Digital Setup

Note to H8000FW users: many of the screen shots in this section are taken from the H8000. Your screens will differ insofar as you have four plus eight AES/EBU inputs and outputs, not eight. This discrepancy shouldn’t matter.

DIGITAL SETUP OVERVIEW

Before we look at the H8000FW’s digital setup in detail, let’s take in the "big picture."

The H8000FW sports twelve AES/EBU inputs/outputs, two S/P DIF inputs/outputs, and eight ADAT input/outputs as well as 16 channels of FireWire.

All of the H8000FW’s analog to digital conversion and digital to analog conversion is 24 bit.

Only eight external inputs can be connected to DSP A and B.

Whatever signal is sent to AES/EBU output 1/2 is also sent to S/P DIF output 1/2.

Whatever signal is sent to AES/EBU output 11/12 is also sent to S/P DIF output 3/4.

The H8000FW assumes that signals at the digital inputs are 24-bit. No harm occurs if the input is in fact less than 24-bit; subsequent processing will usually fill the lower bits.

The system sampling rate is derived from either an internal clock or an external clock.

The internal clock rates supplied by the H8000FW include 44.1kHz, 48kHz, 88.2kHz, 96kHz (note that 32kHz and 44.059kHz are not supplied).

Unless the sample rate conversion option is ON ("bottom" page under [clock] in the SETUP area), you must ensure that any signal at the AES/EBU 1-4 inputs or S/P DIF 1-2 inputs is synchronized to the system sampling rate.

You must always ensure that ADAT and AES11-17 inputs are synchronized to the system sampling rate – these have no available sample rate conversion.

On the H8000FW, the external clock may be taken from AES/EBU inputs 1117, S/P DIF inputs 3/4 or the ADAT or FireWire inputs. If they are used, AES/EBU inputs 1-4 and S/P DIF inputs 1/2 must be synchronized to the
