Wireless Problems

[Joshbasscana]

Hey guys,

It might be just me and my thick skull. However, It might not be. I was bought the Ashton AWM200BP Wireless system for guitar/bass for Christmas. When I plugged it and played the signal degredation was pretty bad and was distorting a fair bit.

I took it back to the shop and had it exchanged for a better Audio Technica 700 series Wireless System. But I had the same problem! I tried everything. Changed all the leads, tried all the different channels, tried every combo of volumes on the reciever and with the bass. No success!

Is it my bass? I play a Bongo Bass which does have an 18V preamp - could this be the problem? I tried the wireless system with my Taylor and didn't seem to have any problems what so ever.
So is it my bass? Or is it something else? Input would be valued as this is doing my nut in!
Thanks guys,

Josh

you could be overloading the input stage of the wireless system with 18V pre from the bass.... I've come across this problem a lot.

I've never used either of these, but do they have input gain controls on the receiver ? You might need to reduce the gain to compensate for higher output.

This is what I thought might be the problem

The Audio Technia Reciever has an output volume control but whether turned down or turned to the max it didn't seem to solve the problem

Apparently the transmitter (not the receiver) has a "trim" control on the side. The manual advises as follows -

"For INSTRUMENT: While playing the instrument at typically loud
levels, check the AF peak indicator on the receiver. If AF peak
indicator is easily illuminated and distortion is heard through the
system, it may be necessary to adjust the transmitter audio input
level. To adjust the transmitter audio input level, gently turn the
instrument trim control counterclockwise until the AF peak indicator
is illuminated only on audio peaks"

Does this make any sense ?

Well I thought that was the problem. I adjusted it and it made no dofference. I even tried the "mic" trim which did nothing of course. Very fustrating.
