Installation

Considerations Location

Once your new Stellar M1200 Amplifier is unpacked, you will need to find a convenient place

to set it. A good location for the Stellar M1200 Amplifier is in a cabinet or on a shelf at an easily

accessible height. The Stellar M1200 Amplifier and the Stellar Gain Cell DAC were designed to

stack on top of each other if they are not placed on separate shelves. Do not remove the feet.

Mounting

The Stellar M1200 should be placed with consideration of providing air circulation to the unit. If

you wish to install the Stellar M1200 into your component rack, the purchase of an aftermarket,

custom-designed shelf may be necessary.

Plugging In e

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.

Stellar M1200 Amplier

Getting Started

Country Specic

AC Voltages The Stellar M1200 Amplifier, as with most PS Audio products, is country specific to its incoming

AC voltage. This means the unit can only be operated at its preset voltage, such as 230 volts

for most of Europe and Asia, 100 volts for Japan, and 120 volts for the US and other similar

countries. Immediate damage can occur if you try and power the Stellar with a voltage it was not

designed to operate on.

Cables Matter The cables that you use can have a dramatic influence on the sound of your system. Carefully

choose your speaker cables and connecting cables to the equipment. Our preference for input

cables is balanced, XLR type, but well-built single ended RCA cables are fine as well. Speaker

cables can make or break the performance of an amplifier and great care should be taken in using

only the best match for your loudspeakers and Stellar amplifier.

How to Install and

Remove Vacuum

Tubes

Items Needed:

• #2 Phillips-head screwdriver

• 12AU7 Vacuum Tube

1. Remove the tube access plate on the rear of the M1200 using a Phillips-head screw

driver.

2. Orient the tube so that it aligns with the keyed area on the tube socket.

3. Insert the tube into the tube socket until the glass is seated up to the ceramic of the tube

socket.

4. Screw the tube access plate back into place.

1. Remove the tube access plate on the rear of the M1200 using a Phillips-head screw

driver.

2. While gently pulling, roll the tube in a circular motion until it frees itself from the socket.

If you are having difficulty reaching the tube with your hands, we offer a specialized tube puller on

our website.

Installing the Tubes

Removing the Tubes

Tube Puller

Vaccuum Tube

Maintenance The M1200 amplifiers come with their vacuum tubes installed. Changing the tubes is easy. The

process is as simple as removing the rear vacuum tube access plate and installing the new tube.

Changing to a different 12AU7 tube can result in a sound that is more to one’s preference and

allows the opportunity to optimize the system’s synergy. If it’s desired to try a different tube,

obtaining good quality and low noise/microphonic tubes are the customers responsibility. PS

Audio will not be held accountable for noises or poor sound quality due to any tube other than

ones shipped from the PS Audio factory.

Connect the Speaker

Cable With the amplifier firmly seated where you have selected, it is time to connect the speaker

cables. The Stellar M1200 uses custom machined connectors. These connectors were specially

engineered to match the performance specifications of the Stellar amplifiers. The connectors

can accept spade, banana or wire connections. There are two sets for the mono channel on the

M1200. Most systems will use only one set of the binding posts to connect the speaker cable.

Black Terminal is not

Ground It’s important to note that the Stellar M1200 is a fully balanced bridge tied load (BTL) amplifier. As

with all BTL amplifiers, the black terminal is not ground. If connecting the Stellar to a Rel Acoustics

Subwoofer it’s important to consult the manufacturer’s service documentation to ensure the

Stellar is appropriate for the subwoofer. The ground lug on the rear of the amplifier can be used to

ground the subwoofer in these applications.

Bi-wire Some may wish to Bi-wire their speakers to the Stellar. This practice involves using one shotgun

configured cable or two separate cables. In either case, connect one cable to one set of binding

posts and the other to the second set. On the loudspeaker side, one pair of cables goes to the

tweeter binding posts, the remaining set to the woofer section.

Plug in Connecting

Cables The Stellar M1200 Amplifier accepts either single ended RCA or balanced XLR connections to the

preamplifier or DAC feeding it. We highly recommend the use of balanced connections, especially

for longer runs.

Getting Started

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.
