– The input stages used in the Black Cube Decade

can also be found in top notch mixing consoles or 

in well known professional  microphone preampsli-

fiers.

– The passive filter network between two linear gain 

stages realized with high precision MKP caps (Epcos)

– Several resistive and capacitive loads as standard

– Front switchable gain (36dB – 66dB) and Soft- 

Bass-Rollof (6dB/oct. 60Hz)

– Onboard slot for custom impedance

– Zero global feedback Class A output stage technically identical with the highly acclaimed Black Cube 

Linear.

– LCL Pi-filter in the power supply section of the ÁUDIO board for optimal suppression of radio frequent 

intermissions

– High quality gold plated pcb mount RCA connectors for audio.

– High quality double sided printed circuit board for 

optimal signal routing and component placing.

– Neutrik connector with gold plated contacts for 

supply connection (as with the Silver Cube

– Face plate anodized aluminium either black or silve

– 30 VA toroidal transformer of the PWX II power 

supply is a key component for the sonic performance achieved with the Black Cube Decade. This 

transformer is not only overdimensioned but  sports 

a grounded isolation coil between the primary and 

secondary coil. 

– Only Low-ESR electrolytic capacitors are used

– Neutrik connectors with gold plated contacts for 

supply connection (as with the Silver Cube).

– Chokes before and after the voltage regulation

– Downward compatible with PWX: Black Cube SE 

ÁUDIO sections can be connected. Black Cube standard versions can be upgraded with an XLR plug.

– High quality double sided printed circuit board for 

optimal signal routing and component placing.

– Double sided board for optimum parts placement 

and trace routing

– Face plate anodized aluminium either black or silver
