8.4 Analog Output
HDSP MADI offers a hi-quality analog monitor output. The short circuit protected stereo line
output provides high output level, low impedance, and is available via a 6.3 mm (1/4") TRS
jack. Therefore it is also suitable for a direct use with headphones.
The analog output is directly driven from the channels 63/64. Its output volume is controlled by
the hardware output faders of channel 63/64 in TotalMix. Additionally the analog output can
play back any input or playback signal (submix, for example Preset 5, 6 and 7).
RME's unique Speaker Protection reduces noise when switching the computer on and off, so
there is no problem even when using active monitors.
In case the output should operate as
line out, an adapter TRS plug to RCA
phono plugs, or TRS plug to TS plugs
is required.
The pin assignment follows
international standards. The left
channel is connected to the tip, the
right channel to the ring of the TRS
jack/plug.
8.5 MIDI
Hammerfall DSP MADI offers two MIDI I/Os via 5-pin DIN jacks. The MIDI ports are added to
the system by the driver. Using MIDI capable software, these ports can be accessed as MADI
MIDI In 1 (1), MADI MIDI In 2 (2), MADI MIDI Out 1 (1) and MADI MIDI Out 2 (2). The brackets
include the card number.
The MIDI inputs can not operate multiclient, so a MIDI input signal can not be distributed to
several programs at the same time. Such a functionality can be achieved with third party tools.
The third MIDI port, MADI MIDI In 3 (1) and MADI MIDI Out 3 (1), receives and transmits MIDI
data via MADI. This allows for a direct communication between systems with HDSP MADI
cards. Additionally MIDI data can be transmitted from/to RME's ADI-648. Also the ADI-648 can
be MIDI remote controlled without any additional line or cabling between computer (MADI card)
and ADI-648.
8.6 Internal Jumper
The internal blue jumper X4 is neither input nor output. It allows to change the voltage level at
the coaxial MADI output. In the lower position, the card generates 600 mVpp (according to the
specification). in case of a very long or 'lossy' coaxial cable, a higher output level might help to
maintain an error-free operation. In the upper position, the output level is 1.2 Vpp.
