I have recently built a 6-channel amp for use with DEQX active speakers, Legend's Tikandi Be mk3. They use 3e Audio's amp modules, one stereo 260-2-29A module (shown on the LHS of the attached photo) and four mono 480-1-29A modules (RHS of photo). Between them is a 1200W SMPS with 80,000+ additional reservoir caps.
However when I turn on the amp I get a very large "bang" through the speakers, almost enough to destroy their Be tweeters. I thought it might be the power supply but it measures 47.0 V with no ripple seem through a CRO.
I also get a very large "bang" when I change music tracks with my JRiver MC program. This does not occur when I use another amp with Hypex NCx500 modules.
I measured the DC output of each module and it varied between 10 and 40 mV that does not seem enough to produce the heard effects?
The TI datasheet for the TPA3255 unit on which these modules are built says they have "Click and Pop Free Startup and Stop'.
I queried all this with 3e Audio through the AliExpress website but received no reply, only a refund for the recent stereo module which was good but still leaves with an overall amp that I cannot use - which is a shame because from limited playing of music I quite liked their sound.
I wonder if any one else has had similar problems and/or can suggest a solution?
Thanks in advance!
