The Black Case features two 3U rows with 104 HP each. The KAZU power module is installed on one side panel of the case. Thus, it does not occupy any of the valuable HPs. For distributing power, an EVE 1 low-impedance bus board is built-in. Up to 20 modules can be connected. Although the Black Case is completely made of wood, it weighs only 4.5 kilos. – Hardly more than an aluminum case. Only few parts are made out of metal. Thanks to the handle and a lid, the case is easy to transport. Rubber feet ensure a secure stand in upward and horizontal position. The gap dimensions may not be 100 % perfect, as used from machine-made plastic bombers. – That’s the price for having a one-of-a-kind case made with love in Berlin
Information on the KAZU power module:
KAZU is a switching power supply developed especially for modular systems. Thanks to extremely low interferences and voltage spikes, modules connected to this PSU sound crystal clear. It is also worth mentioning that the KAZU hardly warms up. – Even while being used close to maximum capacity. It goes without saying that a power supply such as this one is protected against short circuits and over-voltages.
- +12 V: Regulated, filtered, less than 2 mV fluctuations and noise at full capacity, typically 1.5 mV.
- -12 V: Regulated, filtered, less than 2 mV fluctuations and noise at full capacity, typically 1.5 mV.
- + 5 V: Unregulated, filtered, less than 40 mV fluctuations and noise at full capacity, typically 30 mV.
Maximum voltage output:
- 1000 mA at +12 V
- 1000 mA at -12 V
- 500 mA at +5 V
Information on the EVE 1 bus board:
EVE 1 features exceptionally low transition resistances between PSU and modules. Crosstalk was almost completely eliminated. This is achieved by using six layers of conductive tracks, which stretch over the entire circuit board. For +12 V, -12 V and +5 V, there is one copper plane each. Ground features three layers. High-precision buffer capacitors enhance the low-noise design even further.
EVE 1 is equipped with 20 polarity protected module connectors, divided into two separate lines of ten sockets each. Shielded CV and gate channels according to the Doepfer standard can be (de)activated via jumpers. Connection to the KAZU is established by a five-pin socket.
