Unlike the trigger for ICEpower, the 'disable' switch for Abletec's module is actually a disable. 5V will disable the amplifier, so you will need to come up with a PCB that brings the trigger to ground or 0V when a 12V trigger is connected and turned on, and supplies a very low current when the triggering device is turned off.

i hope someone can help me with this
for the abletec alc1000 modules, the gain is 33.5
i would like to drop that to more comfortable levels like 28db, how can i do this?
would a H-pad work, this is a term i found online, and i am not 100% sure how this works, but 33.5 is way too much, and i rather not attach a attenuator outside of the amp.

Hi, Im in the process of building one of these. Just waiting for parts to arrive.

I was wondering if it would be possible to use the 12v trigger from the processor to switch a relay in this power amp using a basic 3.5mm mono jack wired up to suitable relay and in turn to the mains IEC connector.

Im not clued up on electronics in the slightest though.

Would the relay liely introduce unwanted noise in to the circuit and affect its performance?

Hei Svein,

Where did you buy these cases? They look good and have solid cooling ribs.
I've looked for cases at Modushop and the only one that fits ALC1000 well is GALAXY Maggiorato, but it probably can't take much heat.

hi i have mine built in the Galaxy Maggiorato, and after 5-6 hrs, they are very cool to touch.

Those cases are from TAKACHI ELECTRONICS ENCLOSURE CO., LTD.
the cases that he used from takachi were the HY88-23-23BB
http://www.takachi-enclosure.com/dat...52_155-156.pdf
and current price, i inquired a week or so ago is $100.39 USD per case
and shipping pretty much starts at $100 USD

i bought a few cases from takachi, not the HY series, bought the HIT and MS series, and found that overall quality of takachi is lower then modu

Thanks for the answer!
So something like the Galaxy Maggiorato with 230 mm (width) x 280 mm (depth) should work fine with ALC1000 then.

The ones from takachi do look nicer, but at a higher price as well.

mine were the 230x230mm, you can see the picture i posted above, that is the alc1000 inside the galaxy maggiorato 230x230

i applied thermal paste on all outside surfaces of the alc1000, and it touches my case on all sides.

Hey , thanks for posting, I asked Svein about his cases a few days ago but hadnt got round to emailing them for a quote. It does sound expensive.

Im intrigued by the Modu cases though, esp at the lower price and the customisation available.

Dont suppose any of you have sussed out the standby function? or 12v trigger?

I just got some ALC0240 modules, I would like to run them in bridged mode with unbalanced sources. I am thinking of using a jensen jt-11p-1 transformer for isolation and to convert RCA to balanced.

But, then what do I need to connect the output of the transformer to on the amp board? I understand that one channel is internally wired inverted for the rail pumping issue. Thoughts?

Thanks

Finally, there is the curious absence in Abletec’s specifications for the amp of its input impedance.

In order to avoid pumping of the power supply rails, Abletec has the left channel of the amp connected in non-inverting mode and the right channel in inverting mode.
