to listen the true of the world,you must follow your dream
· Whole metal(receiver & handheld microphone)
· Detachable antenna
· Wide frequency response, high S/N ratio.
· Resist disturbing strongly, volume stand by (noises output to zero)
· Super silent function, low T.H.D.
· No hitting when putting on the switch. thus can the amplifier and
· speakers be protected.
· With a complete working state and power level indicating.
· With a wide use range for over 30m in a good surrounding. for
· 20m in a duplicate one.
