1. Introduction
1.3How does ERGO work?
ERGO takes a stereo audio stream from the analog or digital (SPDIF or FireWire) domain and processes it though a 96 kHz room correction algorithm. All incoming analog audio is sampled at 96 kHz, while incoming digital audio is sample rate converted up to 96 kHz for processing. If incoming audio comes in over FireWire, the processed audio is converted to reflect the output frequency of the ASIO driver, up to 192 kHz. In Digital Input mode, the output frequency and the audio going to your monitors is going through digital to analog converters fixed at 96 kHz sample rates.
ERGO’s architecture provides the best audio quality while maintaining compatibility with existing systems. In fact, the audio converters used in ERGO are the same as those found in

1.4Input Modes
ERGO has 3 Input modes (Figure 1);
•FireWire Audio Input
•Analog Input
•Digital Input
1.4.1FireWire Audio Input
In this mode, ERGO looks like an ASIO audio device under Windows, or as a CoreAudio device on a Mac. To ensure your monitor or mastering mixes will be correctly compensated for your listening environment, it is recommended that you select ERGO as your DAW main Left/Right outputs or output bus. At the moment, Windows supports a single ASIO device, so you must use ERGO as your only audio interface. To use your existing multichannel audio interface with ERGO, just run ERGO in Analog or SPDIF Input modes.
1.4.2Analog Input
The Analog Input mode is the easiest way to implement ERGO into your existing listening environment. If you already have your DAW set up just the way you like it, and like your current audio hardware, just plug the main Left/Right outputs of your DAW hardware into the ¼” balanced inputs on ERGO.

1.4.3Digital Input
This is similar to the Analog Input mode, except that a digital SPDIF Input is used. The SPDIF on ERGO accepts any input signal from 44.1 kHz up to 96 kHz. The analog speaker outputs in this mode will be fixed at a 96 kHz sample rate.
