48 Volt Phantom Power. Studio-series interfaces provide 48V phantom power for
the microphone inputs. Pressing the 48V button switches phantom power on and off
for all microphone inputs; the button will illuminate in blue when phantom power is
available on the microphone preamplifiers. .
WARNING: Phantom power is only required for condenser microphones and
can severely damage some dynamic mics, especially ribbon mics. Therefore,
switch phantom power off when it is not required. Consult the user documentation
that came with your microphone before engaging phantom power.
XLR connector wiring for phantom power:
Pin 1 = GND Pin 2 = +48V Pin 3 = +48V
Input Meters. These LED meters show the input level of the analog inputs
on your Studio-series interface. The red Clip LED will illuminate when your
input signal reaches -0.5 dBFS. At this level, the signal will begin to overload
the analog-to-digital converters and exhibit signs of clipping. Use the gain
controls to keep the signal below this level.
Output Meters. These meters display the signal level received from the first two
driver returns (Main Left/Right). These meters have the same range as the input
meters and display the signal level before the main output level control.
Sync LED. This light indicates if your Studio-series interface is in sync with your
computer. When no sync is available, this light will flash red/blue.
Direct Monitor. The Direct button blends the source of what is heard through the
Headphone and Main outputs in the following manner:
•
When Direct Monitoring is disabled, you'll only
hear the playback from your computer.
• When Direct Monitoring is enabled, the button will illuminate blue, and you'll
hear a 50/50 blend of the playback from your computer and input source signals.
Cue A/B. This button allows you to switch the source that you listen to through your
headphone output. When the button is not illuminated, playback streams 1 and 2
will be routed to the headphone output. Press the button to route playback streams
3 and 4 to your headphones instead.
Input Gain Control. These knobs adjust the gain for your audio interface inputs.
Headphone Level. This knob controls the level of the rear panel headphone output.
Main. The main knob controls the output level for the main left/right outputs on the
back of your Studio-series interface and has a range of -80 dB to 0 dB. This control
provides attenuation only.
