Typical AMP8X 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 AMP8X.Once the input signal source is connected to the AMP8X,connect the loudspeakers to the
AMP8X’s main outputs. Pictured above is a DVD player connected to the AMP8X’s inputs. The AMP8X has two
Passive Loudspeakers (top) connected to it which will play the signal from DVD player. These speakers do not have
LED inputs and therefore will only transmit the audio from the AMP8X. The AMP8X also has two Technical Pro
Passive LED Loudspeakers (bottom) connected to it. Just connect the AMP8X's speaker outputs to the audio inputs
on the speakers, then connect the AMP8X's LED outputs to the LED inputs on the speakers. These speakers will
transmit the audio and LED outputs of the AMP8X.

NOTE:WHEN MAKING THESE CONNECTIONS THE POWER OF THE AMP8X AND THE SIGNAL SOURCE
SHOULD ALL BE IN THE OFF POSITION WITH THE VOLUME LEVELS TURNED DOWN

Input / Output Connections

The AMP8X has one RCA input jack 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 AMP8X. 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 AMP8X. NO OTHER AMPLIFIER IS NEEDED
TO POWER YOUR SIGNAL IN ADDITION TO THE AMP8X. ALWAYS MAKE SURE THAT THERE IS
ONLY ONE AMPLIFIER IN THE SIGNAL PATH.

Connecting the Signal Source to the AMP8X (DVD/MIXER/MP3 etc.)

The AMP8X is designed to power up to four full-range passive loudspeakers. The speakers should be
connected via the speaker wire outputs on the rear of the AMP8X.

Connecting the AMP8X to Passive Loudspeakers

NOTE: WHEN MAKING THESE CONNECTIONS THE POWER OF THE AMP8X 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 AMP8X OPERATED MOST EFFICIENTLY WHEN
USED WITH 8 OHM SPEAKERS.
