They have no signs of power going in so probably there's a problem with built in power supply. In this episode i will try to repair Logitech Z313 2.1 speakers.
Logitech z623 fixed Power button with librificator - YouTub Sadly the 2 year warranty period is over. I'd say: internal soundcards are totally ok for use in a studio, but really not suitable for a 'mobile' setup, because you never know where you're going to end up.Song Lil jon donte turn up sot muchr volume and bass with this system z623 50% bass 60% volume to not damage the Power button has sensitivity and sometimes shuts down the speaker system when barely touched This is my second Logitech Z623 and its power button also has developed the same issue as the original.
Having several options is always nice, we didn't have to use them a lot, but when we did, it saved our production! The inputs of our capture cards (via the cameras) are the last fall back option. We can also use the soundcard as a mixer (not as handy, but it works). In case of troubles with the external soundcard, we can always use the mixer via usb as a soundcard (only 2 channels though) or in case of emergency we always have the internal soundcard as a backup. The mixer has several busses, so we can send out 6 channels seperatly into the soundcard. The mixer allows us to have physical control over our sources and to use pads and EQ to control the sound better. All of this comes into a small Yamaha mixer and goes via the output into a soundcard. Some XLR cables to microphones (shotguns).
DELTACO USB SOUNDCARD AUDIO ONLY ONE SIDE PROFESSIONAL
It's this gig that learned us the importance of balanced audio cables (XLR) and professional soundcards.Īfter this, we also learned the hard way the importance of physical controls for sound: if an input is clipping, you really want to have good visual representation of it and a gentle way to control it.Ģ DI boxes which sit in between the source (PA system) and our XLR cables. The boat transferred a huge buzz towards the cables, and we had no way to fix it! One time we had a gig on a metal boat with a generator. We started out with onboard sound via the realtek soundcard. The Behringer usb interfaces are excellent alternatives but embedded sdi digital audio is my preferred option from the camera. My Blackmagic video cards sound so much better than the `HD' on board audio. I've never been keen about on board audio with its unbalanced lines in a digitally noisy environment. Through a glass delay line and now we are plagued by delays that we don't want - for free. In the early days of PAL D colour TVs the cheapest way to delay the video one line was to send it Getting rid of a stage of a/d conversion is probably not going to make a dramatic difference to an existing "noticeable lag". It's ironic that in a (old fashioned) fully analogue video signal chain it's almost impossible to add any video latency beyond that which is typically measured in nano-seconds, whereas the introduction of digital (and transmission via computers/software in particular) has added cheap/easy (and sometimes essential) frame buffering at various points in the signal chain, which can quickly add up to several frames of end-to-end latency between locally connected equipment. there is a noticeable lag between the on-stage action and the data projector but that will be addressed when the cameras and capture card go fully digital and we get rid of the A-D latency.
