Apex has introduced the class-D SMA-1 amplifier module, offering a readily customisable turnkey option for two-way active loudspeakers.

Apex SMA-1 amplifier moduleSMA-1 is a purpose-built, fully-featured amplifier module that is easily adapted to customer requirements without the need for a long and expensive custom development process. It combines a switch-mode power supply, two class-D power amplifiers (500W/150W), powerful integrated DSP and all the necessary analogue circuitry optimised for the best sonic performance on a single, extremely compact and lightweight PCBA (Printed circuit Board Assembly) module.

The most basic customer implementation comprises a single Line input, a Link output, a volume knob and status LEDs for signalling Power, Signal and Limit. Customisation is achieved via the input connector on the PCB, which enables the addition of extra input sources such as microphone inputs, Bluetooth, and networked audio, as well as allowing the layout of connectors and controls to be determined, be it a graphic display or LED indicators. Dante audio networking is available as an option, as well as remote control via Apex’s intuitive Intelli-Ware software.

The integrated high-performance DSP enables users to implement custom filter algorithms, creating a specific sound signature without recourse to hardware or any interconnections.

‘We’ve always been good at electronics and we have a long history of providing innovative yet reliable custom solutions,’ says Apex MD, Paul Van Hees. ‘SMA-1 is exactly that – it’s just such a neat solution for manufacturers looking for self-powered amplifier modules. It offers them everything they need, from the most basic to the most sophisticated solution, in a high quality, ultra-compact and extremely affordable format.’
