Meridian G68 Product Firmware Beta Release 1.27b (2005-01-31)

New Features

This version of software supports the AAC DSP processing available on newer versions of the G68, along with the alternative of decoding to zone2/copy - earlier software versions willnotfunction with the AAC decoder fitted. To determine if a product has an AAC decoder press the display key in standby to view the software version numbers. An additional display will appear between the "Micro" screen and the "DSP" screen - "+ AAC/Zone2 decoder" - if the hardware is present.

Support for G68J - this version of software automatically re-routes sources assigned to O1, O2 & the internal tuner when the inputs are not present. The G68J will select O3, O4 and A1 respectively.

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.

Gain adjustment for internal tuner. Each preset radio station can now be assigned an audio level gain value. This is to give the same perceived loudness for each station. The setting can be changed before or after a 'store' sequence: it is automatically stored for the current station. Note that this occurs in the digital domain and clippingispossible if the user applies positive gain to a loud station.

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 - Software must be updated
None

Software Fixes - Useful - May be useful to upgrade but not essential

Zone outputs. Zone3 variable volume is initialised to volume 65, rather than zero. The zone2/copy and zone3 diagnostic displays are now available via the serial interface; use "CS71" and "CS72" for zones 2 and 3 respectively. Optical inputs O1, O2 & O5 are now available on the zone2/copy and zone3 outputs. S-video to composite mixdown and diagnostic fixed.

Surround subs. The surround sub is now present in the calibrate procedure and the analogue output level has been corrected.
PC Control. The G68 now correctly outputs the volume number in the "!V65" format when requested.

Software Fixes - Minor - Update probably not necessary

None
