happy 2021 :-)

And I'm still here too!

Pop the tops off the mains plugs and check the screws are all tight. You'd be surprised at the number of appliances that come in for service where the screws inside the 13A plugs are actually rattling around inside the plug. It's very common on multi-way extension leads because they often crimp little brass ferrules on the ends of the flex and this can prevent the screws biting the copper properly. Make sure you're using the correct laptop charger and if it's meant to have an earth wire, it isn't cut off.

I've come across this before, laptop applications crashing from seemingly unassociated electrical events. You might just want to check all your mains connections especially inside 13A plugs on extensions and leads in case there's a loose terminal or slack fuse. Apart from that, there isn't alot you can do other than play with the order they're switched on.

the fault with the mixer will probably be the send/return jack sockets underneath the main outs, change the sockets for new ones. No I know you never use them. While the cover is off, resolder the ribbon headers on the module boards.

It's standard dichroic filter glass, though you may be limited in choice of colours you can buy at sensible prices. It's attached by low modulus high temperature clear silicone sealant or similar (dont use bathroom caulk). DFB Warehouse sell it singly and ebay etc

most twin-colour lasers use 2 seperate laser units, either supplied off 1 power supply or sometimes with a power supply each. So, you need to check which is to blame, the easiest way if you have a few with different symptoms is to swap the modules by a process of elimination. Unfortunately QTX don't like supplying spare parts so you may be forced to repair at component level or just make some complete units up out of what you've got.

You should really only master-slave lights that are specifically designed to be connected that way, unless serendipity means they have the same channel attributes and effects. The best way would be to invest in a controller, set the lasers to slave/dmx and then design your programs to sync them if you wish with individual addressing. The problem with DMX control of lasers is you're a bit limited in what you can do; professional lasers use a different protocol to allow sophisticated patterns and images.

Just take a battery operated discman with a compilation album in it.

I see, your CDG player has a 15 way VGA output socket. All I can say is, try it with the switch box. It may work. A VGA signal contains data called an I2C bus as well as the basic video signals. This allows the monitor to adjust its resolution & frequency to suit the source, unlike say a PAL tv signal which is fixed. The only issue you may have is that the laptop 'senses' when an external monitor is connected, and automatically reconfigures the graphics properties to drive the external monitor at the same time as the internal one. It also 'interrogates' the monitor via the I2C b

Not sure what you mean. A standard CDG player will be composite video (yellow phono lead) into a TV? Your laptop is you've said VGA into an external monitor. How do you display your CDG graphics at the moment?

the peavey are 4 ohm so will allow the amp to develop almost double the power of the kam 8 ohm speakers...worth bearing in mind if you're tight on budget or space. The difference will be noticeable.

shove the channel faders all the way up if you want, adjust the channel gains so the channel PFL meters are tickling red, then adjust the master to taste, avoiding the red on the master VU. Bear in mind the DJM600 also has a rear attenuator after the master fader, if in doubt, turn this all the way up for maximum leeway on the master. Worst thing you can do is have the speaker gains too low and then try and 'force' level through by over-driving the mixer. Normally a powered speaker will have a centre detent on the gain to indicate 0dB.

Yes, if you want, its the correct way

Looks like a power supply rail dropping out :flirt:
