*Continuous duty cycle across the audio band. Dependingon impedance, time may be thermally limited to several minutes. Congratulations on your purchase of this EXCELINEAR POWER AMPLIFIER. We are confident that this amplifier is capable of driving any known loudspeaker load, with sufficient power reserves to suit any home listening situa- tion. Furthermore, its refined circuitry will deliver that power with an accuracy that is sure to satisfy the most demanding of audiophiles. INSTALLATION The gloss black insert on the faceplate of your new Hafler Equipment has been packaged with a removable protec- tive coating. Please peel off this coating following installa- tion. When cleaning the faceplate, we advise a soft cotton cloth with a non-abrasive cleaner that is safe for Lexan and painted surfaces. DO NOT use paper towels or any coarse materials to clean the faceplate as these materials may scratch the insert. Ventilation Adequate air flow is important to the continuing reliability of any power amplifier. The XL-600 uses a quiet, con- tinuously variable speed fan to cool the entire chassis Cool air must circulate freely into the side vents and out the rear vent. Allow at least one inch on each side, and at least three inches to the rear for unimpeded flow. AC Line Connections and Switching NOTE: BE SURE YOUR AMPLIFIER IS WIRED FOR YOUR LOCAL LINE (MAINS) VOLTAGE BEFORE CON- NECTING AC POWER! 2

If the pilot lamp does not glow when the amplifier is turned on, and it is not due to an excessive temperature condition, then either the internal 15 ampere line fuse is blown, or the circuit breaker or fuse supplying the AC power has inter- rupted power. If no sound is heard once the relay engages and an input signal is applied, check all input and output connections, as well as the back panel speaker protection fuses. In addition to the internal 15 ampere line fuse, there are four 10 amp rail fuses, None of these internal fuses are intended to be user replaceable, and a blown condition usually indicates a need for professional service.
