Location
Once your Stellar Amp is unpacked, you’ll need to find a convenient place to set it. We recommend floor
mounting on a platform or shelf mounting as close to the speakers as possible. If the source equipment
(preamp or DAC) is far away from the Stellar, it is recommended to use balanced interconnects if
possible. Placement of the Stellar is important from several aspects: proper cooling and best audio
practices. Make certain wherever you place the Stellar there is adequate ventilation space above and
below the unit.
Once you have chosen the location for the Stellar you can use the supplied AC power cable to connect
it to the AC power or you can use an aftermarket power cord. Power cords make a difference and we
do not recommend using the supplied power cord for critical listening or long term use. We strongly
recommend the use of a PS Audio PerfectWave® Power AC cable or any excellent aftermarket power
cable for best results as it is always preferable to feed your equipment with the best power cables
possible. Choosing an excellent power cable will make a significant performance improvement over
the stock power cable.
Power Cables
Country Specific
AC Voltages
The Stellar, as with all PS Audio products, is country specific to its incoming AC voltage. This means
the units can only be operated at its preset voltages, such as 230 for most of Europe and Asia, 100
volts for Japan and 120 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
Connecting cables matter. 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.
Connect the
Speaker Cables
With the amplifier firmly seated where you have selected, it is time to connect the speaker cables.
The Stellar S300 and M700 use custom machined connectors. These connectors were specially
engineered to match the performance specifications of the Stellar Amp.
The connectors can accept spade, banana or wire connections. There are two sets for each channel
on the S300 and two sets for the singly mono channel on the M700. Most systems will use only
one set of the binding posts to connect the speaker cable. Use only the finest speaker cables and
connectors.
Note that you should never connect speaker cables while the amp is on. If one speaker lead is
connected (+ or -) and the other lead brushes up against the chassis, there is the potential to present
the speaker with 25VDC . This voltage has the potential to damage a driver (usually the woofer) in a
speaker.
Black Terminal is
Not Ground
Its important to note that the Stellar Amplifier is a fully balanced BTL amplifier. As such the Black
terminal is not ground. If connecting the Stellar to a Rel Acoustics Subwoofer its important to consult
the manufacturer’s service documentation to ensure the Stellar is appropriate for the subwoofer.
