861 Product Firmware Release 4.25 (2007-02-07)
New Features
- RS232. "SO" emulates the source key.
- DSP. Automatically applies filtering for Meridian passive inwall and onwall speakers to optimise their bass response (requires latest configuration program).
Software Fixes - Critical - Software must be updated
None
Software Fixes - Useful - May be useful to upgrade but not essential
- Bass. Large analogue speakers and subwoofers had reduced bass levels with v4.24. This is now fixed.
Software Fixes - Minor - Update probably not necessary
- RS232. Faster response to repeated RS232 commands from home automation systems.
- RS232. Extended lipsync range (0ms to 85ms) now available with APxxnn as per other menus; xx is "4C", nn is "00" to "AA".

861 Product Firmware Release 4.2 (2005-04-22)
New Features
Local presets
The 861 retains a copy of the preset currently selected for each of the four stream types (music, movie, 2 & 6 channel). When any menu value is changed or the preset is changed then the local copy is updated. This means that changes to presets are not lost when the stream type changes, e.g. moving in and out of menus on a DVD. The settings are not stored until either the preset is 'stored' or the preset is 'assigned' to the source. Reselecting the source reloads the default assignments.
Lipsync
The range of adjustment for Lipsync has been increased from 30ms to 85ms. This gives users more flexibility when trying to time align sound and video. The setting is also now adjustable per source, rather than per preset - this is to reflect the shift of video processing from the display device to the source device. When the user changes the Lipsync value it is immediately stored for that source, there is no need to use the 'store' keys.
RS232 commands
"ON" is a new command that emulates the front panel 'on' button. The product will leave standby and select the previously selected source.

Calibrate
The size setting no longer ramps - instead all relevant speakers are set to size zero on entering size calibration. There is a pause in between each channel to allow the bass protection to stabilise. Moving between speakers within the routine does not return the sizes to zero, but if you exit size calibrate and re-enter then they will be zeroed again. Note that this may give the false impression that size is not being stored - particularly where there is only one channel, like a subwoofer, to adjust.
Triggers enabled in calibrate
The settings for the first valid source are used to determine which triggers go to which voltage level in the calibrate procedure.
PC control
Copy source selection is allowed when the main room is in standby. Use "COxx", where xx is a number, 0 to 13. '0' to '11' are the sources; '12' is mute; '13' is copy source.
Tape card
Cleaner audio switching for the first source after a reboot.
Headphone
Headphone volume control is allowed in standby ("vm" & "vp"). Also, the headphone output has direct volume control, use "VCxx" where xx is the volume from 1 (or '01') to 99.
DSP presets
DSP presets can now be cleared from the serial port, use "cl" (function clear emulation).
MSR+ emulation
"DS" = DSP preset key; "ds" = fn. DSP; "ff" = fn. fast forward; "fb" = fn. fast back; "RE" - red key; "GR" = green, "YE" = yellow; "BL" = blue.
Sinesweep
This feature now has a maximum start volume of 50. The signal is a full scale sine wave, and may be significantly louder than whatever source was playing beforehand.
Menus
The 'Meridian DVD player present' flag is now always set. This gives consistent functionality across 800 series and G series products. This means users will have to use the function key as well as the menu up/down/left/right, display and store/clear keys.
Comms
The 'wire sense' feature has been removed in order to be consistent with other 800 series and G series products. If a 'not-controller' product is removed from a system then an auto setup must be performed (press 'Clear' on the MSR or MSR+ when the product is in standby) before it will respond to IR commands.
