Q. The desk top PC I use for
presentations only has one monitor output and I wish to connect the monitor and
the projector at the same time
There
are two ways of achieving this:
If the cable run from the PC to the projector is short, purchase a VGA
distribution amplifier like the Kramer
Tools VP-200N and a short link lead. You will need an extra mains point for
the plug top power adaptor supplied with the distribution amplifier. You can
order a mains distribution board from us to add an extra 13A socket if
necessary.
Buy a new video card for your PC with two outputs and Dual screen
functionality. This option will enable you to take full advantage of the
Presenter View facility within PowerPoint 2003/2007
Recommended video cards include nVidia and Matrox
The card is probably best fitted and configured by a technician. If your PC is
covered by a contract your IT supplier will undertake this work, alternatively
we will be pleased to quote you to install the card and any associated
equipment and cabling.
Q.
We have a PA system installed in our meeting hall and wish to connect the sound
from a laptop into the system. The only connections available are microphone
sockets. Can you supply a cable to enable us to make the connection?
Not so simple as that, I am afraid. Microphone signals are low
level signals and the amplifier input is very sensitive. The output from a
laptop sound card is high level and if you did make the connection, it would be
badly distorted and probably damage the amplifier.
We would recommend a DI box which attenuates the signal from the laptop to a
level that is acceptable to the microphone channel on the amplifier.
Our laptop interface kit contains the DI box, a colour coded microphone lead
and the laptop to DI box lead.
A: Almost certainly the induction loop system.
You will probably find that the loop cable runs in close proximity and parallel
to the computer graphics feed cable to the projector. To prove if this is the
cause, play a music source through the induction loop at a fairly high level
while the projector is showing images from your usual source PC.
There
is a temporary work round and two solutions:
1.
Switch off the induction loop amplifier during any music but
please explain why you are doing this to any member of the congregation who
uses a hearing aid. Do not adjust the induction loop amplifier.
2.
Moving the cables at least a metre apart should also solve the
problem but may not be practical due to the layout of your building
3.
If the only cable route available is adjacent to the induction
loop, buy one our fibre optic cable kits. This method uses light to transmit
the signal from one end to the other and this is not affected by the
electro-magnetic waves generated by a loop system.
If
the induction loop is not the cause of the problem, please contact us.
