RAGNAROK 諸神的黃昏
產品介紹

Ragnarok是世上第一個可從超靈敏的入耳式耳機到喇叭都可以連結的綜合擴大機。在100WPC RMS下為4歐姆,有三個可選擇的gains,一個繼電器切換可加強或衰減音量控制程度。截取自MY-HIEND

Status: Built and qualified to order after public beta is complete. Orders placed after the public beta will ship in 2-3 working weeks. Your card will not be charged until the order ships.

Ragnarok is the first truly universal amplifier, fully capable of powering everything from IEMs to loudspeakers. With up to 100 watts per channel into 4 ohms, 3 selectable gains, a sophisticated relay-switched stepped attenuator volume control, complete microprocessor management of all operational points, including bias and DC offset, and Schiit’s Crossfet™ circlotron-style output topology, Ragnarok completely befits its name—in Norse legend, Ragnarok was the “end of the world.”

From IEMs to Loudspeakers

Go ahead. Plug in your sensitive headphones and set Ragnarok’s gain to 1. You’ll enjoy a silent background, and the fine control that a 64-step attenuator can provide. Or run it with the most power-hungry orthos you know. With gain set at 20, and 15W RMS into 32 ohms, you’re ready for an amazing performance. Speakers? No problem. With 60W per channel into 8 ohms, Ragnarok delivers amazing performance with most popular speakers.

 

A Complete Integrated Amp

Ragnarok includes 5 relay-switched inputs—two balanced and three single-ended, as well as balanced and single-ended preamp outputs for use as a preamp. For outputs, both balanced and single-ended outputs are provided for headphones, and balanced speaker terminal outputs for loudspeakers.

 

Nothing In the Signal Path Except Signal

Ragnarok uses a microprocessor to oversee every aspect of its operation—from quiescent bias, to DC offset, to complete fault protection. It’s also designed so that any major problem mutes all the outputs and reverts the amp to its low-gain, zero volume mode. This means we can dispense with coupling caps and DC servos entirely, for a gain stage that has nothing in the signal path—except for your music.

 

Made in USA 

By “made in USA,” we mean made in USA. Ragnarok is built to order in Valencia, CA, by our most experienced assemblers, subjected to a rigorous series of both instrumented and listening tests, and burnt in for 100+ hours before being re-tested and shipped. As with all of our products, the vast majority of the total production cost of Ragnarok—chassis, boards, transformers, assembly, etc—goes to US companies manufacturing in the US. Our board house is 20 minutes away from our office in Newhall. Our chassis guys are just over the hill in the Valley.
