Graphic Equaliser Behaviour
Each input of the 5 Series
5 Series 5 Series 5 Series units has a 28 band graphic equaliser, allowing “traditional” manipulation of the frequency
response in a manner immediately familiar and accessible to all users. The behaviour of the equaliser may be adjusted to
produce an effect similar to either the GQ600, or a “Special” type of response. Both types will be explained in this
section, and what primarily makes them sound as they do. XTA’s AudioCore software has been used in the following
screenshots.
The “GQ600” behaviour
The GQ600 behaviour is designed to offer the “best of both worlds” in terms of corrective control and creative control.
This is achieved by manipulation of the bandwidth of the filters, depending on the amount of cut or boost being applied.
At low levels of cut/boost (where it would be safe to assume the changes to the EQ are mainly for creative use) the
bandwidth is wider, so the changes to the overall response are gentler.
As can be seen by this example, the
500Hz band has been boosted by 2dB,
and the bandwidth that has been
affected is quite wide (there is still
appreciable activity an octave on either
side of 500Hz – 250Hz and 1kHz).
Looking at the response when the
band is boosted to +8dB reveals a
narrowing of the affected range of
frequencies.
The narrowing of the bandwidth
allows more precise control when
trying to pinpoint and correct
anomalies in the response.
