Import Audio Analysers(Atb 701 Qc) — Buy in Bulk from Supplier in China

The ATB 701 QC audio analyser from Leads Engineering Co., Limited is a precision instrument designed for acoustic testing and quality control. It executes a full suite of measurements including Total Harmonic Distortion (THD), Intermodulation Distortion (IMD), frequency response (SPL), impedance (IMP), polarity testing, Thiele-Small parameters, phase analysis, and step response. The system incorporates a dedicated QC program that automates tolerance field settings without script-based programming, streamlining workflows for loudspeaker and audio device manufacturers.

Material and build quality focus on accuracy and repeatability. The analyser uses the M-PN signal for frequency response testing, delivering high-accuracy results with manually or automatically set tolerance masks. For Rub&Buss measurements, it employs signal 13, a dual sine-sweep with a 1:1.3 frequency ratio to expose unit resonances, while the Q-Index calculation isolates noise interference to assess speaker quality. Tests for THD, IMD, and frequencies above K5 verify voice coil placement, glue integrity, and magnet contact, respectively.

This analyser serves manufacturers of loudspeakers, headphones, and microphones, particularly in QC environments where consistent performance is critical. It is suited for production lines requiring rapid, automated pass/fail decisions based on harmonic distortion, wiring polarity, and mechanical defects. Buyers typically confirm compatibility with their existing test setups, as the ATB 701 QC integrates with proprietary or third-party software. Trade terms, including lead times and packaging, are negotiated directly with Leads Engineering Co., Limited in Shenzhen.

Leads Engineering Co., Limited operates from Room 608, Electronic Design Building 4, in Futian District, Shenzhen, Guangdong Province. The company specialises in audio testing equipment, with a focus on precision instruments like the ATB 701 QC analyser. Its profile indicates an imported supplier tier, suggesting it sources or distributes high-end technical products for industrial and QC applications.

The supplier’s trust tier is classified as harbor, reflecting a baseline level of verification. However, its response rate is currently listed as 0.00, with no recorded average response time. This may indicate limited engagement or a need for buyers to proactively reach out for technical clarifications or trade terms. The company’s address and operational focus in Shenzhen align with China’s broader electronics manufacturing ecosystem.
