FAQ's 

(and some not so frequently asked Q's)

bullet

I use a Sony 700 WAP camera.  Which socket on my camera does the Video Sender Transmitter plug into?  I only ask this because the TEST OUT socket which only displays the time code will already be used for my main monitor for the PA;  the Director does not need the time code, so does the Video Sender Transmitter work from VIDEO OUT?

bullet

How is the Video Sender Transmitter powered?  Is it from camera batteries, or an additional source?

bullet

On the Video Sender Receiver, is there an audio socket on the unit for headphones so that I can listen to what is going down on the tape?

bullet

Can you clarify the range of High Power Video Senders in metres (both direct line of sight and within a built up environment)?  And what difference does the Yagi aerial make?

Do the Video Senders use PLL frequency synthesis circuits?

How can I use your High Power 2.4 GHz Video sender Transmitters if they're unlicensable?

I would be very interested in using your Video Sender with an LCD Monitor, but why is the Transmitter so big?  And would you be able to make a Video Sender Transmitter integrated into a PAGlock bracket, on the back of a camera, with its own on & off switch - and could it only be turned on if the camera is turned on?  Maybe it could also be removable so it could be used with a minicam?

I use a Sony 700 WAP camera.  Which socket on my camera does the Video Sender Transmitter plug into?  I only ask this because the TEST OUT socket which only displays the time code will already be used for my main monitor for the PA;  the Director does not need the time code, so does the Video Sender Transmitter work from VIDEO OUT? You can use either the video TEST OUT, or the VIDEO OUT.  It depends on whether you want to see time code or not.
How is the Video Sender Transmitter powered?  Is it from camera batteries, or an additional source? The Video Sender Transmitter is powered from the camera battery, either by a HRS4M-HRS4M lead, or we can make you a HRS4M-PAG BP90 lead, or even an Anton Bauer Powertap.  In The Package we supply the standard HRS4M-HRS4M.  It is worth pointing out that you should check that the fuse in your Sony 700 WSP camera can supply 170 mA.
On the Video Sender Receiver, is there an audio socket on the unit for headphones so that I can listen to what is going down on the tape? Yes, there is an audio line-out socket and you can plug a headphone amplifier into it.  We can supply the amplifier for £25.  See our Video Sender page for full details and photos.
Can you clarify the range of High Power Video Senders in metres (both direct line of sight and within a built up environment)?  And what difference does the Yagi aerial make? The expected range - line of sight - of the High Power Video Senders would be approximately 300 metres.  However, using the Yagi aerial outside, the range would increase to approximately 700 metres line of sight.

The Yagi aerial is not really intended for indoor use, although this does not prevent you experimenting - but the results would be highly unpredictable.  See our Video Sender page for details of the Yagi.

The expected range in a built up environment would be approximately 100 metres, but this is only a rough guide and it is partly dependent upon the construction of the buildings.  There are also many other factors involved, such as whether there are human beings present and if so, whether they are moving around, the presence of computers, the presence of mobile phones, etc.  The list of "other factors" goes on and on!

Do the Video Senders use PLL frequency synthesis circuits? The Video Sender Transmitter uses a frequency synthesiser circuit, and the Receiver uses Phase Lock Loop circuitry.

Carrier channel frequency is selected on both the Transmitter and the Receiver by a click-stop channel selector control;  there is no requirement to fine-tune either the Transmitter or the Receiver as the frequencies are digitally selected.

Why don't you make the PP3 Battery Box anymore? Because so many people have asked us this, we now do offer this super little box again.  See our Power page for details.

How can I use your HP 2.4 GHz TX if they're unlicensable?

Although the High Power Video Sender units are not presently licensable in this country (UK), there are countries in the world where they are completely legal, such as Germany.  Licensing regulations change all the time and they may well be licensable in the near future (for instance, look at the 863 MHz and 433 MHz recent changes allowing much higher powers.

Our standard Video Sender (ie the Single and Five Channel units) are completely legal and license exempt in the UK - it is only the High Power version that is not yet licensable.

As a responsible company, Black Box Video would never condone breaking these regulations.  However, many of the High Power units we sell are only destined for use abroad where the higher power is legal, so there is no problem.

I would be very interested in using your Video Sender with an LCD Monitor, but why is the Transmitter so big?  And would you be able to make a Video Sender Transmitter integrated into a PAGlock bracket, on the back of a camera, with its own on & off switch - and could it only be turned on if the camera is turned on?  Maybe it could also be removable so it could be used with a minicam? Big!  Call that "big"!  There physically has to be enough room to put the input/output sockets and switches and the TX module into the box,  so it would be impossible to make it smaller.  (After all, its not a Tardis!) It is already a very tight squeeze in that there box!  And, unlike most rival units, our TX also incorporates a fully regulated power supply, hence giving it a large input voltage range of 9-36 Volts.

To integrate the TX into a PAGlock bracket would put the cost through the roof! and this would restrict its use to only PAG powered cameras.

The Video Sender uses microwaves - does that mean it could be dangerous?  Could it fry your brain? No, don't worry, it won't fry your brain.  The power output of our standard unit is only 10 mW, which is less than the leakage from your microwave oven which also uses the same frequencies.  It is also a fraction of the power of your mobile phone.
How many walls will the Video Sender go through? This is really an impossible question to give a definitive answer.  It will travel through light walls with some attenuation, but depends how thick the walls are and what they are made of.
How many of the five channels on the Video Sender are useable? You must have a minimum spacing of one clear channel, so the maximum number of channels you can use is 3 (ie channels 1, 3 & 5, or channels 1 & 5).  For best results you should always use the maximum spacing between channels.
What is the best way to store The BIG One? Store “The BIG One” upside down, particularly for long periods, as this allows the gel electrolyte to gradually settle to the bottom of the cells.
Should you store The BIG One charged or empty? Don't leave The BIG One in a part charged state for extended periods.  You should charge the unit fully before storing it.

Unlike Ni-Cads, The BIG One will hold its charge for many months.  Well over 90% charge is retained for over 3 months.

You should charge the unit fully at least once a year.

Is the new Mk II 863 MHz Directors Foldback system compatible with the original version? Sorry, no it is not.
What about the original Power Booster - is that compatible with the Mk II 863 MHz Directors Foldback system? Yes!!
Why have you stopped making the Power Distribution Box? We stopped producing this simply because it was uneconomic.  The cost of all those Hirose sockets and the time it took to build the box left us with a profit of about £1 a unit!  In addition, everyone wanted it customised - add this, add that, take away this.  It just could not be done for the price.
How does the Pearl MSH10 compare to the Pearl MS8 in terms of suck? Whilst it is not as tight as the 416, the MSH10 is a lot tighter than the MS8 - similar to an RSM191 but at less than half the price.
