Many "dimmable" LED bulbs work ﬁne with the Shoeboxes (though it's common for them to

only dim to about 10% before turning completely off which can be disappointing), and the

percentage of those in the market continues to increase with time as bulb manufactures

improve their circuitry's compatibility. Still, some LED bulbs will ﬂicker at low power levels.

There are a few approaches to dealing with these bulbs: The easiest is to test several

different bulb models, and just avoid the trouble makers. Some control consoles can be

programed to avoid the problematic low power levels. In some cases, the ﬂickering can be

mitigated by adding parallel loads in the form of a low power incandescent bulb or resistors.

Dove Systems offers factory installed 4.7kΩ output resistors by special order or retroﬁt.

On the DM412-WM, there is one terminal for each output and two larger output neutral

terminals. On the DM124-WM, there is one output terminal and one output neutral terminal.

Terminals are labeled according to their circuits, see photos above. There should be a

separate neutral returning from each load circuit.

Each output channel is protected by a 10 Amp circuit breaker (20A on the DM124). If a circuit

breaker trips, it is generally due to an overload or short in the output load. However, elevated

ambient temperatures or lack of ventilation can also result in breakers tripping just shy of their

rated current.

Control Terminal Block (Neon Power Indicator option shown)

The pack accepts both DMX-512 and analog 0 to +10VDC control signals. DMX control

signals are input through the ﬁrst three terminals (Common, Data-, and Data+) of the 12
