Adjusting Sound Of The System - Orion HCCA HCCA25001 Owner's Manual

slight distortion and turn the level control back slightly for an
undistorted output. Depending on your system, the midrange and
tweeter output may be on the same output channels.
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.
7. Fine-tune the output level between midrange and tweeters.
Refer to the Internal Crossover Configuration section of this
manual for detailed instructions.
8. Repeat Steps 5-7 for the rear speakers. If you do not have rear
speakers continue to Step 10.
9. Set levels between the front and rear midrange and tweeters for
optimum front/rear balance.
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.
11. Fine-tune the output level between satellite speakers and the
woofers. Refer to the Internal Crossover Configuration section
of this manual for detailed instructions. If using an RGC2, adjust
the level to the output of the woofer to match the sonic require-
ments of the system.
12. Enjoy your awesome Orion sound system.

Adjusting the Sound of the System (Advanced)
This method requires using a digital multimeter (DMM) and is more
accurate than adjusting by ear. Find the optimum AC voltage output
of your amplifier by using Ohm's law. For example: if you have a
200 watt (rms) mono amplifier that you are going to run at 2 ohms.
Multiply the power by the resistance which equals 400, the square
root of 400 is 20. According to the calculation, the amplifier needs to
read 20 volts AC for optimum power output.
E = P x R 200 watts x 2 ohms = 400
E = AC Voltage that will be measured across speaker outputs. P =
Power in Watts, R = Total Resistance of a speaker(s) hooked to one
channel.
The following steps detail the process.
1. Using Ohm's law calculate the amplifiers target voltage output
(as in the afore shown example).
2. Obtain a test tone CD with 50Hz tone for Subwoofer amplifiers.
Make sure the sin-waves has a 0db reference level at 50Hz.
3. Disconnect all the speakers from the system.
4. Turn off all source unit processing, Loudness, EQ's, Intelli-Q and
set all adjustments to flat (Bass/Treble controls).
5. Turn amplifier gain control all the way down.
6. Adjust the source unit volume to about ¾ to insure a non clipped
signal out of the unit.
7. Play the 50Hz sine-wave.
8. Set DMM to AC voltage. Connect the black (negative) probe to
E = 20V AC
