Getting Started

The following steps will help you set up your 

loudspeakers quickly.

INITIAL SETTINGS:

1.  Turn the LEVEL control on the rear panel all the 

way down.

2.  Set the EQ ON/OFF switch out (OFF).
3.  Turn the POWER switch OFF.

CONNECTIONS:

1.   Connect the line-level signal from your mixer (or 

other signal source) to the INPUT jack on the    
TH-12A rear panel (XLR connector).

2.  Connect the supplied AC power cord to the IEC 

socket on the back of the loudspeaker. Plug the 
other end into an AC outlet properly configured with 
the correct voltage as indicated just below the IEC 
socket.

TURN IT ON:

1.   Turn the POWER switch ON.
2.  Start your signal source (mp3 player, CD, DAW, 

band, or whatever), but leave the master level 
control on your mixer down.

3.  Slowly turn up the LEVEL control on the TH-12A to 

the “U” (unity gain) mark at the center position.

4.  Adjust the master volume on your mixer to a 

comfortable listening level. If the volume from the 
speakers gets really loud, really fast, try turning 
down the LEVEL control on the TH-12A a bit. If the 
speakers don’t get loud enough, turn up the LEVEL 
control to achieve a good balance of master volume 
control and loudness from the speaker.

Now that you have your loudspeakers working, it’s 

time to hunker down and read the rest of this manual…
especially the following:

ADDITIONAL TIDBITS OF WIDSDOM:

•  Never listen to loud music for prolonged periods.  

     Please see the Safety Instructions on page 2 for  
    information on hearing protection.

•   When you shut down your equipment, turn off the  

       TH-12A loudspeakers first to prevent thumps  
       and other noises generated by any upstream   
       equipment from coming out of the speakers.   
    When powering up, turn on the TH-12As last.

•   Save the shipping boxes and packing materials!  

    You may need them someday. Besides, your    
    cat will love playing in them and jumping out at  
    you unexpectedly. Remember to pretend like you  

    are surprised!

•   Save your sales receipt in a safe place.

•   Record the serial number in the space provided on  

    page 3, along with where and when you bought it.
