“Switching to Xinchangda’s crossover power amplifier cut our energy bill by 28 % and eliminated the 6‑month downtime we used to experience with previous vendors.” – John M., Operations Manager, SoundTech USA
“The OEM design team delivered a custom 3‑band network in 10 days, allowing us to meet a tight product launch schedule.” – Linda K., Technical Director, MedImaging Corp.
What is the typical lead‑time for a custom crossover power amplifier order to the USA?
Standard OEM units ship within 7‑10 business days. For custom OEM/ODM designs, our 10 R&D engineers can deliver a prototype in 14 days and full‑scale production in 2 weeks after design approval.
Can the amplifier be integrated with existing audio‑DSP systems?
Yes. We provide configurable input/output impedance and optional RS‑485 or Ethernet control modules that sync with most DSP platforms (e.g., Biamp, QSC, Crestron).
What certifications are required for importing into the United States?
Our units are FCC Part 15 certified and come with a Declaration of Conformity, satisfying U.S. customs and safety regulations. We also provide CE and RoHS documentation for global shipments.
Do you offer sample units before full purchase?
A 30‑day free‑sample program is available for qualified corporate buyers. Shipping to U.S. mainland is covered; you only pay customs duties if applicable.
What after‑sales support do you provide?
We offer 24 / 7 technical hotline, on‑site training (optional), and a 2‑year warranty covering parts and labor. Firmware updates are released quarterly.
