Two headphone jacks
Each headphone output can be programmed with the same or different mixes, with independent front-panel volume control.
Two banks of optical I/O
Connect outboard digital processors, digital mixers or other gear. Two banks provide 16 channels of ADAT optical at 48 kHz, 8 channels of S/MUX optical I/O at 96 kHz or a single stereo TOSLink pair at rates up to 96kHz.
Time code support
Converts SMPTE time code (LTC) to MIDI Time Code (MTC) and passes MTC on to any MTC-compatible host software.
Direct Digital Synthesis™ (DDS)
DSP-driven phase lock engine and internal clock source produces imperceptibly low jitter characteristics (below the noise floor), even when the 8pre-es is resolved to an external clock source via SMPTE time code.
DC-coupled TRS outputs
Use the 8pre-es to manipulate and sequence voltage-controlled modular synthesizers from a host DAW.
Instrument tuner and audio analysis tools
Includes an oscilloscope, real-time FFT, X-Y Plot, and graphic phase analysis.
