User manual PHONIC PAA3

[. . . ] IMPORTANT SAFETY INSTRUCTIONS The apparatus shall not be exposed to dripping or splashing and that no objects filled with liquids, such as vases, shall be placed on the apparatus. The MAINS plug is used as the disconnect device, the disconnect device shall remain readily operable. Warning: the user shall not place this apparatus in the confined area during the operation so that the mains switch can be easily accessible. 1. Do not use this apparatus near water or in locations where condensation may occur. [. . . ] Use the LEFT/UP and RIGHT/ DOWN buttons or simply scroll the JOG control to view the level of dB SPL in real-time for the center frequency of all 31 bands. 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 PAA3's default screen. page 10 PAA3 User's Manual PHONIC CORPORATION 3. On the main RTA display, hold the ENTER button for approximately 2 seconds to activate the SPL screen. You can easily refresh the Max SPL value by holding both the left and right keys simultaneously for at least one second. RT60 (Reverb Time Analyzing) The RT60 function of the PAA3 is easy enough to understand: it is basically the time it takes for a signal to drop 60 dB. Getting the average of many different RT60 calculations from around a room allows users to get an idea as to how much absorption or reflection of audio the room provides. Depending on your needs, you may wish to have a high or low RT60 measurement. For example, for public speaking, an RT60 measurement of less than 1 second is preferable, as to have a clear, concise voice conveyed to the audience. With choirs or instrumental music, an RT60 measurement of greater than 1. 5 seconds may be appropriate. The PAA3 will wait for a signal greater than 30 dB over the background noise level (detected prior to the measurement). A little helpful hint: the louder the test signal, the greater accuracy of your RT60 calculation. Slowly move the master fader up, to a point where the audio level received by the PAA3 is greater than 30 dB. Quickly mute the system to get your RT60 reading as accurate as possible. After the measurement is taken, the RT60 measurement will appear onscreen. PHONIC CORPORATION PAA3 User's Manual page 11 Accumulation: AC 01 Users are able to accumulate various RT60 calculations by pressing enter while the "ACxx" (where xx equals the number of accumulated values) option is highlighted. When RT60 measurements are accumulated, the average of said memories is automatically taken and displayed onscreen. After 30 memories have been accumulated, users will be forced to store their data, or else lose it. Store: STO Storing the results of RT60 measurements is simple. When the store page comes up, choose one of the memory slots from 1 to 10, and select YES to store. The memory slot you selected will have a box surrounding the number now, as to indicate that a memory is stored in that particular slot. Selecting "A/C" will clear all memory slots. Recall: RCL RT60 measurements can be recalled at anytime by selecting the "RCL" option in the RT60 menu. Each memory location page displays only 4 memories at a time, however, therefore users must select NEXT to continue onto the next page of stored memories. Average: AVG To get the average of RT60 measurements that are stored in the PAA3, simply select AVG. Select from memories 1 to 10 (memory slots with saved data are indicated by a box surrounding the slot number), a dot will appear next to the number to show that a memory slot is selected. When all memories are selected, simply select AVG to determine the average, or ESC to escape. [. . . ] The PAA3 software will be installed automatically. The simple menu located below the FILE pull down menu at the top left hand side of main PAA3 program will allow users to access the PAA3's functions. This menu is basically identical to that of the PAA3 itself, so as long as you can navigate the PAA3 menu, you will be able to navigate this one. Display Type: Clicking on the SPL METER (or LEVEL METER) button to the right of the aforementioned menu will allow users to switch the on screen display type between that of the spectrum analysis and the meter display. Memories: Taking up most of the bottom half of the PAA3 program window is the memory section. [. . . ]
