SA-400 Multi-channel Amplifier

The commercial-grade SA series multi-channel professional amplifiers are built for background music and public broadcasting across malls, hotels, schools, factories and offices, with standardized design, stable output and flexible expansion — one amplifier for multi-zone sound. The SA-400 is the 4-channel version.

Key Features

Multi-channel Zone Control: 50W independent output per channel drives speakers in different zones with independent control — synchronous or zoned playback from one unit.

Standard 4Ω Impedance: Directly matches mainstream fixed-resistance PA and full-range speakers with no additional adjustment required.

Clear & Natural Sound: Complete 20Hz–20kHz response, 80dB S/N and 1% low distortion keep background music and announcements clean, comfortable listening all day.

Engineering-grade Chassis: Uniform 420×96×290mm size fits standard racks; complete built-in protection circuits support 7×24 commercial operation.

Right-sized Value: 2/4/6-channel models cover everything from small shops to large campuses — pay only for the zones you need.
