Can be bridged for 500 W mono\u003c\/h3\u003e\n\u003cp\u003eWith circuitry designed by the legendary John Curl, the Parasound Halo A23+ is a hugely powerful high-bias class-A with AB operation that delivers 45 A peak current per channel. It will drive even speakers whose loads dip below 2 Ohm. It has balanced inputs with discrete circuits, and the direct coupled signal path means no capacitors or inductors get in the way of great sound.\u003c\/p\u003e\n\u003ch4\u003eThe Upscale View\u003c\/h4\u003e\n\u003cp\u003eParasound is one of the industry's low-key, high-return brands. It's not always the first name on a customer's lips, yet is a hugely respected and loved brand by people who work in high-end audio. This isn't just because of the legendary John Curl who is behind most of its top-flight designs, but also because Parasound uses such expensive and solid engineering, yet is able to price its products so reasonably. Parasound is the brand of choice for someone who really knows good sound, but doesn't have the budget for audio jewellery.\u003c\/p\u003e\n\u003ch4\u003eThe Best Parts\u003c\/h4\u003e\n\u003cp\u003eThe JFET input stage is connected to a MOSFET driver stage, and the amp uses 12 beta-matched 15 ampere, 60 MHz bipolar output transistors. The 27 lb. amp uses a 1.1 kVA shielded toroidal transformer with independent windings for each channel. There are independent power supplies for the input, driver, and output stages. The output stage uses 54,400 µF filter capacitors. Harris hyper-fast soft-recovery bridge diode rectifiers continue the theme of expensive, overspecified design that results in a sound with huge power and headroom. Full power is rated all the way down to 5 Hz for unrestricted low-end bass.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eDC Servo and relay protection circuits\u003c\/li\u003e\n\u003cli\u003eAC turn-on inrush surge protection with relay bypass\u003c\/li\u003e\n\u003cli\u003eAutomatic turn-on by 12 V trigger or audio sensing\u003c\/li\u003e\n\u003cli\u003e2 rack space chassis with rear carry handles\u003c\/li\u003e\n\u003cli\u003eRack mount hardware included\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003ePower Output (8, 4, 1 Ohm):\u003c\/strong\u003e 160 W, 240 W, 500 W\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInputs:\u003c\/strong\u003e Stereo RCA, stereo XLR, DC trigger\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInput Impedance (Bal., SE):\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan\u003e66 kΩ, \u003c\/span\u003e\u003cspan\u003e33 kΩ\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGain:\u003c\/strong\u003e 29 dB\u003c\/p\u003e\n\u003cp\u003e\u003cstrong data-start=\"107\" data-end=\"128\"\u003eDimensions (WHD):\u003c\/strong\u003e 17.25\" x 4.13\" x 15.25\" (438 x 105 x 387 mm)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong data-start=\"176\" data-end=\"187\" data-is-only-node=\"\"\u003eWeight:\u003c\/strong\u003e 27 lb.
