Optical Equalizer
An optical equalizer is a phono stage for an optical cartridge. It powers the cartridge’s light source and corrects its frequency response, producing an analogue signal for your amplifier.
Where it fits
Connect its output to a line input on a preamplifier or integrated amplifier. An ordinary moving-magnet (MM) or moving-coil (MC) phono input cannot replace the optical stage: it lacks the required power supply and uses different frequency correction.
Dedicated or combined
This catalogue groups dedicated optical stages under Optical Equalizer. A phono stage that also accepts MM or MC cartridges belongs under Phono Preamp, even when it includes optical-cartridge support.
What to check
Confirm the supported cartridges and the required tonearm wiring and power connections. Choose an amplifier line input whose impedance—the electrical load seen by the equalizer—is at least the specified minimum. Check its connectors and signal-level limits too. Some units offer a low-cut filter to reduce very low-frequency disturbances from warped records. Filter settings and connection requirements vary, so use the instructions for the particular unit.
