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.  
AES (professionalPRO) or as IEC-60958 TYPE II  
(SPDIFCONSUMER).  
Consumer and professional formats received at the  
XLR-type inputs are automatically distinguished by  
the unit.  
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.  
1.1 Mounting, etc.  
The IF-AE8HR is a 1U unit, designed to fit into a  
standard 19-inch rack.  
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.  
Included in the package are;  
The unit itself  
This manual  
A rack-mounting kit  
A 2 m (6 ft.) power cord  
Four rubber feet  
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.  
If any of these items are missing, contact your TAS-  
CAM distributor.  
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.  
Install the unit in the 19rack as shown below:  
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  
normalspeed connections (DUAL).  
The audio data format output from the XLR-type  
outputs may be selected from the front panel as either

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

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.  
DUAL mode (Fs=88.2k or 96k)  
Data is transferred in over two channels in the DUAL  
mode. In high-frequency sampling modes (88.2k and  
96k), there is twice the amount of data compared to  
the usual modes (44k and 48k). In DUAL mode, one  
XLR-type connector carries the data for one channel,  
allowing four channels in total to be transferred.  
3 CLOCK 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 (DIGITAL I/O (AES/EBU) INPUTS  
(1/2, 3/4, 5/6, 7/8) 7), as shown by the indicators to  
the right of the switch.  
In this mode, channel 1 is carried by connector 1-2,  
channel 2 by connector 3-4, channel 3 by connector  
5-6, and channel 4 by connector 7-8.  
HI SPEED mode (Fs=88.2k or 96k)  
In the HI SPEED mode, data is transferred at double  
speed. As mentioned above, in high-frequency sam-  
pling modes (88.2k and 96k), there is twice the  
amount of data compared to the usual modes (44.1k  
and 48k). Here, the transfer speed is doubled, so that  
one connector can carry two channelsdata.  
NOTE  
There should usually never be more than one word clock  
signal in a digital audio system. If there is more than one  
word clock, at worst, damage may occur to speakers,  
amplifiers, etc. as a result of high-frequency noise gener-  
ated by word clock incompatibilities, etc..  
In theory, this would allow eight channels to be trans-  
ferred at high speed, but for the reason below, only  
four channels may be transferred using the IF-  
AE8HR.  
4 SAMPLING FREQUENCY switch and  
indicators  
This switch allows you to select the sampling fre-  
quency at which the IF-AE8HR outputs data, either  
to the XLR-type connectors, or to the TDIF-1 con-  
nector: 44.1k, 48k, 88.2k or 96k.  
NOTE  
NOTE  
In TDIF version 2 format, only the DUAL mode is sup-  
ported. If HI SPEED is selected, only DIGITAL I/O  
(AES/EBU) connectors 1-2 and 5-6 are used. Therefore,  
INPUT and OUTPUT terminals 3-4 and 7-8 cannot be  
used in this mode.  
There are also two other settings that may be selected  
with this switch: DUAL and HI SPEED, which only  
become options when one of the high-frequency  
options (96k or 88.2k) has been selected. Repeated  
presses of this switch will cycle between the follow-  
ing settings:  
Error modes  
These LEDs are also used as error indicators, to show  
an error condition with regard to the input signals.  
The selected frequency indicator will flash to show  
an error under the following circumstances. When  
appropriate steps are taken to correct the problem, as  
shown below, the indicator will stop flashing and will  
light steadily.

DUAL mode and HI SPEED mode (AES  
format)  
The signals at the four AES/EBU inputs have dif-  
ferent sampling frequencies. Make sure that all sig-  
nals received at these connectors are at the same  
sampling frequency.  
Usual mode (FS=44.1 or 48)  
In this mode, one XLR-type connector carries two  
channels of data. Since the IF-AE8 is provided with  
four such XLR-type connectors for input and four for  
output, the data for eight channels can be transferred  
in total.  
Incorrect data is being received at one of the AES/  
EBU inputs. Make sure that all data sources are  
correctly set up.

of the output connectors remain the same, regardless  
of the data format selected. As mentioned below, the  
input format is automatically selected, and no setting  
is necessary to determine the input data type.  
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.  
NOTE

Since the consumer standard does not provide for  
high-frequency (88.2 kHz or 96 kHz) data rates, any  
attempt to select CONSUMER and either of the high-  
frequency rates (88.2k or 96k) will not work. This is  
shown by the PRO indicator flashing for about two  
seconds, and then returning to a steadily-lit state.

Use this connector to connect a suitably-equipped  
TDIF-1 digital audio unit (e.g. a DTRS recorder or a  
TASCAM digital mixing console).  
These balanced XLR-type connectors output digital  
audio data in AES/EBU professional or in consumer  
format, depending on the selection made with the  
CHANNEL STATUS switch 5.  
The signals received at this connector can be selected  
as the word clock source using the CLOCK switch  
3.  
The sampling frequency of the output data depends  
on the setting of the SAMPLING FREQUENCY  
switch 4, and the currently-selected clock source  
3.  
NOTE  
Note that you should always use genuine TASCAM cables,  
or cables which have been approved for use with TDIF-1  
interfaces by TASCAM.  
7 DIGITAL I/O (AES/EBU) INPUTS  
(1/2, 3/4, 5/6, 7/8)  
Although these cables appear similar to certain types of  
computer cables and use similar connectors, the cables  
themselves are very different, and the different electrical  
characteristics of the cables can cause damage to the  
equipment connected with the wrong cables.  
These balanced XLR-type connectors accept digital  
audio data in AES/EBU professional or in consumer  
format. The data type is automatically selected and  
no setting is necessary.  
If the use of cables other than TASCAM cables causes or  
results in damage, the warranty is voided.  
Note that there are four independent detection cir-  
cuits, meaning that a mix of consumer and profes-  
sional format signals may be input at these four  
inputs. However, all the signals must be at the same  
sampling frequency.  
9 WORD SYNC IN  
The BNC connector accepts a word clock signal from  
an external source. It can be selected as the word  
clock source for the IF-AE8HR using the CLOCK  
switch 3.  
Also note that if a signal with emphasis is received at  
any input, the resulting output signals will all contain  
emphasis.  
If a high-frequency sampling frequency (96k or  
88.2k) has been selected, it is possible to use either  
the appropriate high-frequency word clock, or the  
corresponding standard-frequency word clock.  
The signal received at any of these connectors can be  
selected as the clock source for the IF-AE8HR using  
the CLOCK switch 3

These clocks output from B and C may or may not  
be the same as the clock received at WORD SYNC –  
IN 9 and retransmitted through WORD SYNC –  
THRU (AUTO TERM) A. However, they are always  
the word clock selected using the CLOCK switch 3.  
If no connection is made to this connector, it is auto-  
matically terminated.  
B WORD SYNC OUT (STD Fs)

selected, or 48 kHz when 48k or 96k is selected.  
Use the supplied power cable to connect the IF-  
AE8HR to the power supply. Always ensure that  
your power supply matches the requirements marked  
on the rear panel of the unit. If you are in any doubt,  
consult a qualified electrician.  
C WORD SYNC OUT (HI Fs)  
This BNC connector outputs a high-frequency word  
clock: either 88.2 kHz when 44.1k or 88.2k is  
selected, or 96 kHz when 48k or 96k is selected.
