7500NB Architecture

7500NB AES Audio Systems are built around a 256x256, two bay, 12RU
matrix. The 7500NB 256x256 uses one matrix and the 7500NB 512x512 uses
two matrices connected together at the backplanes with expansion con­nector modules. The 7500NB 1024x1024 uses eight matrices connected
together.

Matrices are populated with crosspoint modules, input modules, output
modules, and matrix controller modules. synchronous and asynchronous
input and output modules are available. Both types of modules can be
placed in the same matrix. The synchronous modules can be configured to
allow an asynchronous signal to be passed through an input or an output.

The two bay, 12RU matrix uses four input modules, four output modules,
and eight crosspoint modules for a fully configured 256x256 system. Each
bay of the system contains a slot for a matrix controller and a power supply.
The slot locations for the modules are shown in Figure 1-3. The empty slots
are used for crosspoint modules in expansion systems larger than 256x256.

System Level Architecture

Two of the two bay, 12RU matrices are connected using expansion connec­tors to create a fully configured 512x512 system. The system uses eight
input modules, eight output modules, and thirty-two crosspoint modules
as shown in Figure 1-3. The top bay is always used for inputs 1-128, the
second one for inputs 129-256, the third for 255-384, and the fourth bay is
used for inputs 385-512.

Communications between matrices and control systems use either
Ethernet or Global Serial Channel (GSC) interfaces. The Encore Control
System requires an Ethernet connection and Series 7000 requires a GSC
connection. Communications between matrices in expanded systems
requires Ethernet.

7500NB Ethernet

Ethernet is required for communication among the Encore Control Frame
and 7500NB matrices. Ethernet is also required to communicate among
matrices in 7500NB systems larger than 256x256.

Ethernet communications can be established between the Encore Control
Frame and a 7500NB matrix using either

2. One connection can be used as a primary connection and the other can

be used as a redundant connection. See Figure 2-10
The multicast signals from the 7500NB matrices are routed through a

managed Ethernet switch. Using the software and instructions that come
with the managed Ethernet switch, Virtual Local Area Networks (VLANs)
can be created to manage the communication between matrices, the Encore
Control Frame, and other equipment connected to the switch. The
managed switch must support IP multicast with Internet Group Manage­ment Protocol (IGMP).

controlled by a Series 7000 Control System. Dedicated Ethernet Switches
are used to communicate between the matrices. One Ethernet Switch is
required for each set of up to four matrices. The switches do not have to be
in the same rack as the matrices and the standard cable length restrictions
of 100 m (328 ft) apply.

References

7500NB AES Reference

7500NB systems have dual AES reference inputs. Two AES sync reference
loop-thru inputs provide a 48 kHz AES formatted signal upon which the
router bases its re-synchronization to frame and block boundaries. This
signal is assumed to be present for the router to be called synchronous. Two
inputs are provided for redundancy. In the event of loss of one AES refer­ence the router will default to the second reference if one is present, other­wise, it will default to asynchronous operation.

In systems with mixed module types (async and sync input and output
modules) the reference signal is required for the synchronous modules to
function properly. In systems that contain only asynchronous input and
output modules the reference signal is not required.

Figure 2-16 shows the flow of the AES reference signal. All signals have to

be terminated at the end of the flow . Cables must be as short as possible and
each cable pair must be the same length. Input Signal 1 and Input Signal 2
is one cable pair . Output Signal 1 and Output Signal 2 is another cable pair.

Power

AC Connections

Frames may be powered using either an AC power source, or a 48V DC
power source. It is also possible to cable a matrix using an AC power sour ce
and a 48V DC power source at the same time. If a matrix has both AC and
DC power sources available it will use whichever power source can meet
its power level demand. So if the AC power source fails then the DC power
source would feed the matrix, and if the DC power starts to fall the AC
power would feed the matrix. AC and DC power sources ar e kept separate
with no feedback, so the AC power source will not char ge batteries used in
a connected DC power source.

The 7500NB 256x256 and the 7500WB 128x128 come with one power
supply . The 7500WB 256x256 comes with two power supplies. Redundancy
is provided by adding additional power supplies.

48V DC Connections

WARNING Do not apply a 48V DC power source until all 48V DC connections on the

7500NB 48V DC

The 7500NB 48V DC connection requires 12 AWG (3.31 mm2) wire and a 3­pin female terminal block connector. See Figure 2-19.

Configuration

Matrix configuration procedures are dependent upon how the matrix fits
within its resident system and how that system is controlled. If you are
using a Series 7000 Control System you will generally need to follow the
instructions for matrix configuration found in the Series 7000 Configuration
Manual. In some cases, however, you must use 7500-specific settings. This
section highlights those distinctions.

7500NB Configuration

The 7500NB matrices can be controlled by the Series 7000 Control System.

