IMPORTANT SAFETY INSTRUCTIONS
TASCAM FireOne 9
2 - Features of the FireOne
4 PAD switches
The PAD switch is used to attenuate input signals by 20 dB.
Use the PAD switch with high-level output devices that would
otherwise overdrive the inputs and cause distortion.
5 MIX control
The MIX control is used to balance the audio levels from
inputs with signals coming from the host computer. When
the knob moved fully counter-clockwise (pointer at “7 o’
clock”), only the signals connected to the FireOne input
jacks will be heard at the LINE OUT and PHONES outputs.
When the MIX control is turned fully clockwise (pointer
at “5 o’clock”), only the audio coming from the host
computer will be heard. At any adjustment point between
these two extremes, the expected proportion of both the
inputs and the host computer generated audio will be
heard.
6 LINE OUT level control
The LINE OUT control is used to adjust the level of audio
on FireOne’s LINE OUTPUT connectors. In most cases, the
line outputs will be connected to an amplifier or powered
speakers and will control the audio level in your studio.
This control is independent of the headphone levels.
7 PHONES level controls
Each of the two PHONES jacks on the front of the FireOne
can drive a set of headphones. The independent PHONES
LEVEL controls permit you to adjust the listening level of
each PHONES output independently.
8 FireWire indicator
This indicator lights when a valid FireWire (IEEE.1394)
connection is made between the FireOne and the host
computer.
9 MIDI IN and OUT indicators
These light momentarily when MIDI activity is detected
on the external MIDI IN and OUT ports.
0 STEREO METERS
The 12-segment stereo meters on FireOne permit high-
resolution observation of input and output signal levels.
The first 9 segments (-42dB … -4dB) are green. The next
two segment (-2dB, 0dB) are amber. The last segment
(OL) is red. The point in the FireOne signal flow that is
metered corresponds to the program that is sent to both
the LINE OUT’s and the PHONES.
The metering point is just after the MIX control,
which suggests the following method for adjusting
input signals:
1. Turn the MIX control completely counterclockwise
so that only the input signals are present on the
meters.
2. Adjust the input signals with the input GAIN
controls such that the loudest peaks in the signals
will only occasionally light the amber (-2dB) indi-
cators.
This permits maximum signal at the input to the
converters but prevents clipping, affording the highest
signal-to-noise ratio for the recording signal.
q TRANSPORT controls
A standard set of transport buttons (Ô, , ª, ¥, and
º) are provided. In most cases these controls will map
naturally to the transport controls in the audio application
software you’re running on your computer.
w JOG/SHUTTLE wheel
A weighted JOG/SHUTTLE wheel on the FireOne is used
to help you quickly locate to a section of your current
project. Depending on the application-specific plug-in
and settings, you may also be able to use this jog wheel
for other functions. A set of LED’s under the wheel pro-
vides various forms of visual feedback, and can be used
as a visual metronome display when you set your appli-
cation to send MIDI clock information to the FireOne
Virtual MIDI port.
e FUNCTION keys
A set of 8 buttons labeled F1, F2, …, F8 are provided in
an arc just above the transport buttons. These perform
a variety of functions, depending on the control surface
capabilities of the host software. See the application-spe-
cific notes for information on how to set up these controls
with the audio software you use.
r SHIFT button
SHIFT is used to double the capabilities of the FireOne
control surface, by providing an alternate function for
each control listed above (transport, JOG/SHUTTLE
wheel, and FUNCTION keys) as supported by the host
software.
t PHONES 1 and 2 outputs
Two PHONES outputs with independent level controls are
provided on the FireOne, so you and a friend can both lis-
ten at the levels you’re comfortable with.
Note that plugging in headphones doesn’t affect the level
at the LINE OUT connectors – you can adjust room and
phones levels independently.
y GUITAR IN
The connector labeled GUITAR IN on the front panel is
an instrument-level input that can be used in place of
the “combo” (XLR/phone) jack on the rear panel. A
slide switch on the rear panel of the FireOne (“FRONT-
REAR”) selects which of the two connectors is routed
to input B. The guitar input is matched to the higher-
impedance of instrument outputs.
