Note 1): Regarding n.r. (not recommended) notes: The amplifier will be fully operational in bridge-mo\
de into 2 ohm and high impedance (Hi-Z) loads, but due to physical constraints in the
construction, the max. output power will not be significantly higher th\
an running individual channels and therefore this mode of operation is not recommended.
Note 2): For sine waves, peak voltage output values translate to Vrms with the formula V/1.41 = Vrms. E.g. 100 V peak equals app. 70 Vrms. Hence, outputs can be set for
high-impedance loads without requiring a transformer.
Note 3): Automatic -6 dB gain compensation when bridging channels. Ch.s A+B and/or C+D, can be bridged individually.
Note 4): Separate 230 V or 115 V versions available. Not selectable on the amplif\
ier.
Note 5): PAL can reduce the maximum output power to keep the power supply operating safely\
, and/or to prevent excessive current draw tripping the mains breaker.
Refer to Operation Manual.
