There is not much one can say about Tone Generators. They can be turned on, they can be turned off, where that is about it. Most importantly is that when they are turned on they will add a tone signal, at a given frequency, into your LNB cable.
This on/off switch can of course be done automatically with a receiver with two LNB inputs, or a 0/12v switch, or manually using the front switch, or by remote control.
The most interesting thing about Tone Generators is what functions you can gain when you add one, when once correctly installed they will become quite boring and you would hardly notice that they are there at all.
Global 22kHz Tone Generator
This device is most useful to those people with an old satellite receiver wishing to make use of a new Universal LNB. As lacking a 22kHz tone option would mean that the Universal LNB could not switch to it's 10.6 Ghz L.O resulting in only being able to access half of the available frequency range. And so with this device the Universal LNB would switch from the 9.75 to the 10.6Ghz L.O when the tone signal is enabled.
Apart from that this device could also be used to control an external LNB switch or other devices that require a 22kHz tone signal to be able to switch on and off the desired function.
The lead going off the top right hand corner in the photo is used for the automatic switching function. On the very end of this lead is a scart plug that makes use of the 12 volt switch control, from pin 8 of the scart socket, found on most satellite receivers. However, should your required scart socket already be occupied, or if you have a seperate 12v switch, then this lead allows the scart plug to be easily pulled off, revealing a single scart pin that can be jammed where ever you need it.
Should your receiver lack a 12 volt automatic switch, then the second option is to use both the Rx A and Rx B inputs, should your receiver have a two LNB input instead. When the Rx A input is in use, then no 22kHz tone will be generated. However, when the Rx B input is in use, then a 22kHz tone will be sent down the cable.
If you lack both of these switching methods, then so can the on / off switch on the front of this model be used for manual switching. So no matter if your receiver is the best or the worst model on the market, then this device can provide the 22kHz tone switching that you need.
Apart from the switching, then this device also includes a single F-Lead. This will be fine if you plan to use the 12 volt switch option, but for the two LNB input switching option, then you will need a second F-Lead. You can see my FLEAD on the Cables (Audio/Video) page should you need one.

Global 60Hz Tone Generator
If I just said that this model was exactly the same as the above GEN22+ model, with a 60Hz output instead of a 22kHz output, then that would sum up this device to a level that any box shifting commercial supplier would be happy with. However, if I just did that then that red bar you see below would slide half way up this photo. And so to put that red bar in the right place, not to mention to provide my usual level of detail, then I now have to repeat all the above information as well as add in a small history lesson about this device.
Starting with ye olde history lesson first, then during the ancient age of satellite TV reception, where most of the people reading this text would have been alive during this time, then the question soon arose of how a satellite receiver can swap between two LNBs without having to lay out another cable run. And thus the 60Hz tone generator was born as the very first method to switch between two LNBs.
It is worth noting that 22kHz tone generators were later created to perform this very same function, when this 60Hz switching later moved into switching the L.O of the old LNBs, which added the need to once again create a tone switch to now switch between your two LNBs with the 60Hz L.Os. And as history has since laid down; then the reduction in popularity of 60Hz LNB switching system meant that now the 22kHz tone signal took over the job of the L.O switching on LNBs, like with the now common Universal LNB.
The most important aspect to keep in mind here is that both the 60Hz and 22kHz tone signals were designed to work together down the same LNB cable. And now that the 22kHz tone signal rules the world of the Universal and other LNBs, then that means that the 60Hz tone signal is now free to control other devices, like with the ideal LNB switch.
And so if your receiver lacks the DiSEqC LNB switching function, which even many new satellite receivers do in order to reduce the production cost, then to go one up on the more basic on/off power switcing method of my LNBSW device, then why not put this 60Hz tone switching system back to it's original use?
In case I do not yet stock the 60Hz LNB switch device, and forgot to remove this text when I do, then just ask for one, when then I will quickly get them in stock.
Now that you know that this device could well be the ideal solution to your LNB switching problem then now I will cover just how this 60Hz tone can be turned on and off.
The first and ideal method is to make use of the pin 8 of the scart socket option, when just about every satellite receiver around should have a 12 volt switch option. And to make for easy pin 8 connection, then this device comes with a detachable scart plug. Should your scart socket already be occupied then that is no problem, where you can just pull off this scart plug to reveal the specially designed pin for this task. And so by your method of choice you should remove pin 8 of your existing scart plug, when it won't need it anyway, then to push this single pin into pin 8 on your scart socket, before pushing in your regular scart lead behind it. Should your receiver support an independent 12v switch, then you can use that instead.
The second switching option is to use the Rx A and Rx B inputs. So if your receiver supports twoLNB inputs, then connecting both of these to this GEN60+ device, with the aid if my FLEAD if you need a second cable, now allows easy 60Hz switching just by selecting your LNB input.
And in case your receiver lacks both these switching options, then that explains the on/off switch on this device to provide manual switching.
So if this is the ideal device to switch between your two LNBs, or to control other 60Hz switching hardware, then here now is my price. I should mention that since Global charge me 61.47% more for the GEN60+ over the GEN22+, then that explains my own comparable price difference between these two tone switches.
