SPECIFICATIONS POWER RATING: Less than 0.08% THD at any power level up to 305 watts per channel into 8 ohms at any frequency from 20 - 20 kHz with both channels driven. CONTINUOUS POWER OUTPUT: 450 watts per channel into 4 ohms at less than 0.1% THD, 20 - 20 kHz. 900 watts in mono into 8 ohms at less than 0.1% THD, 20 - 20 kHz. -
Page 3: Installation
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. -
Page 4: Input Connections
The XL-600 is normally wired for use on 120 Volt 60 Hz power lines. If your line (mains) voltage is different, you will require the optional export multi-voltage transformer, which accommodates voltages from 100 to 240 VAC, at 50-60 Hz. -
Page 5: Output Connections
Output Connections To preserve the high damping factor of the XL-600, and to minimize power loss, the use of at least wire is recommended, especially for speakers of less than 8 ohms impedance, or for wire runs of 15 feet or more. -
Page 6: Operation
The red pilot bar will light a few seconds before operation is auto- matically restored if the XL-600 has cooled down and the power switch is left on. check for inadequate ventilation, continued excessive input signal, or a severely reduced load impedance. -
Page 7: Initial System Check Out
The fuse holders on the back panel provide a measure of protection against excessive power output to the speakers. They are not intended to protect the amplifier. The XL-600 is supplied with 5 ampere fast blow fuses installed. This value will afford minimal protection for most speakers. A spare pair of 10 ampere fast blow fuses has been included, for testing purposes, or high power applications. - Page 8 It will already be exceedingly low on the XL-600 as you receive it because each amplifier chan- nel has been factory adjusted using a typical loudspeaker load. But when the XL-600 is connected to your own speakers, careful readjustment by a technician may yield some slight improvement.

Page 9: Performing The Adjustments
A pair of headphones which have a high degree of isolation from outside sounds may simplify your test listening, but are not essential. If a very sensitive meter is available, it can replace the listening requirement, but your ears are better than conventional meters. - Page 10 The test procedure is as follows: 1. First use the right channel of the XL-600 as the driving amplifier and the left channel as the test amplifier. Turn off the amplifier each time before making any change in connections, and before removing the cover.

DC voltage present at the output. Minor turn-on thumps or clicks are normal and should be ignored. Since the XL-600 is direct coupled, any DC present at the input to the amplifier will be passed onto the output. - Page 12 The Hafler XL-600 is warranted for 3 years from date of purchase, including parts, labor, and return shipping costs from the factory to the owner within the Continental USA.
