he Micstasy is an 8-channel hi-end mic/line/instrument preamp and AD converter combining typical
RME features with a number of previously unseen features. Along with SteadyClock, the Micstasy not
only offers low latency AD conversion of the highest quality, but is also fully remote-controllable via
MIDI and also MIDI over MADI.
Universal input device. The Micstasy’s innovative concept allows for amplification and digitization of all
analog signal sources, including high level stage signals, typical studio signals, lower level and high-impedance
instruments, or dynamic, condenser or ribbon microphones. The impressive 85 dB gain range, digitally
controlled in steps of 0.5 dB, allows connection of all conventional analog studio signals within a range of -56

he OctaMic II provides 8-Channel 192 kHz / 24 bit AD conversion with eight hi-class microphone and line preamplification channels, featuring a combination of sophisticated components and approved RME technology.
Lowest distortion, excellent signal to noise ratio and perfectly linear frequency response transmit and amplify the
microphone signals truly unchanged.
OctaMic II offers 8 balanced XLR mic / line inputs via Neutrik XLR/TRS combo jacks. Each channel contains switches
for 48V phantom power, a low cut filter and phase reversal. Amplification can be set between 6 and 60 dB. LEDs
for signal, clip, and activated phantom power give a complete overview on the unit’s status. When the special Clip
Hold mode is activated, any detected clipping will cause the corresponding LED to flash once per second. With this,
the user gets a long-term peak detection, and no longer needs to constantly watch the LEDs. At the same time
momentary overloads are still displayed correctly. The balanced line level output signal is available at the back of
the unit via 8 stereo TRS jacks.
