Need help with DTI-PRO 32


Hi,
I recently purchased a DTI-PRO 32 (without manual) to uprgade from a DTI-PRO (not 32). I can't figure out what the settings are. There seem to be 7. They are 1. all lights off 2. bottom light on 3. middle light on 4.top light on 5. top and bottom on 6. top two on 7. bottom two on.
I know there are 3 dither settings (maybe 4)- 18 bit, 20 bit and 24 bit. If anyone could tell me what the settings are or tell me how I can obtain a manual, that would be great! Thanks in advance.

I believe the lights go in the following

none,16bit,18bit,20bit,22bit,24bit,HDCD pass through
I have found the DTI Pro to be a big improvement over the DTI 2.0.
I have been thinking about getting the Pro 32 to feed a Bel Canto Dac.
How much better sonically is the Pro 32 over the Pro?
