CD-4 Desktop 4-Channel Charging DockDesigned for the IR-300H infrared handheld microphone
Four independent charging channels, Type-C 65W fast charge and pure copper contacts, built to keep a fleet of microphones ready in meeting rooms and training centres.
Four Independent Channels
Two IR-300H microphones and two 18650 cells charge at the same time, each on its own channel, so a whole set is ready without waiting in turn.
No interference between baysType-C Fast Charge
Type-C input with support for 65W adapters and above cuts overall charging time, keeping pace with all-day, high-intensity use.
Rapid turnaroundAnti-Oxidation Contacts
Pure copper springs in the microphone bays and nickel-plated plates in the battery slots give stable contact, wear resistance and strong conductivity.
Copper and nickelCompact Desktop Body
A small rectangular footprint saves desk space, and front-facing LEDs make it a natural fit for meeting rooms, studios and podiums.
Space saving- Precise output control — microphone bays output DC 5V 500mA and the 18650 slots DC 5V 800mA, protecting battery health and preventing overcharging.
- Pure copper spring contacts — the microphone bays use dedicated copper springs that flex to meet the IR-300H base contacts for a stable, wear-resistant connection.
- Nickel-plated battery plates — the 18650 slots resist oxidation and conduct well, extending the service life of standard cells.
- Intelligent status LEDs — red means charging, green means full or an empty bay on standby, so the state of each device is visible at a glance.
- Wide input compatibility — DC 5V 4A input works with any Type-C adapter rated 65W or above, adapting to different power environments.
- Built-in protection — overvoltage and overcurrent circuits cut the output automatically if abnormal heating or indicator flashing is detected.
Built for: IR-300H Infrared Handheld Microphone
The CD-4 is the natural partner for the IR-300H, designed for centralised device management wherever the microphone is used heavily, such as meeting rooms and training centres.
- Made to fit — the copper spring contacts are sized for the IR-300H base, so the microphone charges the moment it is set down.
- 850nm infrared transmission — the IR-300H uses infrared rather than radio, removing the crosstalk and interference of conventional RF microphones.
- Dynamic pickup — a high-quality dynamic cartridge tuned for the human voice, suppressing ambient noise and howling.
- A/B dual channel — two independent frequencies let two microphones work in the same room without intermodulation interference.
- Long runtime — a single 18650 cell charges in about 2.5 hours on the CD-4 and then delivers up to 6 hours of continuous use.
- Robust body — infrared-transmissive flame-retardant PC plastic with high-strength aluminium alloy gives a solid feel and impact resistance.
Build a Crosstalk-Free, High-Fidelity Audio Space
The IR-300H keeps every speech clear, and with the CD-4 dock it stands up to heavy daily use in meeting and training environments.
