Elvari is passive but still outputs a powerful signal. Active electric violins can interfere with electronics in wireless systems. In addition, heavy 9V batteries are needed which must be replaced before each concert. The built-in passive electronics in Elvari mean more reliability, and reliability is priceless in a live context. Wireless systems have an added advantage in that they make your Elvari active – if you need this.
