1. ON – once you’ve connected the iTrack One Pre to your iOS device, open the recording app you’re
going to use: after a few seconds this green LED will light, confirming that communication
has been correctly established.
2. GAIN – adjust the recording level so that the LED halo [3] does not turn red.
3. Gain “halo” LED – this is integral to the GAIN knob; this illuminates green to indicate “signal
present” and turns red if the level reaches 0 dBFS, indicating clipping. Once clip level is
reached, the halo stays red for one second, so you will know that the level was too high even
if it was only for a very short peak.
4. Phantom power switch – this is a latching switch and should be set ON if you are using a
microphone which requires 48 V phantom power (condenser or active ribbon types).
5. 48V – this LED will light green when the phantom power is turned on and the microphone
is operating normally. If the LED turns red, it indicates that the iTrack One Pre has entered
“current limiting mode”, which means the phantom power voltage supplied to the microphone
has been reduced. In this case the mic may not work properly, and you should power the
iTrack One Pre from an external USB PSU. See “Power considerations” on page 7 for
more details.
