The Model UC-8 is a universal format converter that converts the format of the digital input
signal to different format. It can convert between adat digital and AES/EBU, adat digital and
TDIF-1, and AES/EBU and TDIF-1.
By inserting the UC-8 between two digital recorders which have different digital formats, you
can digitally transfer signals between them (44.1 kHz/48 kHz, 24-bit digital signals only).
Please read this manual thoroughly before using the converter.

1. POWER switch and indicator
Turns on or off the power to the UC-8.
When on, the indicator illuminates on green.
2. Fs SELECT switch and indicator s
Selects the Fs when converting an adat digital signal
that does not have the Fs status information in the
signal. You can select 44.1 kHz or 48 kHz, and the
appropriate indicator illuminates.
When converting signals which contains the Fs status
information in the signals, it takes priority and the
setting of the Fs SELECT switch is ineffective.
3. 75Ω TERMINA TION switch
Set the switch to ON when receiving an external word
clock. Otherwise, set the switch to OFF.
4. CLOCK SELECT switch
Selects the master clock.
See "Basic Connections and Settings" for details.

Basic Connections and Settings
<Notes>
• Make sure that the unit is turned off when connect or disconnect cables.
• Make sure that the unit is turned off when changing the select switch setting. If you change the setting when
the power is on, unwanted noise may be generated.
• If you try to convert a signal other than signals with a 44.1 kHz or 48 kHz sampling frequency and 24-bit
quantization, the UC-8 may generate noise.
Between adat and TDIF-1 devices
To convert an adat signal to a TDIF-1 signal or vice verse, connect the devices and set the switches on
the front panel as follows:
<Fs SELECT switch setting>
In this case, you do not have to set the Fs SELECT switch because the Fs of the converted signal depends on
the Fs information in the TDIF-1 signal.

<About WORD clock>
In the connection example above, the UC-8 is locked to an
incoming digital signal (adat or TDIF-1).
However, if the while system is lock to another WORD clock,
feed the master clock to the WORD INPUT of the UC-8 as
well as the other devices. In this case, set the CLOCK SELECT switch to "WORD" and the 75Ω TERMINATION to "ON".
If you use the TASCAM DA-88 for a TDIF-1 device in the
connection above, connect the WORD OUT connector of
the UC-8 and the WORD IN connector of the DA-88, so that
the word clock is supplied to the DA-88 from the UC-8.

<Fs SELECT switch setting>
If both of the AES/EBU INPUT and OUTPUT connectors are connected to an AES/EBU device, you do not
have to set the Fs SELECT switch when converting an adat signal to AES/EBU signals, because the Fs of the
converted signal depends on the Fs information in the AES/EBU signal. However, if you convert an adat
signal to AES/EBU signals when the AES/EBU INPUT connectors are not connected, set the Fs SELECT switch
correctly to match the Fs of the adat signal.
