The Artiste Rembrandt is a high-performance fixture suited for many applications. For noise critical
environments like Theater, Opera or Orchestra Halls, it offers various operation modes to remove any
distraction for the audience and performers. Modes can be changed remotely via the DMX control
channel, allowing the fixture to offer high output or whisper silent operation at a moment’s notice. All
modes smoothly transition over a brief period, preventing unwanted attraction to the fixture.

Fan Modes
Auto
– The default AUTO mode ensures optimal performance of the fixture. Fans only run at the
speeds needed to keep the LED engine within a safe temperature range. They will turn off if possible,
for example when the fixture is dimmed to a low intensity. Fans sense the ambient and fixture
temperature, and will at all times try to keep noise levels at a minimum. The fixture output will only
reduce when the LED engine cannot be cooled down to its safe operating range due to high ambient
temperature.
Auto is the recommend mode for daily operation of the Artiste Rembrandt.
Low
– In this mode the fixture reduces fan speeds throughout for a lower noise profile of the fixture.
This mode should be sufficient for most uses where lower noise is required. The fixture output is
reduced to about 80%.
High
– This mode is only required in very high ambient temperatures when automatic fan speed
adjustments are not desired. High Fan Speed will cool the fixture most efficiently. This mode will
increase wear on the fans and should only be utilized in exceptional circumstances. Fans will always
run, even if the fixture is dimmed. Fixture output is kept at 100% unless the LED engine temperature
is too high, at which point the fixture will reduce power carefully to ensure safe operation.
Low Noise Modes
For very critical situations, the Rembrandt offers two additional low noise modes for silent operation.
The fixture output will be reduced, but as the Rembrandt has such an extremely high luminous flux, it
still offers outstanding performance. In low noise modes, all parameters of the Rembrandt operate
quieter and with reduced speeds.
Studio
– This mode reduces the fixture output to approximately 50%. Almost all fans inside the
Rembrandt are turned off, and only run when absolutely necessary to keep the fixture at 50% LED
power.
Mute
– Running the fixture in MUTE mode reduces the fixture to about 25% output, and all fans are
off. The fixture is totally silent.
