- Rio Casino First Installation for Meyer HM-1 Loudspeakers
The Meyer Sound File - Spring 1997
The Rio Suite Hotel & Casino in Las Vegas, Nevada, is the first venue to feature Meyer Sound HM-1 Remote-Monitored Loudspeakers, the newest addition to the Meyer Sound family of self-powered loudspeakers. One hundred thirty HM-1s were recently installed in the casino's new "Masquerade Show in the Sky," a system of moving floats that glides above the casino floor, carrying casino guests and costumed performers. The new loudspeakers are installed in walls along the float route and carry music for the flotilla's Carnivale theme. "Masquerade Show in the Sky" is part of the casino's new $200 million venue, Masquerade Village, a casino celebrating Carnivale festivals around the world. Masquerade Village opened to the public on February 7.
Sound designer Jonathan Deans of Real Time Audio selected the HM-1 for its sound quality and ease of installation. "The HM-1 has no competition," he says. "It's the only self-powered loudspeaker with superior sound quality and the ability to run at 48 volts. The SPL and sound quality are surprising for its size."
The HM-1 is a compact, two-way system comprising a seven-inch graphite cone low frequency driver and a concentrically-mounted one-inch soft-dome high frequency driver with a constant-directivity horn. Both drivers, along with biamplifiers, an active crossover, and circuitry for driver protection and frequency and phase response, are packaged in a magnetically shielded, vented wood enclosure measuring 8.5 inches by 11 inches by 9.5 inches. The complete loudspeaker weighs only 12 lbs. and accepts a simple, unipolar 48 volt DC power source. The speaker's balanced signal input may be supplied using twisted pair wiring. The HM-1 provides flat frequency response from 40 Hz to 20 kHz (at -6 dB points) with symmetrical 100░ coverage in both the horizontal and vertical axes, and a maximum output of 116 dB SPL.
The HM-1 is available with two auxiliary products: a remote power supply that accepts AC main inputs from 80 to 280 volts at 50/60 Hz and powers two HM-1s, and a subwoofer with a ten-inch cone driver that increases the system response at 40 Hz by 6 dB and is powered directly from the HM-1's low frequency amplifier output.
"We knew we could save contractors time and money by developing a high-power loudspeaker that meets the 48 volt building code limit," says John Meyer, president of Meyer Sound. "By eliminating the need for conduits in installations, the HM-1 succeeds in offer a versatile, cost-effective solution with the superior sound quality people expect from Meyer Sound."
Meyer Sound first demonstrated the HM-1 at the NSCA show in Charlotte, North Carolina, April 16-20.
