    Wanted Descent i Amplifier Module.

    Unlike the Summits, I don't think this is a common part that is available from parts suppliers, so you'll have to get it from ML. The board has a ML logo on it.

    Issue with Summit Amp

    Happiness is when things are working as they should be. The heat comes mainly from the transformer. It gets too hot to touch. With 2 of these 'heaters' next to it, the back plate gets very warm after a while at the spot just above the dimmer control. Even when on standby, it looks like the...

    Issue with Summit Amp

    pambs, I hope you got your bass speakers working again. It happened to mine once when I forgot to connect the speaker cable to the board after an ICE amp replacement exercise. Duh. 🙄 Low hum (even without input connections) appears to be a normal feature of all ML bass speakers and woofers...

    Is the Descent fused internally?

    The Descent_i emerges from standby mode automatically upon receiving an audio signal. There's no need to "switch". If you are certain the problem doesn't come from your processor, I suggest you contact ML service. Scott Gribble or Brian Bailey are very helpful, though there might be a delay in...

    Issue with Summit Amp

    It exactly the same board that ML will supply to you. In fact, it was Scott himself who suggested that I could get it for a lot less on the open market.

    Is the Descent fused internally?

    Not as far as I can remember. I have had the misfortune to require a complete change of all the circuit boards sometime ago and don't remember seeing any fuse on the power supply board. Edit: Appears our posts crossed. Congrats on your solving the issue. Enjoy!

    Summit bass?

    Pamps, Is yours the Summit or Summit X? Does your amps feel just as warm, or even hot, whether in active or in standby mode? The spot to feel is just above the LED control at the back panel. I am trying to determine if the standby mode circuit on my speakers are defective even though the LED...

    Issue with Summit Amp

    Pambs, FYI, the Summit amps (ASC 200 from B&O) are easily obtained from open market suppliers like Parts Express https://www.parts-express.com/icepower-200asc-class-d-audio-amplifier-with-power-supply-module-1-x-200w--326-208 and they cost a lot, lot, lot less than from ML. I recently had to...

    Summit bass?

    Nothing is wrong with my house wiring. The trip issue was brought to ML's attention. They confirmed on paper (I still have it) that there's a surge of a total of 143.118 A during the first 0.003 sec when both speakers are turned on together. The surge drops to 42.936 A at 0.01 sec. That's...

    Summit bass?

    Don't know whether UPS is suitable for the Summits. When I first had mine, it used to trip my mains fuse whenever I power them on because of the very high transient. So, now I power them on one at a time. I really don't like to power off the speakers every time I turn off the system. I find...

    Summit bass?

    The sub was already about 8 years old in 2014. ML shipped me all the speaker units, circuit boards and wire harness. It was a back breaking job working in the confined space inside the enclosure screwing everything in place - I didn't trust my dealer's men to do a proper job. Don't really...

    Summit bass?

    Count yourself lucky, Khenegar. Look at what happened to my Descent-I. One of the 3 ICE amps caught fire. Besides disabling the other 2 amps and the PS board, it also blew up all 3 speaker units. The only item salvaged was the enclosure. Maybe I am jinxed. :wtf:

    Summit bass?

    Most subs are self powered with ICE amps these days. Mostly because they run relatively cool and so do not require heatsinks.

    Welcome to the Schematics subforum of DIY

    Hi Guys, Does anybody here have the schematics for ML Summits? I am toying with the idea of bypassing the internal ICE bass amps and using external amps to drive the bass units. Thanks.

    Summit bass?

    He didn't. Just said that it's unusual that the ICE amps should fail slowly over time instead of simply stopped working. I am concerned that the new amps won't last long as these new version "K" is specified to draw 45 watts of power compared to 39 watts for the earlier versions. And they...
