A major strength of the 310LP is its highly configurable nature. There are numerous end-user adjustments for resisitance loading, capacitance loading and gain level. Going one step further, you can even chose from two different equalization curves - either the RIAA curve or the IEC curve.
The Pro-Ject Phono Box DC is a flexible phono stage for interfacing a turntable to a preamplifier, integrated amplifier or receiver that provides only line-level inputs. Low noise, lose distortion and a flat RIAA equalization curve with 60dB of gain (MC), 40 dB gain (MM) deliver high fidelity performance for both moving magnet and moving coil cartridges. The Phono Box DC is capable of a maximum output of 9.5V RMS / 1 khz.
