Dual MEQ15BT Wireless Smart EQ Processor Owner’s Manual
FCC ID : GJW-SBT504
IC ID : 4038A-SBT504
Preparation
Please read the entire manual before installation.
It is highly recommended that your Smart EQ be installed by a professional
installer or an authorized dealer due to the highly technical nature of this
product.
Before Installing
- Disconnect the negative battery terminal (consult a qualified technician for instructions if necessary).
- Avoid subjecting Smart EQ to dust, dirt, excessive vibrations, or high temperature (i.e. direct sunlight).
- Use extreme caution when drilling holes to avoid damaging fuel lines or existing boats wiring.
Mounting Location
- To function properly, Smart EQ has to be installed between the head unit and the amplifier.
- It is recommended to install Smart EQ near the amplifier to minimize interference and facilitate the installation.
- Do not install the Smart EQ where it may be exposed to moisture.
TYPICAL MOUNTING METHOD
Connection Descriptions
Power Wire (+12V)
- Disconnect the negative battery terminal before processing. Consult a qualified technician if necessary.
- Plan out the wire routing before cutting any wires to length. Begin by routing the power wire from the battery to Smart EQ. The power wire can be pigtailed from the amplifier.
- Always use a grommet when running wires through any metal openings. Avoid running the power wire near the existing wiring to prevent noises from entering the audio system.
- Use extreme caution when drilling holes to avoid damaging fuel lines or existing boats wiring.
Ground Wire (GND)
- Choose an unpainted section of metal and clean the section of any dirt or grease before installing the ground connection.
- The Smart EQ can share the grounding point with the amplifier.
ACC Wire (+12V)
- ACC wire has to be connected to the accessory line.
Remote Turn-on Wire (REM)
- The remote turn-on wire connects to the remote turn-on terminal on the amplifier. This is used to turn the amplifier on when a signal is detected by Smart EQ.
Input/Output
- The Smart EQ’s input connects to the head unit’s low level (RCA) or high level (speaker wire) outputs.
- Because the low level input (RCA) delivers the best performance, always connect to Smart EQ via RCA when possible. Only use the high level input when low level input is unavailable.
- Smart EQ’s output (RCA) connects to the amplifier’s low level input (RCA).
CAUTION
- Do not use both low and high level inputs. Connect Smart EQ to only one input source at a time.
- Keep the low level input away from any power wires to avoid engine-induced noise.

Typical Wire Routing
Input Connections
The input source for Smart EQ can be the head unit, via RCA or high level inputs, or a paired and connected Bluetooth media device.
Note: The default setting for the input source is the head unit. To change the source, use the Smart EQ app on your mobile device (see ‘Using Application’ section on page 8).
Low Level Input (RCA)
- Low level input (RCA) is preferred for the best performance. Using a twisted pair construction RCA cable will minimize noise.
High Level Input (head unit speaker wires)
- High level input should be used only when RCA outputs are not available on the head unit. To use the high level input, connect the head unit speaker output to Smart EQ’s high level input connector as shown.
Note: Ground wire is used for voltage mismatch between the source unit and the amplifiers. If there is engine noise when using high level input without ground, connect the ground, and vice versa.
Note: Do not connect both low and high level inputs at the same time.
Output Connections
Amplifier Connection
-
Remote Turn-on/off
The remote output (REM OUT) of Smart EQ has to connect to the remote input (REM IN) terminal of an amplifier as below. When connected, this signal controls the power to the amplifier and turns it on if an audio signal is detected by Smart EQ.
-
Line Output (RCA)
The RCA Front/Rear line output should connect to a multi-channel amplifier that controls your full range speakers in the boat.
-
Subwoofer Output
The subwoofer output should connect to a 2-ch/Mono amplifier that controls your subwoofer.
Using Application
- Smart EQ App
All of Smart EQ’s settings and configurations can be accessed and controlled by Smart EQ app (available on iTunes App Store and Google Play Store) on a Bluetooth enabled iOS/Android device.
Bluetooth Pairing
Connect Smart EQ to Bluetooth enabled iOS/Android device in order to control Smart EQ.
-
Pairing the Smart EQ with Your Device
Pairing is the process of connecting two devices over Bluetooth and allowing them to communicate. You will need to go through the pairing process with each device you use with Smart EQ.
Note: If your device requires a passcode to connect during the pairing process, use ‘1234’.
Please note that Smart EQ can only be actively connected to ONE device at a time. To connect Smart EQ to a new device, the first device’s Bluetooth function must be turned off or be out of range of the Bluetooth signal. The Smart EQ will always remember the last connected device. When Smart EQ is turned on, it will first attempt to reconnect to the last connected device before attempting to connect to a new device. -
Pairing Smart EQ with iOS Devices
Note: These instructions were written using iOS 8.1 and may differ depending on the version of iOS on the device.
1. Go to Settings → Bluetooth
2. Turn Bluetooth on. The iOS device will automatically begin looking for Smart EQ.
3. Start the vehicle or set the key in ACC position. Smart EQ’s Power LED will turn on (red).
4. On the ‘Other Devices’ section of iOS Bluetooth settings, Smart EQ will appear as ‘SmartEQ-xxxxxx’ (the last 6 digits are Bluetooth ID and will vary from device to device).
5. Tap on ‘SmartEQ-xxxxxx’ from the list of ‘Other Devices’ to connect. If passcode is required, enter ‘1234’.
6. Once connected, ‘SmartEQ-xxxxxx’ will move to the list of ‘My Devices’ and will show status as ‘Connected’.- Pairing Smart EQ with Android Devices
Note: These instructions were written using Samsung Galaxy Note 3 and Android 4.4.2 and may vary depending on the device and Android version.
1. Enter the device’s Bluetooth setting (Menu → Settings → Connections tab → Bluetooth) and make sure that Bluetooth is turned on.
2. If ‘SmartEQ-xxxxxx’ doesn’t show up on ‘Available devices’, press ‘Scan’ on the bottom of the screen and Smart EQ will appear on the list as ‘SmartEQ-xxxxxx’.
3. Tap ‘SmartEQ-xxxxxx’ to connect. Enter passcode (1234) if necessary.
4. ‘SmartEQ-xxxxxx’ will now be seen on the ‘Paired devices’.Troubleshooting
