The Midland BTX2 PRO S LR is the industry's first mid-range intercom that can communicate with up to eight additional people. All of this is done in full duplex mode, with digital quality, a DSP noise reduction system, and an AGC system (which can be turned off) that adjusts the volume automatically in response to background noise. The BTX2 PRO S LR has a range of up to 1.6 km*. Midland intercoms contain two channels, one of which is labeled 'Talk to All,' allowing them to be used with devices from other manufacturers. Share music, listen to FM radio with RDS and 6 preset stations, use vox and voice commands, connect to two mobile phones at once, set up on a PC or mobile, and customize settings using the BT Set App.
