VORTEXS I LV E R SE R I ESUSER MANUALVORTEX SILVER SERIES V8P.123.3.2 Inrush current limitiationThe V8 has a special processor dedicated to limit the mains inrush current.This limiter will take action anytime:– when connecting the amplifier to the mains through the mains cable– when switching the amplifier on through an external mains breaker– the mains voltage was lost for at least 4 half-cycles or more (e.g. a shortvoltage drop)This limiter will confine the mains current to a value smaller than 17 A rms *.*: maximum rms value of inrush current over one half-cycle of the mains voltage according to DIN EN55103-1.NOTE: Even under normal conditions the mains current can reach levels upto 32 A / 64 A (230 V / 120 V) and even higher for very short periods of time.This could cause lamps to flicker if connected to the same mains as the am-plifier. The impedance of the AC circuit should be less than 0,157 Ω to avoidflicker according to EN61000-3-11 “Electromagnetic compatibility – Part 3-11: Limits – Limitation of voltage changes, voltage fluctuations, and flickerin the public low-voltage supply systems – Equipment with rated current ≤75 A and subject to conditional connection”. If in any doubt, consult yourlocal power provider. Never attempt to measure this impedance level withyour ohmmeter. This may damage your meter and expose you to the riskof electric shock!3.3.3 Mains power consuption and current drawDue to the huge output power of the V8, the mains current draw can getvery high when demanding large output powers. Please refer to followingtable for an overview of mains currents and power cunsuption under differ-ent operating conditions.Operating condition Mainscurrent(4 Ω / 2 Ω)Powerconsumption(4 Ω / 2 Ω)OutputpowerAmplifier standby (power off) < 0,4 A 8 W 0 WIdle (amplifier powered on) 1 A 60 W 0 W300 W per channel 8,4 / 9,2 A 1120 / 1250 W 600 W600 W per channel / th 13,4 / 14,9 A 1930 / 2150 W 1200 W1200 W per channel* / th 22,4 / 25,3 A 3360 / 3830 W 2400 W1600 W per channel* / rd 29,4 / 32,3 A 4570 / 4950 W 3200 WMains current draw and power consumption @ 230 V, 50 HzMeasured with pink noise with crest factor of 12 dB to represent typical music signal.For 120 V mains operation, the current values can be multiplied by 2.*: duration limited by FuseProtect limiter (set @ 24 A)Please note that the values given here are typical values only, measuredon a standard 230 V / 50 Hz outlet. The actual mains current draw can varydepending on the music signal and the mains characteristics (especiallythe mains impedance) of any specific installation.The integrated FuseProtect limiter will limit the average mains current drawto values between 24 A down to 8 A (selectable in 1 A steps).This allows to control the average (long-term) mains current draw of yourinstallation, while at the same time guaranteeing full power headroom fordynamic music signals.This means that even if the FuseProtect limiter is set to low average values,the short term mains current draw can still reach very high levels, espe-cially when delivering huge output power with very dynamic music signals.Please see chapter 4.6.5 for more information on the FuseProtect limiter.3 INSTALLATION
