Modes of Operation
■Operation Modes: The FS-96 operates in either of the
following two conversion modes.
■■Normal Mode: This mode is used to convert the format and
sample rate of the 24 channels of digital audio. The input
digital audio signals will be converted to all of the signal
formats available on the FS-96.
When the FS-96 is in Normal mode, all advanced functions
are available such as the sample rate conversion, change of
bit resolution, signal routing, etc.
■■Bi-Direction Mode (☞p.25): This mode is used to perform
the bi-directional format conversions between the TDIF-1 and
AES/EBU interfaces. Bi-Direction mode is prepared for
situations such as connecting a digital audio recorder having a
TDIF-1 interface with a digital mixing console having an
AES/EBU interface.
In this mode, the advanced functions such as sample rate
conversion or signal routings are not available.
Selection of the operation mode is made by changing the input
format. If the input format is set to “BDIR”, the FS-96 is set to Bi-
Direction mode. If the input format is set to a format other than
“BDIR”, the FS-96 is placed in Normal mode.
NOTE: The FS-96 operates according to the settings stored in
the preset memories. The FS-96 always stores current preset
memory numbers when the power is turned off and the same
memory numbers are used when the power is turned back on.
■Configuration Modes: The operation settings are made in

used, selection is made for 12 channel pairs (1/2 ch – 23/24
ch). When the ADAT or the TDIF (including Bi-Direction
mode) is used, selection can be made for three groups
(GROUP A – C). There is no group selection for the SDIF
format.
After the optional settings are made, press the CANCEL key
to return to the OUTPUT SYNC screen. You cannot move to
the other screens, once you return to the OUTPUT SYNC
screen.
If the reference clock is set to a signal other
than the input audio signal (or the external
Word Clock signal synchronized to the input
audio signal), be sure to turn on the sample
rate converter. If the sample rate converter is
not activated, proper audio signals may not be
output.
NOTE: When “BDIR” (Bi-Direction mode) is selected as the input
format, the reference clock will be changed automatically to the
group A of the TDIF-1 input.

Selecting Reference Clock

■List of Reference Clock Signals: The following signals can
be used as the reference clock signal.
■■INT: selects the internal clock signal of the FS-96. The
frequency of the signal can be selected from the following 6
options — 32, 44 (44.1), 48, 64, 88 (88.2), 96 kHz.
■■WORD: selects the external Word Clock signal supplied to the
WORD IN connector. The frequency of the signal varies with
the setting of the external device.
■■INPUT: selects the Word Clock signal extracted from the
input audio signals. If the input audio signals consist of
multiple groups, you can select which group is used
(AES/EBU = INPUT 1/2 – 23/24 ch, ADAT & TDIF (including
Bi-Direction mode) = GROUP A – C).
NOTE: The output audio signals will be synchronized to the
reference clock signal with phase-level accuracy.
■Indication of Reference Clock and Sample Rate: The
selection of the reference clock signal and the sample rate of the
output audio will be displayed by the Reference Clock and
Sample Rate indicators on the front panel.
■■Reference Clock Indicators: The selection of the reference
clock signal is displayed by the Reference Clock indicators —
INT (internal clock signal), EXT (external Word Clock signal),
and INPUT (input audio signal). If no signal is present or no
synchronization is achieved for the input signal, the indicator
will flash.
■■Sample Rate Indicators: Each of the indicators will illuminate
when the frequency of the output signal is within a range of ±1
% of the labeled frequencies. If the signal is 64 kHz, both the
32 kHz and 44.1 kHz indicators are lit. Also, if the signal is
88.2 kHz, both the 44.1 kHz and 48 kHz indicators are lit.

Configuring Sample Rate Converter
According to the accuracy of the devices, there are slight
fluctuations or jitters in the sample rates of digital audio signals.
The FS-96 is equipped with an accurate clock generation circuit
and the input audio signals can be converted to accurate signals
by passing through the sample rate converter.
■Using Sample Rate Converter: Activation of the sample rate
converter should be determined by the settings of input format
and reference clock signal. If the audio signals are to be
converted to a different sample rate, you must turn on the
sample rate converter to obtain proper audio outputs. If the
output signals is to be synchronized to the input signals (or the
external Word Clock signal which is synchronized to the input
signals), the sample rate converters are not necessary. However,
we recommend to activate the sample rate converters all the
time.
If the sample rate of the input audio is different
from the frequency of the reference clock
signal, please be sure to activate the sample
rate converter. If the sample rate converter is
turned off, annoying noise may appear on the
audio signals.
NOTE: Status of the sample rate converter is displayed on the
SRC indicator on the front panel.
1. Press the SETUP key to place the FS-96 in Setup mode
and select the SAMPLE RATE CONVERT screen by
pressing the upper & lower Arrow keys.
The current status of the sample rate converter is displayed
on the screen.
2. Press the ENTER key to activate the parameter.
The current status is displayed with parentheses.
3. Select the activation of sample rate converters with the
right & left Arrow keys. Then, press the ENTER key to
store the setting.
The setting is stored into the current setting memory and is
reflected onto the actual setting.
(USE TO SELECT ON / OFF)
NOTE: When “BDIR” (Bi-Direction mode) is selected as the input
format, the sample rate converter will be automatically turned off.

The bit resolution (the number of quantization bits) of the output
audio signals can be changed from three options — 16 bits, 20
bits, and 24 bits.
NOTE: To change the bit resolution, you must turn on the
sample rate converter.
1. Press the SETUP key to place the FS-96 in Setup mode
and select the OUTPUT RES. screen by pressing the
upper & lower Arrow keys.
The current bit resolution is displayed on the screen.
The FS-96 automatically detects the bit resolution of the
input signals. Normally, the bit resolution of the input signals
is selected in this screen.
2. Press the ENTER key to activate the parameter.
The current selection is displayed with parentheses and the
other choices are displayed on the screen.
3. Select the desired bit resolution with the right & left
Arrow keys. Then, press the ENTER key to store the
selection.
The selection is stored into the current setting memory and
is reflected onto the actual setting.

Changing Bit Resolution
Activating Dither Function
When the bit resolution is decreased, the dither function can be
activated for the audio data.
■About Dither Function: When the bit resolution is changed in
a decreasing direction (e.g., 24 →20 / 16, 20 →16), distortion
may appear on the audio signals since the lower bits of each
sample are cut (LSB, 21st bit and later bits or 17th bit and later
bits). In this case, activating the dither function causes the output
audio signals to become more natural, by adding a slight noise
to the audio signals before changing bit resolution.
NOTES:
• Although the dither function can decrease distortion, the signal
to noise ratio may fall slightly by activating the dither function.
Also, activating the dither function may add noise to the audio
signals. Thus, activation of the dither function should be
determined by listening to the audio signals.
• The dither function is not applied if the bit resolution is changed
in an increasing direction (e.g., 16 →20 / 24, 20 →24), since
the vacant bits will be filled with zeroes.
1. Press the SETUP key to place the FS-96 in Setup mode
and select the DITHER screen by pressing the upper &
lower Arrow keys.
The current status for the dither function is displayed on the
screen.
2. Press the ENTER key to activate the selection.
The current status is displayed with parentheses.
3. Select the activation of dither function with the right &
left Arrow keys and press the ENTER key to store the
selection.
The selection is stored into the current setting memory and
is reflected onto the actual setting.
