Congratulations on your purchase of a Century Series console. All of us at Crest Audio in Paramus, New Jersey, USA, support your decision, knowing your console contains the finest combination of design and manufacture in the industry. While your new Century Series console is one of the most feature-packed available, great effort has been put into making it simple to operate. This manual explains the functions of your new console, how they operate and how they relate to each other. [. . . ] The aux send section shall include three pre/post fader switches: one for auxes 1-4, one for 5&6, and one for 7&8. The aux sends shall be internally selectable pre or post EQ and pre or post mute. There shall be an Aux 8 direct switch that shall allow the Aux 8 rotary knob to directly control the output of the 1/4" direct output connector. Optional stereo input modules will be available. The console shall be configured in an eight bus arrangement. The effect return section of each group module shall have a gain control, a two-band fixed EQ, sub-group assignment switches, L/R and Mono assignment switches with an LCR configuration switch, aux send level controls for Auxes 1 through 4 with 1-2 switchable to 5-6, and 3-4 switchable to 7-8, a pan control, a level control, a dynamic signal present LED and peak LED, and a PFL switch. 4 scene mute switches (AD) with scene mute safe switch with LED will be available on each return section. The group mix section of the module shall have a pan control, a FET controlled (10 millisecond ramp) mute switch with LED, assignment switches for Left/Right and Mono with an LCR configuration switch. Each group mix section will have balanced (XLR) group insert connections. There will be a send level control for two Matrix mixes (A & B) on each group module with source selection matrix post fader switch. It shall also have a fader reverse switch with LED that allows the group fader to control the level of the modules effect return. A PFL switch, dynamic signal present LED and peak LED, and a 100mm long throw fader shall also be provided on the group module. The master section shall have the following features: eight aux master controls with associated AFL switches and eight aux scene mute switches with LED's, a 100mm long throw fader for each of the Left, Right, and Mono (Center) master outputs, balanced (XLR) insert connections for Left, Right, and Mono (Center) master outputs, an assignable comprehensive talkback system, monitor control (with balanced XLR output), stereo program input section with Stereo EQ, lamp dimming control, and four+two aux scene mute master switch section, each with LED. Two master matrix output sections include level control, Mute switch with LED, AFL monitor switch and peak and signal present LED indicators.

GTx USER-OPTIONS
GTx consoles are shipped having standard configuration unless specified at time of order. [. . . ] In some cases, it may be desirable to derive effect sends pre-fader for special effects, such as those generated by a vocal doubler or harmonizer. The choice of switch position should be determined by the actual situation; though as a general rule, choose the pre-fader position for monitor sends and post-fader position for effect sends.
Q SWITCH (Hi Mid & Lo Mid EQ)
See EQ SECTIONS
RETURN JACK
(See INSERT/RETURN JACKS)
Right Meter
Located on the GTx meter bridge, this VU-type meter indicates the Right output level, post fader.
APPENDIX B
CENTURY SERIES Stereo Program In
The Stereo Program In section (on the GTx Master section) controls the way in which the Stereo Program In signal is routed through the console. Controls for gain, HF/LF EQ, bus assignment (Mono, L/R, Aux 1/2, Aux 3/4, and Matrix A/B buses), balance, level, muting, and PFL are included. Red Peak and green Signal Present LED's are located next to the PFL switch.
