Panasonic AG-7500 - Key Features and Enhancements

FEATURES >
1. Amorphous heads and high quality picture
Picture quality has been improved by the use of the S-VHS
system and the amorphous heads. Resolution of over 400
lines and less noise are realized in the following
conditions.
eFM
carrier
frequency:
White
peak;
7
MHz
Sync tip; 5.4 MHz
einstallation
of
sub-emphasis
circuit
eWhite clip level: 210 %
eUse of S-VHS tape
2. Use of digital YC separator circuit
ePerfect YC separation is possible even in noncorrelating
portions.
Because of burst PLL system, non-standard signals can
be separated, too.
®As
digital
signals
are
process,
YC
can
be
separated
with
small
temperature
or
characteric
changes
by
a
stable
operation.
3. Time Code Editing
The unit allows the execution of time code editing when
this
unit
is
connected
to
the
AG-A750
Editing
Controller.
Synchronization is also possible at the Edit IN point by the
Capstan Override Connector.
4. High precision linear audio editing timing
When
insert
or
assemble
editing,
itis
possible
to
edit
at
the
linear
audio
editing
timing
of
+1
frame
with
respect
to
the
video
recording
timing.
(When
using
AG-A750.)
5. Automatic back space function
By the automatic back space function, video and audio
data without blank portions can be recorded by splicing.
6. H-aligned framing servo
Sometimes, when editing video signals conforming to the
CCIR
standard,
frame
phase
misalignment
or
horizontal distortion occurs between adjacent edited
portions. This unit employs a framing servo to align the
frames, thus eliminating such errors at the edit start and
end points.
7. Flying erase-based editing
The adoption of a “rotary erase head” makes it possible to
achieve top-grade electronic editing without noise or
frame mis-synchronization.
8. Dual audio channel-Dolby* NR system
Because there are two normal audio tracks, stereo or
bilingual programmes can be recorded and played back.
The sound quality is further improved due to the built-in
Dolby NR system.

Licensing Corporation.

9. Recording and playback of Hi-Fi sound
(HD sound) and assemble editing
You can record and play back HD Sound even without a
video input signal. You can also independently record a
total of four channels, that is, HD Sound (CH1/CH2) and
Normal Audio CH1/CH2.
10. JOG/SHUTTLE search function using dial
A programme segment on the tape can be rapidly and
accurately found by using the SHUTTLE search in which
the tape speed is varied between 0 and 10 times the normal
speed, or the JOG search in which the tape speed is varied
in accordance with the rotational speed of the dial.
11. Field still function
This function provides attractive still pictures with minimal
jitter.
12. Rack mounting possible due to front
loading
The unit is a cassette tape insertion type employing front
loading, hence it can be easily installed in an IEC standard
19-inch rack.
13. Editing and dubbing connectors
Special connectors designed for dubbing provide
improved picture quality when dubbing or editing
between video recorders.
14. Time code recording and playback
The EBU time code can be recorded and played back on
the audio CH2 track.
15. Independent editing
When the AG-7500 is used independently as an editor
and the edit start and end points are memorized in the tape
counter, editing automatically takes place between those
points.
16. System editing
An editing system can be configured by connecting the
AG-7500 to an Editing Controller.
eUp to three source (playback) units can be connected
simultaneously by using a Remote Search Controller
(NV-A505, option).
eit is possible to configure a system by connecting the
unit to the AG-A750, AG-A650, NV-A500 or NV-A960
Editing Controller (options).
