LINE OUTPUT 

To tape record your speech or program, connect the 

LINE OUT

 on the amplifier (using cable with 

standard 3.5mm plug) to the input on a tape recorder. Additional S1202 powered companion speakers 
may also be connected to the 

LINE OUT 

jack. 

 

INTERNAL SPEAKERS

 

The internal speakers are wired for stereo, 

LEFT 

and 

RIGHT 

channel information is reproduced by the 

appropriate speaker inside the unit. 
 

EXTERNAL SPEAKERS

 

Two separately amplified speaker jacks allow you to use one or two S1201 speakers for additional sound 
power.  
 

PROBLEM SOLVING 

Feedback is the howl or screech often heard in sound reinforcement systems.  It is caused by sound from 
the loudspeaker returning to the microphone.  AmpliVox systems utilize proven acoustical principles to 
minimize this; however, there is no way to completely eliminate feedback under conditions of high 
amplification.  If feedback occurs check the following: 
1. 

 

User’s hand covering the head of the microphone.  [Hold microphone under head slots.] 

2. 

 

Sound can easily re-enter microphone. Keep loudspeaker turned toward audience. Note: sound can be 
reflected from a hard surface back through the microphone. [Turn speaker.] 

3. 

 

User holding microphone in a reflecting position. [Turn microphone.]  

4. 

 

Volume setting too high at main unit. [Reduce microphone channel volume or if using Kima wireless 
companion speaker option, that the transmit level is properly adjusted; compensate by speaking 
louder or closer to the microphone.] 

 

NO SOUND

 

Make sure amplifier 

POWER

 switch is turned on and red LED is lit. If switch is on and LED is not lit, 

check to see that batteries are properly connected and at full charge. If using optional power adapter, 
check to see that front panel connector is properly seated, and verify that the power source is live.  If 
using the Kima wireless speaker transmitter model S1670, make sure a signal source (CD player, cassette, 
MP3 player, line output from another sound system, etc.) is plugged into the 

AUDIO IN 

jack, and that 

the transmitter is turned on, the volume turned to maximum and has 4 fresh  “AAA” Alkaline batteries 
installed or the external power transformer is plugged in and working. 
 

 

NOTE:  There will be a short noise burst from the S1204 speaker every time the S1670 Kima 

wireless transmitter is turned on or off.  This is a normal function of the built in receiver acquiring the 
desired signal.  To avoid undesirable operation it is recommended that the Kima transmitter be turned on 
first before the S1204, and that the S1204 be turned off first before the Kima transmitter to avoid 
unwanted loud noise bursts.  If for any reason the Kima transmitter frequency is changed from position 
‘A’ as shipped from the factory, the S1204 must be turned off and then back on for the receiver to acquire 
the proper signal.
