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.

Optimal Audio SmartAmp 10 Amplifier FAQs
The SmartAmp 10 combines power, versatility, and user-friendliness, making it a good choice for various commercial audio applications. Here are some key benefits:
- Power and Flexibility: Offers 2 channels with 125 watts per channel (at 4Ω-16Ω impedance) and the ability to share power dynamically between channels. This allows you to efficiently drive demanding speakers or allocate more power to specific channels as needed.
- Built-in DSP with Optimal Audio speaker presets: Simplifies setup for Optimal Audio speakers by using pre-configured DSP settings for optimal performance.
- User-friendly Operation: Designed for straightforward operation with features like sleep mode for energy saving and clear level indicators.
- Compact Design (half-width 1U): Enables space-efficient rack mounting, allowing for two units in a single 1U rack space alongside other SmartAmp models for multi-channel systems.
The SmartAmp 10’s versatility makes it suitable for various background music and public address applications in commercial settings, such as:
- Retail stores: Background music to enhance the shopping experience.
- Offices: Background music and announcements in common areas, conference rooms, or break rooms.
- Hotels and hospitality: Background music and announcements in lobbies, hallways, or common areas.
- Restaurants and bars (with background music needs): The SmartAmp 10 is suitable for areas with moderate ambient noise where clear audio is important.
- Smaller venues: Powering speakers in conference centres, classrooms, or event spaces.
The SmartAmp 10 is a versatile amplifier designed to power a wide range of Optimal Audio speakers, including:
- Ceiling speakers: Up 3, Up 4, Up 6 (multiple speakers possible depending on impedance)
- On-wall speakers: Cuboid 3, Cuboid 5, Cuboid 6, and Cuboid 8 (depending on speaker impedance and total power requirements)
- Subwoofers: Can be used to power the Sub 10 subwoofer. While not explicitly stated, it might also be suitable for other passive subwoofers with compatible impedance ratings.
