TOA Corporation, the first manufacturer to bring to the market digital signal processing with the SAORI (1988) and the first digital mixing console, ix9000, has continued this innovation with the introduction of the DP-SP3 audio processor.

TOA Canada Corporation has introduced the SR-D8, an active line array speaker that can project sound waves to targeted areas with greater precision than is possible with conventional speakers.

“By digitally shaping the width and angle of acoustic beams, it can steer sound precisely to desired areas without requiring a change of installation location,” explained Rico Lucia, National Sales Manager for TOA Canada.

“This feature makes it well suited for use in venues where structural or design considerations make it hard to move speakers about or where unwanted reverberation must be kept to a minimum,” he added.

As well as processing both analogue and digital audio input, the SR-D8 speaker harnesses 8 built-in digital amplifiers.

A maximum total of 16 speakers (in up to four stacks) can be managed as a single unit through the GUI-operated software, which provides control of all functions, including mixing, digital signal processing, and simulations.

The intuitive control software enables real-time simulations that—coupled with exceptionally high communication speeds—drastically reduce the time required for designing systems and tuning their acoustic performance. Users can immediately see and hear the results of changing the parameter settings.

In addition, the speaker comes with a wealth of digital signal processing (DSP) functions, including gain, mute , compression, delay, auto-mixing, high/lo w pass filters, high/low shelving filters, and a notch filter.

Equipped with two analogue audio input terminals and four digital audio input terminals for CobraNet connection, the SR-D8 speaker supports 6 x 2 matrix mixing. Using the Auto-mix function, which can be set for each input, enables users to prioritize selected inputs for broadcasting.

Users can also switch from one preset to another, either directly, using the GUI interface, or remotely, using a web browser and the control unit’s Ethernet connection.

Adjusting mixing and DSP parameter settings, running simulations, and communicating—all can be done through the same GUI interface. The software enables quick and easy adjustment of settings, with a simulated graph of the sound pressure distribution providing a visual check of coverage areas according to the settings.

Amplifier modules are constantly monitored for excess temperature and current.
