BM-5/E1 безжичен инструментален микрофон
Using UHF 460-990 MHz band to avert interferencing frequency.
Automatic frequency scan feature searches for available frequencies
PLL system. Preset 16 non-interfered channels.
The receiver support DC power supply and AA batteries.
ALL using SMT, more stable function.
High efficiency batteries consumption design, so the handheld could
be in using for 5 hours continuously.
Long est distance: 60m, Ideal distance: 40m.
It is suitable for Erhu, Violin, Saxophone usage.
