Front Panel Controls

Power

This front panel button switches the AMP One/A on or off. A multicolored LED indicates its power status.
Note: This amp uses a two-stage soft startup. The amp will power up in standby mode. When its power supply stabilizes, after
a few seconds, it will become fully operative.

Input Level Controls

These knobs adjust the incoming signal level and thereby act as volume controls. We recommend that you
leave these on max and use your signal source (receiver, CD player, preamplifier, etc.) to adjust the volume.
Hooking up the Wires
Audio signals travel out of one component and into another. All of your connections should also go from out to in.

Line In

Connect the line out jacks from your signal source (receiver, CD player, preamplifier, etc.) to the line in
jacks on the AMP One/A.

Line Out/Thru

If you are using multiple amplifiers in your system, the AMP One/A features a stereo pair of Line Out/Thru
jacks to send the original signal directly to these additional amplifiers.

Bridging Switch (refer to wiring diagram)

In addition to providing 80 watts RMS per channel in the stereo mode, your AMP One/A can be used as a
high power mono amplifier, providing over 200 watts RMS. This can be accomplished by sliding the bridging
switch from the stereo position to the mono position. For mono applications, use only the right channel input.
Similarly, use only the right channel input level control.
Note: Be sure to observe the correct speaker connections for bridged applications. Because of the high power output in this
mode, we recommend initially setting the right level control at "min", and then adjusting the volume to the desired level.

Speaker Terminals

One pair of speakers can be used with the AMP One/A. This amp uses five-way binding post speaker
outputs. The speaker terminals are color coded. Red posts indicate positive (+) terminals and black posts
indicate negative (–) terminals. Be sure to connect the positive output terminals of your AMP One/A to
the positive input terminals of your speakers and the negative output terminals of your AMP One/A to the
negative input terminals of your speakers.
Note: On some units, the labeling of the left and right speaker terminals has been reversed. Refer to the wiring diagrams on the
next page for proper connection of speaker cables.
