Foldback Units Mk 4

Foldback Units Mk 4  
   
 
   
   
     
  We apologise profusely for keeping you waiting so long for our new, Mark 4 version of our popular and highly successful 863 MHz Foldback System (as you probably recall, we were forced to stop production of the previous version due to some essential parts becoming unexpectedly obsolete about eighteen months ago)

Thankfully, although it has taken a while, we have now found highly suitable replacements and after a complete re-design, we can now offer you our splendid new

 
     
   
     
  The standard supplied frequency is 863.625 MHz but it will be possible to supply three other channels to special order
ie:  863.125   864.500   and   864.875
all four frequencies can be used at the same time

The new Mk 4 863 Foldback system is mono, as most of you told us that you would prefer to have a mono than a stereo system

With the Mk 4 units, practically every (particularly with the Receiver) is now plug-in for easy replacement - no soldering required - so you could fix things in the field yourself without having to return the unit to us for repair

Mk 4 UHF 863 MHz Foldback Transmitter
is much, much smaller (by almost a third) and lighter than previous versions, which the inset photo proves:
Is that amazing, or what?

Despite the fact it has shrunk and lost weight, the new Transmitter is housed in a very robust die cast case with a tough, attractive black crackle-finish with nicely curvaceous corners

Although the system is mono, you can still feed stereo or 2 track mono (or left or right channels) into the Transmitter and it will combine the feeds without combining the original signals

As before, the unit is powered from 12 Volts via a Hirose 4 pin socket and we have (very thoughtfully and generously, we think) given you a second Hirose 4 pin socket to daisy chain power to other equipment

 
 
Audio quality is, we reckon, our best yet - probably too good for most Directors!  A 2:1 compander achieves a 100 dB dynamic range - absolutely no background noise
 
     
  The aerial is our well proven short rugged, high performance design with BNC connection   The power switch is a short toggle with cyan LED indicator  
         
  An adjustable modulation level control allows you to set the Transmitter up precisely for your system   No need for a separate Power Booster with the Mk 4 Transmitter!  
         
  And probably the best news is that, despite all these new advantages and new small size, the price remains the same as before:

is powered by a single PP3 type battery and the power switch is again our popular short toggle with a cyan battery level indicator

 

Mk 4  863 MHz Foldback Receiver Volume Control (copyright Black Box Video)The volume control is a very high quality knurled knob machined from solid metal - positioned on the side of the unit for easy use (so much better than the previous push button switch)

 
         
  Headphones connect via a standard stereo mini jack, giving mono sound in both earpieces   A red LED shows carrier being received OK

  The short, robust aerial connects via a BNC socket    
         
  The whole unit is housed in a robust yet lightweight die cast case with sexy rounded corners and a tough, attractive crackle finish  
     
  As with the new Transmitter, we are sure you will be pleased to learn that we have been able to provide these improvements at the same price as before
