Pro-Ject Speed Box S Pro-Ject speed controller

The Pro-Ject Speed Box S Pro-Ject speed controller is replaced by the Pro-Ject Speed Box S2 speed controller.

The new Speed Box S replaces the famous Speed Box 2. It is ideal for entry-level and midrange vinyl turntables with a synchronous motor operating with a 16 V DC voltage. The latest variant features a new 18 V DC power supply unit. 

It comes in a non-magnetic metal housing with an aluminium front fascia. It includes a pulse switch for the selection of the playback speed (33/45 rpm) as well as two LEDs showing the active selection.

Its prime purpose is to allow (by changing the frequency) to change the speed of the motor and, therefore, to switch from 33 rpm to 45 rpm without going through the hassle of manually changing the belt from one pinion to the other (and not lifting the platter!). Very handy for those of you who own a collection of singles! However, it is not its sole purpose, because its quartz generator and microcontroller ensure an amazing stability for the motor rotation. Its precision of 0.001% leads to 5-fold speed stability. 

We soon connected it to a Pro-Ject 1-Xpression and 2-Xperience turntable. The results were quite convincing and seemed to exceed the previous version on all accounts: dynamics, transparency, finish of the note... The improvement in musicality is undeniable and the comfort of use make it essential!

Highly recommended with Debut 3, Essential 1, Genie 1.3, XPression II, III, RPM 4 and RPM 5, XPerience.
