The mid and side mute buttons will let you mute mid or side so that you can listen to just
the sum or the diff.
Other MS functions:
When you don't use the insert switches 5 or 6, you can still make use of the
mid/side functionality. When the stereo/MS switch is set to MS, it passes through
the mid/side circuit. What you can do for instance, is making the side channel a bit
more wide or narrow by changing the gain on the side channel with the width knob.
You can also listen to just the mid or side channel by muting the corresponding
channel.
Insert 7 and 8:
Insert 7 and 8 are the same as insert 1 and 2, so 100% passive with swap functionality.
Outputs:
Outputs:
You can choose between the 2 outputs by selecting the corresponding button. It's also
possible to use both outputs at the same time, but keep in mind that this could cause some
impedance and so level changes.
Ins bypass:
When you engage 'ins bypass' all inserts will be bypassed. You will see that all lights on the
insert switches will go out, giving you extra visual feedback. Simply said, the input section
will go directly to the output.

Bypass offset Out 1:
Out 1 and 2 are passive output selectors with just relays, so no active circuit. So basically,
it's passing the signal from the inserts straight into the output. But when you push the 'out
1 bp offset', it will bypass all inserts and the active gain stage 'out 1 offset' comes active.
The monitor offset will allow you to change the bypass gain to make up for the processing
of the inserts. This way you can A/B between the analog processing and level-matched
bypassed signal. The gain range is set from -10dB to +10dB * done with a potmeter
instead of a stepped switch for a more precise adjustment. And since this is just an AB
function no recall is needed. Internally the gain range of the monitor trim can be calibrated
with 2 multiturn trimmers.
* note: the bypass gain range on earlier revisions was -2dB to +8dB

Active output gain:
The output is passive with just relays, but by pushing the 'active gain' button you will
enable the active gain stage which enables you to change the output gain to your liking. In
the mid/0 position, there is no gain applied though it passes the active gain circuit. You can

gain
* note: the gain range for the 0.25dB per step output gain is +/-2.75dB. It's also
possible to order the IM2.1s with a gain range toggle switch. That way you can
choose between 0.25 and 0.5dB per step.
