It’s Time to Locate Everything…
No matter how fast you want—or need—to get
started, take advantage of this simple map of the
territory: it provides the Fast Track overview of
the D8B. It’s amazing how artistically supportive
this console is. It’s well worth your time to take a
look at all the controls so you can put them to
work efficiently.

Each channel contains:
• XLR mic input. Be sure the MIC button is pressed
down on the control surface channel strip.
• Phantom power On/Off button depending on
mic requirements.
• 1/4" TRS line input—balanced or unbalanced.
Be sure the MIC switch is in the up position
on the control surface channel strip.
• 1/4" TRS channel insert/direct output jack.

This is where you plug in the optional I/O cards of
your choosing, to customize the Digital 8•Bus for
your own application.
There are three slots assigned as TAPE IN/OUTS.
Each slot provides I/O for 8 channels, so you can
add up to 24 tape sends and returns, or additional
inputs and outputs.
• TO TAPE (OUTPUT) – The D8B can route any
channel in Fader Banks 1, 2 and 3 to the
multitrack through these connectors. In addition,
the bus outputs in Fader Bank 4 (MASTERS) can
be routed out the tape outputs.
• FROM TAPE (INPUT) – Multitrack outputs are
fed back into channels 25–48 (Fader Bank 2)
through these connectors. Depending on the
specific I/O card, these inputs will receive any
line-level analog or digital signal.
Each I/O card contains its own labeling protocol,
but the fundamental concepts described above
pertain to all.
1 Analog I/O (AIO•8)
• Each 25-pin D-sub connector handles 8 balanced
analog channels.
• Top connectors send line-level outputs to the
multitrack (or other line-level equipment).
• Bottom connectors receive line-level analog
signal from the multitrack outputs (or other
line-level equipment).
• Each card offers I/O for 8 channels.
• Connectors are compatible with TASCAM
DA-88, 25-pin analog connectors.
2 Apogee Digital I/O (DIO•8)
• Two digital-format ins and outs: ADAT optical
(fiber optic connections) and TASCAM TDIF
(25-pin D-sub connections).
• Select one digital format at a time in the Setup
screen.
• One BNC sync connector for master clock connec-
tion from the D8B to TASCAM clock recipient.
• Use the DIO•8 card as a format converter be-
tween either optical and/or TDIF.
