[B][QUOTE]我还没有见过不标明负载阻抗条件的(最大)额定输出功率的表示方法.. [/B]
这是高文【Goldmund】的技术资料。
Technical Data.
Power
Nominal continuous power :
2 x 200 W RMS (2 - 8 Ohms).
2 x 100 W RMS (1 - 16 Ohms).
Maximum instantaneous power : > 2 x 400 W
(8 Ohms - 10祍 pulse - 10% duty cycle).
Maximum voltage swing : 62 V peak.
Maximum current swing : 28 A peak.
These figures for both channels driven simultaneously.
GOLDMUND DATASHEETS
Frequency Response
These figures are valid for the amplifier circuit aloneloaded
by 8 Ohms and working at any level between 0
and nominal power.
+/- 0.1 dB, 0 - 300 kHz, +/- 1 dB, 0 - 800 kHz.
+/- 3 dB, 0 - 2 MHz.
Input Sensitivity
Nominal level : 1.45 V RMS.
Voltage Gain : 28.2 (29dB).
Input impedance : 52 kOhms. Group Delay Grounding
Semi-floating chassis connected to mains earth. Propagation delay < 140 ns stable with frequency
from DC to 2 MHz. Switch for optionally connecting signal ground
to chassis ground.
Distortion
Figures valid for all levels from 0 to 26 V / 8 Ohms : Safety Features
AC voltage fuse : min 16 A slow-blow. Dynamic : TID < 0.01 % (- 80 dB) unweighted.
Static : THD < 0.01 % (- 80 dB) unweighted.
