DMX Sound-To-Light Processor (STLP)

A unique and innovative product that gives dynamic, engaging multi-zone sound-to-light effects to your lighting installation. Perfect for a small club, bar, gym or even a child's bedroom it opens up a world of possibility to your lighting scheme. It transmits DMX and SPI signals simultaneously, and there is a choice between WS2812 and LPD6803 SPI protocols.

In its simplest configuration the STLP has a number of standalone modes designed to match the mood of the venue. For instance the 'high energy' mode is a fast-moving range of effects. There is the option of blackout when the music stops or a heartbeat effect, see the video below:

Example of Standalone Mode (HighEnergy With Heartbeat when music stops)

It can either be used standalone or with an existing DMX controller. When used with an existing DMX controller the STLP uses the first 9 DMX channels to setup the mode and operating parameters. When the unit is switched off by the DMX controller it simply converts DMX to SPI, putting the original DMX controller 'in charge'. The DMX received by the STLP is converted to SPI, allowing SPI products such as dream striplights or downlights to be controlled, even when the unit is disabled through the DMX controller.

In addition to the sound modes, there are architectural features built in, so that when the venue isn't being used for parties normal lighting is easily achieved.

LED products such as dream striplights or SPI LED downlighters work extremely well with the STLP. Using the scale function, many thousands of SPI channels can be controlled. A customer of ours has installed an STLP into a party bus with two runs of 8m Dream LED strip down each side and has sent us the following video. Many thanks to Lucasz at

Sound-To-Light Project Idea 1 - MDF Ring

If the installation in the video below appeals to you here is how it was done.

The design is based around 'dream' flexible striplights fitted around the circumference of an MDF ring. These have 10 zones per metre that can be individually controlled. The circumference of the ring was a little over 4m, so a 4m length of striplight was fitted.

As the designer wanted to control the whole striplight from a wall controller, a multi-zone DMX controller was required that would cope with 40 zones of RGB = 120 channels. A Nicolaudie GU2 controller was chosen as it has 127 channels and is attractive and very easy to use and program.

As it was for a child's bedroom the designer included a wi-fi interface to an android app (not described here) This allows the parents to switch off the lights remotely at bedtime, or to set the lights to a very low level for a nightlight effect.

Sound-To-Light Idea 2 - VU Meter

The 'VU' meter concept is a very popular club type effect that looks good in a wide variety of installations. It is easily achieved by the use of SPI Flexible striplight and a Cromatix sound-to-light processor. As this is a standalone project no DMX controller is required. This type of effect is often built into the wall using timber and opal acrylic to diffuse the light, but in this instance the SPI flexible striplight is held in an aluminium extrusion with a frosted cover.

This type of installation is popular around dance floors, in gyms, games rooms, bars and children's bedrooms.
