Crane Song AVOCET II - Manual (Page 53)

Avocet alignment
The alignment should not be changed unless you are 100 % positive that you know how to do this
and have very good equipment. If not you could mess up the alignment, and the left - right channel
balance. The gain trims will provide a plus or minus 3 db range, which can allow for different configu-
rations. Do not attempt to adjust this as a way to reduce the output level. If you do you will mess it
up. If you need to reduce the output level use the provided pads. There is 5 db of analog headroom
above the zero or red led on the remote’s meter.
If the rom has surround frimware set it to stereo operation before power up
Jumper JP1 must be installed on power up
This jumper should not be changed with out power down and power up
With Att at max level, 1khz sine wave
Put the signal into analog 1 and mono the unit

ch1 and ch2 should be equal
R166, R167 are the gain trims (CHANNEL GAIN MATCHING)
adjust the output for 1.783 volts in both channels
use 5.1k ohm load on the output, measure the output balanced
turn mono off

adjust the trims for ANA1, ANA2, and AUX inputs they can be reached by small holes next to the xlr
connectors on the back

REMOTE METER ADJUST with max digital input adjust the meter trims for meter full scale
(R165, R166)
DIGITAL METER OUTPUT WITH ANALOG INPUT
