Pro-Ject Phono Box E BT5 white

The Pro-Ject Phono Box E BT5 is an innovative phono preamplifier designed for modern vinyl enthusiasts. This compact little device offers a versatile solution for connecting a turntable to an audio system, whether through traditional wired connections or wirelessly via Bluetooth. Combining classic features with cutting-edge technology, it aims to meet the needs of today’s audiophiles.

A Phono Preamp with Multiple Talents

The Phono Box E BT5 stands out for its versatility. It can be used as a classic phono preamplifier for moving magnet (MM) cartridges, connecting to a hi-fi amplifier via its analog line output. However, its standout feature is its ability to convert analog signals into digital for wireless transmission via Bluetooth. This functionality allows you to stream the sound from a turntable to Bluetooth-compatible speakers, headphones, or other devices, offering great flexibility in setup.

Advanced Bluetooth Technology for Preserved Audio Quality

Pro-Ject has equipped the Phono Box E BT5 with the latest advancements in Bluetooth transmission. It features Bluetooth version 5.2, ensuring a more stable connection and an extended range of up to 10 meters. Support for aptX, aptX HD, and aptX Adaptive codecs enables high-quality audio transmission, comparable to a wired connection. These advanced codecs significantly reduce signal compression, preserving the sonic nuances cherished by vinyl enthusiasts.

Audiophile Design in a Compact Format

Despite its small dimensions (120 x 32 x 100 mm), the Phono Box E BT5 makes no compromises on build quality. Its metal casing provides effective protection against electromagnetic interference. Inside, additional metal shielding and carefully selected low-noise components help maintain the purity of the audio signal. Gold-plated connectors ensure optimal and durable connections.

Flexible Connections to Suit Any System

The Phono Box E BT5 features two distinct inputs: a phono input with RCA connectors for the turntable and a line input with a 3.5mm mini-jack for connecting other analog sources. This dual input allows the device to function as a universal Bluetooth transmitter for any analog source. On the output side, there’s an analog line output via a 3.5mm mini-jack in addition to the Bluetooth output, enabling simultaneous use of both.

Precise RIAA Equalization for Authentic Sound

One of the essential functions of a phono preamplifier is to apply RIAA (Recording Industry Association of America) equalization. The Phono Box E BT5 excels in this area with a precision of ± 0.5 dB between 20 Hz and 20 kHz. This accuracy ensures faithful reproduction of the sound etched into the vinyl, respecting the tonal balance intended by the sound engineers during the record’s production.

An Ideal Companion for Modernizing a Vinyl Setup

The Phono Box E BT5 is particularly appealing for those looking to modernize their vinyl setup without replacing all their equipment. For example, it allows you to connect an older turntable to modern wireless speakers or listen to your records with wireless headphones. This versatility makes it an excellent tool for adapting your hi-fi system to new listening habits.

Sleek Design Available in Two Colors

Pro-Ject offers the Phono Box E BT5 in two finishes: black or white. The white model, featured in this presentation, boasts a minimalist and elegant design that easily blends into any interior. Its simple front panel includes just one button and an LED indicator for maximum ease of use.
