DESCRIPTION
Unlike the output from a CD player the raw signal from a phono cartridge suffers frequency distortion
because the output at 20 Hz is 1000 times lower than that at 20 kHz. This is deliberately implemented during
the recording process to enable the signal to be cut into the vinyl of the record. The phono preamplifier must
restore the frequencies to their correct balance using an RIAA equalization curve. The Sensor 2 uses passive
equalization in two stages to achieve this.
