An A/V 80Hz high pass filter switch provides instant conversion to 5.1 and higher order systems where a separate subwoofer
below 80Hz is required. Filter characteristics are according to the international standards for this setup. This response is also
shown diagramatically in Figure 1.
Listening to well recorded male or female spoken word or vocals at the normal listening position is a good way to check and
optimise the available settings. Difficult environments and variable listening distances produce varying degrees of boost from
the flat position in the 50Hz to 800Hz area. Graphical representations of the responses available by setting the switches are
shown below. The linear or flat response positions for the DIP switches are always clearly shown in the diagrams below and
also on the rear panel of the speaker.
The Tannoy ActivAssist
™
software package is available to help with the DIP switch settings. Using a standard laptop with the
microphone and cables supplied in the pack, the performance of the speaker in a particular environment can be assessed and
a recommended set of switches set up.
