Audio Monitor
The LV5838 is an audio monitor for audio console and master
monitoring. It measures audio signals that are embedded in
3G, HD, and SD-SDI signals and AES/EBU signals.
The LV 5837 is an audio monitor designed for use with audio
console and master monitoring.It measures AES/EBU audio
signals.
It can display loudness measurements, level meters, Lissajous
curves, surround sound fields, and audio status independently
or in combination.
All errors and events can be logged with local time information
or time code information that is embedded in video signals.
Logs can be stored in external storage media.
FEATURES
• Equipped with 8 connectors (16 channels) of AES/EBU signal inputs
The LV 5837 and LV5838 is equipped with 8 BNC connectors (16
channels).
• Support for LPCM, Dolby-E, Dolby-Digital, Dolby-Digital Plus
LPCM audio is supported as standard. Dolby-E, Dolby-Digital, and
Dolby-Digital Plus can be supported with a Dolby module (a Dolby
option).
• Headphone output
A 3.5 mm mini jack is available.
• Support for various types of scales
The LV 5838 supports dBFS, Nordic, BBC, and DIN level meter scales.
The level scale for loudness measurements supports both
absolute values and relative values in reference to a target level.
• Wide variety of measurement features
1) Audio level meter and peak hold meter capable of showing
measurements for up to 16 channels simultaneously
2) Lissajous display capable of displaying Lissajous curves and
correlation meters of any two channels
3) Surround display capable of displaying Lissajous curves and
surround sound fields of adjacent channels
4) Status display capable of showing measurements for 16 channels simultaneously
5) Loudness measurement in two measurement modes of the
three available measurement modes: monaural, stereo, and
5.1 channel
6) Chart display capable of showing the change in the short-term
loudness values and integrated loudness values over time
7) Logging of integrated loudness values with local time and time
code information
8) Channel status analysis display
9) User bit display
10) Metadata analysis display for Dolby-E, Dolby-Digital, DolbyDigital Plus (Dolby option)
11) Synchronous measurement of audio signals with black burst,
tri-level sync, or CW signals received through the EXT REF
connector(LV 5838 only)
12) Amplitude measurement of signals received through AES/EBU
connectors (LV 5838 only)
• Loudness measurement on/off control from the external
control connector (LV 5838 only)
Signals can be applied to the external control connector to start
and stop loudness measurements and clear measurement results.
[ Video and audio signal measurement(LV 5838 only) ]
• Frame location when non-PCM data is detected
Indicates an error when the frame location is outside the specified
embedding range
• Error log with time codes
Error logs with auxiliary packet time codes
• Loudness measurement channel switching based on interstationary control signals
Supports loudness measurement channel switching based on the
audio mode of inter-stationary control signals
