Rich, powerful sound with large display solutions

Give every audience member a rich, powerful sound experience in corporate and educational environments. The SLS-1A is a compact, uniquely versatile line-array speaker system that offers an ideal audio reinforcement solution in conjunction with large display solutions including our BRAVIA professional displays, projectors, and Crystal LED video walls.

Clear, low-distortion full-range sound

The SLS-1A features eight full-range driver units mounted in a line array configuration, supplemented by a powerful integrated multi-channel amplification system. Sound is delivered with remarkable richness, accuracy and presence in any listening environment.

Flat and square diaphragm

Provides ideal point source with reduced inter-modulation distortion.

Magnetic fluid speaker

Original Sony technology eliminates voice coil damper found in standard speakers, reducing distortion for clearer sound.

Integrated amplification

8x10W amplifier plus integrated 8-channel 96kHz DSP ensures pure, clear audio, with separate bass reflex driver for extended low frequencies.

Compact size, flexible installation

The SLS-1A offers an ideal sound solution in a wide range of listening environments. The compact line-array unit can be discreetly mounted to suit any size or shape of room. Multiple SLS-A1 units can be mounted horizontally or vertically, and ‘cascaded’ via a single Ethernet cable as part of a Dante® digital audio network to simplify wiring in large-scale AV installations.

Compact yet powerful

Rigid aluminium body measuring just 92 x 384 x 110*mm houses speakers and amplification, delivering high sound pressure levels from a compact unit.

*100mm without speaker grille

Flexible mounting and expansion options

Mount horizontally or vertically. Easily link multiple units for larger scale sound installations.

Flexible beam setting

Adjust sound settings using hardware switches, third party EASE® Focus software or Sony’s PC app that controls beam steering, spread and EQ.

On-screen centre sound localisation

The SLS-1A is an ideal sound reinforcement partner for large display installations including our BRAVIA 100” 4K professional display, projectors and Sony’s Crystal LED system. In contrast with normal point-source speakers, the SLS-1A offers a large ‘sweet spot’ that can be accurately controlled for clear, consistent sound over a wide listening area in any venue – from corporate showrooms, entrance lobbies and retail spaces to lecture theatres and auditoriums. The finely controlled beam is also particularly suited to providing even sound coverage in venues like auditoriums with a raked floor.

Better sound in any room

Unlike standard speakers, the line array design of the SLS-1A minimises sound reflections from ceilings, walls, and floors. Audiences can hear uniform, clearly directed sound with less attenuation over long distances, independent of room size or shape.
