MAC OPERATION
After installing the Firefly 302 USB driver and
software to your Mac computer, enter the Audio
MIDI Setup application and you should be able
to select the Phonic Firefly 302 USB as your
default input and output device.
Also in the Audio MIDI Setup, you will be able to
adjust volume levels of your various input and
output signals, as well as the sampling rate and
resolution you want to use. Users are able to
select between 44.1, 48, 88.2, 96, 176.4 and
192 kHz sampling rates. Resolution can be se-
lected between 24-bit, 20-bit and 16-bit. Both
the sampling rate and resolution can be adjust-
ed in your DAW software as well (depending on
what software you use).
Also in the Audio MIDI Setup, tracks can be
muted at will, and input signals can be set to
'thru', which - put simply - will return the input
signals directly back to their corresponding out-
puts.
The input and output channel names listed cor-
respond with each of the Firefly's input and out-
puts. Channels 1 to 6 on the input correspond,
in order, with analog inputs 1 and 2 (listed in
the Audio MIDI Setup as channels 1 and 2), the
microphone input (channels 3 and 4) and the
S/PDIF left and right input signals (channels 5
and 6). The output channels 1 to 4 are, in or-
der, analog outputs 1 and 2 and S/PDIF outputs
left and right.
