Page 15: Chapter 1: 880 Series Mounting Frames
Chapter 1 880 Series Mounting Frames Overview The 880 series, 8-output audio distribution amplifiers meet the most demanding requirements for AM/FM/TV broadcast and program production systems. Heading the list of the amplifier’s exceptional performance characteristics is the 100 dB S/N ratio. Flat frequency response, carefully controlled roll-off and very low distortion ensure a virtually transparent transmission path. -
