Meyer Sound 1100-LFC Used, Second hand

Ref. code: 1.03.307

1100-LFC : Low-Frequency Control Element

The 1100‑LFC low-frequency control element is a self-powered loudspeaker defined by its sonic linearity in reproducing lowfrequency transients at high continuous output levels with very low distortion. This ultra-low distortion, coupled with exceptional headroom and optimized rigging options, makes the 1100‑LFC a flexible tool for low-end directional applications for large-scale tours and installations.
To guarantee optimum performance, design 1100‑LFC systems with Meyer Sound’s MAPP system design tool. This intuitive, cross-platform application accurately predicts directional patterns, frequency and impulse responses, and linear peak SPL for 1100‑LFC systems, ensuring that systems deliver the required coverage and SPL.
An optimally tuned, vented cabinet houses the 1100‑LFC’s two 18-inch, long-excursion cone drivers. The loudspeaker’s 28 Hz to 100 Hz operating frequency range complements LEO, LEOPARD, LYON, JM‑1P, and other Meyer Sound loudspeakers, allowing it to integrate seamlessly with line arrays and curvilinear arrays.
The unit’s power amplifier operates at voltages from 208 to 235 V AC, at 50/60 Hz. TruPower limiting ensures maximum driver protection, minimizing power compression while yielding high constant output under high continuous and peak power conditions. A single, field-replaceable module located on the rear of the cabinet contains the amplifier, control electronics, and power supply.
The 1100-LFC cabinet includes protective plastic skids on the bottom that securely align with the cabinet’s top slots. Units are stackable normally or reversed for cardioid configurations. Meyer Sound tunes and vents the cabinet to specifically optimize it for low air velocities.
The optional MRK‑1100 rigging kit, available as a factory-installed option or field upgrade, includes captive GuideALinks that allow the loudspeaker to be flown from the MTG‑1100 top grid. Convenient pinned handles and slots make the GuideALinks, located at the front and rear of the cabinet, easy to set. The GuideALinks also accommodate reversed units for flown cardioid arrays.
Suspend line arrays comprising up to 16 cabinets at a 5:1 safety factor and BGC V1 from the optional MTG‑1100 top grid. For touring and portable systems, the optional MCF‑1100 caster frame accommodates three-cabinet stacking of the 1100-LFC for secure travel. Optionally available durable nylon covers, accommodating stacks of two or three 1100-LFCs, ensure complete road-readiness.
Meyer Sound’s RMS remote monitoring system comes standard with all 1100‑LFCs and provides comprehensive monitoring of system parameters from a host computer running Compass control software via the RMS interface. Convenient 5-pin XLR connectors allow the use of composite cables carrying both balanced audio and RMS signals (3-pin XLR audio connectors are optionally available).
Meyer Sound constructs the 1100‑LFC cabinet with premium multi‑ply birch and coats it with a slightly textured black finish. A powder-coated, hex‑stamped steel grille with acoustical black mesh protects the unit’s drivers. Other options include weather protection and custom color finishes for fixed installations and applications with specific cosmetic requirements.

Used Meyer Sound Laboratories


Meyer Sound Laboratories is an American company based in Berkeley, California that manufactures self-powered loudspeakers, multichannel audio show control systems, electroacoustic architecture, and audio analysis tools for the professional sound reinforcement, fixed installation, and sound recording industries.
The company’s emphasis on research and measurement has resulted in the issuance of dozens of patents, including for the now-standard trapezoidal loudspeaker cabinet shape. Meyer Sound has pioneered other technologies that have become standard in the audio industry, including: processor-controlled loudspeaker systems, self-powered loudspeakers,curvilinear arraying, cardioid subwoofers, and source independent measurement.
Meyer Sound has consistently involved itself with advanced research beyond that connected to immediate product development, sometimes in conjunction with arms of the University of California, Berkeley. Some of this research has resulted in unusual products such as their parabolic sound beam and sound field synthesis loudspeakers. Other projects, such as the spherical loudspeaker research underway by Meyer Sound and CNMAT (Center for New Music and Audio Technologies) at UC Berkeley are still in the stage of pure research.

Octave: The difference between two frequencies where one is twice the other. For example, 200 Hz is an octave higher than 100 Hz. 400 Hz is one octave higher than 200 Hz.

Optical Digital Cable: Fiber optic cable that transfers digital audio signals as light pulses.

