Note 1): Automatic -6 dB gain compensation when bridging channels. Ch.'s A+B and/or C+D, E+F, G+H, can be bridged individually.
Note 2): 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.
Note 3): 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 V peak. Hence, outputs can be
set for high-impedance loads without requiring a transformer.
Note 4): Regarding n.r. (not recommended) notes: The amplifier will be fully operational in bridge-mode into 2 ohm and high impedance (Hi-Z) loads, but due to
physical constraints in the construction, the max. output power will not be significanty higher than running individual channels and therefore this mode of
operation is not recommended.
Note 5): C 88:4 mains connector: 30 A Twist lock.
Note 6): Separate 230 V or 115 V versions available. Not selectable on the amplifier.
All specifications are subject to change without notice.
