= d / c where c is the speed of sound (about 344 m/s) . The PC260 processor also allows the delay to be set directly in meters or feet . Example: If the subwoofer is positioned 2 metres forward from the line of satellite units, the equation would work as follows: d = 2 m T = d / c = 2 / 344 = 0.006 s = 6 ms... -

Care must be taken when configuring these filters as they interact and can produce unexpected results . - Page 22 Low-shelf. A shelf filter has three parameters that determine the frequency response: frequency, gain and slope . In a Low-shelf filter the frequencies below its frequency setting can be boosted or cut . The extent of width of the filter’s transition band is the Slope, it can be fixed at 6 or 12dB or vary in this range .

. Use PG UP and PG DW buttons for scrolling between the two pages available . Each input and output of the PC260 has a dynamic processor hat can be configured as limiter or compressor and that provides a very complete set of parameters to control the sound dynamics . - Page 26 . The PC260 processors, like other loudspeaker processors, can protect the speaker from excessive heating using the OUTPUT LIMITER (though it is not possible to protect a speaker from every possible cause that occurs to damage it, such as over-excursion, very unnatural sound signals or an erroneous cross-over filter setting) .

Page 27: Spl Management
INSTALLATIONS . Using the SPLM the user can program changes in the settings of the audio system at a specified time in a specified day of the week . The PC260 has an internal clock that keeps the time also if the unit is turned off, so when an SPLM program is activated, the event programmed can be performed in real time . -
Page 28: Rta
The PC260 processor has a built in 1/3 octave Real Time Analyzer, which is a useful tool for measuring the acoustic response of the sound system in order to make the proper EQ adjustments . This RTA is not a precise measurement system such as dedicated computer software, but it can be used to get a general overview of the system's response in a not too much reverberant and noisy enviroment . -
