PARTS EXPRESS BX-4 Bluetooth Audio Receiver Instruction Manual

GENERAL INTRODUCTION

BX-4 is a Bluetooth® receiver with 5.0 chip. This chip offers high quality sound and makes the compatibility and integral performance more optimizing. Just use 3-pin XLR to connect console or active speaker, then using Bluetooth® to connect smart phone, pad such devices to realize wireless transmission. STEREO-LINK button helps BX-4 pairing with another BX-4 to transmit the signal to audio equipments.

CONNECTION INTRODUCTION

1. USB CHARGE: charging interface supply power to devices.
2. POWER ON/OFF: push switch-turns the BX-4 on and off.
3. PAD 0dB -10dB: sensitivity attenuator, lower the input signal sensitivity and avoid signal overload and distortion.
4. CHARGE: battery indicator,during charging the blue light lits, when battery is already full, the indicator goes out.
5. LED indicator: when turn on the BX-4, the product to be paired, red and blue light lit alternation; when paired successfully, blue light flash slowly. When paired and Bluetooth played music, blue light solidly lit; if no music, blue light flash slowly.
6. STEREO-LINK button: press the button(STEREO-LINK) on both BX-4 for 2 seconds, the blue light flash quickly(on both BX-4 LED indicator flash). Each BX-4 searched for each other, when they are successfully paired, one BX-4 red and blue light lit alternation another BX-4 blue light flash slowly(at that time, the output signal is STEREO).
7. XLR: balanced output connector

SETUP

1. Insert bx-4 to mixer’s XLR input connector.
2. Use 1/4″(6.35mm) cable to connect 1/4″(6.35mm) input connector on active loudspeaker and 1/4″(6.35mm) output connector on mixer.
3. Paired with Bluetooth devices. NOTE: you can connect to mixer, amplifier or other devices that accepts line-level inputs(this device must be powered off). Here take the mixer as an example.

BLUETOOTH PAIRING A SINGLE BX-4

1. Power on your Bluetooth device.

2. Power on BX-4 red and blue light flash alternation.
   

3. Red and blue light flash alternation, to be paired.

4. Navigate to your bluetooth device set up screen, find Alctron BX-4 and connect.
   

5. When paired successfully, blue light flash slowly. When paired and Bluetooth played music blue light solidly lit: if no music , blue light flash slowly.
   

6. Adjust the volume on your Bluetooth device.

STEREO-LINK 2BX-4

1. Press the STEREO-LINK button on both BX-4 for 2 seconds.
   

2. Both STEREO-LINK LED will flash blue light quickly. Then BX-4 will search for each other.
   

3. When they are successfully, one BX-4 red and blue light lit alternation another BX-4 blue light flash slowly
   

4. Following BLUETOOTH PAIRING A SINGLE BX-4 steps to connect with Bluetooth devices.
