FOLLOW INSTRUCTIONS - Follow all operating and use instructions. [. . . ] Play the 1kHz Sine Wave, hard assign it to the left channel only, and adjust the output fader so the output meter reads -20dBFS. If you are using an analog console, set the output level to 0 VU. Then hard pan the signal to the right channel output and repeat for the right channel. Once calibrated do not move the output faders. Mute everything and make sure the 1kHz tone is OFF . Now that the system has been electrically calibrated turn ON your 2. 1 System (SUB 15 Universal + monitors). Feed 40-80Hz pink noise signal to the left channel only. Adjust the subwoofer level control until the subwoofer reads 85dBC (slow) at the mix position. The meter will bounce around a little, so you will need to do a mental average (I tend to filter out the peaks in my mind, so I don't set the sub too hot). The right channel should measure about the same and no additional adjustments need to be made. You can play the full-bandwidth pink noise, assigning it to the left and then the right channel (not at the same time). It may be a little higher, because below 30Hz the room may have a little extra gain. No adjustments should be made with Full Bandwidth pink noise, unless you have an RTA (real time analyzer). Step 7 Step 8 You are finished and the calibration process has been completed ­ enjoy! A note about the LF EXTENSION and PHASE switches: One of the SUB 15 Universal's unique features is a switchable low frequency response characteristic, of either 30Hz to 200Hz +/-3dB or, in "extended LF mode", 20Hz to 200Hz +/-3dB (anechoic), marked 30Hz and 20Hz respectively. extended The mode is ideal for large rooms that don't exhibit the room gain phenomenon of smaller sealed spaces. The only way to be absolutely sure of which setting is appropriate for your studio is to use an acoustic analyzer. Using the 20Hz in a sealed space, such as a small to medium size studio, can result in a rising LF response characteristic below 30Hz. Step 3 Step 4 The PHASE setting on the SUB 15 Universal should typically be set to 0, especially when the SUB 15 Universal is used with Blue Sky SATs. However, there may be times, depending on the speakers used with the SUB 15 Universal or because of certain acoustic conditions, that the phase setting needs to be proper between SAT and SUB. The only way set to 180, so as to get summation to be absolutely sure which setting is appropriate for your studio is to use an acoustic analyzer. Page 7 7.
