NanoPlayer Box Specifications and Pinout: Technical Guide

This guide summarizes all the technical data and connector pinouts to help you configure your NanoPlayer Box independently.

Electrical Specifications and Power Supply

The choice of power supply is critical, as it defines the available power for your speakers.

• Power supply voltage: 12V DC nominal.
• Tolerance range: 10V to 15V DC (warning: any exceedance may damage the player).
• Power connector: Standard DC jack with an outer diameter of 5.5 mm and an inner diameter of 2.1 mm.
• Typical consumption (at 12V):
  • Line output only: approximately 70 mA to 100 mA.
  • Playback with amplifier at maximum (8 Ω load): up to 2A.
• Recommendation: For full use (maximum amplification and accessories), provide a power supply delivering at least 3.45 A. Insufficient power with speakers will cause sound distortion and power adapter overheating.

Audio Amplifier Specifications

The player integrates a high-performance dual Class D amplifier.

• Volume control: Digital control with 32 steps, simultaneously affecting all outputs (line, speakers, headphones).

Connector Pinout
