3. SETUP continued …

Microphone stand assembly:

Screw 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 receiver 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 Automatic mode. The program will guide you through the remaining steps and

at the end will load the correction data to your receiver. 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 receiver 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.

Quick Measure – speaker position helper:

If the subwoofer’s position is flexible you can try this before running ARC. Proceed as above but select

Manual mode instead of Automatic. Under “Tools” select Quick Measure then click on Connect, select

Subwoofer or any other speaker if its position is also flexible, and click Start. After approximately 10 sweeps

the graph will show a live update of the uncorrected measurement. Try different locations for the speaker

and leave it where the uncorrected graph is flattest. Once this is determined, run ARC normally.
