2.5 Applications
2.5.1 Analog inputs & outputs connections
Inputs connections
The IN1L, IN1R, IN2L and IN2R jumpers select the impedance value for each input: a jumper ON
selects a 600 Ω input impedance. When OFF the impedance is >10 kΩ.
Outputs connections
The equipment connected to the UAP-711i or UAP-712i is supposed to be high impedance.
When the equipment connected to UAP-712i has an input impedance equal to 600 Ω, the power rating
allowed for one slot is exceeded. In that case two slots are required for one UAP-712i. The single
module UAP-711i will support 600 Ω loads without power limitations.
2.5.2 Digital inputs & outputs connections
When used with an AES3-id 75 Ω rear panel (Symphonie R-AX), switches SW4, SW51, SW53, SW61,
SW63, SW71, SW73, SW81, SW83, SW91 must be set on the A75 position.
When used with an AES3 110 Ω rear panel (Quartet A110 or Symphonie R-A110), switches SW4,
SW51, SW53, SW61, SW63, SW71, SW73, SW81, SW83, SW91 must be set on the A110 position.
2.5.3 Synchronization
When the AES ouputs are used, an external reference signal may be required to synchronize these
digital outputs.
The detection of the reference standard is automatic. An AES3 digital audio reference signal connected
at the AES Sub-D has a higher priority than any reference signal connected to the BNC jack.
In stand-alone mode the REF led, when green, indicates compatibility between the sync signal and the
AES output-sampling rate selected. It will be orange if the AES output signals are not synchronized to a
reference signal.
When used in conjunction with a video processor, the reference source is the video module that delivers
a 27 MHz reference signal (via the ABUS front panel connector). The REF led will be green to indicate
the validity of this 27 MHz, orange when it is not valid but with an external valid reference signal
connected at the rear, and red in other cases.
The relative phase between external sync signal 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.
RA-110 rear panel The AES 110 Ω Sync input is located on "AES" Sub-D socket. The switch "LD110"
must be set on the LOZ position to properly terminate the line. Other syncs are
connected on BNC jack "REF.IN". The switch "LD75" must be set on the LOZ
position to properly terminate the line. The second BNC jack 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.
RA-X rear panel
The sync signal must be connected on BNC "REF.IN". The switch "LD75" must be
set on the LOZ position to properly terminate the line.
When used in a Symphonie frame, the module 75 Ω ? ? r eference input can be connected to the global
reference signal (video or Word Clock only) instead of the BNC REF.IN. It is done by sliding LK1 to
position 1-2 (GLOBAL) on the rear panel and SW4 to position A75 on the module, regardless of the rear
panel
