within tracks or scanning radio stations if applicable.

(Numbers refer to the labels on the remote diagram in the PDF.)

Connect the line-level output (often RCA or XLR/TRS) from your mixer or DJ controller to the corresponding line input on the ELS GO 15BT. The PDF shows an example using an RCA-to-RCA cable connected from the mixer’s output to the speaker’s BALANCED RCA LINE INPUT (21). Adjust the volume using the LINE LEVEL INPUT VOLUME (18) knob on the speaker and the output controls on your source device.

The ELS GO 15BT has a pole mount socket located on the bottom. This allows you to secure the speaker onto a standard speaker tripod stand, such as the American Audio® SPS-1B. When pole mounting, always follow these guidelines:

• Ensure the stand is designed to support the weight of the speaker (25 lbs / 12 kgs).
• In outdoor situations prone to wind, use sandbags or other weights on the tripod base for additional stability to reduce the risk of tipping.
• Do not stack speakers on top of each other when mounting on a tripod. Only mount one speaker per tripod at a time.
• Position the tripod legs away from foot traffic paths.
• Extend the tripod legs fully to their designated stable position to prevent accidental tipping.
• Observe and follow all safety guidelines and regulations specified by the tripod stand’s manufacturer.
• Ensure the tripod is situated on a flat, level, and stable surface.
• Always tighten all locking mechanisms on the tripod stand securely.

The speaker also includes rigging points on the top, bottom, and rear for permanent or flight installations, though specific instructions for using these are not detailed in the provided excerpt. Consult a professional for rigging applications.

There are no user-serviceable parts inside the speaker. Do not attempt any repairs yourself unless instructed by an authorized American Audio technician, as doing so will void the manufacturer’s warranty. Service may be required if:

• The power-supply cord or plug is damaged.
• Liquid has been spilled, or objects have fallen into the product.
• The product has been exposed to rain or water.
• The product does not operate normally according to the operating instructions.
• The product has been dropped or damaged in any way.
• The product exhibits a distinct change in performance.
• The terminal/cross-over plate has been damaged.

If your speaker requires service, contact American Audio® customer support to obtain a Return Authorization (R.A.) number. The R.A. number must be clearly written on the outside of the return package. You must include a brief description of the problem and the R.A. number on a piece of paper inside the shipping container. If the unit is under warranty, you must provide a copy of your proof of purchase invoice. All returned service items must be freight pre-paid. Packages returned without a visible R.A. number will be returned to the shipper unopened.

• Hearing Damage: The speaker can produce Sound Pressure Levels (SPL) high enough to cause hearing damage. Use care with prolonged exposure to SPLs above 85dB.
• Adult Use Only: Keep out of the reach of children.
• Power: Turn off power before making connections. Use a power cord matching the manufacturer’s specifications and ensure the ground pin is intact. Disconnect from main power before making connections or during long periods of non-use. Ensure the local power outlet matches the required voltage.
• Environment: Intended for indoor use only; outdoor use voids the warranty. Do not expose to rain or moisture. Keep away from heat sources (radiators, stoves, amplifiers).
• Operation: Keep the grille attached during use. Mount securely and stably. Route power cords away from foot traffic and avoid pinching. Do not block ventilation openings. Clean only with a soft dry cloth. Do not spill liquids onto the speaker.
• Connections: Use appropriate cables. For the RCA Line Input, use balanced cables for runs over 15 feet if possible (though the input itself is RCA).
• Gain Levels: Start with gain controls at the lowest level during power-up.
• Servicing: Do not attempt service beyond what is described in the manual. Refer servicing to qualified personnel.
