Measuring Standard

0 dBu = 775 mV (RMS)
A.

POWER SUPPLY

1. voltage supply
2. nominal supply voltage, depending on the model:
3. nominal mains frequency:
4. nominal power consumption (2x800W/4Ω):
5. nominal power consumption (2x80W/4Ω):
6. power consumption at 1/8 of the nominal power (100W/4Ω):
7. power consumption at 1/8 of the maximum power:
8. deviation range of the power supply:

With the CPS-version, the input sensitivity is referenced to the maximum output power at 8Ω ,
which is 1Vrms when the jumper is set to 0 dBu.
Maximum input level: +21 dBu
C.

OUTPUT PROPERTIES

• nominal output power with THD = 0.1 %, 20 Hz ... 20 kHz, MBW = 80 kHz
• maximum output power at 1 kHz with THD = 1 %, MBW = 80 kHz
