User manual AUDIO TELEX SA

[. . . ] The SA Series Mixer Amplifiers are two rack height units suitable for direct rack mounting in a standard 482mm rack format, or desV table mount by means of the rubber feet provided. They are equipped with lour balanced microphone inputs, one line input and two auxiliary inputs (switched). The following informa tion will provide setting up and connectior(iirformation for use in a conventional sound reintorcement system. More detailed information and performance data is available from your dealer or any Audio Telex Communication's oflice. [. . . ] 9. . . . " VU METER " Marked in decibel graduation from +3 to 21 , the light emitting diodes will indicate the volume level at the output of the amplifier. For normal operation the l. e. d. s glow green as they modulate with the output level of the amplifier. lf the lights cunsistently indicate red, the amplifier is being over-driven , resulting in distortion in the quality of the output signal. 8. . . . " POWER " This switch turns on or off the mains power to the amplifier. glows red to indicate the amplifier is turned on.

(see diagram with SA4012 ) , VOTCE OPERATED MUTTNG MODULE TX3010; Automatic muting of ail microphone , tine and auxitiary inputs is possible from microphone input one , which is a designated priority input. Voice operation of a microphone in this input witl cause the module to switch off all other inputs. This function is ideal for muting background music or other sources during paging. To fit the TX3010 module, discunect the mains power and remove the lid of the amplifier by means of the screws on either side . Remove the jumper plug from the socket adiacent microphone input one ( see MIC/LINE INPUT CONVERSION MODULE ; Any microphone input on the 5460 and SA120 can be converted to an extra line input by means of the TX3011. The function is useful for accepting high level paging inputs such as a telephone or telecom line. To fit the TX3011 disconnect the mains and remove the lid. [. . . ]
