1 General
1.1 Introduction
The ASD-711i is a high quality, 24-bit Analog to digital audio converter that allows conversion of
a stereo Analog audio signal to an AES/EBU type digital signal. The dual version, ASD-712i, is
fitted with two independent converters. The sampling rate can be set up to 96 kHz by an internal
clock, or by using an external reference signal. The internal digital EBU tone generator, enabled
from the card edge, facilitates alignment of audio levels. User set channel identification data may
be encoded in the AES/EBU status bits. The ASD-711i and ASD-712i are compatible with AES3
110 balanced and AES3-id 75 unbalanced audio standards.

2.5 Applications
2.5.1 Input connections
When one source equipment is connected to
one ASD-711i or ASD-712i, 600 termination
load can be selected: the corresponding jumper
IN1L, IN1R, IN2L, IN2R must be set on "ON"
position.
When source equipment are connected to
several ASD-711i or ASD-712i, if a 600
termination load is needed, it must be
selected on the last ASD-711i or ASD-712i. The
corresponding jumper IN1L, IN1R, IN2L, IN2R
must be set on "ON" position.
ASD-711i corresponds to only channel 1; ASD-
712i corresponds to channel 1 and 2.
Figure 9: Input connections
2.5.2 Output connections
When used with a 75 rear panel, switches SW1, SW2, SW11, SW21, SW12, SW22, SW13,
SW23, SW14, SW24 must be set on the A75 position.
When used with a 110 rear panel, switches SW1, SW2, SW11, SW21, SW12, SW22, SW13,
SW23, SW14, SW24 must be set on the A110 position.
2.5.3 Synchronization
A green Led (REF) on the front-end side of the board indicates when lit that the present external
sync is valid. If the sync signal is an AES or a Wordclock, the user has to select the same
sampling rate (in the FREQ menu) to get a valid sync. When the external sync mode is selected
and non-valid external reference signal is detected, this Led blinks. In external mode, the Led
stays off.
The relative phase between sync and AES samples is respected for any case except for mode
VIDEO/NTSC. For VIDEO/PAL mode, output samples are aligned with the start of the first line.
The setting of internal or external synchronization is made via the user's front interface or
remotely.
110 rear panel The AES 110 sync input is located on "AES" D-Sub socket. The switch
“LD110” must be set on the 110 position to properly terminate the line.
Other syncs are available on BNC jack "REF.IN". The switch “LD75”
must be set on the 75 position to properly terminate the line. The
second BNC jack "N/C" is lined to "REF.IN" input and may be used as
loop-through. For this conditional use, the switch “LD75” must be set on
the HIZ position.
75 rear panel All sync signal are available on BNC "REF.IN". The switch “LD75” must
be set on the 75 position to properly terminate the line.

2.5.4 0dBFS
The three switches “SW3”, “SW4” and “SW5” set the RMS value of sine wave to obtain 0dBFS
for a level adjustment set to 0dB.
2.5.5 GPI Outputs
Four open-collector GPI outputs (one for each channel) are available on the REM socket. No
current flows through one output pin when the corresponding Led is OFF (Analog signal present)
and each output sinks current if the Led is ON (absence signal or overload).
These outputs are inactive when the alarm are disabled (ALRM menu, OFF selection).

3.3 Menu introduction
Most ASD-711i or ASD-712i parameters are accessed and changed via an easy-to-use menu.
The flow chart of figure below outlines the entire ASD-711i or ASD-712i menu path. Each menu is
described throughout this section. The follow items should be remembered when accessing the
menu.
Automatic display turn off after 1-minute interval
If the menu is currently being accessed and no push-button has been pressed for 1 minute, the
ASD-711i or ASD-712i automatically turns off the display. A press on any push button [ + ], [ - ] or
[ SEL ] will turn on the display without any change on the current parameter.
Navigating through the menu
The front panel push buttons are used to navigate the menu. The following describes the function
of each push-button when navigating through the menu.
[ + ] Press [ + ] to move down in the menu or to increase the parameter value. For
example, if you are currently at I-1&2, pressing [ + ] will scroll downwards
through the selections I-1 and I-2.
Depressing [ + ] during an adjustment will increase the parameter value at faster
rate.
[ - ] Press [ - ] to move up in the menu or to decrease the parameter value. For
example, if you are currently at FREQ, pressing [ - ] will scroll through the
selections REF, TEST, MUTE and DITH.
Depressing [ - ] during an adjustment will decrease the parameter value at faster
rate.
[ SEL ] Changes to a menu parameter are stored immediately to non-volatile memory.
For example, after the L gain value has been set, press [ SEL] and the new
value is stored for the current format and ASD-711i or ASD-712i returns to
previous menu .
[ ESC ] If [ ESC ] is pressed after changes to a parameter, the parameter is reset to the
value it had prior to the change, For example, after changing L level, press [
ESC ] the previous value is reloaded and ASD-711i or ASD-712i returns to
previous menu. When on root menu, a press on [ ESC ] turns off the display.
Note: If the L and R values are different, the L value will be displayed after a L&R
selection. On the same way, the channel 1 value will be displayed after a I-1&2
or 0-1&2 selection.
