5.2.2. Mains supply
The table below indicates the number of devices per phase conductor
when full output power is required.
Mains supply Number of devices
230 V / 16 A Max. 4
115/100 V / 15 A Max. 2
In the USA and Japan we recommend the use of mains leads with a
high cross section (min. 4 mm
2
/ AWG 12).
5.2.3. Operating conditions
The following diagram shows the thermal operating range within which
the technical data will be maintained. The operation beyond this range
is possible for a short time and for thermal reasons this will trigger the
amplifier protection circuit into thermal overload.
Fig. 7: Average maximum total output power vs. ambient temperature
As explained in section 5.2.1, a worst case signal with a CF of 2.4 is
producing 1/3 of the rated sine output power or 200 watts at 4 ohms
per channel (400 watts total).
- The thermal management of the D6 is designed to deliver this power
for an unlimited amount of time within an ambient temperature of
up to 40° C (104° F).
- With higher ambient temperatures, the maximum average
output power that can be delivered without entering thermal
protection, is reducing linearly as shown in the diagram above.
- When using the D6 at its upper temperature limit of 45° C
(113° F), the maximum continuous output power is 340 watts total
or 170 watts per channel.
Again referring to section 5.2.1 - Tab. 4 - "D6 Power balance" - the unit
will work properly with e.g. 150 watts total when either
- running 4 ohms loads when the signal has a CF of 4.0
- or running 8 ohms loads if the worst case signal with a CF of 2.4
needs to be handled.
The maximum possible output power of 2 x 600 W at 4 ohms, which for
thermal reasons could only be supplied in short term (within minutes), is
unaffected by the ambient temperature.
