The following caution statements identify conditions or practices that can
result in damage to equipment or other property
Use correct power source
— Do not operate this product from a power sour ce
that applies more than the voltage specified for the product.
Use correct voltage setting
— If this product lacks auto-ranging power supplies, before applying power ensure that the each power supply is set to
match the power source.
Provide proper ventilation
— To prevent product overheating, provide equip-
ment ventilation in accordance with installation instructions.
Use anti-static procedures
— Static sensitive components are present which
may be damaged by electrostatic discharge. Use anti-static procedures,
equipment and surfaces during servicing.
7500 Series Instruction Manual xi
Do not operate with suspected equipment failure
— If you suspect product
damage or equipment failure, have the equipment inspected by qualified
service personnel.
Ensure mains disconnect
— If mains switch is not provided, the power cor d(s)
of this equipment provide the means of disconnection. The socket outlet
must be installed near the equipment and must be easily accessible. Verify
that all mains power is disconnected before installing or removing power
supplies and/or options.
Route cable properly
— Route power cor ds and other cables so that they ar not
likely to be damaged. Properly support heavy cable bundles to avoid connector damage.
Use correct power supply cords
— Power cords for this equipment, if pr ovided,
meet all North American electrical codes. Operation of this equipment at
voltages exceeding 130 VAC requires power supply cords which comply
with NEMA configurations. International power cords, if provided, have
the approval of the country of use.
Use correct replacement battery
— This product may contain batteries. To
reduce the risk of explosion, check polarity and replace only with the same
or equivalent type recommended by manufacturer. Dispose of used batteries according to the manufacturer’s instructions.
Troubleshoot only to board level
— Circuit boards in this product are densely
populated with surface mount technology (SMT) components and application specific integrated circuits (ASICS). As a result, circuit board repair at
the component level is very difficult in the field, if not impossible. For warranty compliance, do not troubleshoot systems beyond the board level.

Regulatory Notices
Certifications and Compliances
FCC Emission Control
This equipment has been tested and found to comply with the limits for a
Class A digital device, pursuant to Part 15 of the FCC Rules. These limits
are designed to provide reasonable pr otection against harmful interference
when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not
installed and used in accordance with the instruction manual, may cause
harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which
case the user will be required to correct the interfer ence at his own expense.
Changes or modifications not expressly approved by Grass Valley Group
can affect emission compliance and could void the user’s authority to
operate this equipment.
Canadian EMC Notice of Compliance
This digital apparatus does not exceed the Class A limits for radio noise
emissions from digital apparatus set out in the Radio Interference Regulations of the Canadian Department of Communications.

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.

7500NB systems can be expanded in increments of 64 inputs/outputs to as
large as 1024x1024. They are assembled using standard Grass Valley router
frames, distribution amplifiers, Ethernet switches, and in some cases
custom cables. Contact Customer Service for specifications and ordering
details. Table 1-1 shows the number of crosspoint modules required to
create configurations up to 1024x1024.Table 1-2 and Table 1-3 shows the
number of input and output modules needed to create configurations up to
1024x1024.The number of input modules needed is affected by how many
outputs the system contains.

The 7500WB 256x256 matrix frame is configured with a Controller module,
two Power Supply modules, eight Input modules, eight Crosspoint modules, eight Output modules, a two-piece backplane, an interconnect and an
optional monitor module. The router has two Controller module slots and
four Power Supply module slots to allow for redundancy. See Figure 1-6.
The 7500WB 128x128 matrix frame is configured with a Controller module,
one Power Supply module, four Input modules, four Crosspoint modules,
four Output modules, a backplane, an interconnect, a DC Distribution

module slots and two Power Supply module slots to allow for redundancy.
See Figure 1-6.
Inputs are routed by the Crosspoint modules to the Output modules to
ensure that all Inputs are available to all Outputs. See Figure 1-7 and
Figure 1-8 for the signal flow. Table 1-4 shows how many Crosspoint,
Input, and Output modules are needed to create configurations in a
7500WB 256x256 from 32x32 to 256x256. Table 1-5 shows how many Cros-
