of the switch. With the switch in the up position, the input sig-
nal bypasses the EQ section and continues unmodified.
EQ Sections
These controls are used to modify the tonal quality of an audio
signal. All Century Series consoles have a four-band EQ sec-
tion on each input module. The effect return sections, within
the group modules, have two-band EQ sections. Within an
input module, the EQ section will affect the signal only if the
EQ IN button is depressed.
EQ Control knobs - Fixed EQ:
When there is only one knob, it controls the boost or cut of a
fixed frequency range. The SP input modules and all effect
return sections have these single knob/fixed EQ controls.
EQ Control knobs - Sweep EQ:
When there are two knobs, the inner knob controls the boost or
cut as in the fixed EQ, while the outer knob controls the center
frequency adjusted by the inner knob. These center frequencies
are printed on the module around the outer knob. The GT input
module has the frequency sweep knobs on all four bands,
while the TC input module has them only on the mid-frequen-
cies.

External Talkback Input Switch
This switch disconnects the two regular talkback microphone
inputs and switches on the external talkback input XLR found
on the rear panel of the GT master section.
External Talkback Output Switch
This switch activates the external talkback output XLR. The
signal fed to the connector is the same signal being sent to the
talkback assignments.
Fader
The fader is used for primary level control of the channel,
except those Aux output sections selected to a pre-fader posi-
tion. (The Insert output level is not affected by the fader posi-
tion.)
Optimum noise performance is achieved when the fader is
operated near the 0 fader position and all gain controls are
properly set. This does not mean that all channels should be set
at 0 . Proper mixing requires varying of at least some of the
faders. The 0 point should be considered a reference, with all
volume changes taking place between the -10 and 0 reference
points at normal desired levels. For effect, faders may be oper-
ated below this level, provided no faders within the group or
master section are increased in level to compensate for the
input’s lower fader setting.
Fader Reverse Switch
This switch swaps roles between the Effect Return Level pot
and the Subgroup Fader. When depressed, this switch causes
the Effect Return Level to be controlled by the Subgroup fader,
and the Subgroup level to be controlled by the Effect Return
Level pot. If you want the control of the fader when setting
effect returns, this switch is particularly helpful. A red LED
indicator is provided to the left of the switch and illuminated
when the switch is depressed (reverse mode).
Gain Control
This knob adjusts input gain circuitry for proper electrical
operation. Adjust this control by monitoring signal present
(green) LED for bright intensity, with peak (red) LED flashing
only occasionally when the loudest program material is pre-
sent. When a PFL switch is depressed on an input channel, this
signal can be observed on the Left/Right monitor meters within
master module. When using this method for adjustment of the
Gain Control, normal signal level should be adjusted to show a
level between -9 VU and 0 VU. Constant distortion on an input
channel could mean that the input channel is being overdriven.
Check for improper input gain adjustment first.
Group Assignments
See BUS ASSIGNMENT SWITCHES
Group Meter
Located at the top of each subgroup module, this ten-segment
LED meter monitors the post-fader output of the group.
Similar meters on the Master Section monitor Left and Right
outputs.
Group XLR Switch
This switch assigns the post fader group signal to the group out
XLR located on the rear panel of the group module.
Headphone Jacks
Located at the top of the master section and under the right
side of the hand rest, these jacks provide a pre-fader stereo
headphone level output of the Left and Right outputs. When
anything on the console is PFL’d or AFL‘d, the R+L output is
replaced by whatever is PFL’d/AFL‘d.
Headphone Level Control
This control adjusts the level of the signal fed to the two head-
phone jacks; located in the upper right portion of the master
section, just below arm rest on the far right side.
HF Peak/Shelve Switch
This switch is used for switching the high frequency EQ con-
trol between the normal shelving setting to a peak setting.
High Pass Switch

HMF EQ Control

Insert Jack
This jack allows you to access a point in the channel’s electri-
cal circuit for inserting an external signal processor. The output
level of this connector is designed to drive the inputs of most
external signal processing equipment and to accept the result-
ing output signal. When a properly wired TRS plug is inserted
in this jack, the input signal path is broken after the gain stage
and high pass filter. The return signal is fed to a point just
before the EQ section. See the Connections and Conventions
section in the front of the manual for specific information on
plug polarity and signal assignments. (This jack could be used
to connect an effect with an unbalanced 1/4" connector; how-
ever, the signal path would be broken, leaving the remainder of
the input module unused, and the effected signal would need to
be returned to the console via an unused input channel. A
