M2Tech Mitchell Analog Electronic Crossover

Mitchell Analog Electronic Crossover

The ultimate solution for true-analog multi-amplified systems

The Mitchell Analog Electronic Crossover is an incredibly versatile frequency dividing device which can be easily configured to fit virtually any speaker’s system for multiamplification.

Most loudspeakers use a passive network (called “crossover”) to divide the sound spectrum so that each driver received the appropriate frequencies: low frequencies to the woofer, mid frequencies to the midrange and high frequencies to the tweeter.

The passive crossover is subject to various tradeoffs that limit the loudspeaker performance. The only solution to overcome the tradeoffs effect on the loudspeaker’s sound is to use an active crossover instead, together with an amplifier for each driver. This method is called “active multiamplification”.

The Mitchell is provided with six programmable filtering modules to achieve a 3-way stereo crossover network or a 6-way mono network. Modules in each channel can be cascaded to obtain more complex filtering networks at the cost of reduced number of ways.

Each module can be programmed to be a low-pass filter, a high-pass filter or a band-pass filters. Additional notch filters and a shelving (enhance-band or attenuate-band) feature are provided, together with an all-pass filter to perform phase alignment. Each module can be programmed independently and each output level and phase can be set independently as well.

The Mitchell is configured thanks to an USB connection by means of an app running on Windows computers (Linux and Mac versions available later) which allows for total freedom in setting the various configurations of each module, as well as gives support for filter design of various kinds: Butterworth, Chebishev, Bessel.

The Mitchell is provided with both single-ended and balanced inputs and outputs. A trigger input allows for power on and off by another device. The Mitchell is also provided with an IR receiver to sense the on/off command from other M2Tech devices. The operation of this IR received is also programmed by the app.
