About this product


The Melodie loudspeaker is a self-powered, three-way design featuring drivers designed and manufactured at Meyer Sound’s Berkeley, California, factory.
The low/low-mid section features two high-power,neodymium-magnet, 8-inch cone drivers with 1.5-inch voice coils, created to meet the power requirements of the system. The drivers are a proprietary design employing neodymium magnets for higher efficiency and power handling with reduced weight.
The lowest frequency range is reproduced by these high-power drivers working in tandem, each powered by a dedicated amplifier channel. To assure the smoothest response in the critical midrange and crossover region, M’elodie incorporates a complex active crossover design.
For low frequencies, both drivers work together, but in the low-mid frequencies only one of the two 8-inch drivers is active. This technique eliminates interference between the drivers that would otherwise occur at shorter wavelengths, while at the same time maintaining optimal polar and frequency response characteristics at the crossover frequency.
The high-frequency section uses a 1.2-inch exit, 3-inch diaphragm compression driver with a neodymium magnet, powered by a dedicated amplifier channel. The output of the driver is coupled to a 100-degree (horizontal coverage) constant-directivity horn through a custom REMmanifold.
The REM is a patented coupling device that introduces driver output to the horn throat across a very short path,effectively controlling the dispersion characteristics, but with dramatically reduced distortion in comparison to other techniques.


Compact High-Power Subwoofer

The 600-HP is a self-powered, high-output subwoofer that may be used in both flown and ground-stacked configurations. It is designed to rig directly with MICA compact, high-power curvilinear array loudspeakers when fitted with the optional QuickFly MRF-600 rigging frame. The versatility of the 600-HP also allows it to be used with a variety of other Meyer Sound self-powered loudspeakers — such as CQ-1, CQ-2, UPA-1P, UPA-2P and UPJ-1P — in fixed and touring applications.
The system features two specially designed high-power 15-inch cone drivers, engineered to provide optimal performance in subwoofer applications. The high-excursion, back-vented drivers have 4-inch voice coils, and each is rated to handle 1200 watts (AES*).
The two cone drivers are housed in a rectangular, optimally tuned and vented enclosure that is the same width as MICA, and a few inches higher and deeper. The enclosure geometry makes vertical ground-stacking easy and convenient. All versions include plastic skids on the bottom of the unit to prevent damage to the enclosure or the unit below the skids align with slots on the cabinet’s top to ensure secure stacking. Operating frequency range is from 36 Hz to 150 Hz, with a peak SPL at one meter of 138 dB.
Each cone driver is driven by a channel of the integral two-channel class AB/H amplifier with complementary MOSFET output stages. Total output power is 2250 watts (4500 watts peak), providing the system with sufficient headroom to accommodate the most extreme sound reinforcement demands with ease. The circuitry includes TruPower limiting to extend the life of the drivers and hold long-term power compression to less than 1 dB. The amplifier, control electronics, and power supply are integrated into a single, field-replaceable module that is mounted into the rear of the enclosure.
The optional MRF-600 rigging frame uses captive, rigid GuideALinks contained within recessed guides in the lower front and rear corners of the enclosure. A slot and convenient pinned handle allow the link to be moved and pinned for arraying or storage. The versatility of angles achieved by using combinations of front and back positions allows a MICA array suspended under 600-HP subwoofers to be uptilted for balcony coverage up to 15 degrees, or downtilted to 6 degrees with respect to the 600-HP. The 600-HP can make use of the optional MG-MICA rigging grid to accommodate a variety of flown and stacked configurations.
The durable enclosure is constructed of premium birch plywood coated with a black, tex- tured hard-shell finish, with a powder-coated, hex-stamped steel grille lined with acoustical black mesh to protect the drivers. The exterior dimensions of the 600-HP are suitable for both European and U.S. trucks, and it can securely travel in stacks using the MCF-MICA caster frame, or MDB-600 dolly board when not fitted with rigging frames.
Options for the 600-HP include weather pro- tection and custom color finishes for fixed installations and other applications requiring specific cosmetics. The RMS remote monitor- ing system — standard with the rigging version and optional with other configurations — allows comprehensive monitoring of system parameters on a Windows-based network.

