PRO BT5

OVERVIEWS

PRO BT5 is a passive DI box specially designed for playing back music from wireless mobile devices and built-in Bluetooth Ver.5.0 A2DP DUAL MODE module. The balanced output level will not be affected by the potentiometer. The output side is equipped with a TYPE-C USB terminal which requires a 5VDC power adaptor, power bank or USB port from computer to power the BT5 such as the power supply method of the general mobile device. BT-5 is excluding the TYPE-C cable and power adaptor.

The built-in Bluetooth module has BR/EDR dual-mode control function, A2DP stereo playback mode and BLE energy-saving mode. And using Qualcomm chips and DA/DSP, audio converting and sampling rate are 16bit and 44.1KHz.

The PRO BT5 has a pair of built-in UNiKA-PROTM EI30A10E 1+1:1+1 isolation transformers. The transformer has a special copper foil layer and a dedicated grounding layer, which can restore the high signal/noise ratio and dynamic sound of the device, and avoid unnecessary Leakage caused by radio frequency interference, grounding interference and potential difference.

PRO BT5 is especially suitable for mobile phones, computers and any of Bluetooth music players. It converts wireless signals into low-impedance balanced signals, which is convenient for extending the wiring distance and blocking interference.

PRO BT5 has built-in mini TRS headphone monitor output and monitor volume control, which can drive 16Ω~300Ω headphones to be allowing users to monitor the content that needs to be played in advance.

Note: Since the device does not include charging identification IC, some of power bank with QC function may not be available or may stop supplying power halfway because the IC is not detected.

On the other hand, the power bank with automatic stand by mode is not recommended.

DESCRIPTION

Search and connect your PRO BT5

When you use your computer, mobile phone, multimedia device to search and connect to PRO BT5 via Bluetooth 5.0 or higher version, please connect the power of PRO BT5 first, then the power light on the upper cover will light up, and the SYNC indicator on the front side will flash. Please find the following names on your mo bile device search list,

UNiKA PRO-BT5-XXXX

Where “XXXX” is the last four digits of the device’s MAC* address which is factory preset. For example, if the MAC address of the device is (DC:00:30:00:1E:1A), you will see UNiKA PRO-BT5-1E1A in the list of connectable devices. If there are multiple PRO BT5 nearby simultaneously power on, you will see the last four digits of a different MAC, such as PRO-BT-5-1E13, but it may have been connected by other mobile devices, so if your mobile device is connected to this device, it will show that it cannot be connected, otherwise it will It displays words such as successful connection or successful connection as an audio playback device.

  

*About MAC address

A media access control address (MAC address) is a unique identifier assigned to a network interface controller (NIC) for use as a network address in communications within a network segment. This use is common in most IEEE 802 networking technologies, including Ethernet, Wi-Fi, and Bluetooth. Within the Open Systems Interconnection (OSI) network model, MAC addresses are used in the medium access control protocol sublayer of the data link layer. As typically represented, MAC addresses are recognizable as six groups of two hexadecimal digits, separated by hyphens, colons, or without a separator.
