Audio Gold Resistors
audio applications
Ohmite now offers the Audio Gold Resistor Family, specifically
designed for high-end loudspeaker and amplifier applications.
These resistors utilize high quality resistance wire wound on
a ceramic core, terminated, and finished with our flameproof
Centohm® coating.
Ohmite’s Audio Gold resistors have been carefully engineered
with non-magnetic materials to eliminate the effects of these
stray magnetic fields on circuit performance, thereby resulting in
simplified shielding requirements and improved sound quality.
Audio Gold resistors are designed for use in cross-over net-
works and as source, emitter, or cathode resistors in balancing
applications for output transducers.
