Item Description.
This listing is for a MM/MC compatible phono equalizer amplifier Ver. 4.
(Features)
Thin-film polymer multilayer capacitors (PMLCAP) are used in the output coupling capacitor.
High sound quality by using polyphenylene sulfide film capacitors in the equalizer circuit
CR-NF type equalizer circuit
Ultra-low noise, ultra-low distortion operational amplifier OPA1612A is used for the equalizer amplifier,
High quality audio op-amp MUSES 8820D is used for buffer amplifier.
Input impedance, input capacitance, and gain can be switched to match cartridge characteristics.
Two independent settings can be switched between MM/MC and MM/MC only by two independent setting switches.
±15V power supply circuitry that fully exploits the performance of the operational amplifiers.
Aluminum case

Instruction manual (with RIAA equalizer deviation and gain measurement values)
Input impedance, input capacitance, and gain can be set in detail.
This allows selection of more optimal setting values for various cartridges.
In addition, two independent setting values can be selected by using the setting selection switch on the front panel.
This allows not only MM/MC switching, but also the use of two systems of different specifications (MM only or MC only) by changing the settings of the internal DIP switches.
