All you need to know about good acoustics and sound systems in performance and worship spaces! Everyone knows that the ability to hear music in balance and to understand speech is essential in any space used for performance or worship. Unfortunately, in the early 21st century, we find that buildings with good acoustics are the exception rather than the rule. Much of the fault leading to this result can be traced to the widespread perception that acoustics is a black art. In fact, scientific acoustics as developed in the last century is a well-defined engineering practice that can lead to predictable excellent results. A basic, non-engineering understanding of acoustics will help building owners, theater managers, ministers and teachers of music, performers, and other professionals to achieve their goals of excellent acoustics in venues with which they work. Performers having a basic understanding of acoustics will be able to make the most of the acoustics of the venue in which they perform. This book helps those responsible for providing good acoustics in performance and worship spaces to understand the variables and choices entailed in proper acoustic design for performance and worship. Practicing acoustical consultants will find the book a useful reference as well. The level of presentation is comfortable and straightforward without being simplistic. If correct acoustical principles are incorporated into the design, renovation, and maintenance of performance and worship venues, good acoustics will be the result.

The Eurorack Stripboard is the most convenient way to build a simple DIY Eurorack synthesizer module. It works like a standard protoboard, but with specific additions for the Eurorack format. You can also use the Stripboard with the 4HP Front Panel. You can place up to 5 potentiometers or 5 jack connectors on the dedicated locations. The potentiometers can be any of 9 or 16 mm types, Alpha PKN160 for example. The Jack connectors are Cliff S6/BB mono style. With the Eurorack power supply interface, it's extremely easy to connect either a 16-pin or a 10-pin Eurorack power connector. The clear and detailed silkscreen labels indicate where the different voltages are located on the PCB. You can also add 2 filtering capacitors and 2 protection diodes. How to connect jacks and potentiometers The jack connectors are Cliff CL1384. They use the strips A, B, D and E. A and B are switched open when the male jack connector is inserted. D and E are the contacts to the male connector. E is Tip (the signal) and D is Ring (usually the 0V reference, often designated as “ground”). Note that Cliff jacks are insulated from the panel. The potentiometers are 9 mm (2.5 mm pin pitch) or 16 mm (5 mm pin pitch). Alpha 9 mm are a good choice. They align pretty nicely with Cliff jacks on the front panel. They connect to strips B, C and D. B is Counter Clock Wise pole. D is Clock Wise pole. and C is Wiper pole. Dimensions The PCB is 100 mm high and 50 mm wide. Thus, the depth for the Eurorack module will be 50 mm behind the panel. Downloads Documentation DIY Layout Creator
