Dear All,
I was asked to help at a wedding by providing the audio system for the
ceremony. I was also going to record it. It didn't go as planned. I thought
that somebody here could explain what went wrong.
-- I have a pair of Boaz dual range portable speakers. In the high range
they are very loud, loud enough for the hall. Not the problem, I think.
-- I plug the speakers into my laptop headphone jack, plug in a wired mic,
and go into accessories/entertainment/volume control, select the options to
show both playback and recording. I then unmute the microphone.
-- OK, standing 2 meters behind the speakers, all worked well.
-- I purchased a Radio Shack wireless mic and it came with a wireless
receiver and antenna. It was $50 US. I tested this at home and here too all
seemed well. It seemed that the squelch on the receiver did not do much. I
could only have the volume on the receiver fairly low before the feedback
started to scream, but even with low volume on the wireless receiver the
speakers put out plenty of sound, even outside; standing outside 25 meters
away, the sound was fine.
-- When I went to the hall to set up, all went to Hades. I had the speakers
set upabout 3 meters in front of the wireless mic. I tried all combinations
of volumes in volume control for both the loudness and the microphone
levels. Working on the receiver with the squelch still did not do much and I
had to keep the volume on the wireless receiver very low, too low to provide
much sound out of the speakers. So, I don't know what happened between the
testing at home and at the hall.
Thoughts welcome; perhaps this is wireless mic basics.
Best
George
