- Page 2 Driving into a short will not convey any additional power. These are not design oversights or flaws in the XA60, but rather a condition of the very highly biased Class A operation. However; as an interesting point of reference, 60 watts driving a 87dB/1W/1m speaker will deliver well in excess of 100 dB XA60 Owner’s Manual...
- Page 3 300 watts, the equivalent of an incandescent reading light. At idle most of that energy is dissipated across the heat sinks, so the heat generated by each XA60 is equivalent to an incandescent reading light. To dissipate this heat the product should have about 6 inches clearance to the top and sides for adequate air circulation.
- Page 4 We have provided a standard IEC power cord that fits into the standard 15 amp IEC receptacle at the rear of the amplifier chassis. Two XA60’s may be run on a single 15-amp circuit in conjunction with other audio components. This amplifier is equipped for operation with an earth ground provided by the users AC outlet.
- Page 5 Make sure you are in standby mode to protect your speakers from transients. The prudent installer will unplug the XA60’s power cord from the mains while attaching speaker cables. To avoid the possibility of short circuits always connect speaker cables to the speakers prior to connecting to the amplifier.
- Page 6 People are interested in how long it takes for these amplifiers to break in. Depending on the resolution of the rest of your audio chain, you may or may not notice any break in of the XA60 beyond the first 50 hours of operation. You will likely notice the difference in...
- Page 7 “on” position. Speaker Interface The XA60 is optimized for 8-ohm speaker loads. Having said that; we are not aware of any speaker on the market that presents an unusual or difficult load for these amplifiers.
- Page 8 This very conservative rating contributes to exceptional voltage regulation figures and low noise figures at the loudspeaker. The XA60 has a significant number of power supply filter capacitors. These caps are used to create the unregulated output stage rails, RC filtering is used to passively remove ripple from the supply rails.

All other servicing must be referred to qualified service personnel. XA60 Owner’s Manual...
- Page 12 It was named Super- symmetry™ as an homage to particle physics, but it is popularly known as the X circuit. Balanced amplifiers improve performance by differentially rejecting dis- tortion and noise. To the extent that distortion and noise are identical, XA60 Owner’s Manual...
