Wireless System, No More Signal Drop!

As we know, SEM-02 supports a wide range of wireless systems, from Fifine to Sennheiser using a special adapter. The adapter can be seen here.

With the support feature for the wireless system, we got a lot of positive responses. Wireless systems do have the advantage that we can move more freely. Nice indeed?

But…

It’s not that the wireless system has no weaknesses, signal loss is one of the weaknesses of the wireless system.

Indeed, there are tiers in wireless systems, from entry-level ones ranging from under 100 USD to above 1000 USD. However, even wireless systems with higher specifications cannot escape the risk of signal loss/signal drop caused by signal interference by other tools/devices.

Here are our tips to reduce the risk of signal lost/signal drop:

1. Set the frequency of each wireless transmitter

UHF wireless systems rely on radio waves for transmitting audio signals both digitally and analogously. For this reason, we must set the frequency on the wireless system at least so that it is not too close together, for example on the Fifine K037 wireless we give a distance of at least 3 steps as shown in the following figure:

We suggest that the device has at least a free space for transmitting the signal, because any frequency must have its harmonic frequency as well, and we can anticipate one of the ways above. In addition, the risk of channels piling up on one frequency is also reduced.

2. Keep away from wireless devices (smartphones, wifi routers/ repeaters)2.

Some modern wireless systems use the 2.4 GHz frequency band, for example Rode Wireless Go, Saramonic Blink, etc. The bad news is, this frequency band is also used by bluetooth, wifi/routers, even our smartphones and of course this frequency is very crowded! For that, when operating a wireless system with a frequency band specification of 2.4 Ghz, make sure not to get too close to the router! And.. put your smartphone away!

3. Cut the distance between Receiver and Transmitter

The wireless system is not a magic device that can transmit signals over hundreds of meters without obstacles. Then what does it mean? Well… when on stage most of us would think of placing a receiver near the FOH. Hmm.. that’s fine, but that’s not the right decision.

The best way is to place the receiver next to the stage, then connect the receiver to the FOH mixer with an XLR/snake cable. Remember that cables transmit audio signals better than air.

That way the distance and obstacles faced by the wireless system signal transmission will be shorter, which means GOOD SIGNAL, GOOD SOUND!
