Pro-Ject Optical Box E RIAA amplifier (MM)

Highlights
• Optical and analogue signal output
• Can function as a signal splitter or input extension
• Digitizer for both phono and line signals
• Precise A/D conversion with 24-bit / 96kHz resolution
• Internal metal lining eliminates RF interference and vibration

The Optical Box E Phono is the ideal choice for anyone who wants to use their turntable with devices that only have digital inputs, such as home theater receivers, soundbars or all-in-one systems. The optical box E Phono takes many needs into account and offers a digital-optical signal output as well as a standard analog output that work simultaneously. Therefore, it can be used as the perfect signal splitter 1>2 to play the same signal on 2 systems simultaneously. Another very useful feature of the Optical Box E Phono is that it can act as an input expander for a system lacking inputs. Last but not least, the Optical Box E Phono can digitize not only phono sources, but also line signals from tape recorders, tuners, etc. To ensure that the incoming signal is maintained as pristine as possible, the high-precision A/D conversion is performed with 24 -bit / 96kHz resolution.
Of course, it can also be used as a regular MM phono preamplifier with line output (3.5 mm jack) to be integrated into any HiFi system. The interior of the housing is lined with metal, which eliminates RF interference and vibrations, ensuring an undisturbed listening experience. The Optical Box E Phono is the perfect partner for all modern audio enthusiasts who want to use their analog signal sources with digital or analog playback devices!
