5.2.2. Mains supply

The table below indicates the number of devices per phase conductor

when full output power is required.

Mains supply

230 V / 16 A

115/100 V / 15 A

In the USA and Japan we recommend the use of mains leads with a

high cross section (min. 4 mm

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. 6: 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. 3 - "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.
