Microphone stand assembly:
Screw the telescoping tube into its base and the microphone clip onto the tube. Position the clip vertically.
Connect the USB microphone cable to the microphone and slide the microphone into the clip.
Microphone positioning:
During measurement the microphone must point straight up. The microphone’s height is critical to proper
measurement and should be at ear level when seated.
Ideally, the front speakers’ high-frequency drivers should be at approximately the same height as the
listener’s ears but if they aren’t and the result sounds dull or bright, microphone height will have to be
adjusted and measurements repeated.
To adjust the length of the telescoping tube, first loosen its clamp by rotating it counterclockwise.
Five listening area positions are normally measured but this number can be increased up to ten. The first
must be at or just in front of the central seating position. This is also used to set Speaker Calibration levels.
Positions 2 and 3 should be symmetric to the left and the right of the center line, and the same applies to the
remaining positions. If your room has less than five seating positions, measurements must still be taken from
five positions at least 2 feet (70 cm) apart to ensure optimal sound.
Measurement:
• Connect the microphone and the processor to the computer.
• Set the microphone in the first position. Don’t stand near the microphone while sweep tones are
playing otherwise reflections from your body may cause bad measurements.
• Run Anthem Room Correction by selecting it from the Start Menu or double-clicking the Desktop
shortcut and select Standard mode. The program will guide you through the remaining steps and at
the end will load the correction data to your processor. The process takes about 20 minutes
depending on the number of measurements.
• Once the ARC program is finished, you can disconnect the computer. Turn on the processor and set
“Room EQ:” On/Off in the Source Setup menu according to each source. If you made measurements
for a Music configuration, assign Bass Manager accordingly.
• Save your settings in the Save / Load Settings menu. Note that changing the Sub crossover in the
Bass Management menu affects only Room EQ “Off” sources.
Advanced:
After a file is created in Standard mode, it can be opened in Advanced mode to change EQ range, crossover
points, and room gain. To do this, change Targets then click on Calculate, then Upload.
Since rooms and systems vary the only advice that Anthem technical support can provide without being
at your house to hear your system is to use the auto-detected settings. The alternative is trial and error.
To change the amount of room gain, the Force checkbox has to be checked for the manually entered change
in dB to take effect once clicking on Calculate. To restore the settings sensed by ARC, click on Auto Detect
and re-calculate. Clicking on Erase uploads flat parameters.
