Is the Frequency Adjustable?

For FM transmitters below 2KW, frequency is adjustable. For TV transmitters, the band is narrow and not adjustable.

Can your Analog TV Transmitter be upgraded to Digital?

Yes, if the frequency band is the same. However, power reduces by 5 times (e.g., 1KW analog becomes 200W digital).

How to do installation of these equipments?

Small power stations are easy to install. For large stations, we can send an engineer to help (cost paid by buyer) or train your engineers at our company.

How to operate these broadcasting equipments?

We provide an All-English user manual and operation software. We also offer training for your engineers at our company.

What is the after-sales service and warranty?

Warranty is one year after leaving the factory. We provide technical support via internet or in-person and send spare parts for damaged equipment.

AI-Powered supplier vetting

SummaryZHC, legally identified as Hangzhou Zhongchuan Digital Equipment Co., Ltd., is a China-based manufacturer/factory in Hangzhou, Zhejiang, specializing in FM and TV wireless broadcasting equipment. Its stated capabilities cover R&D, production, marketing, engineering installation, and after-sales service. The supplier reports ISO 9001 and ISO 14001 management-system certifications, plus production-license and network-certification credentials for wireless transmission equipment. Production evidence includes three production lines and annual FM transmitter output of 2,000 pieces, while quality-control staffing is reported at fewer than five employees. ZHC exports to multiple global regions and has held self-operated import/export rights since 2008. Overseas service infrastructure, detailed innovation results, customization services, raw-material traceability, and customer cases are not sufficiently documented. The SGS audit record shown expired on 2024-11-08, so it does not establish current audit validity.

Supplier typeThe supplier is identified as a manufacturer/factory and a limited company, with its business categorized in manufacturing, although one record also labels it as a trading company. Its stated operations and product information support a manufacturing role, but the conflicting classification should be clarified during verification.

CertificationsZHC reports ISO 9001 and ISO 14001 certifications, as well as wireless transmission equipment production-license and FM Radio & TV equipment network-certification credentials. An SGS audit record exists, but its stated validity ended on 2024-11-08, so current audit status is not confirmed.

After-Sales capabilityThe company explicitly states that it provides engineering installation and after-sales service and describes service as customer-oriented. However, overseas warehouse, showroom, agent/branch, and offline trade-show capabilities are all marked unknown, leaving the scale and geographic coverage of after-sales support unverified.

R&D capabilityZHC states that it conducts R&D, emphasizes independent innovation, and has assembled technical and management personnel; R&D engineers reportedly have 11–20 years of total experience. Nevertheless, new-product launches and detailed R&D outcomes are unknown, so innovation strength cannot be fully assessed.

Production capacityThe supplier reports production of FM and TV transmission equipment, three production lines, and annual FM transmitter output of 2,000 pieces. Its production-license certification and stated manufacturing activities support an established production capability, although quality-control staffing is limited to fewer than five personnel.
