IA25U

7

Input / Output Connections

The IA25U 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 (other sound sources) to the unit ,make sure that the DVD player has a RCA cord coming from it’s output and 

that this cord is plugging into the RCA Input on the rear of the IA25U. 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 INTO THE RCA INPUT JACK .

AS THIS COULD DAMAGE THE IA25U. NO OTHER AMPLIFIER IS NEEDED TO POWER YOUR SIGNAL IN 

ADDITION TO THE IA25U. ALWAYS MAKE SURE THAT THERE IS ONLY ONE AMPLIFIER INTHE SIGNAL PATH.

There are also input jacks for a MP3 player, USB and SD card on the front panel of the IA25U. Just plug the MP3 

player, USB or SD card into their respective input jacks and set the IA25U to the corresponding input. Be sure that

the volume of your MP3 player and IA25U are turned down at first and then slowly raise the volume to prevent

damaging the speakers or any of your other equipment.

Connecting the Signal Source to the IA25U (DVD/MIXER/MP3 etc.)

The IA25U 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 IA25U.

Connecting the IA25U to Passive Loudspeakers

NOTE: WHEN MAKING THESE CONNECTIONS THE POWER OF THE IA25U AND THE SIGNAL 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 

IA25U OPERATED MOST EFFICIENTLY WHEN USED WITH 8 OHM SPEAKERS.
