Optical Equalizer
Optical equalization powers an optical phono cartridge’s light source and applies the frequency correction it needs. The resulting analogue line-level signal feeds a preamplifier or amplifier’s line input.
The cartridge uses light to detect stylus movement. This is analogue record playback; a digital optical input does a different job. An ordinary moving-magnet (MM) or moving-coil (MC) phono input cannot substitute for the optical cartridge’s power supply and equalization.
This function can sit in a dedicated optical equalizer or alongside MM/MC circuits in a phono stage with a separate optical-cartridge input. Check the supported cartridges and required signal and power connections; the word “optical” alone does not establish compatibility.
Output voltage, output impedance and minimum output load impedance help you match the following line input. On hybrid stages, use the specifications for the optical input. A low-cut filter, where provided, reduces very low-frequency disturbance from sources such as warped records.
