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.

xm44insideWe 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 networks download the users guide from ArticlesComputer 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 power amp.


We use high quality parts only. Most resistors are 1% Metal Film, and the filters use Polypropylene capacitors. All connectors are gold plated. All crossovers have a standard 100/115/230VAC 50/60Hz power supply with detachable line cord (IEC connector).

All our products have a warranty of two years from the date of purchase. If they fail for any reason, just return the unit to us and we will fix it for free. We also have a customer satisfaction policy. If you are not happy with your purchase, just return it to us within 30 days of purchase, and we will send you a full refund. We accept Paypal, MasterCard, VISA, Discover, American Express and Checks. (how to order).

We also sell the boards only. This is useful for embedded solutions, where a crossover is installed into some other equipment, like an amplifier. See XM1, XM9, XM16 or XM44.
