Sensor 2

About the Sensor 2

The RCM Audio Sensor 2 is a phono preamplifier designed to deliver exceptional sound quality with a high output level of 2 volts, matching the output of an average CD player. It supports both MM and MC cartridges with an amplification range up to 76 dB, achieved through a carefully designed balanced circuit and selectable input impedance and gain via DIP switches. The device features a two-step passive RIAA correction system using hand-selected low-noise resistors and polypropylene capacitors, ensuring signal fluctuations below 0.3 dB from 20 Hz to 20 kHz. The power supply is external, housed separately to minimize noise and distortion, with a symmetrical design and high-quality components. Outputs include both balanced XLR and unbalanced RCA, with selectable output stage mode. The chassis is made from non-magnetic materials with a hollow rectangular cross-section tube design to reduce flexing and resonance. The Sensor 2 offers a wide soundstage, deep bass, and musical tonal balance, making it highly regarded among audiophiles for its transparency and musicality. It is considered excellent value for its price point and has received positive reviews for build quality and sonic performance.
