BNK BK8400 Conference Microphones

Key Features

• It’s a 4-channel UHF wireless microphone system, capable of supporting up to four handheld transmitters simultaneously.

• The receiver offers multiple outputs: according to one listing it has 4 balanced XLR outputs (one per mic) plus a mixed unbalanced ¼″ (6.35 mm) jack output.

• The wireless frequency coverage is in the UHF band. One listing quotes 530-590 MHz, with 200 selectable UHF channels. Another lists “UHF600-850 MHz” for the transmitter.

• Audio frequency response seems to be in the ~50 Hz to 15 kHz region.

• Operating range (under typical conditions) is quoted around 50 meters (though other listings suggest longer).

 Why This Could Be Good for Conference / Multi-Mic Use

• With four channels, you can have multiple speakers, panelists or presenters using wireless handheld mics at once — which is ideal for conferences, meetings or events.

• Balanced XLR outputs allow direct integration into professional audio mixers or PA systems, which makes it suitable for higher-quality setups.

• The UHF wireless band offers better performance in crowded RF environments (relative to older VHF systems) — helpful in conference centres with many devices.

• The ability to select among many channels (200 selectable) gives flexibility to avoid interference.

• The wide audio frequency response (down to ~50 Hz) means it can capture full speech dynamics (and perhaps the lower end of voices) rather than just “thin” audio.

• The “pay-attention” spec of decent range (50 m) means it can support reasonably large rooms, though you still need to check environment/line-of-sight.

 Considerations / Things to Check

• The quoted “50 m” range is “under typical conditions” — real venues with walls, interference, other wireless devices may reduce it. If your conference room is large or has many obstructions, you might need to test.

• UHF frequency allocations vary by country; you’ll want to check that the specific frequency band (530-590 MHz or 600-850 MHz depending on listing) is legal and free to use in your region (Kenya).

• Wireless systems are more prone to interference than wired mics — ensure you have a plan for channel scanning, possibly backup, and good receiver placement.

• Handheld microphones are great for presenters, but if you wanted lapel/lavalier or boundary mics (for e.g., panel tables) you’ll need to check compatibility or additional transmitters.

• Build quality, stability and durability might be less than high-end professional systems — for heavy use, check reviews or test in your environment.

 Summary

In short: the BK8400 is a fairly capable mid-level 4-channel wireless handheld mic system, suitable for conference / meeting use where you want multiple wireless mics feeding a mixer or PA. It offers good flexibility (4 XLR outs, UHF band, multiple channel selection) and could meet many event setups. If you’re running a smaller to medium sized room and need wireless mics for say 3-4 speakers, it’s a solid option — assuming you’ve verified compatibility/frequency legality, and tested the coverage in your venue.
