Neue Webseite unter Audition6Benchmark Media AHB2 Referenz Stereo EndverstärkerModell Herbst 2023 UVP: Euro 4400,-- Zum Verkauf kommt ein nagelneuer Benchmark Media AHB2 Referenz Stereo Endverstärker des amerikanischen Spezialisten.Wird nach Kauf beim deutschen Vertrieb geordert, will be ordered after purchase.Evtl. etwas Lieferzeit einplanen. Maybe some waiting time.Einmalige Chance!Näheres finden Sie auf der Webseite des Herstellers!Technik Benchmark AHB2Benchmark Media AHB2Die Reinheit des Klangs übertrifft Class A VerstärkerDer AHB2 ist ein Endverstärker. Sein Klang übertrifft die Qualität von Class A Verstärkern.Er ist ein echter Benchmark: Kein Verstärker hat geringeres Rauschen oder niedrigere Verzerrungen!Ein kleines, passiv gekühltes Gehäuse liefert saubere 480 Watt an 6 Ohm im Bridge-Mono-Betrieb!Mit zusätzlichen Reserven, um auch schwierige Lautsprecher Lasten anzutreiben. Ungleich zu leistungshungrigen Class A-Verstärkern erreicht er eine Leistungseffizienz vergleichbar zu Class D Schaltverstärkern.Schwierige Lautsprecherlasten werden locker bedientViele Lautsprecher haben ein Impedanzminimum weit unter der nominalen Impedanz.DerAHB2 treibt locker schwierige Phasenverläufe niedrige Impedanzen.Stereo Lasten mit bis zu 1,4 Ohms können bis zur Leistungsgrenze sauber betrieben werden.Die meisten Verstärker erzeugen höhere Verzerrungen , wenn die Impedanz der angeschlossenen Lautsprecher sinkt. Im Gegensatz dazu bleibt der AHB2 auf seinem niedrigen Verzerrungsniveau.auch bei schwierigen Lasten.Hoher DämpfungsfaktorDer AHB2 hat einen hohen Dämpfungsfaktor für einen kontrollierte Basswiedergabe.Der hohe Dämpfungsfaktor sorgt für einen absolut linearen Frequenzgang selbst bei starken Impedanz-Schwankungen.Hoher AusgangsstromDer AHB2 kann bis zu 29 A Spitzenstrom liefern, gleichzeiig für beide Kanäle.Verzerrungswerte unter HörbarkeitsschwelleDer AHB2 wird unter keinen Umständen hörbare Verzerrzngen erzeugen. Technische Daten Benchmark AHB2Continuous Average Output Power< 0.0003 % THD+N at full rated power, 20 Hz to 20 kHz100 Watts per channel into 8 Ohms, both channels driven130 Watts per channel into 6 Ohms, both channels driven190 Watts per channel into 4 Ohms, both channels driven240 Watts per channel into 3 Ohms, both channels driven200 Watts into 16 Ohms, bridged mono380 Watts into 8 Ohms, bridged mono480 Watts into 6 Ohms, bridged monoAll speakers have variations in input impedance. Select loads based on nominal impedances not minimum impedances. The AHB2 is stable into all loads. The AHB2 is conservatively rated at an output level where THD+N is < 0.0003 % instead of the more typical 1% THD+N. Power at 1% THD will be higher.Output Voltage Into Various Load Impedances< 0.0003 % THD+N at the following output voltages and load impedances, 20 Hz to 20 kHz29.03 dBV, 31.25 dBu, 28.28 Vrms into 8 Ohms, both channels driven28.92 dBV, 31.14 dBu, 27.93 Vrms into 6 Ohms, both channels driven28.81 dBV, 31.03 dBu, 27.57 Vrms into 4 Ohms, both channels driven28.57 dBV, 30.79 dBu, 26.83 Vrms into 3 Ohms, both channels driven27.14 dBV, 29.36 dBu, 22.76 Vrms into 2 Ohms, both channels driven35.05 dBV, 37.27 dBu, 56.57 Vrms into 16 Ohms, bridged mono34.83 dBV, 37.05 dBu, 55.14 Vrms into 8 Ohms, bridged mono34.59 dBV, 36.81 dBu, 53.67 Vrms into 6 Ohms, bridged mono33.16 dBV, 35.38 dBu, 45.52 Vrms into 4 Ohms, bridged monoUse dBV to calculate the peak SPL from your