Step 2 Turn the level controls of the amplifier to their minimum positions.
Step 3 Choose music with high dynamic content that you like, that you are familiar with and will be most often used
in the system.
Step 4 Turn the unit up to its highest undistorted output level. If you lack test equipment, this point occurs between 3/4 to
full volume depending on the quality of your source unit. Listen for any audible distortion, if any distortion is au
dible, reduce the volume of the source unit until you have an undistorted output. Leave the volume control at this
position during your system tuning.
Step 5 While listening to your chosen dynamic music, turn up the level control corresponding to the midrange output until
you hear slight distortion and turn back the level control slightly for an undistorted output. Depending on your
system, the midrange and tweeter output may be on the same output channels.
Step 6 Turn up the level control corresponding to the tweeter output until you hear slight distortion and turn back the
level control slightly for an undistorted output. Depending on your system the midrange and tweeter output may be
on the same output channels.
Step 7 Fine tune the crossover setting and output level between the midrange and tweeters. Refer to the internal crossover
configuration section of this manual for detailed instructions.
Step 8 Repeat Steps 5-7 for the rear speakers. If you do not have rear speakers continue to Step 10.
Step 9 Set levels between the midrange and tweeters for optimum front/rear balance.
Step 10 Turn up the level control corresponding to the woofer output until you hear slight distortion and turn back the level
control slightly for an undistorted output.
Step 11 Fine tune the crossover setting and output levels between satellite speakers and the woofers. Refer to the internal
crossover configuration section of this manual for detailed instructions. If using an RGC-1, adjust the level to match
the output of the woofer to match the sonic requirements of the system.
Step 12 Enjoy your ass kickin' ORION sound system.
