Important Note
Versions 1.x, 2.x, 3.x and 4.x of the 861 Surround Controller have hardware differences. Introducing a version of firmware whose major version differs from that of the product will render the controller inoperative .
Before updating, check your current version and select 1.x, 2.x, 3.x or 4.x firmware as appropriate. If in doubt, consult your dealer.

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 4.24 (2006-12-11)
New Features
None
Software Fixes - Critical - Software must be updated
None
Software Fixes - Useful - May be useful to upgrade but not essential
- Triggers. No longer affected by busy comms activity.
- APxx features. Feedback on RS232 corrected.
- IA40. More reliable when switching to the IA40 from an encoded stream (e.g. Dolby Digital 5.1).
- Sinesweep. During sinesweep the display is updated more frequently.
- DSP speaker latency. This is now assumed to be identical across all speakers - as per the latest released code for all speakers.
Software Fixes - Minor - Update probably not necessary
None
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.
Software Fixes - Critical
None
Software Fixes - Useful
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.

关于不同版本升级
861 Surround Processor
See notes above on Firmware delivery and installation.
Important: check your current version and only update to the same major version! 861 versions 1.x, 2.x, 3.x and 4.x have hardware differences; if you attempt to load firmware for a different version you will disable the product! You may update 1.x to 1.8, 2.8 to 2.81, 3.x to 3.51, 4.0x to 4.1. You cannot upgrade from 3.x to 4.x without a hardware update: please contact your retailer.
也就是说v2->v3 是不行的
v2.8 升级到2.81 是可以的, 如何确认861版本
Check the version number in your product by pressing 'Display' in standby

Bass. Large analogue speakers and subwoofers had reduced bass levels with v4.24. This is now fixed
几个我遇到的问题, bass 输出偏轻. 极限范围为+6 . 不过通过版本升级 可以解决
There is a new option for LFE subwoofer in the music layout, customers expecting correct playback of DVD-A material should select this option for their Music layout if they have a subwoofer.
版本升级,多一个lfe 通道. 861 也是支持3个低音炮的, 一般可以选择 左右 , 左中右 或者低音炮辅助环绕系统
The new section requires the customer to carefully set the ‘Size’ parameter for each ‘Large’ speaker that isn’t a Meridian DSP loudspeaker.
关于喇叭设置的一个bug , 遇到过, 如果不是meridian dsp 喇叭, 设置large 无法选择喇叭尺寸口径 |
