CENTURY SERIES SP / TC / GT

GLOSSARY

The following glossary explains the features and functions found on Century Series front of house consoles.

80Hz High Pass Switch

When depressed, this switch attenuates all low frequency con- tent at a 12db per octave rate referenced to 80Hz. This control is useful with live microphones, as it helps reduce undesirable low frequency "rumble", usually is transmitted to the micro- phone by way of its microphone stand. High quality micro- phones employ internal shock mounts which lessen this prob- lem, but it still remains to some degree. If this material is not removed, the low frequency content tends to make the amplifi- er and speaker systems work harder.

100mm Fader See Fader 48 Volt Phantom Power

This switch turns on the +48V used to power some micro- phones. See XLR Microphone Input for more information.

Auxiliary 3•4 Switch

This switch toggles the two upper Aux Send controls between 1,2 and 3,4. With the switch up, the two Send controls feed Aux 1 and 2. With the switch down, the two controls feed Aux 3 and 4.

Auxiliary 8 Direct Switch

This switch disconnects the Aux 8 level control from the Aux 8 mix bus and instead is used to control the Direct Output of the channel. Normally the Direct Out jack is post-fader. When the Aux 8 Direct switch is depressed the Aux 8 level control assumes output control of the direct out signal. The Aux 8 con- trol is fed pre-fader.

Auxiliary Bus

The Aux Bus carries signal from the Aux Send controls to the Aux outputs on the rear panel of the Master Section. A typical setup would entail using the Aux 1-4 sends for monitor mixes while Aux 5-8 are used for effect sends. If a separate monitor mixer were being used, Auxes 1-4 could be used for additional effect sends. Effects can be returned via the EFX Return sec- tion of the group modules or through spare input modules.

Auxiliary Mute Switches

The Master Section of the GT consoles have mute switches for each Aux send. When depressed, this switch mutes the corre- sponding Aux Send Master. When the mute is engaged no sig- nal leaves the associated Aux out jack and a red LED illumi- nates to the left of the switch. These mute switches are active only if the Aux Mute Master switch on the Master Module is depressed.

Auxiliary Pre/Post Switch

See Pre/Post Fader Switches

Auxiliary Send Controls

All Century Series consoles employ eight Aux Sends per input channel which send signal to the Aux Bus. These sends are controlled via the six level controls on each input module. Aux Sends 1-4 (orange) are typically used for monitor sends. These are the two switchable Auxes; see AUXILIARY 3•4 SWITCH for more info on toggling between 1,2 and 3,4. Aux Sends 5-8

(green) are typically used for effect sends. Each effect return section has Aux 1-4 Send controls, which could be used for adding effect return signal to the monitor mix. Internal jumpers select between pre/post EQ.

Bus Assignment Switches

Wherever these switches occur, they assign the post Pan pot signals to odd and even mix buses. The Pan pot controls assignment between odd and even mix buses with extreme left assigning signal exclusively to the odd mix bus and extreme right the even mix bus. It is a common practice to assign all effect return channels to a sub group channel. This enables the overall amount of effect signal to be controlled from a single fader location. Between musical numbers, it is possible to turn off the effects with this group fader or group mute switch or to vary the amount of overall effect return in reference to the dry original signals, using the group fader control.

DC Power Indicators

Each Century Series console uses a variety of electrical volt- ages which are fed to the console from the power supply. The status of each operating voltage (+20, -20, +48, +24) is indicat- ed by four LED’s on the master module. If the console ever behaves abnormally, first check these LED’s to make sure that the power supply is providing the proper voltages.

Dim Switch

This GT Master Section switch produces a -12dB attenuation in signal to the local monitor. This feature is useful for tempo- rary lowering of local monitor levels without actually adjusting any pots or faders. (Local monitors are automatically dimmed when Talkback button is pressed.)

Direct Out Jack

Each input module has an unbalanced 1/4 direct out jack. The output from this jack is post-fader unless the AUXILIARY 8 DIRECT switch is depressed. When this switch is down the output is controlled by the Aux 8 pot. See AUXILIARY 8 DIRECT for more information on that switch.

Effect Auxiliary Level Control

See AUXILIARY SEND CONTROL

Effect Return EQ

Each effect return section has a two-band fixed EQ. These High and Low frequency controls are centered at 10kHz and 80Hz respectively.

Effect Return Gain

This control adjusts the gain on the signal returning from the effect. Use the effect return signal present and peak LED’s to set the gain properly.

Effect Return Subgroup Assignments

Much like the switches on each input module, these switches assign the corresponding effect return to any or all subgroups. The Pan control operates in the same fashion, that is; extreme left assigning signal exclusively to the odd mix bus and extreme right the even mix bus.

EQ In Switch

This input module switch, when depressed, inserts the EQ sec- tion into the signal path and illuminates a green LED to the left
