Audio Gold Resistors from Ohmite
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 simpli-
fied 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.
FEATURES
• 3 watt to 50 watts
• Non-magnetic materials
• Mono-metallic design
• Welded connections
• Non-inductive versions available
• Reduces signal distortion
• Minimizes thermal EMF
• Reduces current noise
• Superior mid-range frequency performance
• Improved stability
