AC Mains Circuit Size Requirements
Power requirements for the IP
™
-Six amplifier are rated at “idle”, 1/8 power (“typical” music
conditions), 1/3 power and maximum rated power. The maximum power current draw rating is limited
by the amplifier’s circuit breaker. Consult the specification sheet for the current that each amplifier will
demand. AC mains voltage must be the same as that indicated on the back of the amplifier. Damage
caused by connecting the amplifier to improper AC voltage is not covered by any warranty.
NOTE:
Always turn off and disconnect the amplifier from the mains voltage before making
audio connections. As an extra precaution, turn down the input attenuators while powering
up.
Cooling Requirements
IP-Six amplifiers use a forced-air cooling system to maintain a consistently low operating temperature.
Air is drawn by a continuously variable speed fan mounted on the back panel and exhausts through
slots on the front panel. The fan will remain inactive until the internal operating temperature rises
above 45°C. Make sure that there is enough space around the back of the amplifier to allow air to
enter.
NOTE:
If the amplifier is rack mounted, do not use doors or covers on the front or back
without pressurizing the back of the rack. Regardless of the type of rack you are using, make
sure that heated air can escape freely, and that there is no resistance to the intake of cool air
through the back grille. Intake and exhaust air must flow without resistance.
Hibernation
The IP-Six features Hibernation circuitry. Current draw and thermal emissions are at a minimum with
the absence of an input signal. Once a signal is present, Hibernation instantly restores the amplifier
to normal. Current draw specifications while Hibernation is active are included in specifications under
“Idle Current Draw.”
Thermal Emissions
The system installer or designer should specify system cooling needs. Refer to the specifications
appendix at the back of this manual for specific thermal emissions figures.
Input Module Connections
The input connector accepts balanced and unbalanced audio signals. For use with an unbalanced
source, tie the inverting (-) input to ground by installing a jumper to the signal ground connection. If
the inverting input is left floating, a 6 dB loss in gain will result.
