KEY FEATURES
Acappella
M ULT I - FOR M AT U T I L I T Y ROUTING S Y S T E M S
The Acappella multi-format utility
system of small, single- and mixed-
format routers is designed for a variety
of broadcast and production settings,
including small studios, sports arenas,
and space-constrained environments
such as mobile production trucks.
Grass Valley
™
products include a lineup
of routers that scale from a handful of
crosspoints to millions and that are the
most intuitive, most flexible, and least
power-consuming available.
The Acappella
™
multi-format utility
system of small, single- and mixed-
format routers is designed for a variety
of broadcast and production settings,
including small studios, sports arenas,
and space-constrained environments
such as mobile production trucks.
Only 1 RU in size, the Acappella line
system ranges from 8x4 to 16x16
models with up to four independently
controlled levels and offers single- and
select multi-format routing capabilities.
Its format support includes standard- and
high-definition (SD and HD) video and
AES/EBU digital audio.
An Acappella router comes ready to
operate right out of the box—just
plug it and you can get right to work.
It also supports Web browser-based
configuration for fast, easy customization.
And with its 14-inch (34.5 cm) depth, you
never have to reach deep inside the back
of a rack to change out a cable.
Designed to maximize uptime, the
Acappella router comes standard with
dual power supplies for full power
redundancy. Each power supply features
a removable IEC power cord connection
with integrated cord clamps to eliminate
accidental unplugging; the cord
connection also supports any AC plug
end available.
Acappella routers also feature a variety
of signal-processing capabilities,
including the unique ability to reclock
video at all standard data rates, including
1.5 Gb/s, and digital audio silence
generation when no input is available.
As easy to operate as it is to install, the
Acappella line supports local and remote
control panels, via a built-in Ethernet
connection. It also includes many unique
control panel operational modes—such
as destination gang, chop, panel enable,
and destination protect—necessary to
simplify and accelerate your workflow
and reduce mistakes.
The Acappella system features an RS-422
serial port, which uses the industry-
standard HX-TCI protocol for integration
with the Grass Valley Jupiter
™
router
control system and Series 7000 control
system, automation systems, and third-
party remote-control system.
Next-Generation Design
The next-generation design of the
Acappella system can keep you
productive and operational day in and day
out. Unlike other routers, the Acappella
router supports dual redundant auto-
ranging AC power supplies to maximize
uptime.

PRODUCT DATA SHEET

With a 14-inch (34.5 cm) depth, you
never have to reach between closely
stacked equipment in a rack to grab an
Acappella system cable. And should you
need to power off the router at night, it
will remember and initialize the previous
crosspoint configuration when turned
back on the next morning.
Inside, the architecture of the Acappella
system has several key advantages. Its
vertical input and output boards enable
low-cost factor y expansion of its base
model to provide the crosspoints you
need. This architecture also makes it
easy to add new features to future
Acappella routers.
The Acappella router also offers high-
performance digital video and audio
processing. Its video processing
features include automatic input cable
equalization as well as automatic output
muting when no input is present. It also
supports the reclocking of a data stream
at all standard data rates, including
1.5 Gb/s, eliminating the jitter associated
with long cable runs and previously
processed signals.
When this reclocking functionality is
active, Acappella routers automatically
adjust the rise times of digital data
to correctly match the SMPTE
specifications for both SD and HD data
rates. Acappella routers perform vertical
inter val switching and are configured to
switch at the proper horizontal line in
all cases for 525, 625, SD, HD, and the
different HD formats.
For digital audio, Acappella routers offer
synchronous switching at the sample
boundary to create a contiguous data
stream, eliminating any downstream
signal-processing issues. Unlike other
routers, they generate digital silence
when no audio is present; this unique
feature keeps downstream equipment
synchronized and eliminates unwanted
audio disturbances. They also support
sum, swap, invert, bypass, and block-
align modes.
Plug-and-Play Operation
An Acappella router comes ready to use.
In the few instances when configuration
is necessary, all you need to do is
connect a standard Web browser to the
router’s Ethernet interface—or use the
Grass Valley NetConfig application that
comes standard with the router.
Acappella routers feature built-in control
of up to four levels of 16 inputs and 16
outputs with a combination of either
local or remote control panels. You can
also deploy the Prelude control system
to support larger networks of Acappella
and Concerto
™
Series routing matrix.
Acappella routers use an Ethernet
interface to connect remote control
panels and additional matrices. In
addition to a local control panel attached
to the router frame, you can connect
multiple remote panels to an Acappella
system.
Panel Features Streamline
Workflows
Acappella system control panels have a
number of powerful features to speed
and streamline your workflows—and to
help prevent mistakes.
The destination gang mode, for example,
lets you send a single source to multiple
destinations with a single button
press, which is very useful for VTR
tape duplication and system-alignment
applications.
With the router’s chop mode, you
can automatically toggle between
two selected inputs; it’s a great
capability when you need to make
quick and simple level timing and phase
comparisons of input sources.
Meanwhile, the panel-enable mode of
the Acappella router quickly enables/
disables a panel from allowing source
takes. This mode provides an extra
measure of security from unintentional
button contact that can disrupt your
workflow or signal.
Acappella routers also feature a
destination protect mode, which adds
a level of security to your source-to-
destination connections. When in this
mode, it will ask an operator to confirm if
they want to make a particular source-to-
destination change and require removing
that layer of protection to effect the
change.
Acappella routers interface with the
Grass Valley Series 7000 system, Jupiter,
Prelude, and Encore systems. For
connections to third-party automation
and control systems, Acappella routers
have an RS-422 serial control port that
comes standard on every matrix. This
control interface port uses the industry-
known HX-TCI protocol to enable simple
plug-and-play automation control.
