Azden Corporation 1200BT 사용자 설명서

Using either the UP or DOWN button [

l

] the desired receiving fre-

quency or channel number can be set. Tapping the button steps the
frequency or channel number one at a time while pressing and hold-
ing the button moves through the frequencies or channel numbers
rapidly. There are 188 different frequencies or channel numbers to
chose from. Once the desired frequency or channel has been deter-
mined be certain to set both the transmitter and receiver to match.

The POWER ON/OFF switch [

e

] turns the 1200BT On or OFF.

Prior to first turning the 1200BT ON  it is best to set the AUDIO switch
[

g

] to ST.BY (standby). When you are ready to begin transmitting,

switch to ON. The ST.BY position acts as a ‘mute’ that maintains the
RF signal but turns off the audio.

This 4-pin Hirose connector [

h

] is the microphone input. Azden pro-

duces a number of lapel, head-worn and neck-worn microphones
that are specifically suited for the 1200BT. In addition, other exter-
nally powered (5VDC) electret condenser microphones can be used
when they are properly wired with the correct Herosi connector (pin 1
is for audio +, pin 2 is not used, pin 3 is for bias voltage and pin 4 is
ground). If you are using the 1200BT as a wireless instrument trans-
mitter the connections are somewhat different (pin 1 is not used, pin
2 is the audio +, pin 3 is for bias voltage and pin 4 is ground).

This screwdriver adjustment [

♣

] controls the input level of the micro-

phone. Counterclockwise rotation reduces the input gain while clock-
wise rotation increases the input gain.

The metal beltclip [

c

] provides a convienent method of attaching

the transmiiter to the user.

The antenna [

d

] should be kept clear of metal objects.

In addition to showing the frequency and channel number, the dis-
play [

i

] also shows other useful information.
