SL Products, manufacturer of
surround sound microphones
and processing, audio monitoring,
control systems and power
management solutions for the
broadcast industry, is introducing
the new Surround Zone2 DAW
(Digital Audio Workstation) plugin and ST450 MKII Surround Sound
Microphone System at CABSAT
2014.
The SurroundZone2 plug-in
unlocks the information captured by
any of the SoundField microphone
systems, providing unprecedented
control over a wide range of
microphone parameters from
a single intuitive user interface.
The MKII version of the popular
ST450 battery-powered surround
microphone system delivers a
new mic pre design with improved
metering functions.
"The new SurroundZone2 plug-in
and the ST450 MKII microphone
system were developed based on
extensive industry feedback as to
what the professional production

community needs to better complete
broadcasts and programming,"
says Pieter Schillebeeckx, Product
Manager of SoundField for
TSL Products.
"The main focus throughout the
development of these
products was ease
of use across the
most popular Digital
Audio Workstations,
both from a usage
and a set-up
perspective."
The
new
SurroundZone2
plug-in rolls all the
functionality of the
original "Surround
Zone" and "SPS200
Surround Zone"
plug-ins into one.
At the same time
the new software
adds some exciting
new controls such
as "Snap Tilt" and
"individual polar
pattern control" for
the surround modes
SurroundZone2
supports Stereo
(Mono) and surround sound
formats including 5.0, 5.1, 6.0,
6.1, 7.0, 7.1 and SoundField's
proprietary B-Format (for SPS200

A-Format input only) outputs.
Available Controls include Input
and Output trims, Hi-Pass Input
filter, Mic Orientation: End-Fire
and Invert, Solo and Mutes for the
Individual outputs, Rotate, Snap
Tilt (individual front and rear tilt)
and Zoom, Individual Width
Controls and Individual Polar
Pattern Controls.

Plug-In Formats
The plug-in is available in
the following formats: AAX
Native and VST (both 32-bit
and 64-bit, for PC and Mac)
and AU (both 32-bit and
64-bit for Mac).

The new ST450 MKII further
reﬁnes the design of the electronics
in the original ST450 preamp
package. The new mic-pre design
allows for 3dB gain steps, replacing
the 6dB steps of the original, giving
operators the opportunity to more
accurately fine tune the gain
structure during capture. In addition,
the overall available gain has been
increased from 30dB to 42dB,
delivering more system headroom.
This is especially important for
location recordings of low level
sources. Finally, the seven-segment
bargraph meter now includes a
peak hold function for at-a-glance
tracking of signal overload.

SDI-Embedded Audio Interfacing Made Easy: NTP Technology
By Mikael Vest
Sales Director of NTP Technology

E

mbedding audio in the SDI
stream has been a practice
since the mid-1990s when the

Gigabit IP Ethernet plays a central role

SMPTE standardised the ﬁrst in
what is now a family of serial digital
interfaces.

In the early days, much of the
SDI content was interfaced via
devices such as Sony Betacam
video tape machines, the audio
being embedded with the video in
up to two groups of two AES/EBU
channels. Each AES/EBU channel
was allowed to be asynchronous to
the video signal.
The SMPTE standards for SDI
were gradually developed to support
high-deﬁnition and more recently 3
gigabits per second (3G) SDI.
The audio embedding capacity
was also increased to support
16 channels in HD and 32
channels in 3G.
This meets various needs for
audio interchange along the SDI
line including peripheral content
such as intercom channels.
Channel routing has become
a useful way to achieve
operational flexibility.
Also useful is the ability to support
multiple digital audio interfaces
for connecting the embedded
audio signal to the outside world.

Interfacing is typically via AES/
EBU, MADI, IP Ethernet Audio or
plain analogue.
Since the number of possible
embedded audio channels in an
SDI signal stream often is higher
than the number actually used even
in complex application, a router is
often used to select the required
channels for the particular audio
interface used.
This routing can be dynamic,
depending on the required workflow.
NTP Technology's Penta 720 SDI
I/O and router unit allows routing
directly between SDI embedded
audio channels and AES/EBU,
MADI, or Ethernet-based IP audio
interfaces, either at box level or
system level.
Each Penta 720 provides a total of
16 SDI input and output interfaces
with the option of interfacing IP
audio powered by Dante via a
standard gigabit Ethernet, a very
ﬂexible, efﬁcient and cost-effective
audio exchange system can
be established.
