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.

CENTURY SERIES SP / TC / GT Feature Overview The SP / TC / GT features listed below are common to all Century Series Consoles. • SSM/PMI High quality preamplifiers on balanced microphone/line inputs and on all balanced outputs for uncompromised audio quality and reliability. All IC’s within the audio path are socket mounted for easy upgrade or service.
CENTURY SERIES SP / TC / GT Wiring Conventions Since the same connectors are used throughout the professional audio industry, it is important to know how the connectors for Crest’s Century SP, TC, and GT consoles are wired. The wiring is as follows.
CENTURY SERIES SP / TC / GT Century Series Console Power Supply Century Series Consoles use a separate rack-mountable power supply which provides the specific voltages used by each console. Crest Audio’ Century Series makes use of two different power supplies. The model and frame size of your particular console determines which of the two supplies should be used.
CENTURY SERIES SP / TC / GT Power Connections The connections to and from the power supply vary depending on your specific configuration. Before setting up the console, always check to make sure the AC voltage marked on the power supply agrees with the local supply. Always connect the console to the power supply before switching on the power supply. Do not run the power supply if it is not connected to the console.
CENTURY SERIES SP / TC / GT System Connections The console is the hub of a sound system and because it controls most of the variables within a system, proper connection and component relationships are vital to assure accurate operation and results. The following diagrams illustrate conventional system connections.

CENTURY SERIES SP / TC / GT SP/TC/GT USER-OPTIONS SP, TC, and GT consoles are shipped having standard configuration unless specified at time of order. These are ways that the console configuration may be varied after manufacture. The items listed are internal options selected by gold jumper links. Default is marked with a line on the board and is usually pins 1&2 of the three pin header. In addition there are links for module function assignment.
CENTURY SERIES SP / TC / GT Console Disassembly Though you shouldn’t have to disassemble the console, it is necessary to remove modules to change the jumper and switch settings associated with the internally selectable options. The following steps detail the tasks involved when taking the console apart. ONE • Open the armrest Opening the Armrest To properly remove one or many modules, the black painted armrest must first be opened.
SP TC GT Appendix B Glossary
SP / TC / GT CENTURY SERIES 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 content 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 microphone by way of its microphone stand.
CENTURY SERIES of the switch. With the switch in the up position, the input signal 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 section 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.
CENTURY SERIES SP / TC / GT stereo (TRS) plug can be used with the Tip & Ring tied together to access the channel signal pre-EQ). Internal Oscillator The GT master section has a 1 kHz internal oscillator. This oscillator can be used as signal source to run tests, diagnostics or calibrations. The oscillator can be assigned to all Groups, Auxes and Matrices via the Talkback assignment switches.
CENTURY SERIES SP / TC / GT seen on the Left/Right/Monitor meters, and can be heard both in the mixer’s headphone output and on the rear panel monitor output of the console. When the PFL Switch is depressed, the channel PEAK LED indicator illuminates at a low intensity. When used as an indicator of switch position, the Peak LED indicating circuit remains fully operational by illuminating at a much higher intensity than its use as a status indicator.
