then this signal will appear on the Omni mixer channels 1 & 2 as well as mixer

channels 3 & 4. Generally, this is not a desirable scenario, and setup B is

designed to prevent this.

10.2 Monitoring the Record Inputs Using ASIO or EASI

If your music software allows you to monitor the software outputs of the

program, such as those programs using the ASIO or EASI drivers, then the

default Patchbay/Router setting (WavOut on the PC, or SM/ASIO Out on the

Mac) will work for monitoring the audio signal you are recording. Check your

software manual to see if it uses ASIO or EASI drivers, then make that selection

in the audio setup page. On the PC, the Delta ASIO drivers load automatically.

On the Mac, you must drag the proper ASIO driver into your software’s ASIO

folder (these instructions are included in your Delta installation instructions).

The Delta H/W (hardware) inputs are getting their signal from the outputs of

the Omni’s recording path (see “Omni Flow Chart), as we have already stated.

We still need to designate how we are going to monitor (hear) those signals that

we are trying to record. Again, if your software allows you to monitor the Delta

H/W inputs through the software, as most programs that use ASIO (or EASI) do,

you will also need to select that type of monitoring within the software’s audio

setup page. Most often, this is called “tape type monitoring” as it is similar to an

analog tape deck that allows you to monitor the inputs through the machine.

This is why, when you monitor through the software, that the Patchbay/Router

can be set to monitor the software outputs.

10.3 Setting Record Levels

There are a number of possible places in the signal flow that allow for adjusting of “gain,”

or the amount of level that is assigned. These are called the “gain stages.”

The Omni provides a gain adjustment control on Mic/Inst Channels 1 & 2. The

Delta 44 or 66 allows you to set the operating line level, -10, Consumer, and +4.

These are the gain stages that are used to set up your record levels using the

Omni and the Delta card. If you plan to use the Inserts on Omni channels 1 & 2,

this can add gain stages to the record setup (see section 10.4 for more on using

the inserts).

To set record levels for the Omni Mic/Instr channels:

1. Open the Delta Control Panel to the Hardware Settings page. In the

“Variable Signal Levels” section, set the level to +4 for the Delta inputs you

will be using. The Omni operates at +4, though it may be advantageous at

times to use a lower setting (Consumer or –10).

2. Start with the channel 1 & 2 gain controls all of the way to the left. Choose

one of the monitoring setups described in section 10.1 or 10.2.
