Plugging in the

Power Cable

You may use either the provided power cable or an aftermarket power cable to connect your unit

to AC power. For best results, we strongly recommend the use of a PS Audio PerfectWave®

Power AC cable, or any high-quality aftermarket power cable. It is always preferable to feed your

equipment using an excellent power cable, as there will be a significant performance improvement

over the stock power cable.

Output Disable

Mode

When the logo button is not illuminated, the amplifier is in Output Disable Mode. Output Disable

Mode can be activated by pressing the front panel PS Audio logo button, located on the upper left

hand corner of the Stellar’s front panel. This mode keeps the amplifier in a reduced power mode,

maintaining excellent performance benefits while increasing power economy. We recommend

leaving the rear panel power switch active at all times, and placing the unit in Output Disable Mode

when finished listening. The vacuum tube is turned off during this mode and using this feature

while not listening will dramatically increase the tubes lifespan.

Trigger Input and

Output

The Stellar M1200 amplifier has a 5V -12V Trigger for remotely powering the unit on and off. It is

important to note that the trigger “out” is intended to loop through to a second power amplifier.

The Stellar amplifier does not generate a trigger signal. An input Trigger DC voltage is required.

Fault Protect Mode

The Stellar M1200 is designed to protect itself if it detects a dangerous signal surge or transient

that could damage the circuit. In these instances, the Stellar goes into Fault Protect Mode. If you

see the blue logo button flashing quickly and the amplifier turns itself off, then it has entered this

mode. This can happen if it is heavily overdriven. If this occurs remove power from the Stellar and

disconnect all inputs and outputs. Then, power the Stellar back on and verify that it powers on

normally. If this is the case then power off the Stellar and re-connect the speakers and sources.

Try playing music back at a low level at first. If after removing all connected equipment the Stellar

continues to enter Fault Protect Mode, please contact PS Audio.
