Latest addition to the RCM Audio product range is the RCM SENSOR PRELUDE IC phono
preamplifier.
Built to the highest quality standards this preamplifier provides precise RIAA correction 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 correction 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 correction 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.
The SENSOR power supply is housed in a separate metal case to eliminate
interference with the sensitive circuits in the phono preamplifier. It is
fully balanced and has oversize filtering capacity and low output impedance.
Because of the extremely high gain capability of up to 76dB combined with a very low
noise floor the Sensor Prelude IC 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 Prelude IC performs at such a high level that it can be used in the most
expensive audiophile systems, however its very reasonable pricing allows
music lovers at all levels to enjoy the superb sound it makes.
