SR-D8 Active Line Array Speaker


The TOA SR-D8-S is an all-in-one active line-array speaker that features CobraNet protocol digital audio input, digital signal processor, digital power amplifier and speakers configured in a line array. Precise control of the speaker's vertical directivity and acoustic beamwidth makes it possible to create fully optimized sound spaces in a wide range of locations. All function settings can be controlled from a remote PC using the supplied setting software. Equipped with primary audio input, the SR-D8-M (option) transmits the audio signal to the secondary SR-D8-S via the SR-D8-M's dedicated local link. The local link allows up to 3 SR-D8-S speaker units to be connected in series to one SR-D8-M (option), permitting a line array of up to 4 connected speakers (hereinafter, this multi-unit array is referred to as "stack") to be configured. In a complete system, up to 4 stacks can be controlled, making it possible to build speaker systems consisting of up to 16 speakers.
