The Pro-Ject Speed Box SE II provides quartz-generated and electronically regulated 33 and 45-RPM speed change specifically for most Pro-Ject turntables. Speed stability is a remarkable +/- 0.001% and pitch is variable +/- 20 in 0.1 r.p.m. steps. All functions are microprocessor controlled with a digital readout displaying the selected speed. A superior high-current outboard power supply is included.
Pro-Ject turntables sound great out of the box, but the Speed Box SE II offers an effective upgrade if you're looking to get a little more from your deck. First off, it allows you to switch between speeds with the push of a button, but most importantly, it reduces the speed variance of the record platter. This amounts to much more controlled and natural bass, heightened clarity through the mids, and tighter highs.
The Speed Box SE II works with any turntable that uses an AC synchronous motor.
