Tascam DM-24 Supplementary Manual page 5

On the DM-24 EXTERNAL CONTROL page use the cursor to point to the JUMP
TO SCREEN icon and press ENTER. This will take you to the HUI control
screen.
SEND A-E refer to aux sends.
If you point to A and press ENTER the encoders on the LCD will show you all of
the levels for the first aux send on the channels viewed.
Using the cursors you can highlight the encoder area and adjust them 4 at a
time.
Pressing SHIFT flips the aux send controls from the POD knobs to the faders.
This allows you to control the aux sends 8 at a time with touch sensitive faders.
When PAN is solid it will show you the pan settings for all channels viewed on
the encoders on the LCD screen. Press ENTER and PAN will flash. This simply
removes PAN control from the POD knobs.
