Mitchell

Analog electronic crossover

The ultimate solution for authentically analog multiamplified systems

The Mitchell Analog Electronic Crossover is an incredibly versatile frequency division device that can be easily configured to fit virtually any speaker system for multi-amplification.

Most speakers use a passive network (called a “crossover”) to divide the sound spectrum so that each speaker receives the appropriate frequencies: low frequencies to the woofer, medium frequencies to the midrange, and high frequencies to the tweeter.

The passive crossover is subject to various compromises that limit the performance of the loudspeaker. The only solution to eliminate the effect of these compromises on the sound of the speaker is to use an active crossover instead, along with an amplifier for each speaker. This method is called “active multiamplification.”

The Mitchell has six programmable filter modules to achieve a 3-way stereo crossover filter or a 6-way mono filter. Modules in each channel can be cascaded to achieve more complex filter networks at the cost of reducing the number of ways.

Each module can be programmed to be a low-pass filter, a high-pass filter, or a band-pass filter. Additional notch filters and a shelving function (band enhanced or band attenuated) are provided, along with an all-pass filter to perform phase alignment. Each module can be programmed independently, and the output level and phase of each module can be set independently.

The Mitchell is configured through a USB connection via an application running on Windows computers (Linux and Mac versions available later) that allows total freedom in setting the various configurations of each module, as well as giving support for designing filters of various types: Butterworth, Chebishev, Bessel.

The Mitchell has both single-ended and balanced inputs and outputs. A trigger input allows on/off control from another device (such as a preamplifier). The Mitchell is also equipped with an IR receiver to detect the on/off command from the standard M2Tech teelcom. The operation of this received IR receiver is also programmed via the app.

M2Tech Mitchell: il componente che non esisteva (prima parte)

Il Mitchell è un crossover elettronico integralmente analogico, privo di comandi diversi dall’accensione dato che è controllato tramite PC da un apposito software di gestione. Oltre ai basilari filtri passa-basso (da qui in poi indicati come PB) e passa-alto (PA) ha funzioni di “shelving” (termine traducibile con “modellamento”, dato che “scaffalatura” ha poco senso) della risposta e capacità di alterare la sola fase del segnale tramite un filtro passa-tutto (PT) del primo ordine....