Outcue/Outq/Out-Point: These words all refer to the final few seconds of audio signifying the conclusion of the production.

Package: A completed and fully edited audio piece.

Passive: Not active. A passive crossover uses no external power and results in insertion loss. A passive speaker is one without internal amplification.

Phase: Time relationship between signals it’s all relative.

Power Output: A measure, usually in watts, of how much energy is modulated by a component.

Preamplifier: A control and switching component that may include equalization functions. The preamp comes in the signal chain before the amplifiers.

Pre Outs: Connectors that provide a line-level output of the internal preamp or surround processor.

Pre Outs/Main Ins: Connectors on a receiver that provide an interruptible signal loop between the output of the internal preamp or surround processor portion of the receiver and the input of the amplifier portion of the receiver.

Pre/Pro: A combination preamp and surround processor.

Processors: Anything that processes an incoming signal in some way. Surround processors, for example, can decode a Dolby Digital signal to send to an amp so you can hear it.

Pulse Code Modulation: (PCM) a way to convert sound or analog information to binary information (0s and 1s) by taking samples of the sound and record the resulting number as binary information. Used on all CDs, DVD-Audio, and just about every other digital audio format. It can sometimes be found on DVD-Video.

Q-and-A: Question and answer session.

Receiver: Any component that receives, or tunes, broadcast signals, be it NTSC, HDTV, DBS, or AM/FM radio. Typically refers to the single component that includes a preamp, surround processor, multichannel amplifier, and AM/FM tuner.

Reverberation: The reflections of sound within a closed space.

RF: Radio Frequency. Television signals are modulated onto RF signals and are then demodulated by your television’s tuner. VCRs and DBS receivers often include channel 3 or 4 modulators, allowing the output signal to be tuned by the television on those channels. Also, laser discs used an RF signal for modulating Dolby Digital 5.1 soundtracks on some movies. This requires an RF demodulator (usually referred to as an AC3-RF demodulator) before or in the surround processor to decode the signal.

RMS: Root Mean Square or the square root of the arithmetic mean (average) of the square’s set of values. A reasonably accurate method of describing an amplifier`s power output.

SACD: Super Audio CD. Enhanced audio format with up to six channels of high-resolution audio encoded using DSD. Requires an SACD player. Multichannel also requires a controller with six-channel analog or proprietary digital inputs for full playback.

Sampling Frequency: How often a digital sample is taken of an analog wave. The more samples taken, the more accurate the recording will be. You need to sample at a minimum of twice the highest frequency you want to capture. For example, the 44.1-kilohertz sampling rate of a CD cannot record sounds higher than 22.05 kilohertz.

Scener: A radio report in which the announcer is recorded at the same time and place as the background sound of an event.

Sensitivity: A measurement (in dB) of the sound-pressure level over a specified frequency range created by a speaker driven by 1 watt (2.83V at 8 ohms) of power with a microphone placed 1 meter away.

Signal-to-Noise Ratio: A comparison of the signal level relative to the noise level. Larger numbers are better.

Simultaneous Interpretation: This system allows attendees to hear the meeting in their own language.

Sound Bite: A portion of audio of someone speaking.

Sound field: The total acoustical characteristics of a space, such as ambience number, timing, and relative level of reflections ratio of direct to reflected sound RT-60 time etc.

Soundstage: The area between two speakers that appears to the listener to be occupied by sonic images. Like a real stage, a soundstage should have width, depth, and height.

Speaker: A component that converts electrical energy into acoustical energy.

SPL: Sound-Pressure Level. Measured in dB.

Subwoofer: A speaker designed to reproduce very low bass frequencies, usually those below about 80 Hz.

THX: Certification program for home theater equipment. Uses some proprietary features, but mostly assures a base quality level for a given room size. (See THX select or Ultra.) Is compatible with any and all soundtrack formats. Stands for either Tom Holman’s eXperiment, after the engineer who drafted the original standard, or is named after the company’s founder George Lucas first movie, THX 1138. Nobody agrees on which.

THX select: Certification program for speakers and receivers that assures a base level of quality and performance when played in a room that’s between 2,000 and 3,000 cubic feet.

User-Generated Content (UGC): Text, photos, video or audio supplied by the customers of a company.

Voicer: A radio report without background audio taken from a scene or otherwise.

Wrap: A radio report containing both the reporter and an actuality.
