Heritage Audio Lang silverr47 dual tube mic preamp

The LANG Electronics SILVERR 47 is a dual-channel tube microphone preamplifier featuring NOS 6AU6 pentode input valves, JJ E88CC output valves, and custom-designed input/output transformers from LANG ELECTRONICS Inc., offering up to +52dB of stepped gain with a variable output control and unique harmonic distortion capabilities.

The Rebirth of a Sonic Icon

The SILVERR 47 revives one of the most iconic preamp designs ever used, faithfully recreating the circuitry that defined the British Invasion sound of the 1960s. Far more than a vintage homage, this unit adapts the classic topology for modern studio needs, delivering exceptional warmth, presence, and harmonic character across a broad range of instruments and musical styles—from rock and hip hop to pop and electronic.

Precision-Engineered Components

Each channel incorporates a carefully selected NOS 6AU6 pentode in the input stage for detailed signal handling, paired with a JJ E88CC valve in the output stage to ensure smooth saturation and low noise performance. Custom input and output transformers—sourced and designed by Heritage Audio in collaboration with LANG ELECTRONICS Inc.—form the sonic backbone of the unit, ensuring faithful replication of the original preamp’s tone profile.

Distinctive Tonal Flexibility

The SILVERR 47 delivers +52dB of total gain in stepped 6dB increments, with a variable output control for fine-tuning levels and tone. An exclusive ‘NO FEEDBACK’ gain position introduces significantly elevated harmonic distortion, enabling engineers to sculpt unique textures previously unattainable in conventional designs. This functionality transforms the SILVERR 47 from a classic preamp into a creative sonic shaping tool.

Studio-Ready Versatility

Designed for full integration into professional setups, the SILVERR 47 features balanced XLR microphone inputs, balanced ¼" TRS line inputs, and a front-mounted ¼" TS direct injection input for instruments. From tracking vocals and instruments to driving EQ sections, fader stages, or acting as a line driver, it operates flawlessly across every stage of the signal chain.

A Legacy Reinvented

More than six decades after its original release, the SILVERR 47 channels the spirit of a revered sonic era while equipping today’s studios with the tools to shape tomorrow’s sound. A simple yet refined design, it embodies vintage character and modern reliability in equal measure.
