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!
