The AlphaCom/ACM exchanges came approx 1992 to replace the MPC/VMP exchanges , and they are still sold to day.
Note! After december year 2002 the factory production of service boards for the "Stentofon Touchline" series exchanges like "Stentofon Pamex / MPC " and "Vingtor Marine VMP" was history , but there are many of them still working perfectly and it's also possible to have these versatile and high quality exchanges repaired .
Read this page to learn how to make your Stentofon Pamex / MPC and Vingtor Marine VMP ( stentofon inside ) intercom system last several times longer.
Repairing Stentofon / Vingtor Marine intercom / related interfaces and Pa systems is a big part of our work , also by travelling to domestic and international destinations ( language : english / scandivavian ) . We have the knowhow , try us .
Extended system knowledge is neccesary to make a good programming job , also to best program "outdated" VMP / MPC systems .
******************************
In some environments, people using hearing aids are often disturbed by annoying electrical & magnetic noice .
The mobile phones most often use a current loop to send the speaker sound to the hearing device. On many costal ships and some other environments the electromagnetical noice is so annoying that this use of a mobile phone is impossible!
The best way to prevent electrical & magnetic noice is to kill it, at the spot where it is generated. Also use an electromagnetic hearing device to sort out the noice sources.
A well known electromagnetical noice source ! Equipment using a frequency inverter may need an extra Mains noice filter of good quality in front of the inverter. Note! The size of a proffessional filter could be similar to the the size of the frequency inverter itself. Sometimes an output noice filter from the frequency inverter also has to be used.
