TRIO (KENWOOD) KF-6011 Solid State Audio Denoiser - In the original box

SOLID STATE AUDIO DENOISER MODEL KF-6011

KENWOOD's KF-6011 does not belong to the conventional noise filter which exclude necessary signals together with noises. It functions as the S/N Stretcher or Noise Reduction System used in the process of disc production, and electronically eliminate the noises included in the sources.
Thanks to its exclusive circuitry, KF-6011 remarkably increases the signal to noise ratio and fully refreshes the program sources. It's especially profitable for tape dubbing.

1. MINUTE DENOISING
The KF-8011 decreases the noises between 3kHz and 15kHz, which affects most badly on the sound performance, by 6-10 dB. The built-in Frequency Selector enables to pick up the particular frequency range in order to denoise precisely.
2. NOISE LEVEL ADJUSTOR The KF-6011 features a large Level Meters and 6-step type Level Adjustor for setting and monitoring the suitable level point of program sources. In addition, the volume of cutoff noises can be controlled by the Noise Level Adjustor.
3. SUFFICIENT INPUT JACKS As the Denoiser is to be connected to the REC/PLAY terminals of an amplifier, KF6011 has the complete input & output jacks for tape decks including DIN connector. It also has 4 pairs of input jacks and by the Input Selector on the front panel 4 sources are switchable.
4. CHECK SYSTEM FOR DENOISING CONDITION The built-in Defeat Switch permits to check the denoising condition - what frequency range is to be denoised, how much the S/N ratio has been improved, etc.
5. AUTOMATIC CIRCUIT SWITCHING
As shown on the following diagram, the Denoiser is to be inserted to the input side when making refined recording, and to the output side when enjoying refined playback. It is, however, quite needless to re
connect KF-6011. The Denoiser Position on the front panel switches the circuitry automatically.
