Product Description

The RCM Sensor 2 phono preamplifier provides precise RIAA equalization for cartridges in the range of 0.3 mV to 5 mV, and outputs a line level signal of 2 Volts at 1 kHz.

Easily accessible switches on the back panel allow the user to adjust cartridge load impedance, gain and mode of input stage (balanced or single–ended).

RIAA equalization is achieved via a passive split network with two separate RC filters, low noise resistors and 1% tolerance polypropylene capacitors.

To ensure high precision in the RIAA equalizer each component of the filter is hand picked and measured to guarantee a tolerance of less then 0.3 dB in the frequency range 20Hz – 20 kHz. This is done for every unit built so that the customer receives a unit sounding as good as the reference unit in our laboratory.

All other components in the preamplifier are selected to ensure perfect channel balance.

Because of the extremely high gain capability of up to 76dB combined with a very low noise floor the Sensor 2 can amplify very low output MC cartridges with ease. Music emerges from a black background and images are finely crafted and spread out before you in a sound stage that is both wide and deep. Detail retrieval is exceptional and the ability to communicate Pace, Rhythm and Timing (PRAT) is very satisfying.

Sensor 2 performs at such a high level that it can be used in the most expensive audiophile systems, however its very reasonable price allows music lovers at all levels to enjoy the superb sound it produces.
