The demand for exceptional audio quality is no longer limited to theatres and concert halls. In truth, with the Meyer Sound IntelligentDC technology to make the sonic and logistical advantages of self-powered systems more accessible, there is no reason to compromise on quality. With the IntelligentDC power supply driving power and balanced audio using a multi-conductor cable, remotely powered Meyer Sound installation loudspeakers make it much easier to provide exceptional audio everywhere, including hotel lobbies, cinemas, airports, corporate offices, and museums.
At InfoComm 2014 in Las Vegas, visit the Meyer Sound demo room to hear loudspeakers with IntelligentDC technology in person, and experience how they share the same sonic excellence that defines their AC counterparts. You can schedule a loudspeaker demo at InfoComm by emailing the Meyer Sound sales team here.
In the mean time, to find out whether these products are right for your next commercial audio project or art installation, the information below answers some of the most common questions from integrators and consultants about these products.
Q: What are Meyer Sound IntelligentDC solutions?
Meyer Sound loudspeakers with IntelligentDC technology share the same core technologies as the company’s self-powered AC systems. The significant difference is that the power supplies in IntelligentDC systems are not housed inside the loudspeakers, but in the form of a rack-mount IntelligentDC power supply that feeds eight loudspeakers each. One cable carries both power and balanced audio to simplify the installation process.

Q: What are the ideal applications for loudspeakers with IntelligentDC?
These loudspeakers are ideally suited for providing Meyer Sound’s self-powered advantage and legendary audio quality in installations where local AC outlets are not available and running conduit is not desired or not possible. This includes many retrofit projects and distributed sound applications.
IntelligentDC technology is often the most cost-effective solution for high quality sound when the user needs to address each loudspeaker individually or in small groups, allowing optimum control of EQ, delay, and level. Typical applications include high-end retail, restaurants and bars, hotel lobbies, airports, corporate offices and meeting rooms, museums, and auxiliary systems in performing arts centres.
Q: How does IntelligentDC technology simplify the installation process?
In distributed sound applications, the sonic advantages of self-powering are retained with no need for AC outlets at each loudspeaker location. In many countries, conduit is not required: the wiring is classified as Class 2 in North America or Protective Extra Low Voltage (PELV) in Europe. No transformer wiring and tap setting is required as with 70/100V systems, and no heavy loudspeaker cables are required as with low-impedance systems.
Q: What type of cable is used?
Connection of loudspeakers requires three conductors for balanced audio plus two conductors for DC powering. Although separate audio and power cables can be used, in most cases it is easier to use a single 5-conductor (e.g. Belden 1502) which is similar in weight to a Cat-5 cable.
Q: What connectors are available?
Most models can be ordered with either a Phoenix 5-pin or an EN-3 5-pin connector, though a few offer only one or the other. Loudspeaker models suited to outdoor applications in theme parks, themed spectaculars and open-air hospitality installations also offer the robust and environmentally sealed and locking ECO-M 7-pin connector.
Q: What are the advantages of IntelligentDC compared to non-powered constant voltage distributed systems?
Sonic performance is vastly improved. The systems have very low distortion, greatly enhancing the listening experience and minimizing fatigue. Transformers are eliminated, and all the advantages of Meyer Sound self-powered systems are realized: flat phase and frequency response and true bi-amplified operation in two-way systems. Also, loudspeakers may be quickly rezoned in the equipment room without any rewiring in the ceiling.
Q: What are the advantages compared to low-impedance loudspeaker systems?
Long loudspeaker cable runs are eliminated, along with the attendant costs for heavy-gauge cable and the sonic degradation from cable impedance.
Q: What are the advantages compared to conventional loudspeakers?
Amplifier racks are eliminated, saving valuable floor space and reducing cooling costs.
Q: Is there a performance difference between the standard AC Meyer Sound loudspeakers and the IntelligentDC option?
The IntelligentDC version shares the sonic quality and power specifications with the AC version.
Q: How many loudspeaker models are available with IntelligentDC?
Meyer Sound currently offers 12 loudspeakers with IntelligentDC. The smallest in the installation line, the MM-4XP, has a four-inch square faceplate, measures less than six inches deep, and weighs 4.2 lbs. The UPJ-1XP is the most powerful, with a peak output of 128 dB SPL across an operating frequency range of 55 Hz to 20 kHz. The line also includes both the UMS-1XP and MM-10XP subwoofers.
Q: How does the IntelligentDC power supply operate?
MPS-488HP, the Meyer Sound IntelligentDC power supply, sends power and signal to up to eight loudspeakers at cable lengths up to 150 feet or 300 feet (depending on the loudspeaker model) with just 1 dB of loss in peak SPL using 18 AWG wire. Its outputs are equipped with sophisticated microprocessor-controlled current limiting that protects each channel from short circuits and unexpected voltages. LEDs on the MPS-488HP front panel provide useful feedback on the status of the system. In addition, the power supply automatically selects the correct operating voltage, allowing international use without manually setting voltage switches.
Q: Do IntelligentDC systems offer remote amplifier/loudspeaker monitoring?
Yes, by using the MPS-488HP external power supply. IntelligentDC technology eliminates the need for a separate cable to connect a loudspeaker to the Compass RMS remote monitoring system, the Meyer Sound tool for comprehensive monitoring of critical loudspeaker and amplifier parameters as well as individual loudspeaker muting.
Q: What benefits does IntelligentDC technology offer to surround applications?
IntelligentDC technology has been widely adopted in a range of surround applications, including film post-production and exhibition particularly in conjunction with new immersive formats like Dolby Atmos and Auro-3D. Because each surround speaker carries a discrete channel, IntelligentDC technology is the only practical solution for providing the power and clarity of self-powered, bi-amplified systems at a cost comparable to conventional low-impedance systems.
