With the 7U 4 Zone CaseMake Noise presents the successor of the popular 7U CV Bus Case. On two rows of 104 HP each, the Case offers space for 3U Module as well as another row containing the revised CV Bus. The powerful power supply unit powers the Case and delivers +12 V: 4000 mA / -12V: 2000 mA / 5V: 1000 mA; for Module there are 34 connectors, one of which is reserved for the CV Bus. The maximum installation depth is 63 mm. The case itself impresses with a high-quality finish with powder-coated surface, rubber feet and a removable lid. The lid is high enough to transport the Case patched when closed. The manufacturer has paid special attention to the development of the 4 zone busboard. The 34 connections are divided into four zones (8, 9, 9, 8 connections) that are isolated from each other and supply +12 V: 1000 mA / -12V: 500 mA per zone; the 5V rail goes to all zones with a total of 1000 mA. Even the ground return path is derived individually per zone.
The Utility series with CV Bus
The highlight of the 7U 4 Zone Case is of course the Utility row, which has been revised in parts. Most of the space is taken up by the CV Bus, which consists of four colour-coded 1 on 4 (1 In/4 Out) buffered multiples. The CV Bus distributes clock, gate, trigger and control voltages to up to four destinations per bus and gives visual Feedback about the signal. To the left of the CV bus is the Voltage Math, a useful tool for editing voltages. The two inputs are summed at the output, with the lower one set to Unity and the upper one adjusted by the bipolar attenuator. The attenuated input is also normalized to a DC offset to allow for level shifting, voltage inversion, etc. The output level and polarity is indicated by the green and red LEDs. To the right of the CV bus is the stereo line driver, which converts the powerful signal to line level at Eurorack level. On the input side, mono and stereo signals are accepted, which are output in stereo at the outputs and at the headphone output. To avoid overloads, an overload indicator is implemented for the left and right channel.
