Hochm itten: der Kuhschwanzfilter regelt den Bereich von 1 – 3kHz um +/-2dB in 1dB-Schritten zur Anpassung an Raumakustik
und persoenliche Hoergewohnheiten. Rundfunkmaterial laesst sich bei Anhebung dieses Bereichs z.B. angenehmer editieren.
Abb. 6 zeigt die Regelmoeglichkeiten mit den DIP-Schaltern 11 -14.

5.0: A GUIDE TO SETTING THE EQUALISATION
Assess the monitoring conditions and consider these 4 main factors:
1. The environment: free space (4pi), half space (2pi), quarter space (pi) and in the extreme, a "Difficult Space" (pi/2)
2. The distance from the speakers: far field (2 to 3m), mid field (1 to 2m), near field (0.5 to1m) or close field (less than 0.5m)
3. The room: absorbent or reflective surfaces, estimate the RT 60 decay time above 1kHz
4. The nature of the source material: prolonged sessions working on editing bright or forward material can produce fatigue.
Free Space (4Pi): An example of free space conditions would be with the speakers mounted on tall (0.5m to 1.2m) speaker
stands well away from the wall at one end of a room and with the listener 2 to 3 meters away. Under these conditions set all

the DIP switches to the 'flat anechoic' position. This then provides a high quality high fidelity installation operating in good
acoustically treated environments.

Half Space (2Pi): An example of half space would be with speakers against a wall mounted on stands as above, or on the
meter bridge with the console in the centre of a room. Follow the DIP settings in the diagram below for half space (Pi/2) and
adjust for the listening distance accordingly. Adjust the LF-Q settings to balance the system.
