Fera / RFT (Fernseh-Radio) HiFi 50 Quadro-effekt, 1974, made in Germany

Link: radiomuseum

The amplifier 50 HiFi Quadro effect of PGH TV-Radio Berlin is the successor of the famous HiFi 50. He is the first hi-DDR-home amplifier having the connection for two additional speakers to pseudoquadrofonen playback. This process should not be a substitute for real quadraphony, but is intended as an improvement of the stereo reproduction that significantly improve the three-dimensional sound image despite the low technological effort. The electrical and mechanical properties would otherwise remain virtually unchanged compared to the HiFi 50, so the description largely done with the text. ifatwww.et.uni-magdeburg

The amplifier has on the rear side of the tape 5 inputs, phono, tuner, micro and specialty, the latter is mainly intended for the connection of electronic musical instruments that can be selected via a push-button set. The signals of the five inputs, which have a total of 3 different sensitivities are input, coupled to the base of the three-stage input amplifier via various passive RC networks. This is equipped with low noise Miniplast transistors, thermally very stable and due to strong negative feedback relatively insensitive to transistor manufacturing tolerances. An equalizer amplifier for magnetic sensing systems for the phono input is not provided in HiFi Quadro 50 effect.

The preamplifier is in two stages and also equipped with low-noise transistors. It allows dual potentiometer on the control for bass, treble, balance and volume, the latter is affected aurally. A rumble filter and the Mono button is still available, the existing the old model noise filter has been replaced by the contour button, which should provide at low volume for a more brilliant sound.

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 in Darlington circuit. It is powered by unbalanced supply voltage and thus requires Auskoppelelkos. In a speaker protection circuit, and a delay was waived. Only an overdrive protection circuitry has been provided which abtennen briefly about each one relay the speakers at excessive level peaks.

The HiFi 50 provides connections for 2 speakers and a stereo headphone, said the non-switchable socket is located on the rear panel. He also has a red lamp as network control, and red clip indicators for both channels, in addition a green stereo display is now available.

The optical design of the HiFi 50 is simple and technically in a modern, slim case made of wood. The front panel is made of black painted aluminum and is labeled with a white screen printing in German. The round keys are made of black plastic with chrome cap, the knobs are made of chromed plastic.

Another variant has a two-part front with black frame and silver aluminum front panel. The keys are square and made of black plastic, as well as the knobs.

The HiFi 50 Quadro effect was presented at the Leipzig Autumn Fair 1974, the first time the public.

Rocktron RSP Technologies Intelliverb 24-Bit Virtual Room Processor (w/psu), made in USA

This Rocktron RSP Technologies Intelliverb 24-Bit Virtual Room Processor (w/psu) is in very good working and playing condition and has been fully tested by our pro audio shop. wurlitzerboston

The unit shows normal signs of wear from use and rack mounting. The rack ear corners are slightly bent (refer to photos) and the level control switch button is missing although the control can still be pushed. Includes original power supply

Description:

The RSP Intelliverb is a 24 bit intelligent effects processor providing 6 unparalleled effect algorithms and superb sound quality not found in effect processors twice it's price. Complete programmability and full MIDI implementation are coupled with a user-friendly operating scheme to ensure that designing both unique and useful preset sounds is a simple as possible.

Providing Virtual Room reverberation, 4 voice pitch shifting, 8 voice stereo chorus, various types of delay effects, delay ducking and HUSH Systems' fully digital implementation of HUSH noise reduction, the impressive sonic quality of the Intelliverb is, in part, due to the incorporation of three individual 16 bit converters and Sigma-Delta A/D conversion, achieving a 64x oversampling rate and dynamic range of over 100db.

To achieve the maximum possible performance (zero wait states) from the Digital Signal Processor (DSP) engine, the Intelliverb uses a large number of very fast (and expensive) Static Ram (SRAM) memory IC's. All other digital effects processors we have examined, including ones costing several times the price of the Intelliverb, (except the Rocktron Intellifex), use much slower and cheaper Dynamic Rams (DRAMS). This extra-powerful hardware allows the Intelliverb's Virtual Room algorithm to achieve unequalled levels of room simulation.
