Lehmann Audio Black Cube Se II Phono Preamplifier

Lehmann Audio Black Cube Se II Phono Preamplifier

High-Performance Mm/Mc Phono Stage With External Pwx Power Supply

The Lehmann Audio Black Cube SE II is a high-performance MM/MC phono preamplifier designed for serious analogue playback systems. Based on the proven Black Cube SE audio architecture, it combines ultra-low-noise amplification, extensive cartridge matching flexibility and a powerful external PWX power supply to deliver greater authority, dynamics and musical expression from vinyl playback.

Designed for demanding audiophile systems, the Black Cube SE II supports a wide range of moving-magnet and moving-coil cartridges through four selectable gain settings, multiple input impedance options and advanced custom loading configurations. Its extensively adjustable bass filter allows the low-frequency response to be tailored to the specific cartridge, record collection and listening environment.

Designed For Serious Analogue Systems

The phono stage is one of the most important components in a vinyl playback system. The tiny signal generated by a cartridge must be amplified and accurately matched before it can be passed to a line-level amplifier.

The Black Cube SE II is designed to provide the gain, loading flexibility and low-noise performance required by a wide range of modern and classic MM and MC cartridges. Its carefully engineered architecture is designed to preserve the dynamics, tonal character and musical information contained in the original recording.

Powerful External Pwx Power Supply

A key feature of the Black Cube SE II is its dedicated external PWX power supply. By separating the power supply from the sensitive audio circuitry, the design helps provide a clean operating environment for the phono stage.

The external PWX power supply is engineered to provide a generous power reserve, supporting the Black Cube SE II's ability to reproduce demanding musical passages with authority, control and dynamic expression.

Flexible Cartridge Matching

Different cartridges require different gain and electrical loading conditions. The Black Cube SE II provides four selectable gain levels and multiple input impedance options to support a wide range of MM and MC cartridge designs.

Advanced users can also make use of the custom load slot and hardwire slot for specialist cartridge matching applications. This level of flexibility allows the phono stage to be configured around the specific requirements of a cartridge and tonearm combination.

Extensively Adjustable Bass Filter

The integrated bass filter provides sixteen different settings between approximately 7 Hz and 90 Hz. This allows the low-frequency response to be adjusted according to the requirements of the cartridge, record collection and listening environment.

The adjustable filter can also help manage unwanted very-low-frequency energy while maintaining the musical integrity of the audible bass range.

Low-Noise, High-Resolution Performance

The Black Cube SE II is designed for clean and detailed analogue reproduction. Its carefully engineered audio circuitry is intended to preserve low-level musical information while maintaining a quiet background.

The combination of low noise, flexible gain settings and precise cartridge loading allows the phono stage to extract a high level of detail and dynamic expression from both MM and MC pickup systems.

Premium Construction

The Black Cube SE II combines a compact audio section with a separate PWX power supply and a premium front-panel design. It is available in aluminium, black aluminium and chrome finishes.

Its compact dimensions allow it to integrate easily into a wide range of high-end stereo systems while maintaining the understated, precision-engineered appearance associated with Lehmann Audio products.
