Monitor and Cue Controllers
308
Note: Since ULN-2s have dedicated a stereo Monitor route which goes to both the front panel
headphone jack and stereo TRS monitor outs on the back panel, only a default Monitor Controller
output is established. The default Cue Controller for a new ULN-2 root box is unconfigured.
Freeing up Monitor Controller outputs
If your workflow does not require the best-sounding Monitor Controller on the planet, highlight the Monitor
output you want to remove, then select “Delete Current Monitor Output” from the menu bar “Monitor”
menu.

This will immediately remove the MC output and make the outputs available in the output routing dialogs.
Editorial note for LIO-8 and ULN-8 owners: Before re-purposing the Monitor outputs, you owe
it to yourself to at least audition the MIOConsole3d Monitor Controller one time.
Just connect the analog 1 and 2 outputs to your speaker amplifiers and listen to a few familiar
songs. If you use eq or DSP acoustic correction, first try monitoring with the room correction
hard-bypassed (LIO-8/ULN-8 connected direct to the amps), then again with your processing
in-circuit.
Monitor Controller “0.0” reference
The Monitor Controller determines the monitor gain headroom above “0.0” in the MC volume control
by how much gain it can apply before a full scale digital signal would clip at the converter. The available
headroom varies per the analog stages of each 3d device model.
On the ULN-8 and LIO-8, there is an analog domain gain control block after the converter that supports
30 dB of gain above monitor level.
When the MC determines that it has access to those gain blocks on all of the output channels of the output
path, it knows that it can add up to 30 dB of gain in the analog domain without introducing any digital
clipping. So that causes the zero point of the monitor knob to allow you to add 30 dB of gain. When you
add the -10 trim, that moves the zero point down 10 dB and gives you 40 dB of gain above zero that can
be done in the analog domain.
When one or more of the channels in the output path does not have the analog domain gain stage available,
then the MC gain is done in the digital domain and the maximum gain that can be applied in the digital
domain without running the danger of having a digital clip is 0 dB. So the maximum gain on the MC in
that case is 0 dB and when you add the -10 trim, that moves the zero point 10 dB down and gives you
10 dB of gain before digital clip.
This will be the case when you have the output Destination set to “None”, to a digital output or to a 2882
or ULN-2 analog out.
