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.
3. Level control: This pot varies the output level.
4. Main/Monitor Switch: In the down position, the Level control is bypassed on the Main output.
5. Monitor Out: The TRS ¼” jack, allows monitoring of the input signal. Connect this jack to a pair of headphones out or to a line level input.
6. Mono/Stereo Switch: Toggles the signal on the Monitor Out between Stereo and Mono.
7. 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.
8. Ground Lift Switch: This switch lifts the ground when the unit is powered over USB to avoid any ground noise coming from a computer.
9. 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™ connection has been lost.
4. 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.
