Alpha- 8 provides four pairs of outputs. These are optically isolated from each other and can be
standard 5 pin or 3 pin or 3 pin reverse. Internally, the circuit board carries spare IC' s enabling you to
get up-and-running again very fast in the case of an emergency.
Alpha-8 allow the DMX signal to be split without the possibility of reflections from one signal path interfering with the signal to a device on a different path. By isolating each output, electrical noise and hazardous voltages on one output are prevented from affecting ( or damaging) devices on the input or another output.
Common uses for the Splitter /Amplifier include: Plug the console or the unit to the dimmers or odher DAIX receive Alpha-sis normally provided with the conectan specified for DMMXS12:
Input-3 pin male "XLR" style Output-3 pin female "XLR" style The signals on each pin are:
1= Common
2=Data-
3=Data+
The unit may also be ordered with non-standand connectors such as 3 pin "XLR style. Note thai pin I is common in
name only. All commons are electrically isolated from each other OPERATION.
The Alpha-8 has no operator controls it is fully automatic I should be len plugged in st all times for isolated by the optical couplens, and retransmuitled by the driver cieuits All this takes less than 10,000,000 af a secood.
When no D MX imput is present, the outputs are placed in an idle condition. This conditinn ia defined in the DMX512 specification as Data line high and Data line low indicators are provided on the front panel of the splitier.
The red POWER Indicator is üleninaied ubenever the power cond is pluggnd into a live outlet. The green SIGNAL Indicator is illuminatesd wbenever the Datay and Data- Lines leave their idle tate. Note than the signal indicator does not necessarily indicate a Valid signal, anly thai the line is not idling.
The signal indicator will change intensities as the levels sent to the outputs varg In some cases the signal indicator may be quite dim even though data is being received. The indicator will be at its owest intensity when all dimmers are being sent to full Try sending all dimmers to zero then look at the indicator .SPECIFICATIONS
