NM250A biamped, 2-way active system with 2 power amps, 2 processors and electronic cross-over Balanced INPUT, with adjustable sensitivity (microphone -40dB / 2kohms or line 0dB/20kohms), fitted with a Neutrik Combo connector which accepts both 3 pin XLR and stereo jack plugs. Input sensitivity switch (mic when pushed in). Balanced OUTPUT(in parallel with the input), using a 3 pin XLR connector. It allows for easy parallel connection of NM250A or active systems. Master volume control (adjusts the input levels of the 2 built-in power amplifiers to adapt them to the output level of the mixer. It also allows to adjust the volume of the system when it is used in parallel with others). Peak led indicator 2-band equalizer. It allows changing the response curve of the system depending on the requirements of each different application. This enables optimizing the NM250A's working condition for each specific requirement whether it is used for example in a conference hall, on stage for monitoring and many other situations.
