Lab Gruppen E54 500W 4-Channel Power Amplifier – Flexible Output, High-Performance Audio

Description System installers in search of a compact, flexible amplifier with Hi-Z and Lo-Z output capabilities should check out the Lab.Gruppen E 5:4, a 1 RU, four-channel 500W amplifier for mixed A/V installation applications. The E 5:4 utilizes IntelliDrive Energy Efficient Amplifier (IDEEA) technology to produce high power levels with very low distortion while drawing minimal mains current.E-Series amplifiers also utilizes Lab.Gruppen’s proprietary Rail Sensing Limiter (RSL) technology, which greatly reduces signal clipping to ensure high-quality audio output all the time. The amplifier is user-configurable for Hi-Z (70/100V) or Lo-Z. The RSL circuit senses rail voltage and optimizes each channel output for instantaneous load conditions. This allows for asymmetrical channel loading for optimized performance and efficiency. Total available output power can be allocated among the channels as required by the application. This makes it possible, for example, to drive a small sub on one channel and several 70/100V ceiling loudspeakers on the other channels. Features of Lab.Gruppen E 5:4Two-Channel Amplifier: 4 x 125WIntelliDrive: 70/100V or 4, 8, 16 OhmsEnergy-Efficient Class-D AmplifierAsymmetric Channel LoadingComprehensive Circuit ProtectionRail Sense Limiter (RSL)Includes Screw Terminal I/O BlocksIncludes Power CordApplications of Lab.Gruppen E 5:4Commercial Audio InstallationsBackground music (BGM) systemsForeground music in restaurants, cafés, and retail storesDistributed audio in malls and shopping centersOffice buildings and corporate AV systemsHouses of WorshipDistributed sound zones (e.g., lobby, sanctuary, classrooms)Low/medium-power speaker systemsAssisted listening system amplificationConference Rooms & Meeting SpacesCorporate boardroomsMedium-sized conference roomsDigital signal processor (DSP)–controlled installationsCeiling speaker arrays (4–8 speakers per channel, depending on impedance configuration)Education FacilitiesClassrooms and lecture hallsMulti-zone campus audio systemsAuditoriums with distributed speaker linesHospitality & Leisure VenuesHotels and resortsGyms and fitness centersSpas and wellness centersBars, lounges, and entertainment venuesMulti-Zone Audio SystemsThe E 5:4’s Flexible Output Mode allows channels to be combined or configured independently, making it ideal for:2-zone / 3-zone / 4-zone setupsDistributed speaker linesPaging music systemsSmall to Medium Performance SpacesCommunity hallsRehearsal studiosSmall theaters (for fills and auxiliary zones)Fixed Install Sound ReinforcementMuseums and exhibit centersGovernment buildingsPublic address (PA) systemsAirports and transit terminals (non-critical paging)Specifications of Lab.Gruppen E 5:4Form Factor/TypeRackmountNumber of Amplifier Channels4Load Impedance/Voltage Support4 / 8 / 16 Ohms 100 / 70 VPower Rating per Channel4x 125 W at 8/4 Ohms 4x 63 W at 16 Ohms 4x 125 W at 100/70 VAmplifier ClassClass-DPerformanceProtectionsRMS, Reactive/Mismatched Load, Short Circuit, Signal Limiter, Thermal, UndervoltageFrequency Response2 Hz to 40 kHzSNR/Noise> 112 dBA SNRTHD/Distortion≤ 0.1% THD (20 Hz to 20 kHz, at 1 W) ≤ 0.05% THD (1 kHz, Below Rated Power)Crosstalk> 70 dBSignal ProcessingDSPNoAudio DelayNoEQ & FiltersHigh-Pass FilterDynamicsLimiterConnectivityAnalog Audio I/O4x Block 3-Pin Balanced Line Input 4x Block 2-Pin SpeakerDigital Audio I/ONoNetwork I/ONoOther I/O2x Block 2-Pin GPIOUSB I/ONoPhantom PowerNoWirelessNoPowerInput Power100 to 240 VAC, 60 / 50 HzAC Power Connector1x IEC 15 A / NEMA 5-15Power Consumption1 W (Standby)PhysicalDisplaySingle-LED Indicators OnlyRackmount Size1 UCoolingFan (Variable Speed)CertificationsANSIS1.4 Type 2, CCC, CE, CSA, ENERGY STAR, ETL, PSE, RoHS, UL, WEEEDimensions19 x 15 x 1.8″ / 482.6 x 381 x 45.7 mmWeight13.2 lb / 6 kgPackaging Info Package Weight20.21 lbBox Dimensions (LxWxH)23.2 x 21.2 x 5.7″
