The thing is, with LED lighting, each light can put out multiple colours. Therefore, much less lighting is actually required, so it is relatively cheap. Loudspeaker technology has not really changed, so not a lot really required there. Modern amplification is Class “D”, which is cheap compared to the Class “AB” of 20 years ago. Wireless microphone systems are quite expensive, I’ll admit, but not eye watering. So, where is the 1.6 million going?
