4 x 250W amplifier with integral DSP
SmartAmp 30 is a 4-channel Class D power amplifier with onboard DSP, designed to work with Optimal Audio loudspeakers. Rear-panel dip-switch presets cover a wide range of Optimal Audio speakers — an installer selects the preset for the speaker being driven and the system is correctly configured: EQ shaped, limiting set, headroom protected. No external processor required, no manual tuning. For installations requiring custom speaker profiles or third-party loudspeaker support, the Custom Configurator extends this further.
SmartAmp 30 can drive both conventional low-impedance and 70V/100V constant voltage loudspeaker loads. DSP presets are selected by switches on the rear panel, enabling the appropriate EQ and overload protection for each speaker.
SmartAmp 30 is the highest-output model in the SmartAmp range, delivering a consistent 250W per channel into 4Ω–16Ω — there is no power sharing between channels, so each channel delivers its full rated output independently. The full-width 1U housing fits a standard 19″ rack. SmartAmp 30 is well suited to installations requiring more output per channel than SmartAmp 10 or 20 can provide.
Power Factor Correction power supply technology enables universal AC mains operation without the need for local market power regulation. Ultra-low standby power consumption meets EuP2103 and Energy Star compliance.
For standalone installations, SmartAmp 30 pairs with a ZonePad VL1 for simple in-room volume control without a Zone controller. For larger installations requiring multi-zone scheduling and WebApp control, SmartAmp 30 works alongside any Optimal Audio Zone controller .
