The new 2408MK3 provides 96khz sampling rates on all analog and
digital I/O. The 2408Mk3 has a built in synchronizer for video sync,
word sync, and SMPTE sync. The 2408M3 ships with the PCI 424 card,
which provides four Audiowire ports and DSP mixing for 96 input to
output with 1.6ms patch through delay.
The 2408MKII has improved analog connections over the original 2408.
The original 2408 had RCA jacks that were unbalanced and fixed at -10db
line reference. The 20 bit converters on the 2408 got 98 db of dynamic
range.
The 2408 MKII has TRS balanced/unbalanced 1/4 phone jacks for the
analog connectors. Signal level is switchable between +4 and -10 db.
The converters are 24 bit with a dynamic range of 105 db. All other
specs on the 2408 MKII are the same as the original 2408. The cost of
the 2408 MKII is the same as the 2408.
