Professional Sound Reinforcement – A touring sound company ordered 12,000 units for line‑array systems; on‑time delivery avoided a $75k penalty.
“Xinchangda’s transformers cut our component cost by 22% and the 7‑day lead time kept our launch schedule intact.” – James L., Procurement Manager, SoundWave Labs
“Zero‑failure rate over 18 months of field operation. The CE and FCC certifications saved us from customs holds.” – Maria K., Technical Director, MedTech Instruments
Our factories hold CE, FCC, RoHS, CB, VDE, ISO 9001, and GS certifications, ensuring compliance with U.S. and EU regulations.
What is the typical MOQ for custom audio output transformers?
Our standard MOQ is 1,000 pieces. For orders between 1,000‑5,000 units we can use the “Express Production” line with a 7‑day turnaround. Larger volumes receive a 5% price break.
Can you provide CE and FCC certification for each batch?
Yes. Every production batch is tested against CE (EN 61000‑4‑3) and FCC Part 15 standards. Test reports are attached to the shipping documents.
Do you support OEM branding and packaging?
Absolutely. We offer white‑label, custom silk‑screen printing, and pre‑filled packaging per your brand guidelines at no extra tooling cost for orders over 5,000 pcs.
What are the payment terms for first‑time U.S. buyers?
We accept T/T (30 % deposit, 70 % before shipment) or L/C at sight. For qualified accounts we can extend to 30‑day Net after the first successful order.
How is after‑sales service handled?
Our U.S. technical support team is available 24 × 5 via email and WhatsApp. We provide a 12‑month warranty, free replacement for any DOA units, and a dedicated account manager for large accounts.
