Housed in a 4U rack chassis measuring 17.25 by 5.25 by 20 inches and weighing 55 lbs net, it delivers 180 watts RMS per channel into 8 ohms and 255 watts RMS per channel into 4 ohms with all five channels operating at once.\u003c\/p\u003e\u003cp\u003eEach channel draws up to 45 amps peak, and the amplifier holds total harmonic distortion to 0.05 percent RMS continuous across the full 20 Hz to 20 kHz audio band. Frequency response spans 5 Hz to 100 kHz within 3 dB. Signal-to-noise ratio exceeds 112 dB IHF A-weighted. Balanced XLR and unbalanced inputs are both accommodated, with a common 29 dB gain stage. Standby consumption is 1 watt with a maximum draw of 1,500 watts, and a 9-12 Vdc trigger input is provided for system control.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e180W RMS x 5 into 8 ohms, 255W RMS x 5 into 4 ohms, all channels driven\u003c\/li\u003e\n\u003cli\u003e45 amps peak current per channel\u003c\/li\u003e\n\u003cli\u003eTHD 0.05% RMS continuous, 20 Hz - 20 kHz\u003c\/li\u003e\n\u003cli\u003eSNR greater than 112 dB, IHF A-weighted\u003c\/li\u003e\n\u003cli\u003eBalanced XLR and unbalanced inputs, 29 dB gain\u003c\/li\u003e\n\u003cli\u003e1W standby, 1,500W maximum power draw\u003c\/li\u003e\n\u003cli\u003e4U chassis, net weight 55 lbs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRack Spacing:\u003c\/strong\u003e 4U\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChannels:\u003c\/strong\u003e 5-Channel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWatts Per Channel:\u003c\/strong\u003e 201-300W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Output @ 8 ohm:\u003c\/strong\u003e 180W RMS x 5, 20 Hz - 20 kHz, 8 Ω, all channels driven\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Output @ 4 ohm:\u003c\/strong\u003e 255W RMS x 5, 20 Hz - 20 kHz, 4 Ω, all channels driven\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Output Bridged @ 8 ohm:\u003c\/strong\u003e n\/a\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Consumption:\u003c\/strong\u003e Standby: 1W Idle: 125W Maximum: 1500W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Rating:\u003c\/strong\u003e 45 amps peak, per channel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTotal Harmonic Distortion (THD):\u003c\/strong\u003e 0.05% THD, RMS continuous power, full audio band (20 Hz - 20 kHz)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower RMS:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency Response:\u003c\/strong\u003e 5 Hz - 100 kHz, +0\/-3 dB 20 Hz - 20 kHz, +0\/-0.3 dB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAudio Crosstalk:\u003c\/strong\u003e \u0026gt; 78 dB at 1 kHz \u0026gt; 63 dB at 20 kHz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImpedance Input:\u003c\/strong\u003e Unbalanced: 47 kΩ Balanced: 94 kΩ, 47 kΩ per leg\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAudio Gain:\u003c\/strong\u003e 29 dB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSensitivity Input:\u003c\/strong\u003e Unbalanced: 1 V Balanced: 1 V per leg\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSignal to Noise Ratio:\u003c\/strong\u003e \u0026gt; 112 dB, input shorted, IHF A-weighted \u0026gt; 102 dB, input shorted, unweigh\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmplifier Requirements:\u003c\/strong\u003e Audio Trigger: 2 mV - 10 mV\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExternal Trigger Voltage:\u003c\/strong\u003e +9 Vdc to +12 Vdc, 2 mA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnectors:\u003c\/strong\u003e XLR Pin Identification 1 = Ground (Shield) 2 = Positive 3 = Negative (Return)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions (W x H x D):\u003c\/strong\u003e 17.25\" x 5.25\" x 20\" (437 x 133 x 508mm) (without feet)17.25\" x 5.88\" x 20\" (437 x 149 x 508mm) (with feet) Depth with cables: 21.25\" (540mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e Net Weight: 55 lbs (25 kg)Shipping Weight: 69 lbs (31.3 kg)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Parasound","offers":[{"title":"Default Title","offer_id":46346885365957,"sku":"PARA-A52P","price":4000.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0630\/3085\/3829\/files\/A52_2B_20high_20angle_20black-f.jpg?v=1781125661","url":"https:\/\/avlgear.com\/products\/parasound-halo-series-a-52-power-amplifier-255w-x-5-channels","provider":"AVLGEAR","version":"1.0","type":"link"}
