Based on the DT220 TECH platform, plus the professinal stage class capsule MIC, excellent on bass. Supports SM58 & BATE58 V7 Capsule.
| Digital Audio UHF Wireless System | |
DWM245&m47 Digital UHF Wireless Microphone (with m47 Capsule) (2025 Edition) |
4th Generation Digital Audio UHF Wireless Tech
Application Scenarios
1. Pick up and forward sounds from various sound sources on stage (instruments, harmony, chorus); 2. High-end meeting scene. 3. Professional stage performance 4. with m47 Cartridge Capsule MIC, which refer to SM58, and excellent on bass. |
Characteristics
▪ Based on "DT220 TECH" digital U-segment wireless audio technology, it features stage studio-level sound quality, anti-interference, anti-crosstalk, high fidelity, high signal-to-noise ratio, low noise floor, and excellent wireless transmission distance. ▪ Digital U-segment technology, the effective wireless transmission distance is up to 70 meters, effectively avoiding intermodulation interference. ▪ Ultra-low power consumption, battery life >7 hours (lithium battery), standby time >20 hours. ▪ Using "hybrid power" patented technology, it can be powered by 3.7V 14500 lithium battery or 1.5V AAA AA battery. ▪ Used with a receiver with built-in lithium battery, it can be easily used outdoors. ▪ Used with high calss professional capsule. ▪ Supports SM58 & BATE58 V7 Capsule. |

Comparing Testing (working with DTR228-1R Receiver)
Common Problems
1. When using a rechargeable lithium battery with poor performance, its voltage reduction circuit will interfere with the performance of the receiver. 2. When multiple sets of equipment are used at the same time, if the frequency point is set improperly, it is easy to cause performance degradation due to intermodulation interference. |
