Installation Notes
• Ensure that rack or other confined installation does not
restrict the airflow required for safe and reliable operation of
the equipment. It is important to ensure that the 40°C maximum
operating temperature for the equipment is not exceeded.
• Amplifiers will not switch on from standby mode unless an input
signal is present or the standby switch is toggled.
