9.9 Instrument / Line
The INST/LINE inputs allow to attach both balanced line signals as well as unbalanced instru-
ment signals via 1/4" TRS jacks. It handles standard line sources like keyboards, mixing desks,
effects devices or consumer-type units perfectly well. Changing the input impedance to Hi Z
(470 kOhm instead of 5.6 kOhm) turns INST/LINE into a perfect instrument input.
The input Inst/Line operates fully servo-balanced even with HI Z activated.
The maximum input level is +21.5 dBu unbalanced and +27.5 dBu balanced. The latter can only
be used with the analog output, as the AD-converter reaches full scale level at exactly +21 dBu.
Inst/Line uses an active servo-balanced input stage that is added in front of the microphone
input. The circuit uses an innovative design with particularly low-noise op-amps. Nevertheless it
is needless to say that one can't prevent a higher noise at higher gain settings, when comparing
the front with the rear input. In practice this usually stays unnoticed, as the sources generate
much more noise than the Micstasy.
Because of the lower maximum level the GAIN display starts at 00, and because of the higher
self-noise it ends at 50. Changing from the rear to the front input, the gain setting changes
automatically in case the current value had been outside the range available on the front.
10. Presets
The channel settings of the Micstasy can be stored to eight different user presets. The settings
performed in the right side of the front panel are not stored: Clock, Sample Rate, Analog Out
and Remote. This way, the channel settings can be used with different clocking and independ-
ent from the current operating situation (front panel or remote operation).
After pressing the SAVE button and selecting one of the 8 internal memories with the rotary
encoder, the current channel settings will be stored as preset by pressing SAVE a second time.
After pressing the RECALL button, selecting a preset with the rotary encoder and pressing
RECALL a second time, the selected preset is loaded and the state of the channels is updated.
Note
: The keys SAVE and RECALL provide an exit functionality. When Save is pushed a sec-
ond time without turning the encoder knob first (no preset is selected), the Save process will be
exited immediately. Recall acts in the same way. As one can change from any function directly
to Save and Recall by pushing these buttons, ANY setup process can be exited immediately by
a quick double-push on either Save or Recall. Also it is not necessary to wait 6 seconds until
the flashing stops or the setup menu is exited automatically – just do the double-push.
