Add More Inputs to Your Preamp or Amp
Add addition inputs to your Pro-Ject Pre Box S compact stereo preamplifier with the Pro-Ject Switch Box S. It's a great way of adding extra inputs to other manufacturers' components, too.
Operation of the Switch Box S is particularly convenient when used with the Pro-Ject Pre Box S. It provides three-input expansion and offers automatic synchronization with the trigger cable of the Pre Box S.
The metal case helps shield the electronics from vibration and electromagnetic interference. The outboard power supply keeps the chassis size small. |
