FCL (Feedback Channel Locating) lamp
This lamp is used during setup to identify any channel
that might be howling. Check these lamps when setting
up for a performance. If the lamp lights up, adjust the
channels equalizer 2 or level knob 5 to reduce the
level so that the lamp goes off.
Input of a continuous sound (as from a CD player or
NOTE
vocal) may cause the lamp to come on even in the
absence of howling.
2
Equalizer (HIGH, MID, and LOW)
This three-band equalizer adjusts the channel's high,
mid, and low frequency bands. Setting the knob to the
position produces a flat frequency response. Turning the
knob to the right boosts the corresponding frequency
band, while turning to the left attenuates the band. The
following table shows the equalization type, the base fre-
quency, and the maximum cut/boost for each of the three
bands.
Band Type Base Frequency
HIGH Shelving 10 kHz
MID Peaking 2.5 kHz
LOW Shelving 100 Hz

MONITOR control
Adjusts the level of the signal sent from the channel into
the MONITOR bus. If input is from a stereo channel pair
(5/6, 7/8, 9/10, or 11/12), the signals from the L and R
channels are mixed before moving into the bus. The
MONITOR bus signal is output at the MONITOR OUT
jack O, and may also be output from the SPEAKERS A
jacks V (depending on the setting of the POWER AMP
switch R).

the EFFECT bus. If input is from a stereo channel pair
(5/6, 7/8, 9/10, or 11/12), the signals from the L and R
channels are mixed before moving into the bus. The
EFFECT bus signal is fed both to the internal digital
effector and to the EFFECT OUT jack C.
