Description Pro-Ject MC Step Up Box S3 Step-up Transformer The Pro-Ject MC Step Up Box S3 Step-up Transformer is the perfect addition. We always recommend a step-up transformer in combination with a high quality MM phono (especially tube) preamp, rather than MC phono preamplifiers. View Manual >> View Product Information >> View Pro-Ject Audio Products >> Features Lively, dynamic & natural The MC Step Up Box S3 works very differently compared to a phono preamplifier. The windings ratio of the transformer determines the gain factor. As it works completely passive and no external power is needed, no extra power can be produced. The increase in voltage is achieved by a coresponding decrease is current. As there is no amplification, the MC Step Up Box S3 has a remarkable noise performance and a very low level of distortion. The sound with a Step-Up Transformer will be more lively, dynamic and natural. Gold plated Premium RCA terminals – Gold plated in- and output RCA terminals for optimum signal transmission. Solid full aluminum housing – Due to the timeless design & rigid aluminum casework, the MC Step Up Box S3 is built for eternity. Cartridge impedance setting – Cartridge impedance matching button on the back. Two different settings available: 10-40Ω & 40-150Ω Made in EU With High-quality materials – The new Step Up Box S3 is carefully designed and handmade in Europe. Specifications Frequency response 10Hz – 55kHz: /- 1dB Gain at 10-40 Ohm: 21dB at 1kHz Transformation ratio: 1:16 Gain at 40-150 Ohm: 24dB at 1kHz Recommended load: 47 kOhm / 100pF Input MC: 1x pair RCA phono sockets Output: 1x pair RCA phono sockets Dimensions WxHxD: 206 x 65 x 153 (164 with sockets) mm Weight: 940g
