SmartAmp 30
4 x 250W amplifier with integral DSP
Features
- Desktop or rack mounted
- Signal processing presets for Optimal Audio loudspeakers
- 250 watts per channel into 4Ω-16Ω and 70V-100V line loudspeaker loads
- Universal Mains, PFC and Energy Star Compliant
SmartAmp 30 is an amplifier with built in Digital Signal Processing (DSP) specifically tailored to optimise the performance of the Optimal Audio loudspeaker range.
This four-channel 1U, 19”, power amplifier can drive both conventional low impedance and 70V – 100V loudspeaker loads. Internal DSP presets of Optimal Audio loudspeakers are selected by switches to the rear of the amplifier, which enable the appropriate EQ and overload protection settings.
The SmartAmp 30 can be configured to drive either low or high impedance loads at a maximum of 250W per channel, giving the options of a localised or evenly distributed speaker system.
The SmartAmp 30 is ideally suited to power multiple speakers and models from Optimal Audio.
Power factor Correction power supply technology enables universal AC mains operation, eliminating the need for local market specific power regulation and potential reliability issues. The power supply delivers consistent, regulated power worldwide with ultra low standby power consumption for EuP2103 and energy star compliance.
