FEATURE:
- BUILT IN RECHARGING
UNIT FOR 9V BATTERY
- Using VHF 170~270
MHz band to avert interference frequency.
- Using multilevel
high frequency and mid frequency narrowband filter,
so as to dispel and any possible interference signals.
- All audio of quartz
crystal oscillating, have very high frequency stability.
- With audio compressing-expanding
technology, the machine can lower noise and increase
the dynamic range
- With the function
of aborting the noise of feedback, it can effectively
reduce the screechy.
- A specially designed
circuit switch is on the phone. It is for clearing up
waves of miscellaneous signals.
- The inside circuit
which can eliminate the noise of switch on/off blocking
any noise when you switch on or off, also to protect
your expensive speaker.
- Uniform cardioids
pickup pattern isolates the main sound source and
minimize background noise.
- effective, Built
-in spherical wind and pop filter.
- Selected the good
crystal and components which make the timbre more clear.
- Longest distance
in open 100m. Idealist distance in open 50m.
