Typical IA1200 Input and Output Connections

In the typical setup, a user should wire from the output of the signal source directly to one of the RCA inputs on the rear of the IA1200. Once the input signal source is connected to the IA1200, connect the loudspeakers to the IA1200’s main outputs. Pictured above is a TV and DVD player connected to the IA1200 inputs. The IA1200 has two loudspeakers connected to it which will play the signal from either the TV, DVD, USB flash drive, SD Card, or MP3 player.

The LINE OUTPUT is connected to the input of a tape recorder. The output of the tape recorder is connected to the input of another amplifier. You can bypass the tape recorder and connect the LINE OUTPUT directly to the input of another amplifier. The LINE OUTPUT will send the signal from the selected input (AUX, DVD, USB flash drive, SD card, or MP3 Player).
NOTE: WHEN MAKING THESE CONNECTIONS THE POWER OF THE IA1200 AND THE SIGNAL SOURCE SHOULD ALL BE IN THE OFF POSITION WITH THE VOLUME LEVELS TURNED DOWN.

Input / Output Connections

Connecting the Signal Source to the IA1200 (DVD/MIXER/MP3 etc.) The IA1200 has two input jacks on the rear of the unit which is designed to receive the signal directly from your DVD, mixer, or any of your other 2 Channel signal sources. To ensure that you have correctly connected your DVD player (and other sound sources) to the unit, make sure that the DVD player has an RCA cord coming from its output and that this cord is plugging into the RCA Input on the rear of the 1A1200. Ensure that the polarity of your signal is always maintained by using color-coordinated RCA cables.

NOTE: BE SURE NOT TO CONNECT AN AMPLIFIER OR ANY AMPLIFIED SIGNAL TO THE RCA INPUT JACK. AS THIS COULD DAMAGE THE IA1200. NO OTHER AMPLIFIER IS NEEDED TO POWER YOUR SIGNAL IN ADDITION TO THE IA1200. ALWAYS MAKE SURE THAT THERE IS ONLY ONE AMPLIFIER IN THE SIGNAL PATH.

Connecting a USB Flash Drive / SD Card to the IA1200
There are also SD Card and USB flash drive inputs on the front panel of the lA 1200. The maximum size of the SD Card or USB flash drive is 32GB. If your memory card exceeds 32GB, the unit will not be able to read the files from the memory cards. You will only be able to play .mp3, wav, and WMA files directly from these memory cards once they are inserted into the front panel of the unit. Press the play/pause button on the front panel of the unit to begin playing files from your USB /SD Card, press this button again to pause. Press the NEXT button to move to the next track on either the USB or SD Card. Press the PREVIOUS button to move to the previous track on either the USB or SD Card.

NOTE: THE USB INPUT WILL ONLY CONNECT TO A USB FLASH DRIVE. DO NOT ATTEMPT TO CONNECT THE USB INPUT DIRECTLY TO A COMPUTER AS THE IA1200 WILL NOT BE ABLE TO PLAY FILES DIRECTLY FROM A COMPUTER VIA THE USB INPUT. BE SURE NOT TO HOOK UP AN AMPLIFIER OR ANY AMPLIFIED SIGNAL INTO THE RCA INPUT JACK AS THIS COULD DAMAGE THE IA1200. NO OTHER AMPLIFIER IS NEEDED TO POWER YOUR SIGNAL IN ADDITION TO THE IA1200. ALWAYS MAKE SURE THAT THERE IS ONLY ONE AMPLIFIER IN THE SIGNAL PATH.

There are also input jacks for an MP3 player, USB flash drive, and SD card on the front panel of the IA1200. Just plug the MP3 player, USB flash drive, or SD card into their respective input jacks and set the IA 1200 to the corresponding input. Be sure that the volume of your MP3 player and IA 1200 are turned down at first and then slowly raise the volume to prevent damaging the speakers or any of your other equipment.

Connecting Microphones to IA1200
There are two ¼” inputs on the face of the unit which you can plug microphones or line-level devices directly into. To use, simply plug the microphones into the / inputs while the speaker and microphones are in the OFF position. Once plugged in, power on the unit and microphones. Once turned on, simply turn up the Microphone Volume (7) to the desired levels.

Connecting the IA 1200 to Passive Loudspeakers
The IA1200 is designed to power up to two full-range passive loudspeakers. The speakers should be connected via the speaker wire outputs on the rear of the IA1200.
NOTE: WHEN MAKING THESE CONNECTIONS THE POWER OF THE IA1200 AND THE S/GNAL SOURCE SHOULD ALL BE IN THE OFF POSITION WITH THE VOLUME LEVELS TURNED DOWN. ONCE THE UNITS ARE ALL POWERED ON, SLOWLY INCREASE THE VOLUME TO AVOID DAMAGING ANY OF YOUR EQUIPMENT. THE IA1200 OPERATED MOST EFFICIENTLY WHEN USED WITH 8 OHM SPEAKERS.
