TASCAM SERIES 102i / SERIES 208i
There is no valid signal or it is
disconnected.
This unit and the device that
is optically connected are not
synchronized.
This unit and the device that
is optically connected have
different sample rates.
There is no valid signal or it is
disconnected.
This unit and the device that
is optically connected are not
synchronized.
This unit and the device that
is optically connected have
different sample rates.
NOTE
i When the unit and the computer are not connected, "No
Device" is shown for the "Firmware Version" and "Device"
items.
i When the 2 Sample Clock Source item is set to "Internal", the
Clock Source Status item will appear dimmed as "----------".
2 Sample Clock Source
Use this to set the sampling clock source.
Option Meaning
The unit's built-in clock is always
INTERNAL
used.
OPTICAL A The clock signal input through the
OPTICAL IN (S/MUX) connector
is used.
If the connected device is a
OPTICAL B
TASCAM device and 3 Rate
(SERIES 208i only)
setting is "Auto - TASCAM Device",
the input clock signal will be
automatically identified and set.
WORD
The clock signal input through the
WORD IN connector is used.
(SERIES 208i only)
NOTE
i When set to OPTICAL A, OPTICAL B or WORD, if no
signal is input through the corresponding connector or
synchronization becomes impossible, the status will appear
in the Clock Source Status item and this unit's STANDBY
indicator will blink.
i When connecting multiple digital devices to the SERIES 208i,
synchronize them to a system word clock and input word
clock supplied by the master clock device to the SERIES 208i.
i After changing the clock source, proper continuation of
playback/recording might not be possible, so you should
restart the playback/recording software that you are using.
3 Rate items
Use these to set the connected OPTICAL (S/MUX) sample
rates.
If the connected device is also a TASCAM product, select
"Auto - TASCAM Device" to set this automatically.
Options: Auto - TASCAM Device, Manual - 44.1kHz/48kHz,
Manual - 88.2kHz/96kHz, Manual - 176.4kHz/192kHz
4 Buffer Size (Windows only)
The Windows driver for the unit stores the audio signals
transferred to and from the computer temporarily in a buffer.
This buffer size can be adjusted.
Smaller buffer sizes result in less audio signal delay (latency),
but require high-speed processing by the computer.
If the processing cannot keep up, for example, due to other
system operations, clicking and popping noises might occur
and the audio signal might even drop out.
Increasing the buffer size will stabilize operation and
suppress negative effects on audio signals, but the delay in
audio signals sent to the computer will increase.
You can use the slider on the panel to adjust the buffer size,
according to the use conditions.
Use the slider to select fixed values that increase from left to
right.
Options: 4 Samples, 8 Samples, 16 Samples, 24 Samples,
32 Samples, 64 Samples, 128 Samples,
256 Samples, 512 Samples, 1024 Samples,
2048 Samples