Manufacturer Description

Active: Powered. An active crossover is electrically powered and divides the line-level signal prior to amplification. An active speaker includes an active crossover and built-in amplifier. Amplifier: A component that increases the gain or level of an audio signal.Balanced Input: A connection with three conductors: two identical signal conductors that are 180 degrees out of phase with each other, and one ground. This type of connection is very resistant to line noise. Bandpass: A two-part filter that cuts both higher and lower frequencies around a center band. A bandpass enclosure cuts high frequencies by acoustic cancellation and low frequencies by natural physical limitations on bass response. Bandwidth: In audio, the range of frequencies a device operates within. In video, the range of frequencies passed from the input to the output. Bandwidth can also refer to the transmission capacity of an electronic communications device or system; the speed of data transfer…very important when planning a meeting for the attendees to stay connected. Bass: Low frequencies; those below approximately 200 Hz. CD: Compact Disc. Ubiquitous digital audio format. Uses 16-bit/44.1-kHz sampling rate PCM digital signal to encode roughly 74 or 80 minutes of two- channel, full-range audio onto a 5-inch disc. Channel: In components and systems, a channel is a separate signal path. A four-channel amplifier has at least four separate inputs and four separate outputs.Crossover: A component that divides an audio signal into two or more ranges by frequency, sending, for example, low frequencies to one output and high frequencies to another. An active crossover is powered and divides the line-level audio signal prior to amplification. A passive crossover uses no external power supply and may be used either at line level or, more commonly, at speaker level to divide the signal after amplification and send the low frequencies to the woofer and the high frequencies to the tweeter. Crossover Frequency: The frequency at which an audio signal is divided. 80 Hz is a typical subwoofer crossover point and is the recommended crossover point in theatrical and home THX systems. Frequencies below 80 Hz are sent to the subwoofer; signals above 80 Hz are sent to the main speakers.Decibel (dB): A logarithmic measurement unit that describes a sound's relative loudness, though it can also be used to describe the relative difference between two power levels. A decibel is one tenth of a Bel. In sound, decibels generally measure a scale from 0 (the threshold of hearing) to 120-140 dB (the threshold of pain). A 3dB difference equates to a doubling of power. A 10dB difference is required to double the subjective volume. A 1dB difference over a broad frequency range is noticeable to most people, while a 0.2dB difference can affect the subjective impression of a sound.Delay: The time difference between a sonic event and its perception at the listening position (sound traveling through space is delayed according to the distance it travels). People perceive spaciousness by the delay between the arrival of direct and reflected sound (larger spaces cause longer delays).Diaphragm: The part of a dynamic loudspeaker attached to the voice coil that produces sound. It usually has the shape of a cone or dome.Diffusion: In audio, the scattering of sound waves, reducing the sense of localization. In video, the scattering of light waves, reducing hot spotting, as in a diffusion screen.Digital Audio Server: Essentially a hard drive, a digital audio server stores compressed audio files (like MP3 or WMA). Most include the processing to make the files, and all have the ability to play them back.Dispersion: The spread of sound over a wide area.Distortion: Any undesired change in an audio signal between input and the output.Dolby B: A noise-reduction system that increases the level of high frequencies during recording and decreases them during playback.Dolby C: An improvement on Dolby B that provides about twice as much noise reduction.Dolby Digital: An encoding system that digitally compresses up to 5.1 discrete channels of audio (left front, center, right front, left surround, right surround, and LFE) into a single bitstream, which can be recorded onto a DVD, HDTV broadcast, or other form of digital media. When RF-modulated, it was included on some laser discs, which requires an RF-demodulator before the signal can be decoded. Five channels are full-range; the .1 channel is a band-limited LFE track. A Dolby Digital processor (found in most new receivers, preamps, and some DVD players) can decode this signal back into the 5.1 separate channels. Most films since 1992's Batman Returns have been recorded in a 5.1 digital format, though a number of films before that had 6-channel analog tracks that have been remastered into 5.1.Dolby EX: An enhancement to Dolby Digital that adds a surround back channel to 5.1 soundtracks. The sixth channel is matrixed from the left and right surround channels. Often referred to as 6.1. Sometimes referred to as 7.1 if the system uses two surround back speakers, even though both speakers reproduce the same signal. Software is backwards-compatible with 5.1 systems, but requires an EX or 6.1 processor to obtain additional benefit.Dolby Pro Logic: An enhancement of the Dolby Surround decoding process. Pro Logic decoders derive left, center, right, and a mono surround channel from two-channel Dolby Surround encoded material via matrix techniques. Dolby Pro Logic II: An enhanced version of Pro Logic. Adds improved decoding for two-channel, non-encoded soundtracks and music. Driver: A speaker without an enclosure; also refers to the active element of a speaker system that creates compressions and rarefactions in the air.DSP: Digital Signal Processing. Manipulating an audio signal digitally to create various possible effects at the output. Often refers to artificially generated surround effects derived from and applied to two-channel sources.DTS: Digital Theater Systems. A digital sound recording format, originally developed for theatrical film soundtracks, starting with Jurassic Park. Records 5.1 discrete channels of audio onto a handful of laser discs, CDs, and DVDs. Requires a player with DTS output connected to a DTS processor.DTS ES: An enhanced version of the 5.1 DTS system. Like Dolby's Surround EX, a sixth channel is added. In some cases (DTS ES Discrete), the sixth channel is discrete. Software is backwards-compatible with 5.1 systems, but requires an ES or 6.1 processor to obtain additional benefit. Neo: 6 is a subset of DTS ES that creates 6.1 from material with fewer original channels.Dynamic Range: The difference between the lowest and the highest levels; in audio, it's often expressed in decibels. In video, it's listed as the contrast ratio.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. 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 amicrophone 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.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.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.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.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.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.surround processor portion of the receiver and the input of the amplifier portion of the receiver.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.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. 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 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. 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.
