INSTALLATION / OWNER'S MANUAL
Preparation
TYPICAL MOUNTING METHOD
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.

INSTALLATION / OWNER'S MANUAL
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.

(RCA)
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: Do not connect both low and high level inputs at the same time.

TO GROUND
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).
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.

INSTALLATION / OWNER'S MANUAL
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.

INSTALLATION / OWNER'S MANUAL
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.
When the unit is paired and connected,
it will show the name of the Smart EQ.
Select the input source by selecting either the Head Unit
or Bluetooth Streaming button.
To control the 7-band EQ, slide the EQ frequency bars up
and down.
To select a pre-defined EQ setting including the saved
settings, press the right side of pre-defined EQ or scroll
using the left/right arrow.
To make a personal EQ setting, slide and adjust the EQ
bars, then the custom EQ setting will be displayed as
'Temporary'. Press the 'Save' button to save the
customized EQ setting. To make a personal EQ setting,
slide and adjust the EQ bars, and the EQ setting will be
displayed as 'Temporary'. Press the 'Save' button to

INSTALLATION / OWNER'S MANUAL
Using Application
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'.
