Audio Processing and Signal Monitoring cont'd...
Audio Signal Monitoring
Deva Broadcast's DB7012 is a DAB/
DAB+ monitoring receiver meeting
the ETSI EN 300 401 DAB standard.
It offers support for programmeassociated data at standard and
variable bitrates and automatically
displays live metadata.
Leader Electronics LT4611 is a 1U
full-rack-width generator producing
audio word-clock signals, analogue
video sync and SMPTE ST 2059-2
profile. It is designed for use in both
SDI and IP infrastructure. As well as
providing both a 10 GbE and 1GbE
PTP interface, the LT4611 comes as
standard with three independent
synchronised analogue black and burst
outputs.
A stay-in-sync function maintains
signal phase when GPS reference is
lost and a slow-lock function reduces
quality-of-service issues that occur
when genlock is restored. Audiospecific option LT4611-SER23 can
output a 48 kHz AES/EBU signal
synchronised with the video stream.
This option can also generate AES/EBU
silence.
Lindos' MS20 is a combined audio
oscillator and analyser. Designed
both for system testing and lineup, it incorporates a 4 Hz to 40 kHz
digitally
synthesised
generator,
stereo PPM, balanced/unbalanced
converter, stereo microphone preamp, headphone amp, and a level
converter. Sequenced measurements
can be made automatically and the

TSL Products SAM-Q-SDI audio monitor

results presented on unit's OLED or an
attached PC.	
NTI Audio's DR2 is a handheld
instrument offering a wide range of
audio test signals. It also supports
surround-sound
test
sequences
for verification and adjustment
of Dolby Digital, Dolby E and DTS
installations. The internal clock
generator can be synchronised to
AES3, DARS, word clock and incoming
video. Measurement of channel
transparency, channel propagation
delay and sample frequency is
supported.
NTI Audio DR2
offers a wide
range of audio
test signals

The generator has transformerbalanced AES3 and S/PDIF outputs,
as well as TOS-Link and ADAT outputs.
User waveforms can be loaded via USB
into the internal flash memory.

Lindos MS20 combined audio oscillator and analyser

Rohde & Schwarz' UPV is claimed
to allow a wide variety of audio signal
measurements including frequency
response
measurement,
total
harmonic distortion display, spectrum
display and analysis of digital
interfaces. An internal generator
to create a wife range signals, from
sinewave and noise up to multisinewaves. An integrated control PC
makes the unit easy to transport and
operate. Scalable graphic windows can
be combined and moved around on
the screen. Results can be displayed in
real-time for one or both channels.
The UPV can optionally be expanded
to handle up to 16 channels. Results
can be read off using vertical and
horizontal cursors. Limit lines or
stored measurement results can be
superimposed.
TSL Products' SAM-Q-SDI audio
monitor is designed for use with
SDI, AES and analogue audio

Operators can choose versions with
either eight or 16 level controls, both
with an independent master level
control and instant mute capability
and push-for-solo capability. Individual
OLEDs show status, presence metering
and channel name. The channel
name can be manually edited or
automatically read from a network
connected router. Multiple units on
the same network can be controlled
via an IP interface that supports
fast conīŦguration with role-based
authentication to protect critical
setups.
WorldCast
Systems'
Audemat
DAB Probe is designed to monitor
DAB signal quality and service
continuity at a transmitter site or
in a coverage area. It can perform
remote monitoring of a set list
of channels and allows users to
verify the conformity of their DAB
network to relevant legislation and in

sources. Sources, modes and front
panel functions can be restricted to
streamline control and minimise user
error. Options include MADI support
and loudness monitoring.
Wohler's iAM-MIX provides audio
signal monitoring with instant access
to signals, user-definable presets of
any individual signal source or a mix
of sources for monitoring and mixing.
Signal options include the latest IP
formats: SMPTE 2110, SMPTE 2022,
Ravenna/AES67 and Dante.

accordance with their own specified
parameters. Compatible with single
and multiple frequency networks,
the probe includes an IP control
interface. Supported features include
alarm notification by email or SNMP
traps. The unit is equipped with a
telemetry board and audio output
connectors. Software tools allow signal
and content analysis with impulse
response representation, TII, audio or
ETI recording.
