The Signal Transfer Phono Preamplifier.

Unbalanced output version.

RIAA phono preamp; unbalanced output
The Signal Transfer Stereo Phono Preamplifier is a stand-alone version of the phono sysytem used in the Precision Preamplifier. It offers both moving-magnet and moving-coil inputs, the latter with two gain options for optimal performance. It gives extremely accurate RIAA equalisation, a noise performance that approaches the theoretical limits, and superb linearity.

RIAA EQUALISATION ACCURACY

This graph shows the typical RIAA equalisation accuracy. The error is less than 0.1 dB from 100 Hz to 40 kHz.

The response is affected by the subsonic filter below 100 Hz, but is still accurate to -0.5 dB at 50 Hz.

Note that the Y-scale is enormously expanded.

Measurement system: Audio Precision SYS-2702.
