Opu's high-precision audio analysis

AD2504 Audio Analyzer | Ideal choice for multi-channel production line testing
——High performance expansion scheme based on AD2000 series

AD2504 is a basic audio analyzer launched by Opxin to meet the testing needs of multi-channel production lines. It inherits the high-precision testing gene of AD2502 and extends to2 in 2 out analog interfaceSupports synchronous collection and signal generation, significantly improving the efficiency of production line testing. its230Vpk maximum input voltageand90kHz bandwidthCovering high-frequency and high-voltage scenarios, coupled with optional digital module expansion, it has become a versatile testing tool in fields such as consumer electronics and automotive electronics.

Core strengths

1. Multi channel parallel testing increases production line efficiency by 50%

• Supports dual channel analog input/output, synchronously completes left and right channel, multi device comparison testing, and shortens the testing cycle.

• Compatible with automated testing scripts, seamlessly integrated with MES systems on production lines, achieving unmanned testing.

2. High voltage and high bandwidth, covering all types of audio devices

• 230Vpk input voltageEasily handle high voltage equipment testing such as professional speakers and car amplifiers.

• 90kHz bandwidthAccurately capture high-frequency details and adapt to broadband devices such as headphones and Bluetooth LE Audio.

3. Modular expansion, one machine for multiple purposes

• Standard dual channel analog interfaceOptional digital modules such as DSIO, PDM, HDMI, BT DUO, etc.

• Support USB/SPDIF digital audio analysis, covering all scenario requirements from research and development to production line.

4. Combining high precision and stability

• Inheriting the AD2000 series0.01% accuracyGene, THD+N is as low as -110dB to ensure testing reliability.

• Industrial grade design, suitable for complex environments such as high temperature and electromagnetic interference on production lines.
