Grundig 3035 3D Klang

Grundig 3035 3D Klang is a device classified as medium class of Grundig.
Like some other devices of the 3xxx serie, this one is also particularly interesting.
The thing about this radio that surprised me is the extraordinary reproduction of the spoken parts.
The music is well reproduced but the transmissions where the presence of the speaker is dominant are really impressive.
The voice is present, well balanced and preponderant. All shades, including speaker faults or habits are understandable.
In my opinion, this device is appropriate to the “typical radio listener”, turning on the radio in the morning, turning it off in the evening and listening without temporal continuity to radio commentary, interviews and music.

The Output stage is a classic A-Class with an EL84 valve as final and the triode section of the EABC80 valve as a preamplifier.
The device is equipped with 4 loudspeakers, one of which is an electrostatic frontal tweeter.

At the back of the radio, there is a visible socket where it is possible to connect a remote command. It is possible to turn on the device, adjust the volume and insert some predefined equalizations.
All of this is certainly not standard equipment for middle class devices, but for far superior devices.

The cabinet is important for its size, which guarantees a split between frontal and posterior emissions of the loudspeaker.
The loudspeakers of these radios have been mounted in a particular configuration “quiet open Baffle” whereby a big separation surface is very important for an efficient reproduction of bass notes.
The sound is substantial but the strong point of the radio is the clarity of reproduction of solo instruments and of the voice.

历史

1930年:22岁的Max Grundig开始从事于无线电修理业务。

1939年:第二次世界大战开始。Grundig工作主要专注于国防军和电信设备修复。

1945年:战争后立即性的修复工作需求非常大。Max Grundig建立了根德Tubatest管测试仪和Novatest测试装置。

1947年:开始Heinzelmann无线电的销售。售出超过15000件,这可是一个成功的基础。

1950年:VHF被引入到德国后,造就工业新的需求。Grundig推出380 W至市场。

1952年:德国第一个电视频道诞生。经过深入研究,Grundig推出FS 080至市场。同年,创建第一台手提式磁带录音机Reporter 500 L

1956年:在大量高性能收音机生产后,Grundig推出了Concert Radio 5080,它配备了一个声音均衡器,其中含有五个控制钮和可视化显示。

1965年:新工厂设立在布拉加,葡萄牙。Satellit 205Satellit系列中电器之一。Grundig高品质受到全球的关注正由Satellit 205开始。

1970年:推出Audiorama 7000 Hi-fi,这一个扬声器含有十二动态扬声器系统。

1976年:推出TS 1000磁带录音机给半专业人士使用。

1980年:超薄音响调谐器ST 6000和整体音响动态平板天线,其中有22个扬声器系统,在新的音响范围内的两个特别受欢迎的电器。

1984年:在销售严重的下降后,飞利浦增加了其在Grundig 31.6%的股权并接管公司的管理。

1997年:飞利浦退出Grundig

2003年:公司提出破产。

2008年:土耳其的KOç控股公司从Grundig Intermedia GmbH in Nuremberg买下了Grundig Multimedia B.V.,全部股权。

AM採用旋转镍锌铁氧体天线

音调控制

音调控制系统是非常有效的,在音调控制大旋钮上,你可以找到一个小窗口,黑白颜色对比逐渐显示出对高低音比例。
A detail specific for “extreme” technical radios lovers: the high-tone control knob is linked to two thin ropes. One of them is for the position indicator of the control itself, whereas the other changes the position of the ferrite in the MF transformers modifying the inclination of the transformer’s curve.
By doing so high tones were attenuated/accentuated even before getting to the BF stage. Tone control was usually put into effect with the potentiometer on the tension amplifier stage

天线

机壳内有一个半波偶极天线FM调频接收和旋转镍锌铁氧体天线AM调幅接收。
旋转镍锌铁氧体天线可以从外部旋转,实现了在AM调幅完美的调整。
在这张图片中,看到旋转机构和空中的位置指示器。具有内部天线的接收灵敏度很好。
使用外部天线灵敏度进一步增加

AM调幅和FM调频是各自控制调谐

调谐系统是另一个特点
该单元配备了保持独立的AM调幅和FM调频带的机制。
调谐钮是单一的,但有一个选择器开关通到电缆系统(全不锈钢)和滑轮分离。
这转动是伴随着两个复杂的滑轮和分离齿轮的转移机制。

扬声器

There are four loudspeakers. In front there is a fixed big wideband loudspeaker and an electrostatic tweeter.
On the sides are placed two elliptical mid- tweeters.
In this way, it is possible to listen to a clean sound from whatever position you listen.
Of course, this radio should not be placed in a bookcase or in furniture that covers the side surfaces.

FERN-DIRIGENT

Remote control connection “fern – dirigent” allows control of the start, volume and equalization.
Below on the right, you can see the diagram “remote control”. It is not easy to find.
The price of the fern – dirigent starts from a minimum of 350 euros and very few are sold in Italy.

To the left is the volume control (with built-in loudness).
Axially on the volume is the ferrite antenna rotation command.
You see the antenna position indicator.
The AM scale for Court Waves, Medium and Long.
The FM scale.
The magic eye indicating the perfect tuning of each station.

Below to the left we find the off key, turntables key.
The key to tuning on Long, Medium, Short Waves, FM, FA (Ferrite Antennas).
Below each key is indicated the frequency band concerned.
There is finally the knob of the tuning, whose movement is very pleasant being supported by a large flywheel.
Below we find the two big knobs for controlling bass and treble.