speaker/amplifier combination. Use the following formula: Amplifier output voltage in dBV + speaker sensitivity at 2.83V - 9 dB. Example: (29.03 dBV at 8 Ohms) + (90 dB SPL @ 2.83V 1m) - 9 dB = 110 dB SPL at 1 meterSNR & Dynamic RangeRated output relative to output noise, inputs shorted132 dB A-weighted, Stereo Mode135 dB A-weighted, Mono Mode130 dB Unweighted, 20 Hz to 20 kHz, Stereo Mode133 dB Unweighted, 20 Hz to 20 kHz, Mono ModeNoise VoltageOutput noise voltage, A-weighted, inputs shorted-103 dBV, -101 dBu, 7.1 uVrms, Stereo Mode-100 dBV, -98 dBu, 9.8 uVrms, Mono ModeUse dBV to calculate the SPL of the noise produced by your speaker/amplifier combination. Use the following formula: Amplifier output noise voltage in dBV + speaker sensitivity at 2.83V - 9 dB. Example: Mono mode driving very high efficiency speakers: (-100 dBV) + (104 dB SPL @ 2.83V 1m) - 9 dB = -5 dB SPL at 1 meter. This means that the system noise will be 5 dB below the threshold of hearing when driving speakers with a very high 104 dB efficiency.Noise Relative to 2.83 VrmsOutput noise relative to 2.83 Vrms, A-weighted, inputs shorted-112 dB, Stereo Mode-109 dB, Mono ModeTHD+N1 kHz, 80 kHz LPF, at full rated output into any rated load< -118 dB (< 0.00013%), Stereo Mode< -118 dB (< 0.00013%), Mono ModeTHD1 kHz, 20 kHz LPF, at full rated output into any rated load< -119 dB (< 0.00011%), Stereo Mode< -120 dB (< 0.00010%), Mono ModeCrosstalkBetter than -115 dB at 1 kHzBetter than -92 dB at 20 kHzFrequency ResponseBetter than 0.1 Hz to 200 kHz, +0/-3 dB-0.01 dB at 20 Hz, -0.17 dB at 20 kHz, 8-Ohm Load-0.23 dB at 20 Hz, -0.32 dB at 20 kHz, 4-Ohm LoadDamping Factor350 at 20 Hz, 8-Ohms254 at 1 kHz, 8-Ohms34 at 20 kHz, 8-Ohms7 at 200 kHz, 8-Ohms Maximum Audio Output Current29 A peak, per channel, both channels drivenInput SensitivityLow-Gain = 22 dBu (9.8 Vrms), Gain = 9.2 dBMid-Gain = 14.2 dBu (4 Vrms), Gain = 17.0 dBHigh-Gain = 8.2 dBu (2 Vrms), Gain = 23 dBUse Mid-Gain or High-Gain settings for unbalanced inputsUnbalanced inputs require RCA to XLRM adapter cables Input Impedance50 k Ohms, normal mode1 M Ohm, common modeInput CMRR80 dB at 20 Hz, typical80 dB at 1 kHz, typical65 dB at 20 kHz, typicalTrigger I/O12 VDC 200 mA current-limited output to trigger turn-on of remote devicesDC input for slaving to remote devicesInput responds to 3.3 V logic and higher, VIL = 1.26 V, VIH = 2.7 VAbsolute maximum input voltage = 30 VDCAbsolute minimum input voltage = -0.3 VDCInput Impedance = 20 k OhmsProtection CircuitsFully Electronic, No RelaysMute SequencingDistortion DetectionShort Circuit DetectionOver Current DetectionOver Temperature DetectionSOA Detection (Output device safe operating area)DimensionsNon-rack-mount version:11.04 W x 3.88 H x 9.34 D - Including feet and binding posts11.04 W x 3.47 H x 8.33 D - Excluding feet and connectorsFaceplate height is 2RURack-mount version:19.00 W x 3.88 H x 10.62 D - Including binding posts, handles and removable feet19.00 W x 3.47 H x 8.33 D - Excluding feet and connectors9.09 rack depth, including binding posts, excluding cables11 rack depth, including cablesFaceplate height is 2RUWeight12.5 lbs., 16 lbs. shipping - Non-rack-mount version13.5 lbs., 17 lbs. shipping - Rack-mount versionAC InputAuto-ranging AC Input100 to 120 VAC +/- 10%, 8 Amps, 50 - 60 Hz220 to 240 VAC +/- 10%, 8 Amps, 50 - 60 HzIdle Power Consumption = 20 WStandby Power Consumption < 0.5 W
