Lehmann Audio Black Cube Phono Stage
The Lehmann Audio Black Cube phono stage is compatible with practically all available cartridges on the market from High Output MM to MC. Apart from the standard switch settings there is one onboard slot that can be fitted with a custom impedance to supply perfect termination even for the most exotic cartridges.
Amplification and RIAA equalisation for MM and MC cartridges
Premium components
High end Burr Brown gain stage
Small size allows installation close to record player
Metal case shields the electronics from vibrational and electromagnetic interference
2x RCA input / 2x RCA output

The input stages used in the Black Cube can also be found in top notch mixing consoles and in well known professional microphone preamps. The entirely passive RIAA equalization network is realized with high precision foil capacitors. All resistors are of the low noise metal film variety. The switches for gain and load settings have gold plated contacts.
Because of the small outer dimensions the Black Cube can be placed next to the turntable. This minimizes loss due to cable lengths. The low noise regulated external power supply is connected permanently to the audio section to minimize the number of contacts in the signal path.
Lehmannaudio always pays special attention to details: the cable between the power supply and audio section is shielded. The cases of both the power supply and the audio section are made of nonmagnetic materials and the case of the audio section is even equipped with a top cover coated with a special anti-resonance treatment.
