Zero88 Demux 48 - Lincolnshire


Description

The Demux 48 is a 48 channel freestanding DMX to Analogue converter. Manufactured to the highest professional standards, the Demux 48 offers users the ability to use legacy analogue equipment with more modern DMX512 controllers. It is possible to select individual analogue output sockets as either negative or positive control voltage (+/- 10V), for maximum flexibility. This is an immaculate looking piece of kit which has hardly been used and, although discontinued by Zero88 and replaced by the Demux 24(which only offers 24 channels), it is still a viable choice for digital to analogue demultiplexing in order to enable DMX512 control in theatres where analogue dimming equipment exists. If you are reading this, then you are most likely looking to replace a Demux 48 that you are already using.

This is a better choice than buying two Demux 24s to cover the 48 channels (the cheapest price I can currently find online for one Demux 24 is £459.84) or buying a cheaper, and less reliable, Chinese equivalent. A historical problem with the Demux 48 is battery leakage. I have had the device, and more specifically the battery, checked by an AV professional and I can confirm that there has been no leakage (therefore no damage inside the unit) and that the battery has been replaced so it is holding 100% life as of today. For those who are unfamiliar with this product, I am including the lines from the Zero88 spec as follows:

• The unit shall provide 48 channels of digital to analogue demultiplexing.
