Crane Song AVOCET II - Manual (Page 36)

D/A Converter
Starting with Sn A682890 we switched to a new SRC in the D/A converter. This D/A is a big improve-
ment in sound quality. This is an upgradable item. In units with serial numbers of A682840 and less it
will require some soldering skills. The later units it is plugin.
Upgrades
Upgrades are factory direct only in the US and in the rest of the world by the local Crane Song
distrubition company.
REV7 FIRMWARE, REV7 D/A
Sarting with the rev 7 D/A board rev 7 firm ware is installed in both the main unit and the remote.
both units must contain the same rev.
If a rev4 or later system has this frimware installed it should be fine.
In other words rev4 and later main boards with the surround remote will run rev7 firmware
The remote must be a surround version
In order to upgrade to the rev7 D/A
the wrap need to change, the digital out requires an extra hole.
This D/A is in units starting with Sn. A683041. The rev7 D/A has the same time delay as as the rev6
and later D/A so they can be mixed in a surround system.
However only rev7 and later has the metering digital output.
THE CHANGES
1. Output #3 can work in parallel with outputs 1 or 2. This is for thoese who need only 2 outputs
and have the desire to turn a sub woofer on or off, the OUT 3 button cab be programmed to allow this
type of operation. Note that when setting up the type of speaker system, stereo or surround, the
system switches to non sub woofer mode. You will then need to reset this mode if you desire it.
At this time, there is not any writting on the front panel for this function
2. The remote talk input is now non latching. This is available on the db 25 connector.
The talk button on the remote will latch if pushed for less than 0.5 seconds, If it is held
for more than 0.5 seconds it will be non latching. The remote input and the button on the remote can
over ride each other.
3. A digital meter output has been added. This is an AES output on a DB-9 connector
which also allows of meter sync in surround mode. It requires a specially made cable
