The ADJ Focus Spot 7Z is a high-performance fixture suited for multiple applications. For noise
critical environments such as Theater, Opera, or Orchestral Halls, it offers various fan operation
modes which remove unwanted noise distractions for the audience and performers. Fan 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 Fan Modes smoothly transition over a
brief period, preventing unwanted attraction to the fixture.
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, always, 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.
Note: Auto is the recommend mode for daily operation of
the ADJ Focus Spot 7Z.
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 – 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%.
