Pioneer T-03SR

Commentary

Reverse deck equipped with Dolby S and FLEX SYSTEM.

Equipped with Dolby S as a noise reduction system.
Noise reduction effects are obtained over a wide band range of up to 24 dB in the high-frequency range and up to 10 dB in the low-frequency range, and micro-level recording and playback and bleeding noise are also improved.

It is equipped with Frequency Level Expander (FLEX) System in order to reproduce HiFi sound without clogging of the tape.
This system determines whether the recording tape contains sound, and automatically amplifies the high-level sound up to a predetermined ideal value in a way that does not reveal the hissing, thereby achieving clearer sound quality.
This pre-determined ideal value sets the 1/f characteristic of most HiFi music, making use of the 1/f characteristic, which is considered to be a sound that is pleasant to humans.

Equipped with FLAT SYSTEM which corrects the frequency of the tape to be flat and draws out the tape performance.
In this system, the bias, equalizer, and sensitivity are corrected at three points : low (400 hz), middle (3 khz), and high (10 khz). The operation is automatically controlled by the microcomputer in the order of bias, level, and equalizer in a short time.

Equipped with a last memory function, it can store FLAT SYSTEM bias, equalizer, sensitivity data, Dolby NR, meter range, switch on/off position, electronic counter numbers, etc.

Equipped with the Dolby HX-PRO, it detects the wide-range signal flowing in the recording head and controls the bias current according to the increase or decrease of the signal, preventing the occurrence of self-bias and greatly improving the high-frequency characteristics.

Wireless remote control is included.
