2 RCA Single-Ended
Inputs. If you have a
single-ended source,
don’t despair. Mjolnir’s
inherently balanced
amplification stage
converts every input to
balanced output. But be
sure to hit the switch
(see #3.)
1 XLR Balanced
Inputs. Connect your
balanced source here for
best sound. Mjolnir does
not convert balanced to
single-ended and back
again.

3 Single-Ended
Grounding Switch.
Your single-ended inputs
sometimes appreciate
a ground reference for
lowest noise. Some-
times they don’t. Down
grounds the RCAs, up
lets them float.
Important: connect
only one pair of inputs
at a time (RCA or XLR).
The inputs are shared,
so you’re shorting them
together if you connect
both RCA and XLR.
4 XLR Balanced
Preamp Outputs.
Mjolnir can be used as
a high-quality balanced
preamp. Outputs are
muted for 20 seconds
when the amp turns on,
and whenever the amp
is in protection mode.

5 On-Off Switch.
Up is on. Down is off.
Pretty simple here. We
recommend turning off
Mjolnir when you’re not
wielding...er,using...it.
6 AC Input. Plug the
power cord in here.
Plug the other end into a
wall outlet of the correct
voltage. Trying to run a
115V unit on 230V will
result in a blown fuse,
no music, and a void
warranty.
7 Disclaimer. No,
seriously. Don’t take
this apart. Don’t stick
paperclips through the
holes on the top or side.
There are dangerous
voltages inside, and we
don’t want you to die.
