AMP Five Series
Monoblock Amplifiers
Owner’s Manual
Multichannel power amplifiers have become the solid foundation
upon which the best home sound systems are built. In the AMP Five
series, AudioSource has designed the most unique line of multichannel
power amplifiers available. The AMP 5.1, 5.2 and 5.3 are completely
modular within their optional 19-inch rack mount chassis. The ability
to place and replace several monoblock amplifiers gives the AMP Five
series unsurpassed flexibility. From powering an entire home theater
to driving in-wall speakers throughout an entire home, the AMP Five
series offers the kind of versatility others only dream about.

Signal LED
This light indicates that a signal is
present at one of the inputs.
Protect LED
This light indicates when the unit is
o v e rheated, or when a shorted load or
DC is detected in the amplifier output.
The amplifier will reset itself when the
p roblem is corre c t e d .
Peak LED
This light indicates when the unit is within 3dB of clipping. Occasional blinking
of this light is normal, but if it remains
lit for more than a few seconds at a time,
you should either turn down the level
c o n t rol of the AMP Five module or
reduce the output level of the component
feeding the AMP Five module. This will
avoid audible distort i o n .
Volume Control
This dial adjusts the output to the speakers.
Low Cut Control
This button may be used to filter the lowest frequencies from your speakers. This feature is useful when the
speakers driven by the AMP Five module are small and/or when your system has a powered subwoofer to
re p roduce the low bass signal.
Phase Control
This button switches the polarity of the speaker outputs. As speakers are sometimes placed quite a distance
from each other, their sound may arrive at your ears milliseconds before or after that of the other speakers.
(Setting the phase at 180º compensates for those rare occasions in which your speakers are out of phase,
resulting in a hollow sound.) The default setting for the phase switch is 0º, and once set, it should not need
to be adjusted. Note: Phase is relative and can be different from location to location. Always return to the
normal listening location to evaluate any setting changes.
Power Switch
This switch turns the AMP Five module on or off. Its status is indicated by the light within the switch.
Monitor Jack
This quart e r-inch jack allows you to connect headphones to the AMP Five to monitor the input signal.
Balanced Input Jack
This input allows components with XLR outputs to connect to the AMP Five module.
Unbalanced Input/Output Jacks
This input allows components with RCA outputs to connect to the AMP Five module. This input should be
used when the signal will be passed on to another module or other power amplifier.
Speaker Output Jacks
These inputs should be connected to the speaker which will be driven by the AMP Five module.
AC Input/Output
Use an AC cord to connect to an AC socket. You may daisy chain a number of AMP Five modules, as shown
