PL236
The PowerLight 2 Series is a high performance line of amplifiers designed exclusively for the touring and live sound professional. Four models range in power from 900 watts to 1850 watts per channel, all in two-rack space chassis that are only 14" deep and 21 lbs. Each of these models is available in two versions: a base model and an "A" version. Base models are ideal for systems using external signal processing. For those looking for integrated solutions, "A" versions offer internal analog signal processing. Full DSP capabilities may also be added to any model with the addition of the DSP-3 Module.
With PowerWave technology, PowerLight 2 amplifiers take your sound to a whole new level. Not only does it give you tighter bass and clean transparent highs, PowerWave also cuts waste heat, boosts reliability and gets rid of unwanted noise and hum. PowerWave is a revolutionary switching power supply technology that provides ample current to the audio power circuitry by charging the supply rails 230,000 times a second through an ultra-low impedance circuit. So unlike amplifiers that use conventional supplies, the audio signal is never starved prematurely and remains crisp and clean.
Through continued improvement and innovation, QSC’s new PowerLight 2 offer features not found in any other professional audio amplifier.

Used QSC Audio
QSC is an American manufacturer of audio products including power amplifiers, loudspeakers, digital mixers and digital signal processors including the Q-Sys networked audio, video and control platform.
QSC products are used by professional installed, portable, production, corporate and cinema customers worldwide.
The company was founded in 1968 by Patrick Howe Quilter, who serves as chairman of the board of directors.
Quilter was at the time an engineering student with a keen interest in electronics and music.
In 1967 Quilter had learned that the bass player in his brother’s high school band was searching for an affordable bass amp.
At first the company was a storefront operation in Costa Mesa, California, a combination of manufacturing and retail operations under one roof. The amplifiers were built in the back and sold out front. The first employees were mostly friends helping out.
The early guitar amplifiers bore names like the Duck Amp and the Quilter Sound Thing.
The company adopted the name Quilter Sound Company, which was eventually shortened to the initials "QSC" and was known as QSC Audio Products, Inc. for many years.
The company was officially renamed QSC, LLC in 2015.

Efficiency Rating: Level of sound output measured at a prescribed distance with a standard input power. Efficiency rating standard is 1 watt (2.83V at 8 ohms) at 1 meter over a specified frequency range and is measured in decibels.
Equalization: Loosely, any type of relative frequency adjustment. Specifically, the process of changing the frequency balance of an electrical signal to alter the acoustical output.
Equalizer: A component designed to alter the frequency balance of an audio signal. Equalizers may be graphic, parametric, or a combination of both.
Fade: A gradual increase in audio, i.e. a fade-up, or a gradual decrease in audio, i.e. a fade-down.
Feedback: The transmission of current or voltage from the output of a device back to the input, where it interacts with the input signal to modify operation of the device. Feedback is positive when it’s in phase with the input and negative when it's out of phase.
FM: Frequency Modulated.
Frequency: The number of cycles (vibrations) per second. In audio, audible frequencies commonly range from 20 to 20,000 cycles per second (Hz). In video, frequency is used to define the image resolution. Low-frequency video images depict large objects or images. Higher frequencies depict smaller objects (finer details.
Frequency Response: A measure of what frequencies can be reproduced and how accurately they are reproduced. A measurement of 20 to 20,000 Hz, 3dB means those frequencies between 20 and 20,000 Hz can be reproduced no more than 3 dB above or below a reference frequency level.
Full-Range: A speaker designed to reproduce the full range (20 Hz to 20 kHz) of audio frequencies.
Gain: Increase in level or amplitude.
Gooseneck: This refers to a microphone with a flexible neck that is most frequently attached to a podium or lectern. It is designed to allow the speaker to raise or lower the microphone to a suitable height.
Graphic Equalizer: A type of equalizer with sliding controls that creates a pattern representing a graph of the frequency-response changes. Raising sliders boosts the affected frequencies lowering sliders cuts (attenuates) the affected frequencies.
HDCP: High-Bandwidth Digital Content Protection. Created by Intel, HDCP is used with HDTV signals over DVI and HDMI connections and on D-Theater D-VHS recordings to prevent unauthorized duplication of copyright material.
HDR: Hard-Drive Recorder. Device that uses a computer hard drive to store compressed digital audio and video signals.
High Pass: A filter that passes high frequencies, and attenuates low frequencies. Same as low cut.
Hz: Hertz or cycles per second. Something that repeats a cycle once each second moves at a rate of 1 Hz.
Incue/Inq/In-Point: These words all refer to the initial few seconds of audio signifying the beginning of the production.
Integrated Amplifier: A combination preamp and amplifier.
Impedance: A measure of the impediment to the flow of alternating current, measured in ohms at a given frequency. Larger numbers mean higher resistance to current flow.
KHz: Kilohertz or one thousand Hz.
Lavaliere: A small microphone that attaches to clothing, allowing the speaker to have a hands-free presentation.
Line Array: A group of speakers that have been arrayed or ” built up” in the vertical or horizontal plane, which allow for a highly consistent sound field. A Line Array is perfect for medium to large audiences.
Line-Level (Low-Level): A level of electrical signals too low to make the average speaker move sufficiently. Amplifiers receive line-level signals and amplify them to speaker level.
lockout: The final words of a segment used to signify the production’s conclusion.
Low Pass: A filter that lets low frequencies go through but doesn’t let high frequencies go through. Same as high cut.
MHz: Megahertz, or 1 million Hz.
Midbass: The middle of the bass part of the frequency range, from approximately 50 to 100 Hz (upper bass would be from 100 to 200 Hz). Also used as a term for loudspeaker drivers designed to reproduce both bass and midrange frequencies.
Midrange: The middle of the audio frequency range. Also used as a term for loudspeaker drivers designed to reproduce this range.
Mixer: This is the unit in which audio signals are directed from. A mixer provides for both mic and line input combinations while allowing you to control one or more outputs.
MLP: Meridian Lossless Packing. Encoding format that is able to completely reconstruct the original signal at the receiving end. No information is lost or discarded, regardless of how trivial it might be. Used to encode six channels of high-resolution audio on DVD-A.
Mono: Monophonic sound. One channel.
MP3: MPEG-1 Audio Layer-3. Compression scheme used to transfer audio files via the Internet and store in portable players and digital audio servers.
Natural Sound (NATS): The nonverbal audio that occurs in a non-studio setting. NATS can be used to help characterize the setting.
Noise: An unwanted portion of a signal such as hiss, hum, whine, static, or buzzing.
Nonlinear Editing: Digital audio systems that allow for clips to be extracted without affecting the master recording.
