Meridian Unplugged - Powered by MrTechGuy.co.uk Forums Discussion Meridian - Systems Mix 16 bit and 24 bit speakers?

Hi tjs,

I went from a 565 to 861v4, and hence my knowledge of “early” 861s is sketchy.

You say you have “an early” 861, I speculating here but it could be that the very first 861s only output at standard resolution and this is why you don`t see the option in any menus or in the documentation.

It would help if you could find out what version of the firmware you have (when in standby press the display button) plus what cards are fitted and post this in you profile signature along with a list of your other kit.

Your plans to have a pair of 5200s at the front with you 5000s now bring up the rear; this will work fine even with “an early 861”. The 5200s (with latest firmware loaded) will upsample and apply the new apodising filters to the standard rate input signal.

After adding the 5200s you should consider updating your centre DSP again a 5200(h/v)c would seem the logical choice.

Some background information for you

Early Meridian DSP like MKI 5000s are 18 bit at standard sample rate 44K/48K.

861s that support 24/96 output always resolution enhance and output 24 bit in SPDIF format. The DSP speakers then use as many bits as they support with the least significant bits (LSBs) being discarded.

The High Speed (HS) flag is a DSP parameter for each DSP mode: DIRECT, Trifield, THX, etc, etc.

HS=N Output 24 bit at standard sample rate (44K1 / 48K)
HS=Y Output 24 bit at high speed sample rate (88K2 / 96K)

Only the 24/96 capable DSP speakers support this higher sample rate.

Have a look on Duncan`s site (see link at the bottom of ever forum page) for both historic and current information on M kit.

Regards,
Carl
