Using their “Nexus” differential gain stage, Ragnarok 2 can drive both speakers (60w @ 8Ω, 100w @ 4Ω) and headphones (upto 24w into 32Ω … enough power for even the most demanding planar cans), and has three selectable levels of gain. This gain stage allows direct operation in both balanced and single-ended operation within the stage (including conversion between them), and doesn’t require discrete conversion outside the gain stage itself.
The modular nature of the unit means that in addition to it’s standard 2x balanced (XLR) and 1x single-ended (RCA) inputs, its two internal card slots can be used to add additional single-ended inputs, a multi-bit DAC or a phono-stage, for 5 total inputs.
Standard outputs include single-ended and balanced pre-outs, speaker binding posts and, of course, both 4-pin XLR and 1/4" TRS headphone outputs.
This is the thread to discuss it …
