RME OctoMic II - provides 8-Channel 192 kHz / 24 bit AD conversion
with eight hi-class microphone and line pre-amplification channels,
featuring a combination of sophisticated components and approved
Lowest distortion, excellent signal to noise ratio and
perfectly linear frequency response transmit and amplify the microphone
The OctaMic II includes some significant enhancements compared to the OctaMic:
- The balanced TRS inputs of the Neutrik Combo XLR jacks are
phantom power-free and can be operated as real line inputs too.
The improved design of the input circuits allows for a maximum
input level of +21 dBu with a convenient gain range from 6 dB up to 60
- Improved signal to noise ratio (SNR) ADC 107.5 dB
- Improved THD, especially at higher gains
- Optimised heat dissipation by a new and larger housing with improved convection
- Internal wide range power supply with line filter, insensitive to voltage fluctuations
- Super-stable, short circuit proof 48 V phantom power
OctaMic II offers 8 balanced XLR mic / line inputs via Neutrik
XLR/TRS combo jacks. Each channel contains switches for 48V phantom
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 clip-state 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
Frontside switches include power on/off and output level, for a
choice of -10 dBV, +4 dBu or Hi Gain (+19 dBu) as reference level.
This unusual feature offers two advantages. First, the reference
level can be easily switched to match any of
RME's current interface devices, from HDSP 9632 through
Multiface up to the renowned ADI-8 series converters.
Second, the Signal to Noise ratio is optimized, and the Clip-LED
will exactly match the ones of the ADI-8 (2 dB below 0 dBFS).
The balanced line level output signal is available at the back
of the unit via 8 stereo TRS jacks.
The specially developed, internal hi-performance switch mode power
supply lets the OctaMic II operate in the range of 100V to 240V AC. It
is short-circuit-proof, has an integrated line-filter, is fully
regulated against voltage fluctuations, and suppresses mains
The 8-Channel AD-conversion of the OctaMic II operates at up to
192 kHz. The digitized signal is available simultaneously at the double
ADAT output (S/MUX, up to 96 kHz), and at a DB-25 connector (4 AES/EBU
outputs, up to 192 kHz).
The digital part can be clocked internally (master) and
externally via word clock, AES/EBU and SPDIF.
RME's outstanding SteadyClock(TM) ensures perfect AD-conversion, as
jitter on the external sync-sources is nearly completely removed.
All settings are done via DIP-switches on the back of the
OctaMic II. Analog outputs and both digital outputs operate fully
The choice of reference level affects the analog outputs only,
the signal/clip indication and the AD-conversion will react only to the
8 balanced XLR/TRS mic/line inputs
