subwoofer. Or, when pressed, the filter prevents the
subwoofer from reproducing higher frequency
components of its program material.
7. L/C/R Output HPF switch: This applies high-
pass filters to the Left, Center, and Right Outputs.
The filters are fourth-order Linkwitz-Riley alignments
set at 95 Hz. They should be engaged when the
main left, center, and right loudspeakers are not
intended to reproduce low frequencies in the
program material. The filters are designed for proper
crossover summing with the subwoofer output
signal.
8. L/C Level Setup switch: Press this to listen for
matched level of the left and center speakers. This is
for use during setup; see page #. It applies the
center signal identically to the left and center
outputs, while muting the right output. While the L/C
Setup switch is pressed, the yellow LED will light.
9. C/R Level Setup switch: Press this to listen for
matched level of the center and right speakers. This
is for use during setup; see page #. It applies the
center signal identically to the right and center
outputs, while muting the left output. While the C/R
Setup switch is pressed, the yellow LED will light.
10. Output Level Indicators: Each output control
has an associated two-light level display which
shows the actual output level. The green light
indicates the presence of signal above -20 dBu (80
mV). The red light indicates the clipping distortion of
the audio signal. The green light should flash with
the signal most of the time; the red light should not
light—if it does, the input or output level is too high.
11. SUBWOOFER OUTPUT LEVELcontrol: This
adjusts the gain of the subwoofer output stage so
that its level can be balanced with the rest of the
system. This can often be optimally set simply by
listening while in the center of the listening area.
12. CENTER OUTPUT LEVELcontrol: This adjusts
the gain of the center output stage so that its level
can be balanced with the rest of the system. This
adjustment is part of the system setup procedure.
13. LEFT/RIGHT OUTPUT LEVEL control: This
simultaneously adjusts the gain of the left and right
output stages so that the signal level can be
balanced with the rest of the system. The left-right
balance should be preserved.
14. SURROUND OUTPUT LEVEL control (M86
only): This simultaneously adjusts the gain of the
surround output stages so that their levels can be
balanced with the rest of the system. Once this is
set, the relative balance established with the
amplifier gains will be preserved.
15. POWER indicator: Indicates when ac power is
applied to the unit.
