11: How do I set ZephyrExpress for my microphones?
From the Utility screen, select the Audio menu and then the Microphones submenu. Each
microphone has its own submenu, where you can:
· set
sensitivity ( 60 dB , 45 dB , or 30 dB for various ribbon, dynamic, and condenser
microphones; or line to use that input with a line-level source). If you can’t get a
good meter reading no matter how high you turn a mic’s GAIN knob, try a higher
sensitivity; if a mic sounds distorted at any setting of the GAIN knob, try a lower one.
· turn 48 volt
phantom power on or off. Phantom power is not available when sensitivity
is set to line .

NOTE:
Phantom power may damage improperly-wired or ribbon microphones. Leave
it off unless you’re sure a condenser mic needs it.
· turn a
low cut filter on or off, to reduce rumble and wind noise. The filter is 12
dB/octave, 3 dB down at 100 Hz.
· Substitute a test oscillator for that microphone’s signal. If a microphone’s audio is
missing and replaced by a steady tone, make sure the mic’s test tone is set Off .
· The
Microphones submenu also lets you turn a dual-channel limiter on or off.
The phantom power selection is remembered even while ZephyrExpress is unplugged.
When you finish a remote broadcast, turn phantom power off as a courtesy to the next
user.

HOT TIP:
When phantom power is turned on, it’s supplied continuously — regardless
of how the routing switch is set. That’s so you can use the routing switch as a
microphone mute, without worrying about a turn-on “thunk”.
Turn each microphone on or off by pressing the small gray routing switch next to its gain
knob, on the upper left of the front panel. LEDs indicate whether the mic is being sent to
codec channel A, channel B, both, or is disconnected. If you’re sending a mono signal,
use channel A.
12: How do I use line-level sources?
The rear-panel Line input jacks will accept XLR or 1/4” plugs, balanced or unbalanced.
Wiring details appear later in this booklet.
Line sensitivity can be adjusted in the Utility
Screen’s audio submenu: select Profess for +4dBu sources, and Consumer for -10dBu
sources.
