Re: Pioneer DDJ-SZ XLR right is distorting
I use a 100Mhz scope for everything, but I am not only doing audio.. For audio even a 50Mhz scope is enough. A 200Mhz scope is nice, but to 95% not needed. It really depends on what you want to do and how future projects proof you wanna be.Comment

Re: Pioneer DDJ-SZ XLR right is distorting
Yeah thats what my friend said as well. Since i only use scope for audio purposes, he asked me to get the 50MHz scope, he said thats more than enough for audio repairing. So i might a portable chinese ones. As i dont use scope all the time, so i dont want to really waste a lot of money on something i rarely use. Been reviewing the portable ones, seems good so far. Does the basic jobComment

Hi guys I have a VLP1500 amplifier here - one channels works fine and the other channel distorts even at low volume settings
Protection and Clip LED are off
There is something wrong with the BIAS voltages around T16 and T18 (in particular) on the bad channel
I tested all diodes and transistors in this area in circuit with diode mode - both channels seem identical. Same in resistance mode across all the resistors here.
The output DC voltages on pin1 and pin8 of the 5532D dual op amp at the input of each amplifier module are the same, and the audio... -
Hi friends
I have reverse engineered this tester, schematic is attached and is complete except for capacitor values. These testers annoyingly have no model number but they are the ones you find on the first page of just about any website if you type in "18650 4-channel tester". There is also a 2-channel variant and a newer 8-channel variant. They are very cheap (about £15) and can measure voltage, current, internal resistance and capacity. They have a multicolour display for all these statistics. They also have terminal blocks so that if you want to use a breakout board... -
Hi Guys
I have a customer who has two Hitachi TVs in his bar, one is the model in the thread title and the other is a larger screen but has the same setup menu
He also has an LG TV, so three screens in the bar
I installed three Satlink ST-6503 DVB-T Modulators
This model https://www.aliexpress.com/item/32916553905.html
These connect to three satellite receivers via HDMI cables and then connect to a 4 way RF Amp that connects to the TVs on aerial cable. There is no incoming terrestrial antenna. I set the channel ID on the modulators to... -
Hi guys,
I need a help with my Marantz pm6005. It started to have weaker the right channel a few months ago, than it got back to normal and now it has lost sound completely on the right channel. At the final stage it was loosing the channel for a while and than it returned. After it has disappeared completely I could forced it back by unplugging the source form CD (which I normally use) to phone and back. It would then work for a few minutes and died again. Now it is possible power up and all function works normally (apart the right channel ) on all inputs, except the phone both channel...01-30-2023, 12:11 PM -
So my dilemma is that I can't seem to get my board to run in Quad Channel. I have an X10DAX with Dual E5 2690 v3's and originally it had four 16GB sticks of Samsung ECC. Figuring I needed to have a stick for each DIMM1 slot I purchased four more identical sticks of Samsung M393A2G40DB0-CPB. So, now I have eight 16GB sticks for a total of 128GB of RAM. When I install the ram so that Each DIMM1 slots is populated the system will not post even if I clear the CMOS, remove the battery, what-have-you. But according to what I'm reading in the Manual, which is admittedly not very clear, populating each...
