EQ 4
In position 6 (Ext) the external side-chain insert is activated. Via insert send and
insert return, an external stereo equalizer can be integrated into the side-chain signal.
Individual filter curves can be created to focus the response of the compression to
certain frequency ranges.
In Link mode, only the side-chain insert of the right channel is active.
Tip:
You can also use a mono equalizer with two parallel outputs in the side-chain insert. The
input signal then has to be received from the send of the right channel – not from the left
channel!
If no external equalizer is connected to the side-chain insert or if the send and return of
the side-chain insert are not bridged with a cable, the audio signal in the IRON will be
interrupted when the switch position (Ext) is selected.
