Operation

6

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.
