Linn Majik 126 bass reinforcement speakers

Most of this thread was also posted in another thread, and was way off topic, so I thought this should also land here where future searchers for info on the Majik 126 can find it.

It arrived, sounded great for a day, and stopped working today, I'm sad.

The amp actually says "Sizmik Module".

What really pisses me off is that in attempting to check the board, in the very robust aluminum case btw, all four torx screws stripped when I popped the amp case out of the sub. I use the passive voice as, contrary to popular belief, I'm not an idiot. I know how to unscrew screws. That all four screws stripped says defect. 

Sub amps are a very special situation. High power, high heat, trapped in cramped unventilated spaces. In this case trapped inside a small MDF cavity that probably acts as insulation rather than shedding heat. 

I always do a metric ton of research before I buy. I came across significant amounts of comments, for many brands of subs, that have died, so I knew I was taking risk. When it played so beautifully yesterday I was relieved. That's why I'm so gutted today.

@Akamatsu (in the other hijacked thread) makes a good point, I guess I should reach out to the seller. My quandary is also driven by his experience with his Sizmik. Finding a local repair service is best/cheapest. The logic board still allows me access to the menus, but nothing other than the default value can be selected. That is the impossible part to be fixed by a local solder jockey. The issue is it won't come out of standby. Only the single little light indicating power is illuminated. I've reached out to Linn first though, asking if these units are still being serviced, and explaining the situation. If an essentially new amp module, versus a repair job is on the cards, given sub amp longevity, what to do?

Very sorry to hear that your new Sizmik is not working.

‘If the issue is that the sub will not come out of standby, perhaps it is not getting a signal from your RCA phono cable, or your Exakt Subbox is not sending the signal to the sub.

Try swapping out the RCA cable with a second cable?

‘Perhaps also check Konfig in the Exakt Tab, to see if it sees the Exakt Subbox, and it is set to “Mono”

You could try a reboot of the Exakt Subbox, or press the Fallback button, and try the same on the Sizmik, as it should also have a fallback button

If all else fails, try unplugging and then replugging in the Sizmik and Exakt Subbox in to see if it resets

The last thought that comes to mind is that this sub was shipped from another country and may have been through a customs inspection, thus the stripped screws? Customs is notorious for taking apart speakers looking for contraband.

First of all, don't panic. Your M126 will be repaired, and it will make music again someday.

The first thing I did was to video the problem and send the video to the seller. Mine was DOA in that it made some horrible sounds while idle. The seller was very apologetic, and very willing to make things right.

For sure, I wasn't going to send it back as it came all the way from Miami, opposite corner of the CONUS from me.

I took it to a repair shop recommended by the Linn dealer. What helped the repair process the most was getting the schematic diagram from Linn via the dealer. From that point, repair was swift.

By the way, the replacement board was priced at over $1000.

The seller offered to pay the entire repair bill. I didn't expect him to give me a broken Sizmik for free, so I offered him $150, which he was happy to accept.

Things worked out so well that much later on, I bought his Akurate Kontrol.

Yes to all of these Paul. Before I even tried to listen to anything I followed the instructions from the Linndocs on how to factory reset the unit, which I did. The instructions for using the Exaktbox sub indicate everything should be set to default. On Friday I was able to use the buttons to navigate all the menu settings. However Saturday I could use the buttons to navigate to each menu item, but could not select any settings within the sub menu.

I connected successfully on Friday using both the Exakt sub box, and my OPPO 105D to the sub. I connected them to the lowest pair of three RCA. I was able to, not concurrently, get LFE signal produced by the sub from the OPPO, and music signals when connected in this manner. So on Friday both worked, and both were able to get the unit to come out of standby (the single dot of green light on the LED panel). On Saturday, no matter which music source I tried to use, including multiple factory resets, multiple unplug and plug-ins, and different cable setups, from both output sources. Nothing could force it out of standby, and I couldn't select individual settings from each feature setting, only the default was automatically selected.

As for the customs doing something, the seller wrapped three heavy steel bands around the package, holding a nice piece of plywood in place protecting the bottom, where the woofer is located when double box packaged in the original Linn packaging. These were still in place when I received the unit, and it took superhuman effort to cut them off. So I am absolutely certain that customs did not molest it.

@akamatsu, do you still have that schematic?

I reached out to the Linn helpline spelling out everything (EVERYTHING) in this thread, and will link them to it on their reply. I'll report back with what they think the menu settings output is indicating, and why it isn't coming out of standby.

I was never in possession of the schematic. The repair person got it directly from the dealer, who got it from Linn upon request.

Could you please PM me the email of the repair shop, and the approximate date they may have gotten it?

The 126 is a lovely addition once my teething issues were sorted out. I've discovered that the sub needs a bit more of a jolt to awaken than the Exakt Sub Box puts out at 50 on the volume pot. I've found the Linn system can always wake up the 126 by quickly turning the volume up to approaching 60. 

I had also not gotten the proper measurements in SPACE. Somehow I put my head embedded half way into the concrete wall two meters from the listening position, and the sub was 90° out of orientation to what SPACE was calculated for. I discovered this as I was wanting to try a different roll off, from 68Hz down to 55Hz. Once SPACE was put in order, including this new lower roll off, the extra 3db gain I had added to the sub settings was immediately taken down to zero gain, as the bass was overwhelming! SPACE is incredibly powerful, and can be used for good and evil!

What are best practices for roll off? High or low from the loudspeaker's roll off?

The system is now completely transformed. The musical flow, the leading edges of notes, and positions of players, everything was totally lifelike. On Miles Davis, So What, Paul's bass strings, and the body of the instrument, are both tangible as separate entities in a way I've never heard before. 

On Thursday, I was working on my bike, and I noticed the Torx wrench I bought to aktivate/deaktivate my 109's and realised I should pop the trim ring off the 126 and see if it worked on the 126's fasteners. It's doubtful it had ever been tightened as each fastener took well over a quarter of a turn for each fastener. Well, sha-zam! More power. More cohesion! And the clarity came up yet another notch. And for the first time I was feeling bass through the concrete floor in my feet, and my chest! 

So everybody, tighten your drivers!

I wish I had the chance to try a sub without an Exaktbox sub versus with it. But it is fantastic now. The sub brings so much more than just bass. 

On another thread Elad has said a sub needs toe in, so I know I can look forward to even more upgrades from minor tweaks! I've heard really good reports on SVS SoundPath subwoofer isolation feet. They might keep the floors from shaking, but apparently they might add focus and clarity.

Great to hear that you have dialed in your new subwoofer with the Exakt Subbox, mated to your Akurate 212’s, and are enjoying your music immensely

There is still a clinical edge. As I just said to Zee, the problem is all the detail and musical insight lives in that edge too, so I've still gotta put the Ninkas back in and see what they do with the AEDSM and sub. They won't be 3K, but they will be different.

Paul, what volume level do you typically listen at? I'm generally in the sixties or high fifties. Often, I will get to mid seventies for brief stints.

Typically, I play music at around 60-63, but for the quieter recordings, may go up to around 70.

I don’t get any clinical edge with my Exakt system
