Tannoy 66D, 8D owner manual Guide to Setting the Equalisation

Hi-Mid Shelf Boost/Cut: a shelving filter between 1kHz and 3KHz can be set to +2, +1dB, flat, -1dB, -2dB, to take account of room characteristics and personal preference. Editing news broadcast material is often easier with an increased output in this band. Figure 6 shows the range of adjustment in this area controlled by DIP switches 11 to 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.

High Frequency Shelf Boost/Cut: a shelving filter between 5kHz and 50kHz can be set to +3dB, +2dB; +1dB, flat anechoic, -1dB, -2dB, -3dB to take account of RT60 decay times for the environment within this band and to allow a degree of personal preference. Figure 7 shows the range available diagramatically.

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.
