The HiFi amplifier V150 is technically the successor to the HiFi 50 and a part of the component system Fera 150 from the PGH TV-Radio Berlin. It is based technically, as well as the rest of the resort, on a proven and reliable switching principle with good technical parameters, but for which also caused no real innovations in the GDR market. ifatwww.et.uni-magdeburg
The amplifier has 5 inputs TA, TB 1, TB 2, Tuner and Reserve (eg for a television set), which can be dialed in an amplifier from the GDR, via a rotary switch instead of push buttons set the first time on the rear panel. The signals of 5 high level inputs are from the rotary switch to a common input amplifier as an impedance converter, which is equipped with low-noise transistors supplied.
The preamplifier is built in classical discrete circuitry. It is equipped with two-stage and low-noise transistors, the tone controls for bass and treble, as well as the volume and balance control is provided by dual potentiometer. The loudness control can be disabled with the "Linear" button continue you can switch to "Mono".
The power amplifier, a four-stage electrically coupled network is set up discretely, fully equipped with silicon transistors and operates as a quasi-complementary output stage. It is powered by unbalanced supply voltage and thus requires Auskoppelelkos. In a speaker protection circuit, and a delay was waived.
The V 150 provides connections for 4 loudspeakers, two of them to pseudoquadrofonen playback. The two pairs are selected via a rotary switch, for pure stereo or Pseudoquadrobetieb. The headphone jack located on the front panel is therefore not, as usual, be controlled because the speaker can be either manually shut down with the rotary switch.
The V 150 has a red LED as power control, on the overload indicators used at HiFi 50 but was omitted.
The visual design of the Fera devices is plain and technically, but through the relatively large housing made of wood a bit old-fashioned for its time.
The plant was silver and black property offers in the colors of both the housing and the aluminum front panels are painted in the respective color. Deviating there are also silver anodized front panel, the label carried by a black or white screen-printing in German. In the first devices only "Fera" was a label on the unit, later additionally "RFT".
The knobs and buttons are made with the silver vessels made of metal, in the black plants made of plastic, the back wall is made of cardboard.
The Fera V 150 was presented at the Leipzig Autumn Fair 1981, the first time the public.
Сверхнизкий бас! Лютый кач! СЧ-ВЧ можно нерационально регулировать до максимума и получать тот самый песок в тугих АС. Рекомендую для тех кто ищет НИЗКИЙ БАС и яркое звучание. Отличная отработка по динамике.
