2.2. Digital Setup

When using the H9000’s digital I/O:

  • Only one of the following protocols may be active at a time: ADAT, S/PDIF Optical, S/PDIF RCA, AES3 XLR, or AES DB25. This is configured on the front panel’s Clock menu page, or in Emote’s Setup View.

  • The optical protocols (ADAT, S/PDIF optical) are limited to sample rates of 44.1kHz and 48kHz.

  • The H9000 does not support sample rate conversion. If you want to feed the H9000 a digital audio signal, the external digital signal and the H9000 must both be locked to the same digital clock, at the same sample rate.

2.2.1. Sound Experiments


The following instructions will show you how to setup your H9000’s digital I/0 using the Sound Experiments factory session. This session uses AES DB-25 connector by default, but the setup process is the same for configuring any of the digital I/O.

  • Connect the H9000’s AES DB-25 connector to your other digital device such as an audio interface.

  • The H9000’s AES DB-25 connector uses the TASCAM standard pinout: https://etide.io/DB-25-Pinout Refer to the Rear Panel section of this manual for details about setting up an AES/EBU connection properly.

  • Load the factory session 906 SOUND EXPERIMENTS. This will automatically configure your digital audio mode to use the AES DB-25 connection, as well as route 4 stereo FX Chains.

  • If you’d like the H9000 follow the sample rate of the other digital device, select “AES Any” as your clock source.

  • Alternatively, if you’d like your other device to follow the sample rate of the H9000, select “internal”, determine your sample rate, and confugre the other device to sync to an external source.

  • You can now process up to eight sources using the H9000’s digital I/O.
