When you
introduce a new model to succeed the most respected line of portable recorders
in audio history, it had better be something special. It must be more than a
new recorder - it must be a significant
improvement, ATR-700 is both.
For more
than 20 years, Ampex 500 and 600 series recorders have distinguished themselves
under the most demanding conditions. Long regarded as the professional's choice
for reliability in the field, their reputationfor ruggedness and performance
has made them the standard of excellence by which other portable recorders are
measured. Through the years, progressive generations of these solid machines
have proved themselves around the world and in every conceivable professional
application, from on-location sound recording for motion pictures to studio
recording and on-the-air broadcasting.
ATR-700 for
the audio pro who needs a recorder he can trust or the institution demanding
professional performance.
Here's a
machine with concert hall quality in a road show package. It fils the need for
more versatility and built-in convenience with many standard features that
either aren't available or cost extra on other compact recorders. It's a
professional in every respect - as a portable broadcast recorder, editing
recorder, or remote recorder.
Every ATR-700 includes 2-channel electronics.
So, if you order a single-track machine and develop requirements for 2-channel
capability, simply plug in the appropriate heads. Head stacks are precision
manufactured and offer plug-in flexibility to permit individual replacement and
configuration changes. And they're located for easy access, too.
The capstan servo D.C. motor is of the direct
drive type, providing the advantages of greater torque with improved
operational control and speed accuracy.
Pick the speed pair that
best suits your needs 3¾ and7 ½ or 7½ and 15 ips. No matter which version you choose, you get added
flexibility and command with the built-in variable speed control.
A universal power supply makes the ATR-700
truly cosmopolitan. A voltage selector permits operation on AC power anywhere
in the world. The optional portable case lets you take it with you - or use the
rack mount adapter for easy installation in standard 19-inch racks. Precision
operation is assured in both vertical and horizontal positions.
Electronic
motion sensing affords safe and rapid transition between operating modes. You
can move from shuttle speeds to playback and cice versa without touching the
stop button.
Synchronous
reproduce is standard. This feature lets you record a second channel in sync
with the sound on the forst channel.
Automatic
shut-off is actuated by the tape tension arm, and a cue control permits manual
defeat of one of the automatic tape lifters for monitoring at shuttle speeds.
Separate
switches are located on the front panel for bias, equalization and reference
level, so you can maximize performance with the professional tape of your
choice. An edit button permits spilling tape in playback to simplify editing
operation.
Three
reel sizes can be used with the ATR-700, and the front panel reel selector
gives proper tension for 5" / 7" and 10½" reels
Additional
features help to make ide easier, such as non-glare, back-lighted VU meters,
balanced mic input with switchable 20 dB attenuator, and a bult-in 4-in, 2-out
mixer with master gain control. A pause
button provides added cueing flexibility and quickstarts, while the
pinch roler automatically swings away when in "stop" mode to allow
easy threading. Modular design with plug-in PWA's permits ready acces to vital
electronics and greatly simplifies mintenance. For extra convenience, an
extender board with integral test points is included as standard equipment.
Designed in versatility also means reliable operation under a wide range of
environmental conditions - to meet the needs of users with special requirements
or tough field applications. ATR-700 has the personality of a "seasoned
pro".
