An audio power amplifier is an electronic amplifier that amplifies low-power electronic audio signals, such as the signal from a radio receiver or an electric guitar pickup, to a level that is high enough for driving loudspeakers or headphones. Audio power amplifiers are found in all manner of sound systems including sound reinforcement, public address, home audio systems and musical instrument amplifiers like guitar amplifiers. It is the final electronic stage in a typical audio playback chain before the signal is sent to the loudspeakers.
A mixing console or mixing desk is an electronic device for mixing audio signals, used in sound recording and reproduction and sound reinforcement systems. Inputs to the console include microphones, signals from electric or electronic instruments, or recorded sounds. Mixers may control analog or digital signals. The modified signals are summed to produce the combined output signals, which can then be broadcast, amplified through a sound reinforcement system or recorded.

A stage box is an interface device used in sound reinforcement and recording studios to connect equipment to a mixing console. It provides a central location to connect microphones, instruments, and speakers to a multicore cable (snake), which allows the sound desk to be further from the stage and simplifies setup.

The Technology and Engineering Emmy Awards, or Technology and Engineering Emmys, are one of two sets of Emmy Awards that are presented for outstanding achievement in engineering development in the television industry. The Technology and Engineering Emmy Awards are presented by the National Academy of Television Arts and Sciences (NATAS), while the separate Primetime Engineering Emmy Awards are given by its sister organization the Academy of Television Arts & Sciences (ATAS).
Harrison Audio Consoles is an international company based in Nashville, Tennessee that manufactures high-end mixing consoles, Digital Audio Workstations (DAW), audio plugins, and other audio technologies for the post-production, video production, broadcast, sound reinforcement and music recording industries. The company is renowned as an industry innovation for its "in-line" mixing console design that has subsequently become the standard for nearly every large-format music console. Over 1,500 Harrison consoles have been installed worldwide, presenting a significant percentage of the overall world market share for high-end audio consoles. The company founder, Dave Harrison, was inducted as a Fellow in the Audio Engineering Society for this technical contribution of the recording industry and in particular the first 32-bus "in-line" console.
In professional audio, a digital mixing console (DMC) is a type of mixing console used to combine, route, and change the dynamics, equalization and other properties of multiple audio input signals, using digital signal processing rather than analog circuitry. The digital audio samples, which is the internal representation of the analog inputs, are summed to what is known as a master channel to produce a combined output. A professional digital mixing console is a dedicated desk or control surface produced exclusively for the task and is typically more robust in terms of user control, processing power and quality of audio effects. However, a computer can also perform the same function since it can mimic its interface, input and output.
The Yamaha M7CL is a digital mixer that was manufactured by Yamaha Pro Audio. Two models with onboard analog input exist: the M7CL-32 and M7CL-48. These models have 40 - and 56 -input channels respectively, counting mono channels. Mixes, masters, groups, DCAs and individual channels can then be routed to an output via any number of the board's 16 configurable output XLR ports. The eight faders of the master control section can control multiple functions by way of "layers" in the same manner as the Yamaha PM5D. The board features Yamaha's "Selected Channel" technology, and Centralogic, unique to the M7CL. It can be augmented with more inputs or outputs via expansion cards, and can be fitted with third-party cards such as ones made by Aviom (A-Net), AuviTran (EtherSound), Audinate, AudioService (MADI), Dan Dugan (automixer), Riedel Communications (RockNet), Waves Audio, and Optocore. The M7CL-48ES recently joined the line-up with built-in EtherSound for digital networking using EtherSound stage boxes.

Smaart is a suite of audio and acoustical measurements and instrumentation software tools introduced in 1996 by JBL's professional audio division. It is designed to help the live sound engineer optimize sound reinforcement systems before public performance and actively monitor acoustical parameters in real time while an audio system is in use. Most earlier analysis systems required specific test signals sent through the sound system, ones that would be unpleasant for the audience to hear. Smaart is a source-independent analyzer and therefore will work effectively with a variety of test signals including speech or music.
Bruce Robert Jackson was an Australian audio engineer who co-founded JANDS, an Australian audio, lighting and staging company. He joined American touring audio engineer Roy Clair and mixed concert stage monitors for Elvis Presley in the 1970s. With Clair Brothers, a concert sound company, Jackson designed audio electronics including a custom mixing console. Beginning in 1978, Jackson toured as Bruce Springsteen's band engineer for a decade, using Clair Brothers sound systems. A business interest in Fairlight CMI in Sydney introduced Jackson to digital audio, and he subsequently founded the digital audio company Apogee Electronics in Santa Monica, California, where he lived at the time. After selling his share of Apogee, Jackson co-founded with Roy and Gene Clair a joint venture which produced the Clair iO, a loudspeaker management system for control of complex concert sound systems. Jackson turned the venture commercial with the help of Dave McGrath's Lake Technology. Dolby Laboratories bought the technology and formed Dolby Lake with Jackson as vice president, then in 2009 Lab.gruppen acquired the brand. Jackson was honoured with the Parnelli Innovator Award in 2005 for his inventive loudspeaker controller.
