TC-720 - the
3-head deck for the creative recordist
If you like
to get involved with your tape recording, this is the deck for you. The bias
rotary control and built-in pink noise generator allow you to fine-adjust the
deck's high frequency response to best suit the particular tape you are using.
The Rec Level ADJ controls and Rec Cal switch allow you to further adjust the
recording sensitivity for proper Dolby NR tracking, resulting in very high
Signal-to-Noise ratio and exceptionally clean sound. The TC-720 also has a
unique built-in "real time" echo facility. You can use this to add
new dimensions of studio realism to tapes recorded for playback in both your
car and your home. All these front panel features (and more) are backed by
reliable, advanced electronics. The Closed-Loop Dual Capstan Drive keeps the
tape at an ideal tension for smooth head contact. An advanced Frequency
generator servomotor transports the tape at a constant, accurate speed with
very high torque. High-performance, low-noise amplifying circuits are used for
the mic and line inputs. All this superior performance is wrapped in a
beautiful simulated ebony cabinet.
