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.

IM2.1
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

IM2.1s
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
change the gain in 23x0.5dB steps from +/-5.5dB* with stepped switches.

* 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.

Rearpanel:

Inputs:

The IM2.1(s) has two balanced inputs. Both inputs consist of gold-plated Neutrik XLR’s.

Inserts:

The IM2.1(s) has 8 balanced inserts connected on the back with industry standard Tascam
DB25 analog connections. Each connector holds 2 inserts corresponding with the frontpanel
numbering.
