The OctaMic II integrates an 8-channel 192 kHz / 24-bit converter with eight high-quality microphone channels, equipped with the finest components and proven RME technology. Minimal distortion, an outstanding signal-to-noise ratio, and a linear frequency response transmit and amplify microphone signals absolutely untainted, ensuring an authentic sound.

The OctaMic II offers 8 balanced mic/line inputs via XLR connectors. Each channel features individually switchable phantom power (48V), a low-cut filter, and phase inversion. The gain is adjustable from 6 to 60 dB. Once the special clip-hold mode is activated and clipping is detected, the corresponding clip LED starts blinking once per second. This peak monitoring mode saves the user from constantly watching the clip LEDs. Nevertheless, all acute overloads are displayed correctly.

On the front panel, there are switches for power and the selection of the reference level, which can be set to -10 dBV, +4 dBu, or Hi Gain (+19 dBu). This unusual feature has two advantages. Firstly, the reference level can be easily adapted to all current RME devices, from the HDSP 9632 to the Multiface and the high-quality converters of the ADI-8 series. Furthermore, the signal-to-noise ratio is optimized, and the clip LED operates exactly like that of the ADI-8 (2 dB below 0 dBFS).

On the rear panel, the microphone signals are available with balanced line level at 8 stereo jack sockets. The specially developed internal high-performance power supply for the OctaMic II operates in the range of 100 V to 240 V AC. It is short-circuit proof, features an integrated power filter, completely regulates voltage fluctuations, and suppresses power disturbances.
