Amp Box S3 CI

Audiophile micro stereo power amplifier for custom installation

Custom Integration amp with Amp Box S3 technology inside!

The new Amp Box S3 CI enhances our Amp Box S3 design with new custom integration features.

Auto Power: powers on the unit automatically as soon as power supply is connected
Signal Sensing: monitors the input and turns the unit on/off depending on whether there is an input signal or not
RS232: control protocol widely used in custom integration, allows automation and smart home or home theater integration
Level / Bass / Treble controls: a must to fine tune level and frequency response to match any system
Professional grade connectors: safe and secure, no accidental unplugging of cables

The new Amp Box S3 CI offers custom integrators the perfect tool for powerful and room-filling sound to every loudspeaker. The same new PCB concept & sophisticated topology as in our Amp Box S3 achieves less distortion and a better signal to noise ratio. We designed this amp to match the sound characteristics of a tube amplifier as close as possible.

Application examples:

  • HiFi amplifier with EQ for 10-15 m2 rooms
  • Perfect amp addition for modern streamers
  • Studio desktop amp for nearfield monitors
  • Multiroom power amp solution
  • Home cinema power amp upgrade
  • In-wall or celing speaker amp
  • Smart Home integration using RS232
  • Lobbies & Hotels with complex RS232 integration
  • Restaurants and Cafés audiophile PA system

Amp Box S3 CI comes in a full aluminium housing, which effectively protects against interferences and vibrations! A must, considering the complex use cases where interference and EMI/RFI radiation will be high! With its small size, the Amp Box S3 CI will not take up the very limited space that custom integrators often struggle with. When the Amp Box S3 CI is not hidden and proudly displayed in studio or home theater systems, the simple and luxurious design with beautifully finished aluminium surfaces allows for a clean and beautiful setup.

The new Amp Box S3 CI is designed and produced in Europe and is available in a black & silver finish.
