Digital HD Video Camera Recorder
HVR-A1N
Expanding New HD Shooting Opportunities with an Unprecedented Level of Compactness and Mobility
– the HVR-A1N HDV 1080i Camcorder
In response to the ever-increasing demands for HD program production, Sony launched the new high-definition recording system adopting the HDV 1080i specification of the
HDVTM format – the HVR-Z1N camcorder and HVR-M10N VTR – in 2004. Upon that introduction, these products have rapidly acquired a huge reputation from a wide range of customers due to their outstanding picture quality, stunning performance, and cost-effectiveness. Sony has now expanded the HDV line-up by introducing the HVR-A1N camcorder to meet further evolving needs for HD acquisition.
The HVR-A1N is an extremely compact and lightweight handy-type camcorder, ideal for applications where space is at a premium or extreme mobility is required. This camcorder is equipped with a newly developed 1/3-inch type, 2.97-megapixel (total) CMOS sensor and an all-new Enhanced Imaging ProcessorTM that optimizes the performance of the CMOS sensor, providing outstanding high-definition picture quality.
In addition to HDV 1080i recording and playback, this camcorder offers the DVCAMTM/DV recording and playback capabilities that are provided on current Sony DVCAM models.
A down-conversion capability of its 1080i recordings is also provided for a flexible choice of production systems in HDV, DVCAM, or DV format.
Furthermore, the HVR-A1N incorporates a variety of convenient and professional features such as XLR audio input, time code capability, various automatic shooting modes,
and still picture recording.
Available at an extremely affordable price, the HVR-A1N will be another powerful option for HD field acquisition by all video professionals, bringing further broadened shooting opportunities.

Compatible with Existing and
New DV Videocassette Tape
As a member of the proven DV family of formats, the HDV format has, from the outset, been developed for compatibility with all grades of DV videocassette tape. This allows operators to use high-grade DV videocassette tapes for applications where high robustness is critical, or consumer-grade videocassette tapes for more economical operations. For heavy-duty applications, a new high-grade mini cassette tape has been developed; the DigitalMasterTM PHDVM-63DM. This tape is compatible with the HDV, DVCAM, and DV formats.
Long Recording Time
The HDV format adopts the same track pitch and tape speed as the DV format, thus offering the same recording time
– a maximum of 63 minutes when recording on a DigitalMaster mini cassette tape.
