Product Information:

High End Features at an Affordable Price

The Phono Box S3 B is a phono preamplifier that offers a fully balanced design in a neat, small package. Pro-Ject have packed this tiny chassis to the brim with high-end features. One of those is their new True Balanced Connection. When used in combination with a Pro-Ject turntable with a 5-pin balanced output and 5P to XLR cable, you can achieve a totally balanced connection, minimising noise and delivering a breathtaking analogue signal.

Until now, balanced connections were exclusive to the RS range of products. The Phono Box S3 B brings those features to more affordable products.

Fully Discrete and Symmetrical Gain Stage

The new Phono Box S3 B gain stage uses a fully discrete layout. A discrete circuit is composed of disparate electronic components, and individual devices. The amplifier section is built of single parts and doesn‘t use any integrated circuits! That makes for an extended and more costly design process but results in the best sound quality. The fully symmetrical gain stage can optimise the signal-to-noise ratios, feeding the semi-passive, RIAA equalisation stage with a clean signal to work on.

Great pans for meal trains or prep
Size: 10P -9×13 In, Color: Silver
Great pans for delivering meals to people or prepping freezer food. Four stars because they are slightly smaller than a 9x13 pan, but they still work great for most recipes. They are much cheaper than the stores.

Reviews for this product were varied, but I decided to give it a go. A wise choice. These arrived on time, in a plastic bag, in a box, inside a sturdier box…in perfect condition. They are very sturdy compared to most I’ve seen. I used them in preparing a meal for a family who lost a loved one. If they easily accommodate 5 lbs of potato salad, I’d say they’re sturdy. I also used them for sliders, and a couple of fruit trays.
