KRK ERGO manual Setting up Ergo and your Mixing Environment

3. Setting up ERGO and your Mixing Environment

Using Analog (L & R) and Digital (SPDIF) Inputs

Here are a few tips to keep in mind when dealing with Analog and Digital Inputs with ERGO. When using ERGO as a soundcard connected via FireWire to your computer, the FireWire audio stream is automatically selected as the input source.

If you are in Standalone mode (no FireWire connected) and using either the SPDIF Input or the Analog Inputs, ERGO selects the audio source as follows:

1.If ERGO detects a SPDIF clock, it automatically selects the SPDIF Input as its source.

•If ERGO has detected a SPDIF clock, but you want to use the Analog Inputs, then you must use ERGO’s control panel to select the Analog Inputs.

•If ERGO has detected a SPDIF clock, but the SPDIF Input is not working, then ERGO was started in Analog mode. Use the ERGO Control Panel to select the SPDIF Input.

•If the SPDIF Input is not working, ERGO is probably not locking its clock to a SPDIF clock. Check your cables and the audio output selection in your DAW application.

2.If ERGO does not detect a SPDIF clock, it automatically selects the Analog Inputs as its source.

3.4 Test Signal and Measuring Techniques

To get the necessary Room Knowledge, ERGO relies on a new way of measuring the room. Using traditional test signals such as pink noise, normally means a trade-off between signal-to- noise ratio (SNR) and frequency resolution. Long analysis windows lead to high frequency resolution but poor SNR due to the low number of averages. But using multiple pure tones means long analysis windows (5.5 seconds for low frequency test signal) leading to both high frequency resolution (0.2 Hz) AND an excellent SNR due to very narrow analysis bandwidth

in the frequency domain, something which is almost insensitive to normal broadband background noise.

ERGO generates energy at the very same frequencies where the analysis takes place, that is energy and processing is not wasted by measuring the spaces in between the analysis frequencies. Why go to all of this trouble? Because traditional 1/3 octave measurement and correction (three frequencies for each doubling of frequency) is not sufficient for room correction. Room correction needs great analysis and powerful processing, both of which ERGO delivers.

3.5ERGO with RoomPerfect™ is the Solution

In our quest for the best possible components to power ERGO’s Room Correction technology, KRK licensed RoomPerfect™ from Lyngdorf Audio. Why Lyngdorf? Because they are the best, and they solved the problem with getting 3 dimensional Room Knowledge in a very unique way. By combining global measurements (room positions) with measurements at the listening position, up to 8 corrected listening positions can be calculated.

The RoomPerfect™ system combines information about the listening position with information about the energy transport into the sound-field in a completely new and innovative way. The measurement at the listening position holds information about the listener’s access to the sound-field while the room positions hold information about the 3 dimensional sound-field in the entire listening room. And so, perfect sound is rendered, regardless of your listening room, speaker position and listening position. In fact, the vast amount of information gathered about the sound-field allows you to enjoy the benefits of room correction in any spot in the room.

You will see, and hear, a system with all required knowledge and operation already embedded in it, a “smart” system.
