The new Pioneer CT-F7171 is proof positive of a new level of sophistication in stereo cassette deck design and performance. First, it is a front-access deck, with the tape compartment located on the front panel. This unusual design - blends perfectly with other Pioneer components and enables uniform in-rack mounting without wasting space or sacrificing convenience. The ingenious, jam-proof tape compartment positions a loaded cassette at a 30⁰ -degree angle to facilitate access; a switched compartment illuminator allows instant confirmation of tape condition and travel direction. lts front-access design also means that all switches, meters and controls are sensibly situated in logical, user-oriented relation to the tape compartment on the front panel.
And the versatility of the Pioneer CT-F7171 is equally advanced. There is a built-in Dolby noise reduction system, Bias/EQ switches for normal or special-type tapes, a switched Recording Limiter, LED recording and Peak Level indicators, Memory Rewind, a Skip Button for high-speed tape search, rotary level controls, and much more. As for performance, the Pioneer CT-F7771 exhibits minimum wow/flutter (less than 0.10% WRMS), thanks to its electronically-controlled DC motor and precision capstan(roundness error 0.1 fi, while its ferrite-solid head adds to your assurance of high signal-to-noiseratio, wide frequency range and minimum distortion. Advanced electronics and daring design-the frontaccess CT-F7171 stereo cassette deck with Dolby is altogether a new direction in hi-fi tape equipment, from Pioneer.
All necessary deck operations including tape loading and unloading, are performed on the front panel. This daring design-a new direction in cassette deck thinking-enables you to mount the CT-F7171 in a component rack or on shelves along with your receiver, tuner, amplifier or other components.
There's no need to waste space by providing vertical (top) access to the tape compartment or controls. The ingenious, jam-proof tape compartment itself is slanted at an angle of 30* to facilitate confirmation of tape condition, aided by a switched compartment iIluminator.
RECORDING PEAK LEVEL INDICATOR
Pioneer has developed a unique, simple-to-use Peak Level Indicator which detects the peak level of an incoming signal within a few milliseconds. The LED (Light-Emitting Diode) indicator will never flicker or burn out. lt reacts more quickly and with more sensitivity than any level or VU meter to the exact level of transient peak signal reaching the recording head. lt lights t o warn you when the peak level of input is +4dB from reference level, particularly handy when making Dolbyized re-cordings with low-distortion and wide dynamic range.
BUILT-IN DOLBY NOISE REDUCTION
Noise-free recording and playback performance are assured by the Type B Dolby circuitry in the CT-F7171 By boosting certain portions of the highfrequency spectrum during recording, and deemphasizing them during playback, "tape hiss" is almost completely eliminated while those highfrequency sounds you should hear are allowed to come through clean and clear. A separate Dolby indicator and a simple push-button Dolby switch provide all the control you need.
ELECTRONICALLY-CONTROLLED DC MOTOR
Stability of tape travel and reliability of transport mechanisms are the most decisive factors in high fidelity cassette deck performance. Pioneer therefore has applied the finest tape transport techniques available in the CT-F7171, a double-sure combination of a highprecision capstan shaft (roundness error 0.1µ) and a dependable DC drive motor electronically controlled with a kind of servo-mechanism using solidstate devices to maintain precise drive voltage and stable rotation unaffected by power supply fluctuations. As a result, the wow/flutter characteristics of the CT-F7171 have been reduced to a ratio of less than 0.10% (WRMS)
SEPARATE BIAS AND EQ TAPE SELECTION
The CT-F7171 performs perfectly with any cassette tape you wish to usestandard, low-noise/high-output or the types which are coated with special chrome and/or ferrite compounds. There are two front-panel switches, each with two positions (normal/chrome); the BIAS switch provides optimum bias current for low-distortion, while the EQ switch controls the "70 µs" playback equalizer in the CT-F7171 (for use with chrome dioxide tapes) to provide an improvement in the signal-to-noise ratio by approximately 4.5dB (over 5 KHz) when measured against the normal "120 µs" type.
RECORDING LEVEL LIMITER CIRCUIT
Anothers imple-to-use front-panel switch handles the built-in recording level limiter circuit in the CT-F7171. Distortion caused by over-level signals during recording is avoided by first setting the input level to optimum (using the large level meters and the Peak Level Indicator), then switching on the automatic limiter. This is the same kind of circuit used in studio-type equipment, not the ALC (automatic level control) design found in portable type recorders, and is therefore suitable for high fidelity use.
HIGH-PERFORMANCE FRRITE-SOLID HEAD
Extended recording and playback life, greatly improved fidelity and other advantages are assured by the ferrite-solid REC/PLAY head used in the CT-F7171. The surface of this extra-hard, precision-gap unit is mirror-finished so that a smooth, constant head-to-tape contact is maintained, even with stiff chromium dioxide tapes. The head material and design repel dust and have very small magnetic loss in the critical high-frequency region.
MEMORY REWIND AND SKIP BUTTON
The CT-F7171 is equipped with two additional convenience features. One is the Memory Rewind function: with the front-panel Memory switch "ON", set the three-digit tape counter to "000" at the point on the tape from which you want to record (or play). When the tape has been recorded (or played) as far as you want it to go, flick the rewind switch and the tape will return to the "999" position - in other words, to the place where you started. The handy Skip Button also is easy to use: with the deck in the playback mode, a touch of the Skip Button will allow you to hear (monitor) the recorded sound at twice-normal speed, helping you to quickly locate any portion of the tape you desire.
WIDE-DYNAMIC-RANGE RECORDING AMPLIFIER
To assure that your recordings are able to reproduce the widest possible range of audio signals, Pioneer has included a recording amplifier of wide dynamic range. Maximum allowable MIC input is 9V with sensitivity of 0.2mV. Maximum allowable LINE input is also 9V against a sensitivity of 60mV.
