Monday, March 28, 2011Optimizing Your System: In-Depth Look At Instrument Cable
PSW Staff 03/28/11 10:16 AM, 0 CommentsAre instrument cables used for high-impedance or low-impedance lines? Generally, the source impedance is the determining factor in cable selection. Instrument cables are used for a wide range of sources. Many keyboard instruments, mixers, and signal processors have very low (50 to 600 ohm) source impedances. On the other hand, typical electric guitar or bass pickups are very inductive, very high impedance (20,000 ohms and above) sources. Typical load impedances are greater than 10,000 ohms, which limits the electrical current… View this post

Pat Brown 03/25/11 09:15 AM, 0 CommentsLife is all about circuits. In hydraulic circuits, a pump forces a fluid to flow, such as water through pipes or soda through a straw. In pneumatic circuits, a pump forces airflow down a path, such as the air conditioning system in your house or the air hose that you use to inflate your tires. We all know intuitively that pumps produce a pressure and rate-of-flow of something. A path must exist for the flow to follow, whether intentional (electrical… View this post

Thursday, March 24, 2011Addressing The Myths of Wireless System Transmitter Power
Mike Wireless 03/24/11 01:38 PM,One of the topics that I’ve seen poorly understood, and even deliberately used to mislead people, is the issue of wireless microphone transmitter power and the effects said power has on system performance. Let’s start with the basics: all things being equal, more transmitter power = more range for the system, but not in a linear way. In broad terms, when discussing analog wireless systems, the receiver wants to see a signal from a transmitter that is at least about… View this post
