I noticed the following differences : - A completely different protection board under the chassis: smaller, no ref, only 4 transistors (of which two 2SC1213, one 2SC883 and one 2SA537A). No schematic...

    Shielded Twisted Pair (STP) RCA cables for unbalanced differential-circuit analog input

    I'm hoping to get a little advice, and maybe a product recommendation, for a roughly 15' 4-channel Shielded Twisted Pair (STP) RCA cable (or cables...) to use with the differential-circuit equipped multi-channel input of my Anthem Statement d2v 3D. There don't seem to be a lot of clear...

    Using only RCA Cables with 75 OHM Configuration for Single Ended Analog Inputs

    I saw this video today on YouTube, . It’s D’Amore Engineering explaining that we should only use 75 Ohm cables with single ended analog inputs, and twisted pairs on differential analog inputs (more rare). This video is short and concise, and the logic makes sense to me. Unfortunately, I’m...

    Is this possible, XLR for sansui au d33

    Hello good people. I have a question for you. I have seen a lot of sansui amps having XLR inputs on the back for straight to power Amp. I am wondering if it is possible to do the same thing to sansui au d33. I may not fully understand this, but to me it seems like it is a differential...
