GEQ
The Si EXPRESSION features a 28 band Graphic EQ on every mix, matrix and main master; having
a GEQ on every bus means there is no need to ‘patch’ the GEQ, just enable it when required with
no risk of running out of DSP.
The GEQ function is available whenever an audio mix master is SELected, at all other times the
GEQ keys will have no function.
With a mix master SELected press either the GEQ HI or LO keys to open the GEQ across the 14
faders immediately left of the FADER BANK keys; the ON key will be lit red of any GEQ band not
at 0dB, press the lit key to return that band gain to 0dB.
Toggle between GEQ HI & LO with the appropriate key. The frequency bands for HI and LO are
shown on the polycarbonate overlay at the top of each fader; the scale on the left hand side of
the fader slot indicates the dB of cut or boost applied and there is the ‘Function Focus’ display
on the LCD displaying a view of all the GEQ faders and the gain of the band being moved.
To manually exit the GEQ press the lit GEQ HI/LO key, Si EXPRESSION will automatically exit GEQ
mode if changing / activating a mix follow key, SELecting a fader that is not an audio mix master,
changing layers or re-SELecting the bus to which the GEQ is currently open.
Press and hold either of the GEQ keys for 4 seconds to toggle the GEQ in/out of ‘bypass’; while
in bypass the ‘inactive’ GEQ LO/HI band key will be lit orange.
NOTE: When not in a mix follow mode it is possible to swap the GEQ between mix masters
on the current layer by SELecting another master; any fader slots not used by the GEQ will
remain showing the function and name associated with that fader. SELect assignments on
the GEQ bands will remain as they were before the GEQ were opened.
NOTE: To reset all bands of the active GEQ press CLR together with either of the GEQ keys.
