Finish Black painted steel chassis with gray painted steel front Approvals CE, ANSI/UL 60065 (ETL), CSA C22.2 NO. 60065, FCC 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 highe\ r than 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): 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.
