User manual ART TCS

[. . . ] ART TCS Twin Compressor System IMPORTANT SAFETY INSTRUCTION ­ READ FIRST This symbol, whenever it appears, alerts you to the presence of uninsulated dangerous voltage inside the enclosure-voltage that may be sufficient to constitute a risk of shock. This symbol, wherever it appears, alerts you to important operating and maintenance instructions in the accompanying literature. Read manual. Read instructions: Retain these safety and operating instructions for future reference. Heed all warnings printed here and on the equipment. Follow the operating instructions printed in this user guide. [. . . ] Thus, more of the signal will be affected by the NR. The Shelf control tunes the Noise Reduction detection circuitry such that it is less sensitive to certain frequencies. When fully counterclockwise the noise reduction is most sensitive to lower frequencies, and when fully clockwise the noise reduction is most sensitive to higher frequencies. -7- ART TCS Twin Compressor System 5Bypass, Tube, Det. Loop Switches ­ These 3 switches control the channel settings. When depressed, the BYPASS switch completely bypasses the compressor controls, including output level (It should be noted that this is an active bypass, so if the unit is unpowered no signal shall pass through). The TUBE switch places a 12AX7 tube in the signal path adding tube warmth and gain. The DETECTOR LOOP switch selects the rear inserts for the detection path. This routing is useful for ducking and voiceover techniques. 6V3 Compression Selector ­This selects the V3 setting for the given channel. 7LED Meter and Source Selection ­ This LED METER bar graph shows either the input or the output average level (with a peak hold). The source for the meter is determined via the LED METER SWITCH. 8Output Level ­ These knobs function as either dual output level controls or stereo output and pan controls. 9Stereo Link ­ When engaged the unit functions in Stereo Mode. While in this mode the LEFT CHANNEL CONTROLS act as the global controls for the unit with the exception of the detector loop controls. Gain Reduction Meters ­ These VU meters show how much gain reduction is taking place. When set at 0 there is no compression, and as compression increases, the VU meters move "down" displaying the gain reduction in dB. -8- ART TCS Twin Compressor System REAR CONNECTIONS 1Rear Input Jacks ­ The TCS features both ¼ inch and XLR connectors on the back as inputs wired in parallel. The rear input jacks accept line level signals up to +20dBu. The rear inputs of Channel 1 are disconnected whenever the front panel ¼" jack is used. This allows you to keep the rear inputs connected in a rack installation and override Channel 1 when you plug into the front panel ¼" jack. 2Rear Output Jacks - The TCS features both ¼ inch and XLR connectors on the back as outputs wired in parallel. 3¼" Detector Loop Inputs (Rear) ­ The TCS features 2 detector loop inputs on the rear that accept line level signals. These are useful for ducking and voice over applications (the voice signal coming in must be line level, TS jack for override, TRS jack for loop insertion) -9- ART TCS Twin Compressor System OPERATION Compression Basics ­ Compression is an effective way to gently control the dynamics of a signal. The most important setting in your compressor is the threshold. [. . . ] The OPL settings will allow the VCA to limit any peaks, and have the opto-isolator carry out the leveling compression. - 17 - ART TCS Twin Compressor System WARRANTY INFORMATION Limited Warranty Applied Research and Technology will provide warranty and service for this unit in accordance with the following warrants: Applied Research and Technology, (A R T) warrants to the original purchaser that this product and the components thereof will be free from defects in workmanship and materials for a period of three years from the date of purchase.
