Looks like the manual has been updated: http://cdn.sounddevices.com/download/guides/MixPre6-UG_en.pdf
I'd love for someone to make a simple how to guide to set up the recorder in "taper mode," All I want is 6 channels, 4 xlr in, each pair of ISOs controlled by a single knob, and 1/8 inch line in for 5/6.
From out of the box, something like this ...
1. Set to Advanced mode (System/Mode menu)
2. Link channels 1 and 2 (Press channel 1 knob to enter channel 1 screen, goto page 3 and set linking to '1-2'). While in the channel 1 screen, you can choose your input type, phantom, low cut etc too.
3. Link channels 3 and 4 (Press channel 3 knob to enter channel 3 screen, goto page 3 and set linking to '3-4'). While in the channel 3 screen, you can choose your input type, phantom, low cut etc too.
4. Link channels 5 and 6 (Press * button to enter channel 5 screen, goto page 2 and set linking to '5-6'). While in the channel 5 screen, set your input to Aux In 1. This will auto set channel 6 to Aux In 2. By default Aux In is set to Line.
Pretty much that's it. You just need to worry about setting your gain.
Once you've set up, consider saving the setup as a Preset, so you can recall all of this with a touch of a button.
