Electronic Crossovers (frequency dividing networks),
Solid State and Tube, MOSFET Power Amplifiers, Passive Preamps.
Welcome to Marchand Electronics Inc. We manufacture high quality
audio 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 networks download
the users guide from 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 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 crosovers 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.
