4. What can I use the mixing board for?

a. The Avid S3 Mixing Board can be used for quickly controlling tracks within your
pro tools session. For example:
i. 1) Lower or raise track levels with the faders. 2) Automate levels (when
your track is set to modes such as "latch"). 3) Pan left/right. 4) Automate
left right panning (when your track is set to modes such as "latch"). 5)
Mute tracks. 5) Solo tracks
b. If you want to learn about the Avid S3 Mixer, there are tons of excellent youtube
videos explaining workflow integration, function, ect! We recommend you use
this tool to try something new!

5. How can I get rid of the HVAC noise?

a. In CDM 724, you may notice air conditioning noise in your recordings. There are
a few ways to approach this problem:
i. Turn of the AC in the live room (push the scroll wheel to the right)
i. Utilize noise reduction plug-ins after recording
ii. Directly insert a noise reduction plug in to your recording track
- There will always be numerous controllable and uncontrollable factors contributing to
unwanted background noise. We recommend you reserve CDM 600A and compare the
quality of recordings each studio can provide. Both rooms have pros and cons, so it is
best to decide your own preferred studio!
