Modernising My Stereo System - Stephan's Digital Garden

# Modernising My Stereo System Planted: 14 June 2026 Last tended: 15 June 2026 ![[stereo-system-01.webp]] I seem to be oddly lucky when it comes to chance encounters on marketplaces such as eBay, or its Austrian counterpart, "Willhaben". As I furnished my living room earlier this year, I stumbled across a Panasonic all-in-one stereo system from the late 70s, with an almost suspiciously low price (at least in relation to what I imagined such a system would cost). It seemed like the perfect find, as it answered the question of what I'd put on the center shelf of my living room, while also checking a long-held item off my nice-to-have wish list: a record player. ![[stereo-system-02.webp]] After a brief demonstration from the seller, whose passion for music was well reflected in his flat covered with stereo systems, vinyl records and instruments, the purchase felt like a no-brainer. Thus, I became the proud owner of a [Panasonic SG-2075 L](https://www.hifi-wiki.de/index.php/Panasonic_SG-2070_L) stereo system, featuring a belt-drive automatic turntable, a cassette recorder/player, and a radio tuner with SW/LW/MW/UKW (FM) bands. > [!info] Panasonic SG-2075 L > > All search results refer to the SG-2070 L, likely making the ==SG-2075 L== a regional variant.

Coincidentally, my father was also looking into solutions for adding Bluetooth functionality to his stereo system. Eventually, he found a device that'd turn out to work for both our needs respectively: the **Omnitronic BDT 5.2 Bluetooth Transceiver**. This device would essentially allow me to stream music to my stereo system, utilising its speakers. The installation is simple: the stereo system has an AUX IN jack on its rear panel, meant for e.g. using an audio amplifier. Using a **5-pin DIN to AUX cable**, this port can be used to establish a connection with the Omnitronic. ![[stereo-system-03.webp]] By selecting the correct source and switching it to "receiving", I can now stream music from my phone to the stereo system, while staying in full control of the speakers (bass, treble, balance, etc.). ![[stereo-system-04.webp]] ## Creating a Music Player Hub (WIP) An idea that sparked recently was creating a sort of music player hub: instead of relying on my phone to stream music to my stereo system, I'd use a dedicated device, perhaps a tablet, which is stationary and placed right next to the setup. After doing some more research, I learned of the possibility of creating such a system[^1] using a ***Raspberry Pi*** and ***moOde audio player***, an open-source audio playback solution. As of writing this entry, I'm still in the midst of doing my research on how to build such a system, but once I get to realise it, I'm going to write a dedicated entry about it.
