Model 190 

With Code 810 (Premium sound system) except code 811 (High-End sound system) 

Shown on model 190.3 up to 30.11.2018 

N40/3 Sound system amplifier control unit 

Location 

The sound system amplifier control unit is located in the trunk on the right sidewall.

Tasks 

The sound system amplifier control unit receives electrical signals, amplifies and optimizes them, and then sends the processed signals for output to the speaker system.

The sound system amplifier control unit receives the following signals:

• Voltage supply
• Visual and electrical wake-up signal
• Muting of audio sources (mute function), of:
  • Emergency call system control unit (N123/4) (with CODE 348 (Emergency call/assist system))
  • Telematics services communications module (N112/1) (with code 06U (Mercedes connect me basic services) or code 350 (eCall Europe emergency call system))
  • HERMES control unit (N112/9) (with code 360 (HERMES UMTS) or code 362 (HERMES LTE))
• Control and audio signals over the Media Oriented System Transport (MOST) from the head unit (A26/17)
• Audio signals via MOST from the tuner unit (A90/4) (with code 536 (SIRIUS satellite radio) or with code 537 (Digital radio (DAB)) up to 30.11.2018)
• Audio signals via MOST from the TV tuner (N143) (with code 865 (TV tuner) as of 01.12.2018)

The sound system amplifier control unit optimizes and amplifies the signals or it evaluates them:

• Optimization of input signals through digital signal processing and sound optimization algorithms (e.g. surround sound)
• Support of stereo and multichannel entertainment channels as well as announcement channels (e.g. for voice output in voice control system (with CODE 531 (COMAND APS)) or navigation instructions)
• Amplifying of the input signals and assignment of the output to the speakers
• With code 598 (Gasoline particulate filter (OPF) with sensor system): Optimization of engine and exhaust system sound in the vehicle interior through generation of simulated sound contributions through the speaker system

The sound system amplifier control unit sends the processed signals to the following components:

• Left front footwell woofer (H4/9)
• Right front footwell woofer (H4/10)
• Center instrument panel midrange speaker (H4/27)
• Rear woofer (H4/29)
• Left instrument panel tweeter (H4/33)
• Right instrument panel tweeter (H4/34)
• Left rear midrange speaker for surround sound system (H4/62)
• With code 598 (Gasoline particulate filter (OPF) with sensor system): Control signals for optimization of engine and exhaust system sound in the vehicle interior, over the CAN interface from the drive CAN (CAN C1), e.g. engine speed and engine load from the ME-SFI [ME] control unit (N3/10)
• Right rear midrange speaker for surround sound system (H4/63)
• Left door midrange speaker (H4/86)
• Right door midrange speaker (H4/87)
