User Manual & Firmware UpdatesIntroduction   The ES-9 is a Eurorack 16-in/16-out USB audio interface, with DC-coupled inputs and outputs that can be used for both audio and CVs.With its balanced 1/4" main outputs & headphone socket, it's the perfect one-stop solution for integrating a modular synth and a laptop/tablet, either in the studio or when playing out at a gig. The ES-9's 14 analogue inputs allow simultaneous tracking or mixing of a large number of sound sources in your modular, while the 8 DC-coupled outputs are perfect for controlling the modular with Silent Way, Max/MSP, Ableton's CV Tools, Bitwig Studio or similar, or for sending audio out to the modular for processing.For even more outputs (up to 48 more), the ES-9 can be expanded with the ES-5*. It also has a pair of S/PDIF sockets for connecting other digital audio gear.The ES-9 also provides a pair of MIDI sockets (via a breakout).  * The ES-9 has a dedicated pair of audio channels for the ES-5. Unlike the ES-3 or ES-8, you don't lose audio outputs when using the ES-5. SpecificationsThe ES-9's specifications are as follows:Panel width: 16HPModule depth (including power cable): 50mmCurrent draw: 451mA on the +12V rail, 133mA on the -12V rail (at 96kHz)USB socket: Type CDriver suport: class-compliant USB 2.0 (no driver required for macOS and iOS - Windows drivers provided for Windows 7, 8 & 10)Channel count: 16 in, 16 outSupported sample rates: 44.1kHz, 48kHz, 88.2kHz, 96kHzAudio sample depth: 24 bitAnalogue outputs:8x 3.5mm TS jacks, DC-coupled, Maximum output voltage approximately ±10V2x 1/4" TRS balanced jacks, AC-coupled (main outs)1x 1/4" TRS stereo jack, DC-coupled (headphones)Analogue inputs:14x 3.5mm TS jacks, DC-coupled, Input voltage range approximately ±10VDigital I/O: 1x S/PDIF input (TOSlink), 1x S/PDIF output (TOSlink)MIDI I/O: 1 input, 1 output (on breakout)Expansion headers: 1 for ES-5, 1 for MIDI breakoutPanel controls: headphone volumeInternal mixer: 8x8 crosspoint mixer (can be used with no USB connection for standalone operation)For more detail, please see the user manual.What's in the box ES-9 modulePower cable (16 way, 200mm, keyed)Bag of 4 mounting screws (M3x6mm)A USB cable is not included.
