Power Input

ERGO’s power input accepts a 12VDC power supply capable of delivering a minimum of 1 amp. If you intend to keep ERGO hooked up to the FireWire port on your computer (6-pin), you do not need to use the external power supply, as ERGO is designed to use the power coming in via the 6-pin FireWire port.

While ERGO can use a 6-pin FireWire port’s power for itself, many times this will be a bit “noisy.” If you find this to be true in your case and you think ERGO is not providing the best sonic quality that it can, go back to using the external power supply. Keep in mind, that you will always need to plug ERGO into the external power supply when using a mini 4-pin FireWire cable since it does not provide power like its 6-pin counterpart.

FireWire ports

These 2 ports allow input and daisy chaining of FireWire signals. One of these ports must be used while ERGO is measuring and calibrating your room.

Note Usually, the FireWire port is only used when ERGO is running its room analysis. After the analysis is complete, you can unplug the FireWire interface and still use ERGO in Standalone mode using the Line or SPDIF Inputs.

SPDIF IN

It receives digital audio data.

Cal Mic Input

This jack is used to connect the ERGO measurement microphone. It is only used during the calibration process.

Note It is recommended that you use the mic supplied with ERGO for room calibration. ERGO supplies a 15V phantom power source to its microphone, and using other mics for calibration may result in poor room analysis and improper correction filters.

Line Inputs (L & R)

These balanced/unbalanced audio inputs are used either as inputs from your existing audio interface or as recording inputs from a mixer. You may want to use the Analog Inputs for one of the following reasons:
