A mono switch can improve the sound of mono LPs. Variable MC impedance can be adjusted between 50 and 550 Ohm.\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.\u003cbr\u003e\u003c\/p\u003e\n\u003ch4\u003eAnother John Curl Classic\u003c\/h4\u003e\n\u003cp\u003eDesigned by John Curl—the creator of the legendary Vendetta Research phono preamp—this phonostage is built around a true dual-mono topology. Each audio channel is physically separated and enclosed in its own extruded aluminum housing, with independent high-speed soft-recovery rectifiers, filter capacitors, and voltage regulators for left and right channels. Triple shielding and low-carbon mild-steel partitions isolate the power supplies and AC wiring from the audio circuits, contributing to RIAA accuracy specified within 0.2 dB.\u003c\/p\u003e\n\u003cp\u003eSignal integrity is reinforced through deliberate component and connector choices. The audio path uses Vishay-Dale resistors. Inputs and unbalanced outputs are handled by Vampire 24k gold-plated RCA jacks, while balanced outputs use premium Neutrik XLR connectors. Loading options cover MM at 47 kΩ, MC at 47 kΩ, or variable MC loading adjustable from 50–550 Ω. A mono switch is provided to improve playback of mono and older LPs.\u003c\/p\u003e\n\u003cp\u003eAttention is also paid to power and system integration. A built-in AC line noise conditioning circuit helps prevent mains interference from entering the audio stages, and an AC polarity reverse switch can reduce hum in certain system configurations. A non-magnetic aluminum rear panel is used to avoid magnetic interaction near signal connections. Turn-on behavior can be set to manual or automatic operation via a 12 V trigger input. Power is supplied through a premium detachable heavy-gauge IEC AC cord, and the 2U chassis is rack-mountable using the optional HRA2 kit.\u003c\/p\u003e\n\u003ch4\u003eThe Finest Components\u003c\/h4\u003e\n\u003cp\u003eOnly the finest components are used, with Vishay-Dale resistors in the audio path, Vampire 24k gold-plated RCA jacks, and Neutrik XLR connectors.\u003c\/p\u003e\n\u003cp\u003eA triple shield separates power supply and audio circuits, and the design is fully dual mono. The rear panel is also aluminum. The power supply uses high-speed soft recovery bridge rectifiers and common-mode inductors.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eInputs:\u003c\/strong\u003e Stereo RCA, 12 V trigger\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOutputs:\u003c\/strong\u003e Stereo RCA, stereo XLR\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInput Impedance\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eMM or MI:\u003c\/strong\u003e 47k Ω\u003cbr\u003e\u003cstrong\u003eMC:\u003c\/strong\u003e 50- 550 Ω\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOutput Impedance\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eUnbalanced:\u003c\/strong\u003e \u0026lt; 100 Ω\u003cbr\u003e\u003cstrong\u003eBalanced:\u003c\/strong\u003e \u0026lt; 100 Ω per leg\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInput Capacitance:\u003c\/strong\u003e 150 pF\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGain (MM, MC):\u003c\/strong\u003e 48 dB, 64 dB\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDimensions (WHD):\u003c\/strong\u003e 17-1\/4\" x 4-1\/8\" x 13-3\/4\"\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWeight:\u003c\/strong\u003e 19 lb.\u003c\/p\u003e","brand":"Parasound","offers":[{"title":"Black","offer_id":42552014110904,"sku":"JC3+ BLK","price":3350.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1564\/1247\/files\/jc3__black_front.jpg?v=1760742531","url":"https:\/\/upscaleaudio.pro\/products\/parasound-halo-jc-3-phono-preamplifier","provider":"Upscale Audio","version":"1.0","type":"link"}
