Custom Electronic Design
Welcome to Marchand Electronics Inc. We make high quality electronic equipment. Our products include electronic crossover networks, both solid state and vacuum tube, and modular audio amplifiers. These pages contain information on all our products, pricing information and ordering information.
We specialize in Electronic
Crossover Networks and Power Amplifiers. Electronic Crossover
Networks are used to improve the sound of a sound system by
separating the high frequency sounds from the low frequency
sounds and using a separate power amplifier and speaker for
each. This is often called Bi-Amping. Typical crossover points
range from about 500 to 3000 Hz. The Crossover Networks are also
ideal for driving a Powered Subwoofer. Typical crossover
points for subwoofers range from 40 to 150 Hz. For
detailed information on how to use our electronic crossover

Articles, Computer Programs and Manuals. Electronic crossovers are
sometimes called active crossovers. Both refer to the same
thing: line level crossovers that are used between preamp and
We use high quality parts only. Most resistors are 1% Metal Film, and the filters use Polypropylene capacitors. All connectors are gold plated. All crosovers have a standard 100/115/230VAC 50/60Hz power supply with detachable line cord (IEC connector).
