The lt character means go back or exit so click the encoder the highlight will be on the and you will return to the Utilities Function menu Move the highlight to the and click again and you re back to the main menu RuntheRTA Since you re a menu expert now go to Acoustic Analysis and then run the Real Time Analyzer This is a typical Toolbox function and has a lot more fields than the About function had Looking at the top of the screen you will see the letters RTA in a small box This is just the function name gt Change the sub menu Just to the right of the name you will see the word Full This is the sub menu field Not all of the Toolbox functions have sub menus but most do The RTA has two sub menus Full which is 20 20k analysis and Low which covers 10Hz to 332Hz Turn the encoder once to the right or several times to the left and you will highlight the sub menu field Click on it and the screen will re draw the function in Low mode Change back to Full for this demo Change a data field We re going to skip ahead a few fields Unless you are in a fairly loud environment the display will be mostly blank So turn the encoder unitl the dark block is in the lower left corner Now click it will change to an underline You have just entered cursor lock for the RTA dB range field While you are in cursor lock when you turn the knob the data value changes Try it Change the value un
2. Really at this point you know about everything you need to operate the Toolbox You can navigate menus change data values use the cursor and store and recall memories As much as possible all of the Toolbox functions use the same principles of operation so you should be able to apply what you have learned in the other functions also Need to know more Read on there s more 12 Inputs and Outputs Overview The Studio Toolbox gets its input from either the internal microphone called Mic in the Toolbox or the line input jacks which are called Ext These inputs each have different ranges that may be used as required Some functions auto range and others require that you select an appropriate range Depending on need not all ranges are available in all functions The internal microphone has two ranges MicL and MicH Microphone Input Minimum Level Maximum Level Range MicL 30 dB SPL 95 dB SPL MicH 65 dB SPL 130 dB SPL The line inputs XLR and _ combo jacks or the RCA jacks feed balanced input amplifiers with the RCA jacks feeding one side of the balancing network The 3 ranges available for these inputs are Line Input Range Minimum Level Maximum Level ExtL 95dBu 35dBu Ext 75dBu 7dBu ExtH 40dBu 40dBu You may use either the XLR and 1 4 combo input jacks or the RCA input jacks depending on the type of cable you are working with Functions that use only
