Thanks to all our customers we continue to spread PLUS1’s around the world. And we keep continuing adding new features like DAB MER, remote streaming and EMF. The MER functions indicates the signal power vs. error power. The PLUS1 streamer option is standard now with no extra cost. Enjoy remote listening by pushing a button at the GUI on your Apple, Android (and others) device! This enables full remote monitoring of your valuable audio content. The option device clock mode is added to add the manual clock mode if no network is available. This extra is also added in the WebGui.

PROFline repair service

In the rare event that a PROFline unit is no longer working as it should, bring it in for repair. The PROFline team can offer repair service for all legacy PROFline products. For a variety of customers we recently serviced SFD, SFP, STR en SDV’s. We do offer repair after customer approval so no surprises and you will be quoted upfront.
Our equipment is that good that we have units from 20 years old that only have had minor problems with the supply that will be renewed.
Never the less it is wise to renew your equipment on a earlier date, or send it back for a maintenance service to be sure it will work for several years again. We will renew the supply and give the unit a full service and check of all the parameters are working properly.

Small Scale DAB TX

We have promised you an update…. Currently our RF designer is developing the powerstage of our transmitter. Up to 20 Watts clean power with adequate DAB shoulder and no RF spurious is the goal. The world is changing to DAB+ and we are too. The small scale dab transmitter will be showcased soon.

We also have a DAB MUX ready that works with a normal PC and DAB MUX software, it even have a normal audio input for local insertion, the idea is that it will be a product for tunnel emergency equipment as our legacy products are used for every where in Europe

For Tunnel DAB transmission we use a low power DAB modulator that will be a part of the RF signal chain in the tunnel with all the other RF signals like FM, DAB and hand held equipment for emergency use
