Input Connection 

 

The equipment provides 3 input jacks, which may be used for connecting other signal 
sources: CD, AUX, and Tape. A rotary switch at the front panel for the user to select desired 
input source. 
 
To connect microphone, insert the microphone plug into the jack on the rear panel. All 3 
microphones can be used.    But only the MIC 1 has voice priority function.    It will mute 
other input sources, when the user begins to speak.   
 
“Booster In” can also be connected for the signal from other mixer amplifier or pre-mixer 
amplifier.. 
 
 
 

 

Output Connection 

 

There are 2 pair binding posts on the rear panel for the connection of 8 ohm stereo speaker.   
Pay attention to the correct polarity of the speaker, while connecting.   
 

 

Preout Connection 

 

“Preout” jack is to connect the output signal (@ 1V) to other amplifier. 

 

 

Record Out Connection 

 

Connect “Record Out” jack to the record machine.    The “Record Out” signal is @1V. 

 

7. Operation

 

 
After all connections are completed, rotate CD/AUX/Tape Selection Switch to the input 
source desired.    Before turn on the power switch, make sure the master volume control is 
at proper position (not at maximum position) to avoid sudden loud sound.    Then turn on 
the power switch.   
 
Turn the master, bass, treble control to what you desire.    For the input signal, if necessary, 
turn the corresponding level control to your desire.
