The CT2 Balanced Audio Volume Controls are high quality 4 channel 24 position stepped attenuators. They were designed for maximum sonic quality, accuracy and reliability. Their series resistor networks consist of 23 non-inductive, low noise, SMD metal film resistors for short signal path and very low inductance and stray capacitance. These 24K Gold plated high precision rotary switch have very accurate attenuation and tracking of 0.05dB. Components are manufactured in Switzerland.
