T/SDWY 001-2022 The aging technology specification for audio power amplifier
Basic Information
Scope
Scope: 1. Scope This document specifies the requirements for the production process and design change/aging control of audio power amplifiers. This document applies to the entire production process and design change/aging of audio power amplifiers. Main Technical Content: 4. Documents and Personnel 4.1 Documents 4.1.1 The production enterprise shall formulate product aging safety operating procedures and work instructions. 4.1.2 The production enterprise's product aging documents or specifications shall meet or exceed the technical requirements of this document. 4.1.3 The production enterprise shall ensure that the original records of product aging are clear, complete, and traceable, serving as the basis for verifying the product's compliance with regulatory requirements. 4.1.4 The original records of product aging shall be preserved for at least 2 years. 4.2 Personnel Operators shall undergo relevant training in aging safety operations and quality management fundamentals and work with valid certifications. 5. Power Requirements The product shall operate at the nominal voltage specified by the production enterprise. During product aging, the power voltage shall be maintained stable, with deviations no greater than ±4.4V. 6. Aging Connections 6.1 The audio power amplifier used for aging shall be a pink noise signal. 6.2 A control/regulator capable of adjusting signal magnitude shall be connected between the audio source generator and the audio power amplifier to adjust the output amplitude of the audio power amplifier. 6.3 Audio power amplifier settings: Set the input signal to the product's minimum electromotive force, and set the equalizer to a flat position. 6.4 Connect a load (resistance) to the audio power amplifier output. 6.5 Monitor the output voltage using a calibrated true RMS meter between the audio power amplifier and the load. 6.6 See Figure 1 for the aging connection diagram. 7.
