Hello everyone! - The future of Beoworld.
in BeoWorld Feature / Problem · Nov 10, 2026 16:02Great progress. On page 1 of the 6500 thread, the pictures can be enlarged per expectations when I click on them. When I move to the next page, the image enlargement doesn't work, but I can still enlarge the picture by r…
Hello everyone! - The future of Beoworld.
in BeoWorld Feature / Problem · Nov 10, 2026 08:01Things are improving greatly! I'm researching this newly discovered thread to help me with my own upgrade path for a 5500 retrofit: https://forum.beoworld.org/forum/imported-unmapped/beomaster-6500-slight-overhaul Some o…
Hello everyone! - The future of Beoworld.
in BeoWorld Feature / Problem · Nov 8, 2026 06:42I'm very happy to see some of the early posts show up in the searches! Using Firefox - when browsing a multi-page thread, selecting the "next" page at the bottom of the page fetches the next page, but does not bring page…
Beomaster 5500 upgrade to BM 6500 ports
in General Discussion & Questions · Nov 6, 2026 03:58@Madskp In earlier times, I had mistakenly thought that Powerlink audio signal was line voltage. It isn't - it's pulled from the output of IC5, right after the inline capacitor. I've traced everything back to where it is…
Beomaster 5500 upgrade to BM 6500 ports
in General Discussion & Questions · Nov 5, 2026 10:27Well, things are never quite as easy as I'd like them to be. After taking a closer look at the L&R sigmals, it was clear that I couldn't just tap into the L&R preamp signal without doing a little massaging. I threw the 5…
Beomaster 5500 upgrade to BM 6500 ports
in General Discussion & Questions · Oct 19, 2026 00:14I was in a bit of a rush yesterday, so I took a few moments to re-examine the differences between the PCB9 from the 5500 and the 6500. It turns out there are a few changes, which compensate for the now-missing IR circuit…
Beomaster 5500 upgrade to BM 6500 ports
in General Discussion & Questions · Oct 18, 2026 05:48Before reinstalling the display board, I always wipe down the inside of the red plastic cover, sometimes with a swab, and sometimes with a soft cloth. I've used IPA on this surface before with mixed results - sometimes I…
Beomaster 5500 upgrade to BM 6500 ports
in General Discussion & Questions · Oct 18, 2026 05:31The BM6500 PCB4/9 that I have appear almost identical to the BM5500 boards I've been working on, with some noted exceptions - the afformentioned missing external IR logic, and a bigger battery, as well as a larger ROM/me…
Beomaster 5500 upgrade to BM 6500 ports
in General Discussion & Questions · Oct 18, 2026 05:07I've spent the last few days doing some cleanup work on several BM5500s that have been waiting for a little TLC, focusing only on refreshing PCB4 (Controller/CPU) and PCB9 (Display). I was reminded of a thread posted mon…
Beomaster 5500 upgrade to BM 6500 ports
in General Discussion & Questions · Oct 5, 2026 05:56Just for kicks, I spent an hour today tracing some of the signals for Pin 1 (PL On/Off) and Pin 4 (Speaker Relay). Pin 1 piggybacks off a pre-existing +12v power-on and a 390 ohm resistor. Pin 4 connects to the SP On/Off…
What are you working on now?
in General Discussion & Questions · Sept 24, 2026 00:12Pulled these white pieces off of a nonfunctional Beosystem 5500 in prep for packing them in my suitcase for the trip home to USA. On the whole, they are not in the prettiest condition, but I’m confident I can make them l…
Beosystem 5000 working with Ben CD 5500
in BeoSystem · Aug 25, 2026 17:37The internal protocols for both the BM5000 and CD5500 are based on Datalink '80, so it should work fine. That being said, the CD control on the MCP5000 remote is a wee-bit unrefined for accomplishing things like individu…
BL3500 and the MCL/PL connector
in BeoLab · Aug 25, 2026 07:590011000111100111111100000000100 This is a curious command. If I'm decoding it correctly, this reads as follows: 00:1100:01111:0011:1111:1000:0000:0100, or "Send to 'All' an 'AND' command with N-Count of 4" + data. 'N-Cou…
Beomaster 7000 audible ticks when display changes value
in BeoMaster · Aug 20, 2026 06:41Pretty much every command you execute causes a status update to be sent over datalink, but not all signals are displayed on the Beolabs. Bass and Treble changes will also send status updates, which are primarily intended…
Beomaster 7000 audible ticks when display changes value
in BeoMaster · Aug 19, 2026 15:41Possibly sounds like you are hearing the datalink signals that are sent via the powerlink cables to alter the display on a datalink-enabled speaker. How about when you change the source input - does that also create a "b…
Adding wifi control to my Beogram RX2... sanity check my approach?
in BeoGram · Aug 10, 2026 14:07Really nice job! Looks like a very clean and simple install. I'm looking forward to seeing more of your projects.
Beomaster 5000 and later remote commands - early datalink?
in General Discussion & Questions · Jul 30, 2026 22:21Echoing madskp, the MCL82 Protocol used by the Beomaster 5000 does not remotely resemble the later Datalink 86 command structures sent by the Beolink 1000 or Beo4. There is no shared command protocol between the two syst…
Adding wifi control to my Beogram RX2... sanity check my approach?
in BeoGram · Jul 27, 2026 22:17Your approach seems quite sane given the Beogram you have. AFAIK, the RX2 microprocessor was not encoded with Datalink '86, so the "keypress simulation" you've employed is an effective alternative, provided you've taken …
Upgrading a Beogram TX-2 to Beogram 7000 specification
in General Discussion & Questions · Jun 21, 2026 22:42I have a black Beosystem 7000 which lacked a turntable, and instead of spending $1000+ to find a matching Beogram 7000, I set about retrofitting a old BG 3000 to match the look, using available parts I could buy online. …
Upgrading a Beogram TX-2 to Beogram 7000 specification
in General Discussion & Questions · Jun 20, 2026 03:57Here's a solution that no one really was asking a question about. The tiny tab that holds the thread ends which move the tone arm sled tends to snap when things bind up. This morning I took a stab at a remedy. For starte…
