You’ll get the same level as is coming into the channels of your GLD, assuming you’re recording either the input socket or a prefader direct out. Be aware that the metering on the GLD is shown in “analog” where the highest level on the meter is +18, which is actually 0dBFS. On this console, 0dBFS is at 18dBu.
If you have your input signals around 0 dBU on the GLD metering they’ll be around -18dBFS in your DAW, which is the standard nominal level. Obviously that’ll sound much quieter than a mastered commercial recording, but that’s to be expected.
If you’re using -18dBu as your input level, everything will be very quiet and will be at -36dBFS in your DAW.
What sort of levels are you getting into Pro Tools?
