Optimal Audio Smart Amp 10

SmartAmp 10 is an amplifier with built in Digital Signal Processing (DSP) specifically tailored to optimise the performance of the Optimal Audio loudspeaker range.

This two-channel 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 space efficient half-width, 1U, 19” rack housing enables two units to be mounted side by side with another SmartAmp 10 or SmartAmp 20 allowing up to 6 channels in a 1U space.

The SmartAmp 10 is capable of a maximum of 250W output shared between the two channels. This enables SmartAmp 10 to flexibly deliver power required for each channel depending on the system requirement. For example, if channel one was to only be using 20W of power for some Up speakers, channel two could deliver the remaining 230W of power for a more demanding application.

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.
