Does anyone know what the latency of the processors is?

I'm using my G68 as passthrough for an Anthem MRX1120 so that I can continue to use my DSP5500 front speakers, and I know one of the last speaker firmware updates set the latency to 8ms and so I can remove about 3ft of distance in the Anthem's speaker layout configuration to account for that. However, presumably the processor also has some latency between the 5.1 analog in and the digital outs that I should also account for - Anthem require manually distance measurements like Meridian.

I'm using Discrete, no MRC, 2.8V analog sensitivity, 87 volume, with all speakers set to 0 distance and volume offset in MConfig.

Cheers,
David.
