Occupying 3U of rack space in a chassis measuring 17.25 by 3.5 by 15.25 inches and weighing 27 lbs net, it delivers 160 watts per channel into 8 ohms and 240 watts per channel into 4 ohms with both channels driven, and 500 watts in bridged mono configuration into 8 ohms.\u003c\/p\u003e\u003cp\u003ePeak current delivery is 45 amps per channel. Total harmonic distortion is rated at 0.06 percent. Signal-to-noise ratio exceeds 112 dB IHF A-weighted with the input shorted. Channel crosstalk is greater than 85 dB at 1 kHz and greater than 70 dB at 20 kHz. Both balanced XLR and unbalanced inputs are provided with a shared 29 dB gain stage. Power consumption ranges from under 1 watt in standby to a maximum of 800 watts, and the unit accepts 110-125 or 220-250 VAC selectable on the rear panel.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e160W x 2 into 8 ohms, 240W x 2 into 4 ohms, both channels driven\u003c\/li\u003e\n\u003cli\u003eBridged mono: 500W into 8 ohms\u003c\/li\u003e\n\u003cli\u003e45 amps peak current per channel\u003c\/li\u003e\n\u003cli\u003eTHD 0.06% at rated output\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\u003eSelectable 110-125V \/ 220-250V operation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRack Spacing:\u003c\/strong\u003e 3U\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChannels:\u003c\/strong\u003e 2-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 160W x 2, 8 Ω both channels driven\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Output @ 4 ohm:\u003c\/strong\u003e 240W x 2, 4 Ω both channels driven\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Output Bridged @ 8 ohm:\u003c\/strong\u003e 500Wx 1, 8 Ω Bridged; 4 Ω operation is not recommended\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Consumption:\u003c\/strong\u003e Standby: \u0026lt;1W Idle (no music playing): 75W Typical Listening levels: 125W Maximum: 800W 110-125 VAC 60 Hz or 220-250 VAC 50 Hz AC mains voltage is set on rear panel\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 0.06% THD\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 \u0026gt; 85 dB at 1 kHz \u0026gt; 70 dB at 20 kHz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAudio Crosstalk:\u003c\/strong\u003e \u0026gt; 85 dB at 1 kHz \u0026gt; 70 dB at 20 kHz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImpedance Input:\u003c\/strong\u003e for 28.28 V Output into 8 Ω Unbalanced: 1 V Balanced: 1 V 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 for 28.28 V Output into 8 Ω 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; 107 dB, input shorted, unweighted\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, 5 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 3.5\" x 15.25\" (437 x 89 x 388mm) (without feet) 17.25\" x 4.13\" x 20\" (448 x 105 x 508mm) (with feet) Depth with cables: 17\" (432 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e Net Weight: 27 lbs (12.2 kg) Shipping Weight: 34 lbs (14.4 kg)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Parasound","offers":[{"title":"Default Title","offer_id":46346891329733,"sku":"PARA-A23P-BL","price":2500.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0630\/3085\/3829\/files\/A23_2B_20high_20angle_20black.jpg?v=1781125774","url":"https:\/\/avlgear.com\/products\/parasound-halo-series-a-23-stereo-power-amplifier-240w-x-2-channels-black","provider":"AVLGEAR","version":"1.0","type":"link"}
