Quad QC-24P Phono Stage A Tribute to Analog Purity The Quad QC-24P Phono Stage embodies Quad's commitment to high-fidelity analogue sound. Designed by renowned valve expert Tim de Paravicini, this dedicated valve phono preamplifier caters to both Moving Magnet (MM) and Moving Coil (MC) cartridges, ensuring versatility and exceptional audio performance. Precision Engineering At the heart of the QC-24P lies a valve complement of four 6111 triodes, chosen for their low noise and high linearity characteristics. This configuration contributes to the unit's impressive Total Harmonic Distortion (THD) of less than 0.08% (A-weighted), delivering clear and detailed sound reproduction. Versatile Gain Settings The QC-24P offers three selectable gain settings—High, Medium, and Low—to accommodate various cartridge outputs. This flexibility ensures optimal performance across a wide range of vinyl setups, from high-output MM cartridges to low-output MC cartridges. Dual Output Options Equipped with both fixed and variable line-level outputs, the QC-24P provides flexibility in system integration. The variable output allows for direct connection to a power amplifier, bypassing the need for a separate preamplifier, while the fixed output is ideal for integration with existing preamplifiers.
