Operation

To some ears the impact of the wrap cir-
cuit may seem subtle, and this is normal.
Remember that how audible the wrap
effect will be varies with the acoustics of
your listening room, the output settings
established during the calibration process,
the system volume and the type of pro-
gram material in use.

Note that the Wrap circuit is not in use
when the 

˜

displays 

the two lights connected by the REF 
bar along with the center, front and 
middle LED.

When the 

buttons 

ˆo

are

pressed when the AVR40 is in the 

mode, the circuits are adjusting a con-
trolled amount of level into the rear
channels. The amount of this change
will be indicated in the 

. Note that the range of control

for the Wrap circuit in the 

mode

will vary depending on other system
settings, and you may find that the
setting cannot be adjusted below a
“+4dB” indication.

The AVR40’s tuner is capable of tuning
AM, FM and FM Stereo broadcast sta-
tions. Stations may be tuned manually,
or they may be stored as favorite station
presets and recalled from a 30 position
memory.
