What is a ”High Quality Sound Resistor“?
• The quality sound resistor creates high fidelity sounds with high resolution and clearity when used in Signal Processing Circuits (D/A Converter, Amplifier, … etc.)
for sound related equipment such as Audio and Voice signals.
• It is the same shape and compatible with RK73 Series.
Comparison with general purpose chip resistors:
• Production Method: Strictly selected materials are used for high quality sound and the production is controlled at specialized processes.
• Performance: The general characteristics are the same as standard resistors, which makes it possible to be used for existing models.
• Sound Quality: Heavy bass echo, high frequency sound, resolution, clearity, etc. are improved.
