Ventilation
This may be as good a time as any to have
“the talk” about ventilation. The Pantages
G4 features cool-running efficient switch
mode power supplies and amplifiers but it
is still a very powerful five-channel ampli-
fier, and therefore requires plenty of good
clean, dry, ventilation to properly cool.
Please be advised that no more
than 2 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 specifica-
tions and ensure that your rack
room meets these requirements.
If the amplifier should overheat, a thermal
sensor will put it into standby mode,
allowing the heatsink to cool down.
Once the amplifier has cooled to a safe
operating temperature, the amplifier will
reactivate. If this occurs often, identify the
cause of the problem and take corrective
action, for example:
•
Provide additional ventilation
•
Do not install in a sealed
location with limited or no
airflow
•
Install a fan in the rack
•
Make sure that the amplifi-
ers are not overloaded with
speaker impedances below
the recommended minimum
•
Check that there are no
short circuits in the speaker
cables or speakers. Note:
Each channel will shut off
independently when a short
circuit is detected.
