MIDIMAN OMNI O
Owner's Manual

1/4� TRS connection. This now processed signal is what is sent to the Delta H/W Ins, which are the record inputs to the Delta card. This type of insertion point is most often used for dynamics processors such as compressors or expanders (noise gates), or for other outboard gear such as an equalizer (EQ). Since an insert is often found on a patchbay, using an insert to add a processor to the signal flow is sometimes called �patching-in.� We will refer to these patch points as �insert out� and �insert in.� Use the left side of the cable for the Omni �insert out� point. This will then plug into the input of your outboard device. The right side of the cable is your �insert in�. Plug it into the output of your outboard device. This piece of outboard gear is now part of the signal flow, and the recorded signal will include this processing. Your insert cable will either be marked �left� and �right,� or designate the right side of the stereo signal by being colored or marked in red. Outboard gear such as dynamics processors will have controls and settings that will vary from one device to another. Therefore, we can only speak in general terms and suggest a way to go about adjusting these gain stages. With the processing controls set to a neutral setting, or bypassed: 1. If there is an output setting on the outboard device, set it to 0dB, or unity gain. This way, the device is not adding or attenuating the original signal. Set the input level on the device, trying to match the level of the signal (according to how it shows up in the Delta mixer or the music software). Adjust processing controls, such as threshold and ratio, toward the desired effect. Adjust the output level on the outboard device as needed, finally finetuning all gain stage levels.

See section 10.6 for �Adding Effects.� The Omni Inserts can also be used to �patch in� effects devices, however, effects are not usually added in this way. It is possible to use the �insert out� point, but not use the �insert in�, and instead bring the output of the effect back into the Omni on another channel. See the section �Alternate Omni Setups� for more on this. 10.5 Setting the Audio Track Playback Levels Once you have recorded an audio track in your music software, you may want to adjust the playback levels for these audio tracks. These playback levels will be controlled by your music software. The Delta H/W outputs 1-4 are connected directly to the Omni mixer. These Omni mixer inputs are what is known as �unity gain� inputs. Unity gain means what goes in is what comes out�no gain is added and none is attenuated (reduced).
