Introduction The X5 five channel amplifier embodies the design technology and refinements of the larger “X” series amplifiers including extensions of the patented Supersymmetry circuit. The Supersymmetry circuit topology was granted a U.S. patent in 1994, and is the result of 19 years of effort by Nelson Pass. The amplifier uses highly matched components in a classically simple balanced Class A circuit.
The X Series amplifiers have the tremendous dynamic range (>150 dB) to do justice to the 24 bit recordings of the 21st Century. The simple but powerful circuitry moves easily from total silence to explosive transient and back to silence without a trace. It’s a spooky experience. So relax and enjoy your amplifier. Call us if you ever have a problem or question. Thank you for buying our product. Setup You can position the amplifier anywhere you want, but it requires ventilation.
single blue LED lit. No speaker connected yet. You can go ahead and connect the source and speakers. The amplifier can be driven single-end or balanced, if driving the amplifier single-ended leave the supplied jumpers in place (between pins 1 & 3 on the XLR). Now that the source component is connected, make sure there is no signal coming from it, probably by turning the volume all the way down. With the speakers connected, push the front panel button to activate the amplifier. The “Power” LED will come on.
of about 9 volts to 15 volts. This switching will override the front panel button, so if you want the button to operate, leave the rear connection open. So much for essential information. Speaker Interface The X5 is optimized for loads nominally rated at 4 ohms and above. You can run the amplifiers into a lower nominal impedance without difficulty, and we are not aware of a speaker on the market that presents unusual difficulty with these amplifiers.
Fortunately the amplifier is not sensitive to the capacitive/inductive character of some of the specialty speaker cables, so feel free to experiment. We have found that about 90 per cent of bad sounding cables are really bad connections, and we recommend that special attention be paid to cleanliness of contact surfaces and tight fit. Speaker cables should be firmly tightened down at the speaker output terminals, but do not use a wrench. They will not withstand 100 foot-lbs of torque.
