4 TASCAM IF-AE8HR
TASCAM IF-AE8HR
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 of the four XLR-type inputs,
from the TDIF-1 source, or from an external inde-
pendent word clock source.
The IF-AE8HR allows high-resolution (up to 24 bits)
audio data to be transferred between units. No set-
tings are necessary to set word length.
In addition, four channels of high-frequency audio
data at 88.2 kHz or 96 kHz may be selected from the
front panel and transferred using the IF-AE8HR.
Separate word clock outputs are provided for either
high-frequency or normal-frequency data clocks.
When a high-frequency data rate (88.2 or 96) is
selected, the IF-AE8HR provides a choice of how the
data is physically transmitted: either using a single
high-speed connection (HI SPEED) or two parallel
“normal” speed connections (DUAL).
The audio data format output from the XLR-type
outputs may be selected from the front panel as either
AES (professional—PRO) or as IEC-60958 TYPE II
(SPDIF—CONSUMER).
Consumer and professional formats received at the
XLR-type inputs are automatically distinguished by
the unit.

1.1 Mounting, etc.

The IF-AE8HR is a 1U unit, designed to fit into a
standard 19-inch rack.
Included in the package are;
•The unit itself
•This manual
•A rack-mounting kit
•A 2 m (6 ft.) power cord
•Four rubber feet
If any of these items are missing, contact your TAS-
CAM distributor.
Install the unit in the 19” rack as shown below:

1Power switch and indicator

Push the POWER switch once to turn on power, and
again to turn it off. The POWER indicator lights
when power is supplied to the IF-AE8HR.
Note that settings made are not memorized. When-
ever the power is turned on, the CLOCK source is set
to WORD 3, the SAMPLING FREQUENCY is set to
44.1k 4and the CHANNEL STATUS is set to PRO
5.

2LOCK indicator

When a valid clock signal is received at the selected
clock source, this indicator will light.
If this indicator starts to flash, the IF-AE8HR is not
locked to the external clock (as specified by 3). This
