Miracle Electronics Audio Attenuators / Volume controllers are designed with one goal in mind. Crystal clear sound, which is clearer than reality. Our Volume controllers are designed for maximum sonic quality, accuracy and reliability. They are specifically designed and are highly suited for audiophile applications and for professional applications. Miracle Electronics Volume Control switch comes with 11 volume steps (10 regulator steps and 1-zero position) and besides this, they possess an E/M relay (24VDC), which makes emergency announcements possible even if control is at position “0”. The Switch is based on a compact design, which provides for shorter signal path than conventional attenuators. The design also effectively reduces inductance and stray capacitance to achieve increased sonic quality over an increased bandwidth. And of course, all of this while ensuring reduced distortion. Miracle Electronics Volume Control Switch: Enabling crystal clear sound Our Volume control switches / Audio Attenuators are extremely durable, come with superior wiring, varnishing, connection terminators, generate less acoustic noise, have a low EMR with a low profile.
