GRUNDIG Monolith 190 (1980) - Active Sound Wall

 

active loudspeaker

The first Laboratory Refence prototype of a 190 cm tall and 65 cm wide active soundwall was presented by Grundig at the 1979 Funkausstellung in Berlin. Due to large public interest a commercial model was released in 1980, this was the Grundig Monolith 190 Active Sound Wall, work of Dr. Arnold Glaab. The loudspeaker uses a system of three sets of vertically arranged speakers. It features 8 twin-series-parallel bass speakers, 7 series-parallel dome midrange speakers and 7 series-parallel dome tweeters for a 22 speaker wall of sound driven by 4 dedicated built-in power amplifiers. Each amplifier works in a frequency range determined by the active crossover network. Total power of a loudspeaker is 160 W nominal - 250 W music power (short term) while the frequency response is 20-25.000 Hz. The loudspeakers have to be connected to a pre-amplifier such as the Grundig XV 7500 which is capable of driving two sets of Grundig active loudspeakers. Each loudspeaker measures 68*192*46 cm, weighs 83 kg and the left and right loudspeaker are built in a mirror image speaker arrangement. Original sale price was 2800 DM per speaker.

Fine Arts Esoteric Line CD tube pre-amplifier (1987) - ... by Grundig

pre-amplifier

Grundig's first product manager, Dr. Burkhardt Schwäbe was the driving force behind the Fine Arts Series. It was meant to demonstrate Grundig's expertise in the premium Hi-Fi segment. The Fine Arts Esoteric Line CD tube pre-amplifier was created in 1987. It's main design features are a complex power supply with toroidal transformer, electronically controlled DC voltage heating, double volume control (from ALPS) and four E83CC tubes from Siemens. Originally it was planned to use Telefunken ECC83s but those were unavailable at that moment. There are inputs for CD, Tuner, DAT/Tape and Aux (no Phono input) and can be used with a wide range of transistor or tube amplifier. The gold version has 24 carat gold-plated surfaces and there were built a total of 127 units. Dimensions: 310 x 124 (+11) x 220 mm.

Towards the end of the 1990s Dr. Burkhardt Schwäbe moved to Sennheiser and in 2004 he launched his own brand, Eternal Arts and more recently Eternal Masters (pre-recorded tapes and audiophile LP).

GRUNDIG XPC 6500 TP (1979) - HiFi Studio, Electronic Total

music center

Music centers were very popular in Europe with most european manfacturers offering a wide range of all-in-one music centers throughout the 70's. One of the most sophisticated, if not the most sophisticated, was the GRUNDIG XPC 6500 TP introduced in 1979. While most music centers were all in one units, this Grundig had a slightly different approach. Instead of a built-in amplifier section this model only had a pre-amplifier section that could be partnered with a wide variety of Active loudspeakers from Grundig. The pre-amplifier section is a Class-A construction with 1 Volt output (for the active loudspeakers) and all electronic control with LED status display for tone control, balance, volume control and source selector. The radio section can receive FM Stereo, AM and LW radio programs, it has automatic and manual electronic tuning, again with LED and LCD status displays and 10 presets. 

The cassette section is Grundig's own design (the CB 230 A TP module) with one motor, Long-Life recording/playback head and mechanical control. The cassette recorder can handle Normal, Chrome and Ferrochrome tapes (30 Hz to 16 kHz all tapes) and it features Dolby noise reduction circuit. The turntable section is a DUAL 491 ARC (see here) Direct Drive model with Shure DM 95 G cartridge. All the electronically controlled functions can be remote operated with the TP 6500 ultrsound remote control. With the same remote the turntable start/stop and arm lift can be controlled while for the cassette section only the pause function was remote controlled. Dimensions are 690 x 200 x 430 mm

GRUNDIG mini 100 (1980) - Designed and Built in Germany

mini hifi system

Grundig was the largest and one of the most respected audio electronics company from Germany. Their products were kept in high regard throughout Europe but not only. This means that in 1980 they were still able to release a competitive product such as the Grundig mini 100 HiFi on a market segment dominated by japanese audio products. It was proudly advertised as Designed and Built in Germany. In this Grundig mini-series we will find receivers, tuner, amplifier and various cassette decks. In this article we focus on the top of the line components of this series. These are:

GRUNDIG MT 100 - analog FM Stereo tuner with 7 presets
GRUNDIG MXV 100 - stereo pre-amplifier that can be used either with the MA 100 power amplifier or directly with one of the XM series active loudspeakers.
GRUNDIG MA 100 - 50 W/ch stereo power amplifier with auto power on-off when used in combination with the MXV 100 pre-amplifier. To counter balance the aesthetic appereance of this slightly larger box a funny / funky little LED power meter was installed.
GRUNDIG MCF 600 - stereo cassette deck featuring a two motor Quartz locked and logic controlled mechanism. The deck can be used with Normal, Fe-Cr, Chrome and Metal tapes as well with optimal results with the help of to the front panel BIAS control. The deck features High Com noise reduction circuit that is said to be 13-times more efficient then Dolby but there was also a Dolby playback-only compatible circuit installed as well.
GRUNDIG XM series - HiFi Active loudspeaker range to be used directly with the pre-amplifier for a more compact system

All components were available with silver or metallic-brown finish.

Fine Arts by GRUNDIG - The M100 System from 1996

mini HiFi

Fine Arts by GRUNDIG were always special kind of audio components. The M 100 mini Hi-Fi system introduced in 1996 is no exception. These are all separate, idependently operable mini Hi-Fi components that consisted of three different amplifiers, two CD players, one tuner, one cassette deck and a bookshelf speaker system. List of components: 
M100-A 80W/ch Stereo amplifier with full system remote
M100-R 80W/ch Stereo RDS Receiver with full system remote
M100-ADPL 3x30 W + 2x15W Surround amplifier with full system remote
M100-CDC 3 Disc-CD-Changer
M100-CD single tray Bitstream CD player
M100-T HiFi RDS tuner with 59 presets
M100-CF HiFi Autoreverse cassette deck with Dolby B,C and HX Pro
MBX-100 bookshelf loudspeakers

All components measure 270 x 95 x 310 mm which makes it easier to stack them in any order or side by side. Add to this, convenience features like D.O.T. (direct operation technique) and you have a winner system. D.O.T. means that you can easily switch between components simply pressing the desired source key on any component or remote. So if you are listening to radio and want to switch to cassette you can achieve this by pressing play on the cassette recorder or remote. The amplifier will switch from tuner to cassette and play will began.

GRUNDIG CF 5500 (1980) - High Fidelity DIN45500

cassette deck

This was the first 3 head cassette deck from Germany's largest consumer electronic manufacturer, GRUNDIG, and the second cassette deck "Made in Germany" with 3-head design, after the Thorens PC 650. It's a complex machine built around a 2 motor mechanism with one Quartz controlled capstan and 3 Ferrite heads. For best results with any tape the GRUNDIG CF 5500 is equipped with two test tones (10kHZ, 40Hz) with separate adjustments for left and right channel. Dolby circuits are also double (recording and playback). The CF 5500 can handle Normal, FeCr and CrO2 tapes. There is separate output level control and a dedicated headphone amplifier with left and right channel level adjustments. The cassette compartiment is open type with full logic controlled mechanism, digital tape counter and LED recording level meters. The new Metal tape formulation was still relatively new on the market so there was a parallel model, called CF 5500-2, that could handle Fe-Cr, CrO2 and Metal tapes. They were both avalable with silver or brown front panel. The only distinctive visual difference between the CF 5500 and CF 5500-2 was the square LED row on the CF 5500-2 opposed to the round LED's used by the CF 5500.
