MOTU 2408 Mk3 24-bit/96kHz Audio Interface Analog S/PDIF ADAT & TDIF i/o

Description

Here is a very clean example of the MOTU 2408 Mk3 audio interface. I am the original owner and the unit has been treated with care and comes to you from a non-smoking environment. There's a tiny amount of scuffed paint on the rear of the racking holes (not visible from the front) and a couple of small marks near the power switch.
See my separate listing for a PCIe-424 to go with this interface.
The 2408 Mk3 is designed to cater for almost every I/O requirement, offering eight-channel analogue in and out as well as 24 channels of ADAT and TDIF-format digital I/O.
The rear panel has the following connectors:
Word clock in and out. The Word in socket also doubles as a Video input allowing the interface to resolve directly to a video signal.
S/PDIF. There is one stereo input and two stereo outputs. The second output simply duplicates the output of the first and allows the connection of a further digital device such as a DAT machine. These sockets also double as SMPTE timecode input and output, and the second output will still deliver S/PDIF digital audio even when SPMTE in and out are required.
TDIF connectors. There are three 25-pin 'D' connectors, each of which handles eight channels of digital I/O. These share the output with the ADAT optical outputs, although the inputs can only be one or the other.
The Audiowire socket for connection to the PCI-424 card (not included - see my separate listing for this item).
Three pairs of ADAT optical connectors for up to 24 channels of ADAT digital I/O.
Two rows of eight quarter-inch balanced jack sockets for eight channels of analogue I/O.
One pair of balanced quarter-inch jack sockets for main output. These duplicate the output of analogue channels 1 and 2, if one of the three eight channel banks into which the 2408 Mk3 is internally divided has 'analogue' selected as the desired format (using the PCI-424 configuration window).
The final button (Set) on the front panel is only used when the interface is operating in stand-alone mode. In this mode the 2408 becomes a format converter, and the Set button cycles through the Clock, Source and Bounce settings that determine how the interface operates in this mode. The Clock setting determines to which digital clock source the 2408 is slaved. The options are Internal, Digital (from the ADAT or TDIF inputs), Word Clock, Video or LTC.
The Source setting determines which audio source will be the source of the transfer (in stand-alone format converter mode). This could be analogue (at +4 or -10 dB), stereo S/PDIF, ADAT (each of the three banks separately or all together) or Tascam (as per ADAT). The Bounce setting lets you redefine the order of tracks after conversion.
The 2408 will support up to 24 simultaneous channels of I/O. This is when running at 44.1 or 48 kHz, at which sample rates the three internal busses will carry eight channels each (digital or analogue). When operating at 88.2 or 96 kHz, four channels of TDIF or ADAT digital are available per bank.
