K-9004 Product Features
1. Adopts UHF 8-channel multi-frequency design and high-precision full-digital pilot frequency technology for ultra-stable signal transmission.
2. Features 30MHz bandwidth and 300KHz channel spacing with 400 selectable channels, effectively resisting various environmental signal interferences.
3. The main unit is equipped with a 3.5-inch high-brightness color TFT display, dynamically showing real-time data including signal strength, volume, channel number, frequency point, field strength, battery level, mute state and automatic frequency scanning status.
4. Each microphone integrates a high-brightness TFT display, which dynamically indicates remaining battery, frequency, channel and audio level.
5. Supports 4-channel automatic frequency scanning, which filters interfering frequencies and selects optimal clean frequency points adaptively in complex environments.
6. Built-in independent 4-channel locking function prevents accidental parameter changes and misoperation, fully protecting customized settings.
7. Equipped with 4 independent XLR output ports and 1 × 6.35mm mixed output port, supporting independent volume adjustment for each of the 4 audio channels.
8. Provides a total of 5 adjustable audio outputs (4 independent channels + 1 mixed channel) with separate volume control for each channel, meeting diverse audio output needs.
9. Adopts four matched antennas for audio and data transmission, realizing stable and lossless sound quality transmission.
10. Features four independent jog dials for separate parameter adjustment of each display module, with dedicated display indicator switches for intuitive and convenient operation.
11. Supports multi-device simultaneous operation in the same environment; up to 4 sets (16 channels in total) can work concurrently on the same frequency band without mutual interference.
12. Wide compatibility supports mixed use of wireless gooseneck, headworn, lavalier and handheld microphones, adapting to diverse application scenarios.
13. Offers two switchable RF transmission power levels (high/low) for flexible adjustment based on working distance and operating device quantity.
14. Equipped with high-sensitivity gooseneck microphone rods with a maximum pickup distance of 1250px, delivering wide pickup range and high-fidelity sound quality.
15. Low-power design enables Ni-MH rechargeable batteries to support over 10 hours of continuous operation.
16. Built-in high-power ACT infrared frequency pairing module supports long-distance automatic infrared frequency matching.
