Crown Audio Macro-Tech 3600VZ Used, Second hand

Ref. code: 1.07.258

Macro-Tech 3600VZ


The Macro-Tech series is a complete family of amplifiers designed for pro sound reinforcement. Macro-Tech amplifiers are designed to provide enormous levels of pure, undistorted power in a rugged low-profile package, utilizing Crown`s patented Grounded Bridge output topology. They also employ Crown`s patented ODEP protection circuitry, which keeps the amplifi er working under extreme conditions that would shut down a lesser amplifi er. The MA-3600VZ features Crown`s PIP (Programmable Input Processor) expansion system. The PIP expansion system makes it easy to tailor the amplifier to a specific application. Providing high power amplifi cation from 20 Hz to 20 kHz with minimum distortion, Macro-Tech series amplifiers feature balanced inputs with bridged and parallel monophonic capability. Specific features vary depending on model.

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.
