Getting Started ® Installation Considerations Stellar M1200 Amplifier 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.
Getting Started Stellar M1200 Amplifier ® 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.
Getting Started ® Stellar M1200 Amplifier Connect the Speaker With the amplifier firmly seated where you have selected, it is time to connect the speaker Cable 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.
Getting Started ® Stellar M1200 Amplifier 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.
Getting Started ® Stellar M1200 Amplifier Common Questions Question: Does it matter what set of binding posts I use to connect my speakers? From Customers Answer: The M1200 has 2 sets of output binding posts. These are meant for Bi-wiring and the output signal is the same on both sets of outputs. It does not matter which set is used. Question: Can I stack M1200s? Can I stack M1200s with a GCD? Answer: It is completely fine to stack M1200s and it is also acceptable to stack them with a GCD.
Getting Started ® Stellar M1200 Amplifier Debug Of Common Issue: Issues Hum or low frequency buzz coming from the speakers Recommendation: Unplug the input cables that are connected to the M1200s. If sound goes away a ground loop is present. Move to balanced cables if possible. Plug all equipment into the same receptacle. Debug using other methods from ground loop detection.