Series 7000 Control of 7500NB

Section 3

The Matrix Controller in the 7500NB matrix communicates with the MCPU
in the Series 7000 Control System. The configuration of the Matrix Con­troller is handled by the Series 7000 Configuration Editor GUI. The
7500NB-specific settings for the Matrix Controller are applied during the
Configured Node Controller (CNC) and Physical Matrix procedures. A
separate Configured Node Controller record is required for each 7500NB
matrix in the system. In a single system, that has multiple 7500NB matrices,
all of the CNCs for the 7500NB matrices must be combined into a single
Physical Matrix. For example, a system that contains a 7500 NB 256x256 (1
matrix frame) would be configured with 1 CNC and 1 Physical Matrix. A
system that contains a 7500 NB 1024x1024 (8 matrix frames) would be con­figured with 8 CNCs and 1 Physical Matrix.

Figure 3-2. AES Output Attributes for Outputs Window

This window allows the outputs to be set individually or in groups. If
you were configuring a matrix that contained Asynchronous Output
modules then you would use the check boxes under

Asynchronous Output

7500 Series Instruction Manual 3-3

Section 3 — Configuration

to set groups of 64 outputs to Asynchr onous. If you were configuring a
system that had some Asynchronous Input modules (one or just a few)
and wanted to assign a few Outputs on a Synchronous Output module
to pass asynchronous signals, then use the individual settings under
the

ASync column.

Outputs can be assigned
individually, in groups, or by using the

Soft Mute/No Soft Mute

Soft Mute/No Soft Mute and 20/24 Bit Processing

All buttons.

The Soft Mute/No Soft Mute attribute is a soft mute or alignment of one
signal’s amplitude to another signal’s amplitude at switching. This soft
mute prevents a crack or pop at switching.

20/24 Bit

The 20/24 Bit attribute determines how the signal bits are processed. A
signal has 24 bits with the last four bits designated as auxiliary (AUX)
bits.

In

20 bit mode the four AUX bits pass through the router unaffected by

any processing. If left and right channels are swapped, the four AUX
bits stay in the same place. If the signal is muted, the four AUX bits are
not muted.

In

24 bit mode the router will treat the four AUX bits as though they are

part of the audio data. If left and right channels are swapped, the four
AUX bits will swap locations. If the audio is muted, the four AUX bits
will be muted.

Functional Description

Matrix Controller

The Matrix Controller (MC) modules are used in 7500 Series models. MCs
are designed to work in pairs (one primary, one backup) to provide failure
resistance. The primary MC provides all required functions; the backup is
ready to take over should the primary unit fail. Control logic facilitates
orderly change of control between the two modules and ensures that only
one module at a time controls the external serial busses.

Control consists of messages created to set matrix crosspoints, and the
return from the MC contains true tally status back to the control system.

The MC module can be inserted into a powered frame. To ensure that the
system power supply is not disturbed, a pre-charge resistor is connected in
series with one of the rear connector pins. The corresponding pin on the
backplane connector is longer than any of the other power pins. This allows
the pre-charge pin to make connection before the others.

Section 4

A 25-pin D connector labeled
optional interface.

A SMPTE Vertical Interval Time Code (VITC) reader is used to allow pre­loaded events to be triggered on a particular SMPTE frame number. This
signal must be applied to the single coax vertical reference input.

Vertical interval reference is still required for crosspoint switching tasks.
This is an analog video input which can be NTSC or P AL. This input is pr o­cessed to extract vertical sync and odd/even field (if any) information. Pre­defined progammable logic device (PLD) logic is used to create a switching
strobe that is offset into line 10 for NTSC or line 6 for PAL. A video presence
detector interrupts the processor if the video refer ence is missing. If this ref­erence is missing then a fake sync is generated at a default asynchronous
interval.

Thermal Control Module Reset 7500WB 256x256

The Thermal Control module monitors the temperature inside the matrix.
It controls fan speed and will shutdown the matrix if a critical temperature
condition occurs (temperature in excess of 80° C, 176° F). This is a fail-safe
feature. If a shutdown does occur all modules within the matrix should be
inspected. Once the cause of the critical temperature condition has been
identified and corrected, the Thermal Control module must be reset. Refer
to Figure 5-5.

To Reset the Thermal Control Module

1. Remove cover screws. Set cover aside.

2. Slide the module out at least one half inch to unseat the module.

3. Reseat the module into the frame.

4. Replace cover and secure with screws.

Physical Matrix. Inputs and Outputs within
a Virtual Matrix need not be contiguous.
Only Destinations with Outputs in a given
Virtual Matrix will be able to directly, with­out using a TieLine, access the Sources with­in that Virtual Matrix. As an example of their
functionality , V irtual Matrices, working with
control Levels, allow you set up selected In­puts and Outputs to handle R, G, B video sig­nals by assigning each component to its own
Virtual Matrix. Extending this example, if
you assign the R, G, and B Virtual Matrices to
the same control Level, they will always
switch together as a married block; if you as­sign the R component Virtual Matrix to one
Level, and the G and B Virtual Matrices to a
second Level, you would then be able to
break the R component away from the other
two by selecting to control only the R V irtual
Matrix associated Level at the control panel.
