ER-5900 UHF True diversity twin receiver wireless mic system
The ER5900 dual-channel true diversity wireless microphone system is equipped with a wide frequency response and can be paired with any desired handheld microphones, headset microphones, desktop gooseneck conference microphones and so on to use in places like classrooms, conference rooms, KTVs and etc.
Configuration—Receiver: ER-5900; Bodypack transmitter: ET-50; Desktop transmitter: UD-2;
- The ER-5900 was self-developed by Relacart and you can choose a flexible assembly of the handheld microphone, bodypack transmitter or headset microphone, or desktop gooseneck conference microphone.
- The handheld microphone adopts the latest auto-mute, auto drop-to-mute, auto-off function;
- Adopts true diversity FM super-heterodyne reception to ensure the stability when receiving RF signals and the anti-interference of the receiver itself; the operating frequency range is from 521MHz to 938MHz.
- The receiver comes with the electronic volume adjustment, the adjustment range is -6dB to +18dB, +3dB each step.
- Selected channel group mode, each frequency band provides 50 channel groups for your selection.
- 128MHz wideband transmitter, four different frequency band receivers can be used interchangeably, which greatly facilitates KTV debugging and management.
- Matches Relacart’s classic audio companding circuit to minimize the noise from the interfering radio waves, and to ensure the maximum pickup effect of the product in use.
The BNC antenna can be connected to the coaxial antenna and the extended antenna and provides the antenna power supply voltage. It can be connected to the Relacart classic antenna distribution system, expanding the multi-device, enhance the receiving distance and improve the signal stability.
