CD-330 Professional 3-Head Stereo Cassette Deck with Dolby"

The (20-830 portable stereo cassette deck lets you bring
your remote or at-home recordings up to a truly profes-
sional level. We've built in the operational flexibility and
recording excellence that professional broadcasters and
journalists demand from an on-location recorder.

The three-head design of Model CD-330 means
Separate Fiecord. Playback and Erase Heads. So when
you monitor while you record. you hear exactly what's
going on the tape. giving you an instant check of actual
recording quality.

Three-head design also means each head is designed
specifically for its function-record. playback or erase-
without sacrificing any performance for the sake of
compromise.

And the record and playback heads on Model 00-330
are Super-Hard Permalloy to assure wide frequency
response. low phase distortion and up to ten times the
head life of ordinary tape heads.

The co-aao includes a Dolby Noise Reduction System
to give you noise-free recordings. But even better. weve
built in a Double Dolby System. One for recording and
another for playback. So with the C0630. you can record
in Dolby-and monitor the Dolbyized decoded signal at
the same time.

And that's only the beginning...
aAutomatic-manual-limiter record level switch provides
the option of setting record levels manually. or using the
built-in automatic record level (ARL) circuitry. The limiter
automatically protects against high level input signals.
so sudden volume increases wont cause distortion or
tape saturation. Separate left and right channel record
level controls assure precise balancing of the stereo
signal and permit fade-in and fade-out of each channel
while recording.
oPA/play mix lets the recorder function as a PA system.
or as a sing-along accompanist. Snap in a previously
recorded tape and you can mix your voice with the play-

'back through the speaker without actually recording.
IOne-touch record allows instant recording with one-
button ease. and lets you go directly from play into
record mode.

0 DC servo-controlled motor electronically regulates
motor speed to reduce wow and flutter and to improve
speed stability.

0 Dual flmheel mechanism maintains a stable tape speed
in any operating posntion.

car adaptor, rechargeable FiBD-l battery pack).

0A 4-inch full range speaker is built in for convenient
monitoring during portable applications. A 3-position
switch allows monitoring of left channel only. right only
or both channels combined. And 2 speaker 'acks are pro

vided for connection of high quality external loudspeakers.

uFlexible bias and tape egualization adiugtments ensure

optimum performance from popular tape formulations-

dentally breaks.
