Springfield, MO (May 5, 2005)--SLS Loudspeakers has introduced the newest addition to its Studio Reference Series, the PS8R. Incorporating the new Evenstar Sigma-Delta digital amplifier technology, the PS8R offers studios the S8R ribbon-equipped reference monitor as a standalone, biamplified, nearfield, critical-listening monitor system.

"Our engineering staff at SLS Evenstar has incorporated their experience with fixed-carrier digital amplifiers and modern digital converter technologies to produce the amplifier section of the PS8R," says Jeff Lowry, director of marketing for SLS. "The utilization of this advanced amplifier technology combined with the highly desirable sound of the original S8R, has produced a real advancement in nearfield monitor technology and sound accuracy. We believe that the PS8R will have a significant impact on the industry."

The Evenstar Sigma-Delta digital amplifier in the PS8R has been customized and matched to power the S8R drivers with headroom, damping and uniform response. The unique amplifier topology lowers distortion (both harmonic and inter-modulated), increases bandwidth and improves noise performance over traditional amplifier technologies. The amplifier maintains high efficiency as well as being compact, lightweight and low heat producing.

Two robust power supplies were incorporated to minimize crosstalk and deliver clean power-supply rails for both high- and low-frequency amplifiers. Additionally, a balanced receiver and a 2-channel active crossover was custom designed and matched to the S8R acoustic performance to allow maximally flat response and accurate time alignment, yielding a frequency response of 44-20,000 Hz (+/-2 db). The low-frequency amplifier delivers 180Wrms of output power to the 8-inch woofer with an integral phase plug, while the high-frequency amplifier yields 40Wrms to drive the PRD500 5-inch ribbon driver. Maximum SPL is 110 dB @ 1m.
