Cartridge loading options

Large ranges from 40dB up to 65dB are possible. A fully balanced design makes all the difference here. You can perfectly match it with a wide variety of cartridges and integrate it into the rest of your HiFi system, matching the volume levels accurately to other sources like CD players or streaming devices. Ultra low values like 50 pF or 10 ohms allow you to account for special situations, for example sub-ideal higher capacitance cables. Each input settings are stored in the memory.
