Exakt Optimsation

Introduction

Exakt Optimisation provides a listener focused view of room optimisation. This means that Exakt compatible products give the listener an opportunity to greatly improve the listening experience by providing the Exakt products with information about the listening environment. The software inside the Exakt products can then account for the listening environment and compenstate accordingly.

Overview

Konfig can optimise for the following acoustic phenomena:

Room Modes

Every room is different, and can therefore be optimised to sound as good as possible. You will need to use the TuneDem method to find the ideal location for your speakers.

Speaker Placement

In practice, the ideal TuneDem location for your speakers is rarely the practical location as well. Not to worry, optimisation will allow the ideal Tune Dem sound to be applied wherever your speakers are located.

High Frequency Response

Each room responds to high frequency (a.k.a. treble) differently. An empty room with marble walls will respond much differntly to a room with plasterboard walls and lots of soft furnishings. This stage allows you to optimise according to the high frequency response of your room.

Optimisation Process

Stage 1: TuneDem

1. Using the TuneDem method, deterimine the ideal speaker location for your room

2. Select your Exakt device in Konfig

3. Click on the Exakt Optimisation tab

Stage 2: Optimise for Room Modes

1. Click on the Room Modes optimisation tab.

2. Click on Change Dimensions.

3. Enter values for Room Dimensions, Listening Position, and Ideal TuneDem Speaker Position

a. All dimensions must be measured in meters.

b. Speaker measurements should be made from the outside front corner.

4. Click Optimise.

N.B. To remove any Room Mode optimistaion from your setup click Disable .

Stage 3: Optimise for Speaker Placement

1. Click on the Speaker Placement optimisation tab.

2. Click on Change Placement.

3. Enter values for Practical Speaker Position

a. All dimensions must be measured in meters.

b. Speaker measurements should be made from the outside front corner.

c. Ideal TuneDem Speaker Position mesaurements will be pre-populated from Stage 2, no need to change them

4. Click Optimise.

5. Click Disable to remove any Speaker Placement optimistaion from your setup.

Stage 4: Optimise for High Frequency Response

1. Click on the High Frequency Response optimisation tab. This stage is the equivalent of a treble shelf.

2. Enter frequency and gain values as required.

3. To disable any high frequency response, set the gain to 0.

Stage 5: Fine Tune Filter Parameters to Improve Audio Performance

1. Select the Room Modes optimisation tab

2. Each notch filter in the room optimisation graph is represented by a Room Mode (i.e. Room Mode 1, Room Mode 2, etc).

3. You can modify a notch filter by selecting it from the drop down box and entering new values.

4. Room mode optimisation is based on an idealised rectangular room, so some modifications to these values may be required

5. Speaker Placement optimisation is less prone to error, so modifying these values is not recommended

• Changing the Frequency value will shift the notch filter left or right along the x-axis.
• Changing the Gain value will change the height of the notch filter.
• Changing the Bandwidth value with change the width of the notch filter.

Known Restrictions

Room optimisation graphs will not be visible if you are running Konfig on Windows XP. This is becuase Konfig requires IE9 or higher and Windows XP is not compatible with IE9 or higher.
