The K 280FS is specified as a 2-channel wireless microphone system. It is therefore positioned for two microphone channels, but the exact transmitter combination should be confirmed when ordering. Handheld, lavalier and headworn options are listed. Do not assume additional microphones can be added to the same receiver without written confirmation.

The product family frequency range is stated as 620–950 MHz, while the exact operating band is not fixed in the available product information. Confirm the selected model specification before purchase. Buyers must also verify whether that frequency version is suitable and permitted in their destination market.

A 60 m distance is stated for the K 280FS. This should be treated as the product information’s stated distance, not a guarantee for every venue. Walls, people, antenna placement and other RF equipment can affect performance. For a church, wedding hall or event installation, confirm expected real-world coverage.

It can be considered for churches, weddings, schools, karaoke, conferences and event venues because it provides two wireless microphone channels and lists DSP anti-howling and automatic frequency shift. Suitability still depends on the venue, frequency legality, receiver connections and selected microphone type. Confirm the complete configuration before use.

USB-C charging is listed among the product features. The available information does not specify which components charge through USB-C, charging time, battery capacity or runtime. Confirm the selected model specification, included charging cable, power adapter and battery arrangement before relying on it for long services, events or rental bookings.

The product information does not state the receiver’s output connectors, so compatibility with a particular mixer, amplifier, powered speaker or karaoke system cannot be guaranteed from the available facts. Confirm the receiver output type and cable requirements before purchase, especially when replacing an existing wireless microphone system.

The listed microphone options are handheld, lavalier and headworn. The appropriate choice depends on whether the application is singing, MC work, presentations, worship or hands-free speaking. Confirm which option is included in the quotation, along with connector details, accessories and whether the selected option is available for the required order quantity.

DSP anti-howling is listed as a K 280FS feature, which is relevant when managing feedback risk in church, event and presentation systems. It does not eliminate the need for suitable speaker placement, microphone technique and gain settings. Confirm the operating controls and recommended setup for the selected receiver and microphone configuration.

The product information does not state a fixed MOQ. Small-batch and trial-order evaluation may be possible subject to current factory conditions, and mixed-model purchasing can be coordinated where practical. Request confirmation of the current MOQ, sample availability, price breaks, lead time and packaging options for your target market.

Mixed-model purchasing can be coordinated where practical, but the available information does not define the permitted combinations or quantities. Confirm the selected model specification, minimum quantities, carton requirements and production schedule with YH-AUDIO. OEM logo and packaging options also depend on configuration and order quantity.

The K 280FS family is listed with a 620–950 MHz frequency range, while the exact band must be specified and reconfirmed. Distributors should provide the destination market before quotation so the selected version can be reviewed for local suitability. Do not advertise regulatory compliance until the required market documentation is confirmed.

Request confirmation of the exact frequency band, channel configuration, receiver outputs, microphone type, USB-C charging arrangement, included accessories and destination-market requirements. The published figures include 40 Hz–18 kHz response, ±0.005% frequency stability, 250 kHz channel spacing, 100 dB dynamic range and a stated 60 m distance.

OEM logo and packaging options are available subject to configuration and quantity, but specific artwork, language, carton design and order thresholds are not stated. Distributors should submit the target market, branding requirements and expected volume. Confirm approval samples, packaging specifications, manual language, MOQ and lead time before committing to a private-label program.

The product information does not provide a spare-parts list or guarantee separate replacement transmitters, receivers, antennas, adapters or microphone components. Distributors should request confirmation of available replacement parts, pairing or compatibility procedures, pricing, lead times and warranty handling before stocking the K 280FS for rental or retail support.

Distributors must confirm frequency legality and any required certification or import documentation for the destination market. The product description specifically says compliance should be confirmed and does not provide country approvals. Before shipment, request the selected model specification and applicable documentation for Nigeria, South Africa, Mexico, Brazil or Saudi Arabia.

The available product information does not state a standard warranty period, DOA policy or replacement timetable. Distributors should request these commercial terms together with lead time, sample policy, technical documentation and spare-part support. This is especially important for rental companies, installers and retailers that need predictable service after the initial order.
