Introduction

Thank you for purchasing the Earthquake Sound SM6BT professional active studio monitor. Regarding studio monitors, one would desire accurate audio reproduction, sound clarity, transparent performance with low distortion, and exceptional imaging. With those characteristics in mind, every Earthquake SM6BT studio monitor component has been carefully selected to deliver on those characteristics demanded by audiophiles and professionals worldwide.

Equipped with a bi-amplified class AB amplifier, the SM6BT studio monitor accepts unbalanced (RCA) and balanced (XLR/TRS combo jack) inputs as well as Bluetooth® v5.3 True Wireless Stereo (TWS) connectivity for general everyday audio enjoyment. If extra bass is needed, a subwoofer output is available to connect a powered subwoofer for a complete 2.1 audio system. The SM6BT also features a high frequency trim adjustment control to tailor the sound to your listening preferences.

The drivers installed in each SM6BT monitor feature a stiff and low-mass 6-inch carbon fiber cone woofer for extremely low harmonic distortion and a 2-inch wide band ribbon tweeter for ultra-clear, detailed, and dynamic treble output. Integrating these components ensures balance, transparency, and neutral audio reproduction. Discover details in music and movies that you never thought were possible with the SM6BT.

Troubleshooting The SM6BT Monitor

The Front LED Does Not Light Up

• Inspect the power cable. Never use one that has been altered in any way.
• Verify the AC power outlet is active and supplying the appropriate AC voltage.
• Verify the monitor’s AC selector is set to the proper setting with the correct fuse installed (refer to page 7 for fuse rating and how to access the fuse compartment). Make sure that the fuse is not blown.
• Verify that the power cord is securely plugged into the unit and the power AC outlet.
• Check that the monitor’s POWER switch is ON.
• Check to ensure the LED ON/OFF selector is in the correct position.
• If the fuse(s) blow once the monitor is switched on, please contact Earthquake Sound Technical Support at (1-510-732-1000 or tech@earthquakesound.com)..)

The Front LED Lights Up But There Is No Sound

• Perform the troubleshooting steps above before proceeding with the next steps.
• Verify that all devices plugged into the same AC outlet are still working.
• Make sure that the signal source (e.g., mixing console, DJ workstation, etc.) is at a level that can properly send a signal to the monitor(s).
• Make sure the VOLUME knob (system gain potentiometer) is turned fully clockwise to +6dB.
• Ensure the audio source cable is firmly plugged into both the source output and the monitor input.
• If operating two monitors and this problem only occurs on one of the units, exchange the audio input cable from the non-working unit to the working one to determine where the problem lies (the monitor, the cable, or elsewhere).
• If the problem persists, please contact Earthquake Sound technical service. The Monitor Suddenly Stops Working

Turn the SM6BT monitor off.

• Perform the troubleshooting steps above before proceeding with the next steps.
• Carefully check if the amplifier’s back plate is hot. It is possible that the protection circuitry was triggered and shut down because it ran at its highest power output for an extended time. Turn the monitor power off and keep it off for at least 30 minutes to allow the amplifier to cool down before turning it back on.
• Increase the volume to check for normal operation.

Main Power Switch
This switch controls the AC power going to the SM6BT monitor. We suggest keeping the switch in the OFF position when the monitor is not being used for an extended period of time.
**

110V/220V Selector Switch
The SM6BT monitors can operate in a 110-120V or 220- 240V environment. Simply slide the selector to the required power input setting and replace the fuse to the proper rating prior to connecting the monitors to a power source.
USE OF IMPROPER VOLTAGE MAY RESULT IN HAZARDOUS CONDITIONS AND/OR DAMAGE TO THE
MONITOR COMPONENTS THAT ARE NOT COVERED BY THE FACTORY WARRANTY. FOR YOUR SAFETY, PLEASE MAKE SURE THAT THE MONITOR IS NOT CONNECTED TO ANY POWER SOURCE PRIOR TO ACCESSING THE AC SELECTOR AND FUSE COMPARTMENT.
AC Power Inlet with Fuse Holder
This AC line connector is fused to protect the amplifier from unwanted power surges. Be sure to use the proper fuse rating when replacing the existing fuse: ø5 x 20mm 2A/250V UL/VDE slow blow tube fuse To access the fuse compartment, simply unplug the power cable from the monitor, place a flat-head screw driver in the small notch and pry it open as illustrated
Subwoofer Output**
This unbalanced RCA output is used for providing signal to a powered subwoofer if needed.

ON=L CH
OFF=R CH
TWS Status LED Indicator
This LED is the True Wireless Stereo (TWS) master speaker and slave speaker indicator. When TWS pairing succeeds, the software automatically assigns the master and slave speakers. Usually, the master speaker is the left channel, and the slave speaker is the right channel.

True Wireless Stereo (TWS)
This button is used to put the two SM6BT monitors in True Wireless Stereo pairing mode. See page #11 for TWS pairing procedure.

Input Selector Switch
This is a 2-way selector switch that allows you to select between input methods. Sliding the switch up enables Bluetooth® and sliding it down enables the unbalanced or balanced inputs. When using the Bluetooth® input, make sure that this switch is set to the correct position before pairing to any Bluetooth® enabled devices.

LED ON/OFF Selector Switch
This is a 2-way selector switch allows for the user to turn the front mounted LED indicator light on or off.

Level Adjustment Knob
This level knob controls the monitor’s input sensitivity. Typically, you would want to set the knob to the maximum setting (+6dB), adjust the source’s output level and then use the level knob to match the left and right monitors.

HF Trim Knob
This high frequency adjustment knob is factory set at 0dB or flat. Simply adjust this knob accordingly to tailor the sound to your listening preferences.

SM6BT Monitor Placement

Proper placement of your SM6BT monitors is a crucial step in making sure that they perform at their best.
Studio/Stereo Application
Earthquake suggests placing the monitors within the front 1/3 of the room, about 3 to 5 feet away from each other and directed at a 60 degree angle towards your listening position.

SM6BT Monitor Surround Sound Application

Begin by placing the center channel monitor right before your listening position. Then place the front left and right monitors at an equal distance and about 25 to 30-degree angle from the center. The three front monitors (left, center, and right) should form a slight arc, as shown below. Continue placing the rear monitors at an equal distance from the listening position and angled about 90 to 110 degrees from the center, as illustrated below.
