Loading EQ 96kHz<br />

THE EQUALISATION TOOLS<br />

Each stream carries either the odd samples or the even samples<br />

of the 96kHz data. These odd and even data streams are input<br />

to the EQ via a synchronous AES/EBU digital input module.<br />

The EQ 96kHz processes the signals in parallel, with the<br />

resultant signals being passed out of the <strong>Huron</strong> as a pair of odd<br />

and even 48kHz signals. The final output signal is derived by<br />

combining these interleaved samples via a digital to analogue<br />

converter external to the <strong>Huron</strong>.<br />

Figure 92 — Patching the EQ 96kHz tool correctly<br />

When loading EQ 96kHz the following guidelines should be<br />

used to prevent errors occurring in the output signal:<br />

The 96kHz EQ should be the first DSP using application loaded<br />

into the VRack.<br />

The 96kHz EQ should load all of the DSP resources it requires<br />

before any other applications that utilise DSP’s are used.<br />

If it is impossible for the 96kHz EQ to be the first application<br />

using DSP’s loaded into the VRack, it is important that EQ<br />

96kHz is started when the DSP usage count is 4,8,12,16 etc.<br />
