Concert Sound Reinforcement Systems

A sound reinforcement system is the combination of microphones, signal processors, amplifiers, and loudspeakers that makes live or pre-recorded sounds louder and may also distribute those sounds to a larger or more distant audience. In some situations, a sound reinforcement system is also used to enhance the sound of the sources on the stage, as opposed to simply amplifying the sources unaltered. A sound reinforcement system may be very complex, including hundreds of microphones, complex mixing and signal processing systems, tens of thousands of watts of amplification, and multiple loudspeaker arrays, all overseen by a team of audio engineers and technicians. On the other hand, a sound reinforcement system can be as simple as a small PA system in a coffeehouse, consisting of a single microphone connected to a self-powered 100-watt loudspeaker system. In both cases, these systems reinforce sound to make it louder or distribute it to a wider audience.

Disc Jockey

A disc jockey, also known as DJ (or deejay), is a person who selects and plays recorded music for an audience. Originally, disk referred to phonograph records, while disc referred to the Compact Disc, and has become the more common spelling. Today, the term includes all forms of music playback, no matter the source.

There are several types of disc jockeys. Radio DJs introduce and play music that is broadcast on AM, FM, shortwave, digital, or internet radio stations. Club DJs select and play music in bars, nightclubs, discothèques, at raves, or even in a stadium. Hip hop disc jockeys select and play music using multiple turntables, often to back up one or more MCs, and they may also do turntable scratching to create percussive sounds. In reggae, the disc jockey (deejay) is a vocalist who raps, "toasts", or chats over pre-recorded rhythm tracks while the individual choosing and playing them is referred to as a selector.[1] Mobile DJs travel with portable sound systems and play recorded music at a variety of events.

  is a form of interactive entertainment or video game in which amateur singers sing along with recorded music (and/or a music video) using a microphone and public address system. The music is typically a well-known pop song minus the lead vocal. Lyrics are usually displayed on a video screen, along with a moving symbol or changing color and/or music video images, to guide the singer. In some countries, a karaoke box is called a KTV. Due to its English pronunciation, it is sometimes incorrectly spelled "kareoke". It is also a term used by recording engineers translated as "empty track" meaning there is no vocal track.

 Crown Micro-Tech 600 Rack Mount 2-Channel 600W Power Amplifier MT600

Crown's first touring workhorse, the Micro-Tech Series, delivers industry standard performance and reliability. 

Able to drive low-impedance loads with ease, Micro-Tech amplifiers feature three separate power supplies for exceptional reliability and impressive power ratings. Our patented ODEP circuitry keeps the amplifier working long after others would quit. Grounded bridge circuitry doubles the available voltage without placing output transistors in stressful configurations like other more conventional amplifiers. The unique forced-air cooling system makes certain heat is dissipated quickly and evenly. As a result, you get maximum performance without the threat of damage to the amplifier or other system components.

FTC Continuous Average Power from 20 Hz to 20 kHz with No More than 0.1% THD:

Micro-Tech 600: 600 watts into 8 ohms, 885 watts into 4 ohms.

Rane GE27 Graphic Equalizer EQ Single Channel Ge-27
The GE 27, a single Channel, 27-band, 1/3-octave version. Housed in two rack-space units, these equalizers feature long throw, high resolution slide controls on each band, ensuring good resolution over its extended boost/cut range of +12dB to -15dB.
The active filter sections are of the constant bandwidth (constant-Q) variety. The bandwidth of each individual filter is guaranteed to be narrow enough to prevent unwarranted interaction between filters, yet wide enough to produce exactly the type of correction curve demanded by even the most unusual acoustic surroundings. This differs dramatically from conventional designs of the past encumbered with the unfortunate characteristic of changing bandwidth with changing boost/cut amounts.
Front panel controls and indicators include an overall LEVEL control for each Channel as well as Signal present and Overload indicators. The rear of the unit provides ¼" TipRing-Sleeve connectors for Inputs and Outputs. The Inputs are fully actively balanced: the tip is the positive input, the ring negative and the sleeve is signal ground. Unbalanced sources may be connected to the GE series through the use of either 'mono' ¼" connectors or by tying the ring to the sleeve on TRS type plugs. The outputs are active unbalanced.
