Sonora, CA – June 2011… Stewart Audio, manufacturer of the finest quality American-made power amplifiers and audio equipment for a wide range of sound reinforcement applications, is pleased to announce the RVC-RS232 RS-232 / Infrared Interface Adapter. This easy-to-use accessory interfaces with any power amplifier equipped with a Remote Volume Control (RVC) Euro block connector—such as Stewart Audio’s own CVA25, CVA50, CVA100-2, and CVA50MX models—to remotely manage volume. This handy interface brings increased accessibility and convenience to a multitude of sound reinforcement environments and enables consultants, system designers, and integrators to easily add a routinely asked for feature to both existing and forthcoming designs.

The Stewart Audio RVC-RS232 interface enables any amplifier with a 5-12VDC RVC connector to be remotely controlled using standard RS-232 commands. The commands available are Increase, Decrease or Mute Volume and include the ability to send discrete values. By adding the optionally available IR plug-in option, the system adds the convenience of infrared remote (IR) control.

The new Stewart Audio RVC-RS232 interface requires no external power supply. Power is provided by the amplifier’s RVC connector—thus eliminating the need for additional power sources and costly labor. Equally notable, this small affordable package enables the RVC-RS232 to reside adjacent to the amplifier or be placed some distance away, thus providing the utmost convenience for installer and end user alike.

Brian McCormick, Chief Marketing Officer for Stewart Audio, commented on the company’s new RVC-RS232 RS-232 / Infrared Interface Adapter. “The Stewart Audio RVC-RS232 interface is a highly compact and versatile accessory that conveniently adds increased functionality in a multitude of sound reinforcement applications,� McCormick notes. “By providing convenient RS-232 or infrared remote volume access to an amplifier, the end user has greater choice in determining how to utilize their sound systems. System designers and integrators can easily add level change functionality to the control options of a Crestron® or AMX® AV control panel and communicate with the power amp via RS-232. Similarly, the optional IR plug-in adapter is a tremendous tool for educators who want fast and convenient level change or mute capability during lectures and other classroom activities. Equally important, the RVC-RS232’s flexible design is ideal for retrofit upgrades of existing amplifiers or new designs. I’m confident this versatile accessory item will find a home in many installed sound environments.�

The new Stewart Audio RS-232 / Infrared Interface Adapter carries the following MSRP pricing:

• RVC-RS232 interface: $99.00
• IR plug-in adapter: $139.00

The Stewart Audio RS-232 / Infrared Interface Adapter is expected to become available July 2011.
