Wireless Microphones
◆ Four-channel high-speed automatic feed-suppressor signal using
a powerful processor combined with factory patented algorithm to
suppress acoustic feedback occurs. It uses echo cancellation and
eliminate reverberation algorithms effectively filter room
reverberation, in order to achieve the purpose of elimination of
acoustic feedback before acoustic feedback occurs, you can get up
to 12dB of additional gain, depending on the acoustical environment
and the selected action mode. The change in frequency of the output
signal of 5Hz, can detect the signal components resulting in reverb
and feedback appeared before it was removed, while maintaining the
original signal intact, achieved without diacritical by shielding the
noise to the output signal, and / or non-metal tail. High school low
grades input level selection, to prevent distortion of the peak input,
effectively increase the microphone pickup range 30 ~ 100CM. With
LCD display mode, you can view real-time to the site usage.
4-channel input (balanced line input / microphone input, or select
the 4-channel unbalanced inputs 6.35), for maximum compatibility
with different devices on different occasions needs. Provides 48V
phantom power switch to select the module can provide power to
four phantom microphone.
◆ This product is suitable for a variety of large and small conference
rooms, lecture halls; multimedia classroom PA; KTV rooms, a variety
of large concerts and other occasions.

said in a rapid correction state.
③·LCD status, the bypass / work switch state, as represented in the
arrows pointing BYPASS bypass state, such as an arrow pointing to
the "ACTIVE" indicates active. When the input signal level exceeds
the rated range, "PRESENT" box Anti Baichang Liang (voice Omitted
straight this time, should be appropriate to reduce the input signal
level)。

all the devices connected correctly.
②·Open Mic (recommended in the meeting room at the same time
open microphones at different locations around four), and
slowly turn up the volume and then began to speak, the scene
when they heard a slight whistle, open ACTIVE, then slowly
turn up the volume, tone when the bout to whistle a little tune
down the volume, and then click on the "CALIBRATE" Quick
calibration button (at this site to keep quiet), the speaker will
send out 1.5 seconds or so "rustling" noise (this is the machine
is scanning live acoustic environment), sweep seedlings has
been completed, you can start the meeting.
③·Special Note: Turn the microphone to speak, if the display
"PRESENT" anti-white box indicates the input level is too
large, should reduce the level of the input signal (the
microphone volume decrease) in front of the device, to avoid
signal distortion (if the field loud enough, you can adjust the
mixer or amplifier suitable large).
④·Please correct "Input level select switch." "HIGH" High-level
input (such as wireless microphones, condenser microphone,
etc.), MED in level inputs, LOW LOW input (such as a wired
dynamic microphones)
