Ventilation - AudioControl Director M6800D Installation Manual

Ventilation

The Director M6800D features cool-
running, efficient switch mode power
supplies and Class D amplifiers, equipped
with thermally controlled fans. As
high-powered 16-channel amplifiers,
proper ventilation is required to maintain
sufficiently cool operational status.
Please be advised that no more
than 4 Director models may be
stacked together. Any more than
that, then a rack space above and
below is required for adequate
ventilation.
Review the heat load specifications
and ensure that your rack room
meets these requirements.
Ideal Spacing 1U rack space or more
above and below each pair

If the amplifier should happen to overheat,
a thermal sensor places it into standby
mode, enabling the heatsink to cool down.
Once the amplifier has attained a safe
operating temperature, it will reactivate.
If this occurs often, the cause must be
identified and corrective action taken.
This may include:
• Additional ventilation
• Ensure the installation location does
not have limited or no airflow
• Install heat extraction fans in the
rack, or the installation location
• Determine if the amplifiers are
overloaded by speaker impedances
below the recommended minimum
• Inspect speaker cables and speakers
for signs of short-circuiting.
Note: Zones shut off independently when
a fault such as a short circuit is detected.
No more than four units can be stacked
without a rack space between them.
Allow 1U rack space or more above and
below each stack of four.
