Operation
Operation of the PA5800 is simple. There
are no controls to adjust once the instal-
lation is complete.
After all connections have been made to
the amplifier’s inputs and speaker termi-
nals, connect the amplifier’s power cord
to an AC outlet. Make certain that the
PA5800 power switch is in the off position
before plugging in the power cord.
At this point you are almost ready for lis-
tening. First, turn on the source compo-
nents and processor in your system. It is
always a good idea to turn on your
amplifier last. This avoids the possibility
of any turn-on pops or transients from
other equipment being amplified and
sent to your speakers, where they may
cause damage. Always start with a low
volume level on your controller or pre-
amp to avoid damage to your speakers.
Manual Operation
If the unit is not being used with the
automatic, remote turn-on system and
the AC power plug is connected to a live
outlet, the ring surrounding the power
switch will glow red. This is your indica-
tion that the unit is functional.
To place the unit in operation, simply
depress the power switch. Note that the
ring surrounding the power switch will
glow green. There may be a short pause
between the time the power switch is
turned on and power is applied to the
speakers. This is intentional, and this
feature protects your speakers from dam-
age as the amplifier stabilizes.
You are now ready to enjoy the finest
sonic performance available. All volume
and level adjustments are made at your
preamp, controller or surround processor.
To turn the unit off, press the front panel
power switch.
For Automatic Operation
Before proceeding, make certain that the
connection between the PA5800 and
PT2500 or other trigger source has been
properly made as outlined previously. At
this point the triggering unit should be
turned off.
Plug the PA5800 into a live AC power
source. The ring surrounding the power
switch will glow red. Press the Power
switch once and note that the ring will
turn to amber. This is your indication
that the PA5800 is in standby mode.
Finally, turn on the PT2500 or other
device used to trigger the remote amp
trigger, such as a wall-mounted AC
adapter. The PA5800 will respond to the
trigger signal by automatically turning
on, and the ring surrounding the power
switch will turn green. There will be a
short pause after the signal is applied
and the indicator changes color, and the
power will be applied to the speakers.
This pause is intentional to protect your
speakers from damage as the amplifier
stabilizes.
Once your system is turned on, you are
ready to enjoy the finest sonic perfor-
mance available. There are no controls
to adjust. All volume and level adjust-
ments are made by your preamp, con-
troller or surround processor.
At the conclusion of your listening ses-
sion, there is no need to manually turn
off the PA5800. When the PT2500 or
other triggering device is turned off,
removing power from the trigger jack,
the PA5800 will return to the standby
mode.
Important Note: If you will not be
using your audio system for an extended
period of time, such as during a vaca-
tion, it is always a good idea to turn the
unit off using the power switch. This will
prevent the automatic turn-on circuits
from accidentally turning the system on
during your absence.
