1 Introduction
The TASCAM IF-AE8HR provides a convenient way 
of exchanging digital audio data between TDIF-1-
equipped devices, such as DTRS recorders, and AES/
EBU devices.
A single TDIF-1 connector carries eight channels of 
digital input and output. Four XLR-type connectors 
accept four two-channel input signals, and another 
four XLR-type connectors output four two-channel 
input signals.
The word synchronization is selectable, using a front 
panel switch, from any...

occurs if there is no clock signal or the signal is ±6% 
outside the nominal frequency. In these cases, once a 
valid clock signal is received again, the indicator will 
light steadily.
3CLOCK switch and indicators
This switch allows you to cycle between the six pos-
sible clock sources for the IF-AE8HR: the 
WORD 
SYNC – IN 
9 connector, the DIGITAL I/O (TDIF-1) 
8 connector, or any of the four two-channel AES/
EBU connectors (

NOTE
If WORD is selected as the clock source, and a high-
frequency sampling frequency has been selected 
(88.2k or 96k), but the incoming word sync clock is 
normal speed, note that this is not shown as an error 
by flashing indicators.

The format of the digital audio output from the AES/
EBU output connectors

AWORD SYNC – THRU (AUTO TERM)
This BNC connector echoes the word clock which is 
input at the 
WORD SYNC – IN connector 9. 
If no connection is made to this connector, it is auto-
matically terminated.
BWORD SYNC – OUT (STD Fs)
This BNC connector outputs a standard-frequency 
word clock: either 44.1 kHz when 
44.1k or 88.2k is 
selected, or 48 kHz when 
48k or 96k is selected.
CWORD SYNC – OUT (HI Fs)
This BNC connector outputs a high-frequency word 
clock: either 88.2...
