User manual PHONIC MM1002

[. . . ] Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. Do not defeat the safety purpose of the polarized or grounding-type plug. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet. Protect the power cord from being walked on or pinched particularly at plug, convenience receptacles, and the point where they exit from the apparatus. [. . . ] The graphic shown indicates that the user has set the level range at 50~110 SPL, A weighting. The max level during the time of measurement is 105. 5 dB, The user is reading at 1 kHz, which has a dB SPL of 102. 8. If you would like to store the measurement data in the memory of MM1002, go to the STORE menu. Users can save the measured spectrum data into one of the ten memories. Scroll through the various values located in the 'Hz' box until you come to a flashing ESC. Press enter to exit RTA mode. RTA (Real Time Analyzer) - Accoustic This function analyzes the audio received through either the built-in mic or Line In connection, divided into 31-bands at 1/3 octave intervals, and displays the relevent information on a bar graph that shows the decible level of each band of sound from 20 Hz to 20 kHz in four different response times (35 ms, 125 ms, 250 ms, and 1 sec) and in three weighting types (A weighting, C weighting and Flat). For more info on response times and weighting, please consult the appropriate sections. SPL (Sound Pressure Level) Meter This feature of the MM1002 gives users an accurate measurement of the overall "loudness" of their sound, measured in decibels (dB). This is a true RMS-measurement, using standard display time average, and standard A, C, and Flat weightings. WEIGHT RANGE 50 ~ 110 SPL A MAX 99. 2 Procedure: 1. After the start up sequence of the MM1002 is complete, the real time analyzer will appear on the LCD screen. Go to the SETTING menu to set the appropriate weighting, level range, response time, or other relevant properties. Press ENTER again on the highlighted VALUE to view the value of each center frequency. When differently weighted items are attempted to be averaged, a warning will appear onscreen advising users to select again. RTA (Real Time Analyzer) - Electrical Signal By simply connecting an XLR jack to the MM1002's in jack, the RTA function can accurately measure your signal. Procedure: 1. Enter the SPL/LINE menu and set the measurement unit to dBu, dBV, or voltage, as required. Send a signal through the MM1002's female XLR jack (Pin 2 - Hot; Pin 3 - Cold; Pin 1 Ground). Go to the SETTING menu, where you may want to adjust the RANGE, WEIGHTING, RESP TIME (response time), or MAX LEVEL of your measurement. If all frequency readouts are needed, press "ENTER" button (or the jog control) for two seconds to enter line level meter. page 12 MM1002 User's Manual PHONIC CORPORATION Level Meter Measure the line voltage level in units of dBu, dBV, and AC voltage, using standard response time, and standard A, C, or flat weightings (under normal conditions, flat is preferable). Using the MM1002 to meaure DC voltage may damage the MM1002 and will void the warranty. MEMORY The sub-menus of MEMORY include: STORE, RECALL, AVERAGE, EQ SETTING. Through these options, users are able to store their RTA measurements. Store The user can save up to 10 sets of measured data (1 to 10), as well as 6 averaged sets (A to F), into the memory of the MM1002, allowing them to be used later for further analysis or uploading to your computer.

Enter the SPL / LINE menu and set the measurement unit to dBu, dBV, or voltage, as required. You may select a range level, weighting, response time or a maximum level by going into the SETTINGS menu, then onto the appropriate menus. The selected values of these options will be displayed above the RTA on the MM1002's default screen. On the main RTA display, hold the ENTER button for approximately 2 seconds to activate the Level Meter screen. [. . . ] The functions being activated will show both on the MM1002 and the PC or laptop. Go to FILE and click ON LINE once more if you need to disable the MM1002's online operation. Installing the MM1002 software: Using the MM1002 on line: 1. Find paa3_setup. exe on the disc and double click to begin installation. Select an appropriate installation directory and click "next" to continue. [. . . ]
