Powersoft Quattrocanali 4804 DSP D 4800W/4-channel Flexible Amplifier with DSP and Dante

Description Quattrocanali 4804 offers the traditionally amazing sound quality and reliability of all Powersoft products.The patented SRM (Smart Rails Management) technology allows to maximize the efficiency of the system and drastically reduce power consumption in any load and usage condition. Quattrocanali features the lowest thermal dissipation in the industry, reducing the need for external cooling devices.Quattrocanali is designed to operate with Lo-Z (from 2 Ω) and 70V/100V distributed lines or any mix of the two.DSP D versions of the Quattrocanali grant in-depth control and monitoring via Armonìa, tailoring the sound and managing the system can be done by a remote, decentralized location.This Amplifier Platform can also be trusted in mission-critical applications, such as fire alarm systems, thanks to the cleverly engineered power supply that allows reliable operation even when connected to a UPS.Features of Quattrocanali 4804 DSP DPower supplyPatented output filter with ripple cancellation networkLow Inrush Limiting reduces AC inrush current, removing the need for expensive power sequencersDetachable AC mains cable with IEC C19/22.2 (16A for EU, 20 A for USA) socketProtectionsFully protected circuit design with:Ac protection: shut down power supply when AC mains voltage is outside operating rangeClip limiter: prevents severely clipped waveforms from reaching loudspeakers, while still maintaining full peak power outputDC protection: protects against infrasonic signal at the outputsVHF protections: protects the loudspeakers against non audible, strong, non musical high frequency signalsShort circuit protection: protects the amplifier from short circuit or other stressful events for the output circuits with automatic protection resetLong term limiter: protects the loudspeaker against steady long term RMS (non audio) signals, by reducing maximum outputThermal protection: output stages operating temperature up to 80 °C (176 °F)Temperature controlled continuous variable speed fan, front to back airflowTemperature forecast with LCD traced historical behaviorGeneralFixed frequency switch-mode output stage for high grade sound accuracyCompact size – all models only 1 RU for reduced rack cost and spaceLight weight – for easier racking and shipping: 7 kg (15.4 lbs)Standard Phoenix connectors: analog audio outputs, aux supply, alarms and GPIORemotely switchable double input (main and aux) per channelSettingsBuilt-in defeatable clip limiters for each channelDigital gain-attenuator controlDefeatable gate selection for each channelUser selectable gain/sensitivityUser selectable maximum output power for each channelUser selectable maximum mains current drawLockable set-up by user selectable access key codeBuilt in remote control via the RS-485 interface provides full diagnostic, operational setting and system monitoringDigital Signal ProcessingTI C6000 DSP platformAD/DA converter: dual 24bit @ 48 kHz Tandem® architectureInput/output independent equalizers per channel providing PEQ, raised cosine, shelving IIR filters as well as custom output FIR filtersDelay up to 100 ms for time alignmentActive DampingControl™ for cable compensationPeak, RMS voltage, RMS current, TruePower™ limitersRemote Control and MonitoringVia Software:Control and diagnostics monitoring via ArmoniaPlusDedicated WebAppVia Hardware:Attenuation (from 0dB to 26dB)High-pass filters (35Hz, 70Hz)Lo-Z/Hi-Z/70V/100V output selectionAdjustable gain (from 26dB to 35 dB)SpecificationsGENERALOutput power per ChannelOutput power per Channel1500 W @ 2 Ω1200 W @ 4 Ω1200 W @ 8 ΩBridge mode3000 W @ 4 Ω2400 W @ 8 ΩMax output voltage / currentMax unclipped voltage @8 Ω139 VpeakCurrent45 ApeakAC MAIN POWERPower supplyUniversal, regulated switch mode with PFC (Power Factor Correction)Nominal power requirement100-240 V ±10%, 50-60 HzOperating voltage90 V – 264 VPower consumption/current drawIdle115 V: 31.3 W – 0.47 A230 V: 31.6 W – 0.27 A1/8 of max output power @ 4 Ω115 V: 823 W – 7.7 A230 V: 840 W – 4.3 ATHERMALOperating temperature range0° – 45° C – 32° – 113° FThermal dissipation*Idle115 V: 107 BTU/h230 V: 108 BTU/h1/8 of max output power @ 4 Ω115 V: 760 BTU/h230 V: 818 BTU/h
