- Complete Integrated Amplifer
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.
Drives IEMs & Loudspeakers
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 orthodynamic headphones you're aware of. With gain set at 20, and 15W RMS into 32 ohms, you’re ready for an amazing performance. Also, with 60W per channel into 8 ohms, Ragnarok delivers amazing performance with most popular speakers.
Only Signal in the Signal Path
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.
What Are Intelligent Microprocessors?
Lots of amps use microprocessors to oversee their fault protection.
But Ragnarok goes much farther than that. It uses a 16-bit PIC micro controller and 12-bit DACs to monitor and regulate all operational points of the amplifier, including quiescent current, DC offset, and overcurrent protection. It samples key operational points about 30 times a second, and provides continuously updated control inputs to the gain stage about 3 times per second (or faster, in the case of a fault.) The benefits of this are as follows:
1. Ragnarok's operating points won't change over time. Once it's on, and the control system has settled to its thermal operating point, Ragnarok's performance is consistent and predictable.
2. Schiit can throw out the DC servo entirely. DC servos are a technique that many amps use to eliminate DC offset on the output without coupling capacitors.Ragnarok’s signal path is DC-coupled from input to output, with no DC servo—and no worries that the DC operating point will drift over time.
3. If there is ever any fault (shorted speaker cables, AC power loss, etc), Ragnarok is engineered to provide a hard shutdown to protect speakers and headphones—disconnecting all outputs, reducing the input volume to minimum, and defaulting to the lowest gain mode.
Made in USA
The vast majority of the total production cost of the Ragnarok—chassis, boards, assembly, etc—goes to American companies manufacturing in the US. Making Schiit's Ragnarok truly 'Made in USA'.
