There are two ways to do this:

1. If you are recording back to another track, your file will still be at 24bit 48kHz. You would want to apply dither only if you are looking to go to 16bit 44.1kHz for CD. Once you record back to another track with your limiter, etc. (with dithering off in your limiter) you will then have your final track at 24bit 48kHz. You can then export the region as a file and select 16 bit 44.1kHz.

From the Reference Guide (Page 288):

In the Export Selected dialog, set the File Type,
Format, Bit Depth, and Sample Rate. In addition,
specify the Conversion Quality, and choose the
Destination Directory.
When you export regions to a lower bit depth,
Dither (with or without Noise Shaping) is applied
as shown in Table 16.
The Dither used for any conversion is the
Digidesign Dither plug-in (with or without
Noise Shaping enabled, as noted in Table 16).

Table 16. Dither and Noise Shaping with Export
Selected dialog
Bit Depth Dither Noise Shaping
24-bit to 24-bit No No
16-bit to 24-bit No No
24-bit to 16-bit Yes Yes
16-bit to 16-bit No No


2. Another option is to use the Bounce to Disk feature with the Dithering on in your Limiter and bouncing to the correct bit depth and sample rate. Double check your tops and tails of each track after your bounces.
