OUTPUT

To connect to the wireless speaker transmitter, or 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.

EXTERNAL SPEAKERS

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

INTERNAL SPEAKERS

The internal speakers are wired for stereo, LEFT and RIGHT channel. Sound is reproduced by the appropriate speaker inside the unit.

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 900MHx wireless companion speaker option, make sure 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 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 and a fresh “9v” Alkaline battery is installed or the external power transformer is plugged in and working.
