Analog inputs.
The analog inputs of the PHASE 28 system are equipped with
high-quality preamplifiers, with which you can manually control the
gain of the converter. Here, you can connect the AUX or TAPE
outputs of a mixing board, instruments with line level output, a
tape recorder or similar peripheral gear.
The PHASE 28 system offers you two high-quality analog input jacks, which can be
addressed separately. The connections are in 6.3 mm cinch format and offer a balanced
signal path to minimize interference. Of course, non-balanced mono cinch cords can also
be connected; the unused phase is then automatically connected to the analog signal.
On the slot plate of the PCI card, there are two control sliders, which you can use to
adjust the input stages manually and very precisely to your needs. To do so, please use a
small flathead screwdriver. However, never insert it into your power supply's fan! ;-)
Beginning at approximately -1 dB (0 dB corresponds to 2.1 V RMS @ 1kHz), the red
LEDs signal the threat of clipping at the inputs. The exact level converted by the 24-bit
A/D convertors can be viewed using the PHASE ControlPanel or common audio software.
If, despite being manually turned to the maximum level, a connected device supplies too
low of a signal, you can use the controllers in the PHASE ControlPanel to additionally
increase the level in 0.5 dB increments. However, this amplifier stage does not provide
optimal signal quality.
In the drivers as well as in the PHASE ControlPanel, the inputs are viewed as a stereo
pair. As a rule, you can also combine the two channels for mono use in common audio
editors.
Practical tip: While recording, try to achieve as high a recording
level as possible to benefit best from the wide dynamic range of
the 24-bit converter. As a rule of thumb for good recordings, al-
ways take the following into account: a clean "take" is much more
valuable than the best plug-in for later sound correction.
