Connect the Ergo audio interface unit to your computer via the FireWire cable.
Connect speaker cables to the "Speaker Out" jacks on the back of the Ergo audio interface. Connect the other ends of these speaker cables to your speakers. If you have passive speakers, connect the cables to an amplifier and then connect the amplifier to the speakers with a speaker wire.
Connect an XLR cable to the "Cal Mic" (calibration microphone) input jack on the Ergo audio interface to help Ergo detect the acoustic properties of the room.
Connect the other end of the cable to a microphone. Place the microphone on an adjustable microphone stand.
Launch the Ergo program by double-clicking the desktop icon.
Select "EQ" and "Room Wizard."
Adjust the volume dial on the audio interface when prompted. An on-screen message will appear to tell you the volume is "Too Quiet, "OK" or "Too Loud."
Adjust the microphone stand when you see the message "Place microphone in focus position." The focus position is the position of your head, when your are mixing music. To determine this position, sit at the mixing desk.
Hit "Enter" when ready. This makes Ergo emit a multitone sound. Ergo is configured to calculate acoustic deficiencies in the room based on how the tones reflect back into the microphone. Ergo is configured to analyze the sound of the tone against a set of default parameters, the values of which represent the ideal acoustic environment.
Move the microphone 20 inches back and hit "Enter" again. Repeat this process three or four times until the wizard indicates you have at least a 90-percent complete room analysis.
Click "Yes" when you see the message "Measurement Done: Store Measurement?"
Turn off the "Calibrate" button on the rear of Ergo. From now on, Ergo will adjust the frequencies in the audio as it leaves the output device. This gives you an accurate representation of how the audio will sound in an acoustically perfect environment, enabling you to make smarter and more accurate mix tweaks and equalization choices.
