The YH-K8004 is specified as a four-channel wireless microphone system. This identifies the product configuration, but the product facts do not describe channel coordination, frequency spacing or the number of complete systems that can operate together. For a church, wedding, karaoke venue or rental job, confirm the selected model specification and venue frequency plan before ordering.

The listed family range is 530–950 MHz, while the exact operating band is stated as requiring confirmation. The system uses FM modulation. Buyers should not treat the full family range as the supplied operating frequency. Confirm the selected model specification and verify whether that frequency version is suitable and legal for the destination market.

The product facts list balanced output at −20 dBV / 100 Ω and microphone output at −12 dBV / 5 kΩ, so output integration should be checked against the receiving equipment. The physical connector types are not specified. Confirm the selected model specification, cable requirements and input compatibility before connecting the receiver to a mixer, amplifier or powered speaker.

Each transmitter is specified to use two 1.5 V batteries. The product facts do not identify the battery format, runtime, low-battery indication or whether rechargeable cells are supported. For long church services, weddings, karaoke sessions or rental work, confirm the selected model specification and plan suitable replacement batteries before deployment.

The receiver specification lists DC 12 V / 1000 mA power. The supplied adapter, plug type, voltage tolerance and regional plug option are not stated. Confirm the selected model specification, included accessories and destination-market plug requirement before installation or shipment, particularly when preparing systems for fixed AV projects or mobile event use.

The K8004 uses dynamic microphones and is specified with a 50 Hz–15 kHz frequency response, FM modulation and THD of ≤1%. These are documented technical points for evaluating speech and vocal applications, but they do not guarantee a particular venue result. Confirm the selected model specification and test placement, mixer gain and loudspeaker setup for the intended church, event or karaoke use.

A tested operating range is not provided in the product facts. Performance can depend on venue layout, obstructions, antenna placement, interference and the confirmed frequency version. Do not rely on an assumed distance for a church, ballroom, school or outdoor event. Request a range specification or test guidance for the selected model before purchase.

Package contents are not specified. The product description indicates that frequency, voltage, plug and accessories should be reconfirmed before quotation. Confirm whether the order includes the receiver power supply, microphones, batteries, cables, antennas, manuals and any carrying or mounting items required for your application.

Distributors should confirm the current model version, exact frequency band, voltage and plug, accessories, package contents, MOQ, sample availability and lead time. The source information states that these details require reconfirmation before bulk ordering. Also confirm destination-market frequency legality, warranty handling, documentation and any OEM logo or packaging requirements.

Small-batch and trial-order evaluation is subject to current factory conditions. Mixed-model purchasing can also be coordinated where practical. Because no fixed MOQ is provided, request confirmation for the intended quantity, configuration and destination. A quotation should clarify sample availability, production lead time, packaging, payment terms and the specification of the supplied K8004 version.

OEM logo and packaging options depend on configuration and quantity. They are not guaranteed as standard inclusions. Distributors should provide the target market, logo files, packaging language, order quantity and desired configuration, then request confirmation of available artwork, MOQ, sample approval, lead time and any applicable setup costs.

No single country-specific frequency version is established in the product facts. K8004 has a listed family range of 530–950 MHz, with the exact band requiring confirmation. Importers must confirm the selected model specification and independently verify destination-market legality, approvals and operating requirements before placing a commercial order for Nigeria, South Africa, Mexico, Brazil or Saudi Arabia.

Available specifications include four channels, FM modulation, ±48 kHz maximum deviation, 50 Hz–15 kHz frequency response, THD of ≤1%, transmitter power of 10 mW, transmitter battery rating of two 1.5 V batteries, receiver power of DC 12 V / 1000 mA, and the listed output levels and impedances. Confirm the selected model specification before publishing a datasheet.

The product facts do not confirm separate replacement transmitters, receiver parts, antennas, power supplies or other spares. Distributors should request confirmation of available replacement items, compatibility with the supplied K8004 version, pricing, minimum quantities and lead times. This is important for rental fleets, installers and retailers planning after-sales support.

Yes, K8004 is presented for distributors, retailers, rental companies, installers and project buyers. That positioning does not confirm a specific durability rating, rack format, range or installation accessory. Procurement teams should confirm the selected model specification, package contents, warranty process, replacement-part support and suitability for their rental or fixed-installation workflow.

The product facts do not identify certifications, approvals or country-specific compliance documents. Distributors should request the current documentation package for the selected model and destination before import or marketing. Frequency legality, required approvals, labeling, manuals and local documentation must be verified separately rather than inferred from the 530–950 MHz family range.
