MAIN FEATURE |
Using UHF 400MHz band. |
Multilevel quiet control circuit, to avoid interference signal from outside open the mute system. |
Special design companding circuit, strongly improve S/N ratio. |
Using excellent dynamic cardioid direct cardiod direct cartridge, the timbre bright and clear. |
A specially designed circuit switch is on the phone, it is for clearing up wave of miscellaneous signals. |
High efficiency batteries consumption design. |
With audio compressing - expanding technology, the machine can lower noises and increase the dynamic range. |
