Bluetooth reception up to 12 meters(40 feet!)
Double balanced XLR output connected to PA system
Built-in headphone amplifier for troubleshooting
Isolate the transformer to eliminate hum and hum
BT-Pro is a Bluetooth direct box, designed to capture data from Bluetooth® The wireless transmission of the equipment, and the signal is converted into a balanced line for use in the PA or recording system. It uses an innovative T-shaped access cavity, and the antenna is located behind it. This passed by Sintra®(A strong closed-cell PVC)The made milling blade is protected, allowing wireless transmission signals to pass without interference, allowing the line of sight distance between devices to be 12 meters(40&39;)Or bigger.
The audio signal path itself uses 2.0 EDR(Enhanced data rate)The new Bluetooth wireless A2DP interface is used for higher-speed transmission to provide high-quality audio quality. The standard uses a 16-bit wireless compression format with an actual bit rate determined by the transmission source material. Internally, BT-Pro converts the data into a stereo analog signal, generating up to +4dB at the output. The signal level is controlled by the front panel potentiometer, which is shared with the built-in headphone amplifier, with a standard 3.5mm mini TRS for troubleshooting. For greater flexibility, the stereo-to-mono switch adds the stereo outputs for two-channel operation to reduce input channel requirements on the mixer or to share signals between different systems. If noise is encountered, two side-mounted isolation transformers can be inserted into the signal path. In addition, there is a ground lift switch for XLR to further help eliminate hum and hum caused by ground loops.
It is easy to connect to BT-Pro. BT-Pro is powered by an external 5V power supply through the mini USB port, or it can be powered by a laptop or USB hub. Once turned on, the two top mounted LEDs will switch while waiting for pairing. Turn on the Bluetooth device, and its transceiver sends an initial pairing message to identify BT-Pro. This will show up as&39;RadialEng&39;. Then use the connection passcode to initialize the connection. This important security feature ensures that other nearby Bluetooth devices will not“ Pollution or hijacking” System. Once paired, the blue LED of BT-Pro will flash every 3 seconds to let you know that the two Bluetooth devices are talking to each other.
Simple control set
Radial BT-Pro is easy to operate, even when multitasking before the show. The LED on the front panel indicates whether the device is paired and transmitted. There is a ground lift switch to eliminate ground loops and single-stage knobs due to(Control balanced output and headphone output)Noise.
High-quality Bluetooth audio and security
The advanced Bluetooth receiver in Radial BT-Pro can ensure you get the best audio playback effect through Bluetooth, and the transformer isolation output can provide sufficient signal level with ultra-low noise. And you don''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''t have to worry about someone hijacking the audio stream with your own Bluetooth device-once the device is paired with BT-Pro, a password is required before the audio can be streamed.
