Disconnect Mode; Analog Output Headphones - RME Audio Hammerfall Digiface User Manual

24. Disconnect Mode

RME's exclusive Disconnect mode lets you adjust level, input selection and signal mix via your
computer, and simply detach the Digiface afterwards. With this, a stand-alone operation of the
Digiface gets possible. When the Digiface has been configured using Settingsdialog and To-
talMix, it won't loose those settings after detaching it from the computer. Provided, the Digiface
is operated with an external power supply, because the Digiface (as all HDSP I/O-boxes) does
not contain memory, so all settings get lost upon power-off.
If you do not need to record or playback audio with your computer, the Digiface can be used in
a fixed configuration, for example as:
SPDIF / ADAT / SPDIF format converter with monitoring
SPDIF AD- or DA-converter
Mixer / patchbay / distributor analog and digital
Headphone mixer
ADAT Matrix Router
what ever you just need!
The unit can also stay connected to a desktop computer, receiving its power from there. The
Disconnect mode will then cause the unit to be isolated from the computer, no longer be avail-
able to any software or other changes – an interesting security application.

25. Analog Output Headphones

Channels 27/28 of the Digiface are available on the front via one 1/4" unbalanced TRS jack
(stereo output). This output uses a hi-grade converter, therefore maintains a high signal to
noise ratio and low distortion (THD+N).
The output is a special low impedance type, ready to be used with headphones. But it can also
be used as high-quality (yet unbalanced) stereo Line output.
Like all other outputs, the level of channels 27/28 can also be controlled by TotalMix. The
monitoring perfomed on 19/20 of any input or playback channels (submix, like factory presets 1
and 2) is also controlled from To-
talMix.
In case the output should operate as
line output, an adapter TRS plug to
RCA phono plugs, or TRS plug to TS
plugs is required.
The pin assignment follows interna-
tional standards. The left channel is
connected to the tip, the right channel
to the ring of the TRS jack/plug.
