BVM-A Series
Broadcast and Professional Monitors
Sony now redefines its decades of professional monitor experience with the introduction of a
new family of BVM Series monitors. The BVM-A Series of digital monitors, with a number of
impressive enhancements, has been designed to surpass the conventional concepts of existing
high-grade CRT monitors.
Positioned as a successor to the market-acclaimed Sony BVM-D Series, the BVM-A Series
– as an industry first – presents a full and consistent line of master-grade CRT monitors.
The BVM-A Series monitors are offered in four different CRT sizes – the 32-inch

and 24-inch
*

models with 16:9 aspect ratios, and the 20-inch
*
3
and 14-inch
*
4
models with 4:3 aspect ratios.
All four monitors support multi-format input, accepting a range of SD and HD signal formats,
with the added capability of dual-link HD-SDI input to monitor top-quality images up to
1080/50i and 1080/60i 4:4:4 RGB

While inheriting the modular design concept from its predecessor BVM models, a thorough
review of its input boards has been conducted. This has resulted in a simplified board lineup
that makes input configuration easier, while also offering optimized cost-per-input value. All
BVM-A Series monitors use the same optional input boards, so they can be effectively shared
between monitors when the need arises

The BVM-A Series also incorporates an all-new Ethernet™–based control system, allowing standard
network cables and hubs to be used for easy configuration, high reliability, and high communication
speed. And for monitor setup and control, the same logical menu structures and Auto Setup
capabilities have been retained from its BVM predecessors, further facilitating system setup.
Designed to meet the critical needs of today and tomorrow, the BVM-A Series is the choice for
any high-grade monitoring application in studio production, post-productions, telecine and
broadcast operations.

A Full Line of Master-grade
Monitors
The BVM-A Series of monitors comprises four models – the
32-inch BVM-A32E1WU*

with a 16:9 aspect ratio, and the 20-inch BVM-A20F1U*3and
the 14-inch BVM-A14F5U*

with a 4:3 aspect ratio. All four
monitors have been developed in line with Sony’s evaluationgrade monitor standards, providing the high resolution and
wide and natural frequency response required for master
monitoring applications. This consistent image quality is a
significant benefit over conventional monitor product lines,
which can offer lower specifications for smaller screen sizes.

Flat surface HR Trinitron
To provide the highest possible picture quality, all BVM-A
Series monitors are equipped with CRTs manufactured by
Sony, using either SMPTE-C or EBU standard phosphors. Flat
surface 16:9 aspect HR Trinitron CRTs have been exclusively
designed for the BVM-A32E1WU and BVM-A24E1WU models.
Faithful Color Reproduction
The BVM-A Series monitors are designed to provide most accurate
phosphor chromaticity, white uniformity, and color temperature,
thereby achieving extremely faithful color reproduction.
Stable Color Temperature
The internal beam current feedback circuit equipped on the
BVM-A Series monitors maintains a constant color
temperature over a long period of time.
Multi-format Signal Support
With the appropriate input boards installed, all BVM-A Series
monitors support a spectrum of SD and HD signals with
frequency responses ranging from 15 kHz to 45 kHz
(horizontal)/48 Hz to 60 Hz (vertical). Input signals are
scanned on the CRT raster at their native frequencies and
native line counts, with no scan conversion processes involved.
Dual-link HD-SDI
To be prepared for the fast-paced changes in video
production, the BVM-A Series monitors offer dual-link HD-SDI
capability, meeting the SMPTE 372M standard. Using two HDSDI connectors in a pair, the BVM-A Series allows a variety of
digital 4:4:4 HD signals to be accepted in both GBR and
Y/PB/PR signal formats.
