3.4.3 Combined Use of XLR and DB25 Cable sets
The figure below illustrates a “mixed mode” configuration, where the AES16 is connected to an Apogee AD16X
16-channel Analog-to-Digital converter and to some other 8-channel Digital-to-Analog converter. This represents a
unique situation, in that the AD16X will utilize all 16 available input channels while connected to a single I/O port
of the AES16, while only 8 output channels will be available to the D/A converter.
The AD16X is connected to the AES16 via our CBL-AES1603 cable, which is specifically designed to
accommodate the Apogee 16-channel converters through their D-Sub port. I/O Port B in this example is connected
to an 8-channel D/A converter using our CBL-AES1604 cable with standard XLR connections.
It is critical that the AES/EBU inputs on the CBL-AES1604 cable NOT be connected to any external device
since these inputs are connected electrically to inputs on I/O Port A. Doing so will degrade the quality of the
digital signal received on I/O Port A. Consequently, this configuration is limited to 16 input channels and 8
output channels, rather than the 16 in and 16 out which are possible with other cable set combinations.
ƽ
PLEASE NOTE: Since the CBL-AES1605 supports input and output signals through a single connector, it is not
advisable to use the CBL-AES1605 with the CBL-AES1603 at the same time.
In this example, the AES16 will function as the system clock master, with the Apogee AD16X and 8-channel D/A
converter acting as clock slaves. As shown, the word clock output available on the BNC connection of the CBL-
AES1604 cable is connected to the word clock input on the Apogee AD16X. The D/A converter can receive its
clock via the AES/EBU signal from the AES16, or from the word clock out of the AD16X. If the word clock is used,
a connection from the AD16X word clock out to the D/A word clock in is required.
I/O Configuration Jumper Settings
When using the CBL-AES1603 connected to an Apogee 16-channel converter, the associated I/O port on the AES16
must be set to 8 CHNL mode. For this example, set the jumper for I/O Port A to 8 CHNL mode. Confirm that the
I/O Port B jumper is in the factory default 4/4 CHNL mode. See Section 12.1 I/O Configuration Jumpers for more
information.
AES16 Clock Settings
To setup the AES16 as the system clock master, set Sample Clock Source in the Lynx Mixer Adapter window to
Internal.
