The 48K was added in firmware 2.5 and is accessed from the front panel menu. I would guess that the manual wasn't updated. You may want to confirm that with CARE tomorrow, though (contact info in my signature below).

Hi Yeah the DL 152 with 48 ins has the switch, the dl151 does not but has the menu buttons. My friend has two DL153s and he said they had to connect them to a PC to change the sample rate. Hopefully the updated firmware will let you change the sample rate from the menu buttons. I am thinking about buying two DL151s and the DNS9650 with dante card, in hopes of making a 48 input 48k remote record setup that I can control from my M32r. I know the M32r only supports 32 ins, but the dante card for the DNS 9650 supports 64 cahnnels at 48k . Looks like I have to buy all this stuff to find out if it will work. I like the small form factor of the DL 151 and dont need the outputs the other stage boxes have.
