· Please read this User Guide before installation and use.
· CAUTION: The power input voltage range for your Bluetooth®
Receiver Remote Control (referred to as Receiver) is 9V to 16V.
It is designed to work with a +12V DC battery power supply. If
your vehicle battery power output is not 12V (e.g., 24V, 36V, or
48V), you will need a voltage converter with 12V output (e.g.,
a 48V-to-12V converter). Connecting the Receiver directly to
higher voltages will cause damage to your device and VOID
THE PRODUCT WARRANTY.
· The Receiver has a Remote Turn-On Input feature; this is an
optional connection to your vehicle ignition switch so you can turn
the Receiver on or o via the ignition switch. When this input has a
signal between 12V to 56V, the Receiver will turn on. When there is
no input voltage, the Receiver will turn o.
· The Receiver’s audio outputs are pre-amplified signals that need
to be connected to a power amplifier, radio, or powered speakers
(sold separately).
· The Receiver fits in a standard Carling rocker switch opening,
which is commonly used in the dashboard of many o-road
vehicles, boats, and golf cars. The Receiver panel is waterproof;
however, the housing behind the panel is only splash proof.
· CAUTION: In order to make sure there is no potential damage to
your audio system, unplug or power o your audio equipment until
after all connections are completed.

Introduction
Features
The Receiver is an all-in-one device that supports Bluetooth,
EcoCast, and Aux-In.
Bluetooth
The Receiver utilizes Bluetooth 5.1, which provides up to 100 foot
Bluetooth range and dual simultaneous smartphone connections.
EcoCast
The Receiver also has EcoCast built-in, which allows the Receiver
to broadcast (transmit) or receive audio streams to/from other
EcoCast-enabled products. ECOXGEAR and SoundExtreme

work with the Receiver, you can skip all EcoCast-related content.
All EcoCast-enabled products have two optional streaming modes:
· EcoCast Transmitting Mode. When set in this mode, the EcoCast-
enabled product transmits either Aux-In or Bluetooth Audio to
multiple wirelessly connected EcoCast-enabled products.
· EcoCast Receiving Mode. When set in this mode, this Receiver
product receives audio from another EcoCast transmitting audio
product, like a SoundExtreme soundbar, radio, or tower speaker.
Receiver Audio Modes
The Receiver has the following 4 Audio Modes: Speaker (Bluetooth)
Mode, EcoCast Transmitting Mode, EcoCast Receiving Mode, and

Installation and Wiring
Installing Your Receiver Onto Your Vehicle
The Receiver is designed to snap into a standard Carling style
rocker switch opening.
· If you already have that style of an opening on your vehicle, you can
simply snap the Receiver into place.
· If your vehicle doesn’t already have that style of an opening, you
will need to cut a rectangular hole into your vehicle. Before you cut,
please refer to the dimensions under the Specifications section to
determine the cutout size.
Connecting to 12VDC Power Supply
The Receiver does not have an internal battery. It must be connected
to an external 12VDC power supply to function. When you install
the Receiver to a battery or a voltage regulator on a golf cart, a boat,
a quad bike, a UTV, or another vehicle, you need to make sure that
your vehicle battery or battery pack terminal voltage is 12VDC. If the
battery terminal voltage is not 12V, you will need a DC–DC converter
with output 12V. Connecting the Receiver to a non-12VDC power
source will lead to a malfunction or damage to the Receiver.
Recommendation: If you are not familiar with all of the vehicle’s
battery or ignition switch connections, consult your vehicle’s manual
or a technician. Incorrect connections
to your vehicle’s battery or ignition
signal terminal may cause damage to
your speaker and your vehicle.
Connect the +12V and GND wires
to the 12VDC power supply.
· Make sure that the RED Wire
is connected to +12V battery’s
positive (+) terminal and the
BLACK Wire is connected to
battery’s negative (-) terminal. Black Wire Red Wire

Connecting the Remote Turn-On Input Wire to a Switch
Besides the 12V power supply, the Receiver has an optional Remote
Turn-On Signal Input to turn on and power o via your vehicle's
ignition switch. The input voltage range to turn on is 12V to 56V.
When the input voltage is 0, it will power o the receiver.
You will need to connect the (Dark Blue) Remote Turn-On Wire to the
vehicle ignition switch with an extension cable (not included). If you
are not able to connect it to your vehicle's ignition switch, connect
this input to a rocker switch (not included), then connect the rocker
switch to a 12V to 56V power supply on your vehicle or to a switch
accessory panel.
Connecting to a Switch
To connect the Receiver to your vehicle’s ignition switch, a rocker
switch, or the vehicles switched power distribution panel, follow the
steps below:
1. Connect the (Dark Blue) Remote Turn-On Wire to the
Accessories terminal of your switch with an extension cable.
2. Once the connections are completed, the Receiver will turn on or
