It delivers 120 W per channel into 8 ohms or 150 W per channel into 4 ohms using closed-loop digital switching amplifiers.\u003c\/p\u003e\n\n\u003cp\u003eIts compact 2U chassis can be rack mounted using the included removable mounting ears or used as a conventional standalone component. The highly efficient class D design requires no cooling fans during normal operation, making it well suited to multizone installations and equipment racks.\u003c\/p\u003e\n\n\u003cp\u003eEach channel has an individual unbalanced analog input, volume control, and 2-pole Phoenix-style push-in speaker terminal. Two digital audio inputs accept either coaxial or optical signals and can be bussed across channels, while channel-summing circuitry simplifies mono signal distribution.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\n\u003cul\u003e\n\u003cli\u003e120 W per channel into 8 ohms\u003c\/li\u003e\n\u003cli\u003e150 W per channel into 4 ohms\u003c\/li\u003e\n\u003cli\u003eClosed-loop digital switching amplifier design\u003c\/li\u003e\n\u003cli\u003eIndividual unbalanced analog inputs\u003c\/li\u003e\n\u003cli\u003eCoaxial and optical digital audio inputs\u003c\/li\u003e\n\u003cli\u003eBUS inputs and outputs\u003c\/li\u003e\n\u003cli\u003eChannel-summing circuitry\u003c\/li\u003e\n\u003cli\u003eIndividual channel volume controls\u003c\/li\u003e\n\u003cli\u003ePower Guard® signal overload protection\u003c\/li\u003e\n\u003cli\u003eSentry Monitor™ short-circuit protection\u003c\/li\u003e\n\u003cli\u003ePower Control 12 V triggering\u003c\/li\u003e\n\u003cli\u003eAutomatic on\/off signal sensing\u003c\/li\u003e\n\u003cli\u003eFanless operation\u003c\/li\u003e\n\u003cli\u003e2U rack mounting with removable ears\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\n\u003cp\u003e\u003cb\u003ePower Output:\u003c\/b\u003e 120 W per channel into 8 ohms; 150 W per channel into 4 ohms\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eNumber of Channels:\u003c\/b\u003e 8\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eTotal Harmonic Distortion:\u003c\/b\u003e 0.05%\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eSignal-to-Noise Ratio:\u003c\/b\u003e 95 dB below rated output\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eDynamic Headroom:\u003c\/b\u003e 2.1 dB into 8 ohms; 3.3 dB into 4 ohms\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eDamping Factor:\u003c\/b\u003e \u0026gt;65 into 8 ohms; \u0026gt;32 into 4 ohms\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eRated Power Band:\u003c\/b\u003e 20 Hz–20 kHz\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eFrequency Response:\u003c\/b\u003e +0, -0.5 dB from 20 Hz–20 kHz\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eCircuit Configuration:\u003c\/b\u003e Closed-loop digital switching\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eOutput Type:\u003c\/b\u003e Direct coupled\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eSpeaker Connections:\u003c\/b\u003e 2-pole Phoenix-style push-in terminals\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eDimensions (H × W × D):\u003c\/b\u003e 4-5\/16\" × 17-1\/2\" × 21\" (110 × 445 × 533 mm)\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eWeight:\u003c\/b\u003e 22 lb.
