Frequently Asked Questions - BT-DI ART

How do I pair my Bluetooth device with the ART BT-DI?

Press and hold the pairing button for 4 seconds. The LED will flash quickly. On your streaming device, select "BT-DI_vx" from the Bluetooth menu. Once connected, the LED becomes steady blue.

Can the BT-DI be powered by phantom power?

Yes, the BT-DI can be powered by a pair of +48V phantom power lines via the XLR outputs. However, both XLRs must be connected to phantom sources to power the unit fully.

What is the function of the Ground Lift switch?

The Ground Lift switch lifts the ground connection when the unit is powered over USB. This helps eliminate ground loop noise that may come from a computer.

How do I use the headphone output?

The headphone output is a 1/4" TRS jack. It can monitor the input signal. Use the Mono/Stereo switch to choose between summed mono or stereo output.

What is the difference between Main and Monitor outputs?

The Main outputs are balanced XLR jacks with transformer isolation. The Monitor output is a 1/4" TRS for headphones or line-level input. The Main/Monitor switch bypasses the level control on the Main output when set to down position.

What Bluetooth codecs does the BT-DI support?

The BT-DI supports SBC and AAC codecs.

What is the maximum Bluetooth range?

The rated line-of-sight range is 30 meters (100 feet). Range can be affected by obstacles and 2.4 GHz interference.

How do I reset or unpair a connected Bluetooth device?

Press and hold the pairing button for 4 seconds. The blue LED will turn off for 1 second, then blink rapidly, indicating the device is ready for pairing with a new device.

Is the USB port for audio streaming?

No, the USB port is only for power (5V DC). It does not pass audio data.

What is the warranty period?

The ART BT-DI comes with a 3-year limited warranty from the date of purchase to the original owner, covering defects in materials and workmanship.

INTRODUCTION

Thank you for purchasing Applied Research and Technology's BT-DI. The ART BT-DI is a rugged and flexible Bluetooth Audio DAC. It is designed to provide a reliable Bluetooth interface to products like mixers and line level amplifiers. The thick steel case offers maximum protection for years of use.

FEATURES

• Bluetooth 5.0 receiver
  • External antenna for long-range operation
• Transformer isolated XLR outputs
• Headphone out
• Selectable fixed/variable Main output
• Powered by 5V external USB supply OR Phantom Power
  • Headphone out can be summed Mono

CONNECTIONS

Power

The BT-DI can be powered from a USB source or the unit can be powered from two phantom power sources. This unit will require two phantom sources to power the unit fully.

1. Bluetooth Antenna: This antenna extends the audio Bluetooth operational distance.
2. Bluetooth pairing switch and indicator LED: This is the Pairing switch for initializing the pairing or unpairing

function. The indicator LED shows the pairing status of the BT-DI.

1. Level control: This pot varies the output level.
2. Main/Monitor Switch: In the down position, the Level control is bypassed on the Main output.
3. Monitor Out: The TRS 14 " jack, allows monitoring of the input signal. Connect this jack to a pair of headphones out or to a line level input.
4. Mono/Stereo Switch: Toggles the signal on the Monitor Out between Stereo and Mono.
5. Main Outputs: Left and Right XLR Balanced Output jacks. The BT-DI can also be powered by a pair of +48V phantom power lines through the XLR jacks, typically supplied on microphone input channels on a mixer.
6. Ground Lift Switch: This switch lifts the ground when the unit is powered over USB to avoid any ground noise coming from a computer.
7. USB Jack: The BT-DI can be powered from a USB 5V DC USB A to USB B source. The BT-DI can also be powered via phantom power applied to both XLR outputs. The USB port does not pass any audio data between the BT-DI and a computer.

INSTALLATION and OPERATION

BLUETOOTH

Bluetooth™ Section

The BTDI is capable of receiving streaming audio over Bluetooth ^™ from devices such as smartphones and laptops. Pairing your device with the BTDI is simple and gives you the freedom to play your music wirelessly.

1. Pairing / Bluetooth™ Pair Button. When the Pair Button is pressed for 4sec, the Bluetooth™ audio connection is available for pairing. After pressing the Pair Button, go to the Bluetooth™ menu on your streaming audio device. You will see a device named "BT-DI_vx". Select this device to initiate pairing. Once you see the "BT-DI_vx" device connected, you will be able to stream audio to the BT-DI.

2. Disconnecting the paired device requires the pairing button to be pressed for 4sec. The blue LED will turn off for 1sec, then blink fast waiting to be paired to another device.

3. Bluetooth™ Status Indicator. The blue status indicator alerts the user to the current status of the Bluetooth™ connection. A fast-blinking light indicates an available, unpaired connection. Constant steady Blue light means there is an active connection. A slow blinking

light means that the Bluetooth ^TM connection has been lost.

1. Bluetooth™ Level Control. Use this control to set the audio level for the Bluetooth™ connection. Level can also be controlled directly at your streaming device.

The BTDI Bluetooth ^™ operating range is rated for 30 meters (100 feet) line of sight. The quality of the link can be affected by an excess of traffic in the 2.4GHz band or structures between the streaming device and the BT-DI unit.

APPLICATIONS

The BT-DI Works well with computers, Bluetooth capable tablets and various mobile devices (cell phones). This extends your signal distance without the use of cabling and offers a balanced low impedance audio path for your audio source.
