CASCADE (switch 2)
This switch determines the use of the audio signals
received at the
CASCADE IN
connectors
W
when
the
CASCADE
key
F
is activated.
In the
EXC
(exclusive) setting, the input cascade
signal replaces the direct input signals at both the
LINE OUTPUT
X
and
SPEAKER OUT
Z
terminals.
In the
SUM
setting, the cascaded signal is summed
(pre
ROOM LEVEL
) with the direct input signals
from the
LINE OUTPUT
X
and
SPEAKER OUT
Z
terminals (as well as the
MEETING OUT
Y
and
PHONES
J
).
NOTE
Remember that this only applies to audio signals. You
cannot cascade video signals using the AV-452.
The cascade and intercom
Note also that
when the switch is set to the
EXC
(exclusive) setting,
the CV intercom input is disabled. The front panel
INTERCOM
key
G
will not light if the switch is set
to
EXC
. Also, when the switch is in this position,
pressing the
INTERCOM
key will cause the key to
flash briefly, indicating that the intercom input is
disabled.
SPEAKER OUT (switch 3)
This switch determines whether the signal sent to the
SPEAKER OUT
Z
terminals is the same from both
speakers (left and right summed) (
MON
) or whether
it is a stereo signal (
ST
).
If the mono option is chosen, it is possible to use the
AV-452 to control the sound fed to either or both of
two rooms, switchable using the
AMP
keys on the
front panel
I
.
NOTE
This switch setting only affects the speaker outputs. It
does not affect the
LINE
outputs
X
, which are
switched between mono and stereo with a dedicated
switch
e
.
MIC HPF (switch 4)
This switch enables or disables an 80 Hz high-pass
filter added to the summed microphone signals.
Use this filter to cut out wind noise, floor rumble, etc.
from microphones which are located in less than
acoustically perfect environments.
INTERCOM GATE (switch 5)
This switch enables or disables the intercom squelch
circuit (noise gate).
When this switch is in the
OFF
position, the
GATE
THRESH
trimmer pot

has no effect.
AV DUCKER (switch 6)
This switch enables or disables the AV ducking
circuit.
When this switch is in the
OFF
position, neither of
the
AV DUCKER
trimmer pots: the
RATIO
or
THRESH
c
controls, has any effect.
