Thông tin chi tiết
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 is an “intelligent” amplifier, using 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.
Designed and Assembled in USA
By “designed and assembled in USA” this is what we mean: the vast majority of the total production cost of Ragnarok—chassis, boards, transformers, assembly, etc—goes to US companies manufacturing in the US. Our chassis are made minutes from our facility. Our PCBs are done just over the hill from us, or done in NorCal. Our transformers are also made in California. You get the picture.
