CHAPTER 5 SIM MEASUREMENT SYSTEM SIM is a measurement and instrumentation system including a selection of hardware and software options microphones and accessory cables SIM is optimized for making audio frequency measurements of an acoustical system with a resolution of up to 1 24 of an octave the high resolution enables you to apply precise electronic corrections to adjust system response using frequency and phase time domain information Source Independent Measurement Technique SIM implements the Meyer Sound source independent measurement technique a dual channel method that accommodates statistically unpredictable excitation signals Any excitation signal that encompasses the frequency range of interest even intermittently may be used to obtain highly accurate measurements of acoustical or electronic systems For example concert halls and loudspeaker systems may be characterized during a musical performance using the program as the test signal allowing you to E View measurement data as amplitude versus time impulse response or amplitude and phase versus frequency frequency response NW Utilize a single channel spectrum mode E View frequency domain data with a logarithmic frequency axis mM Determine and internally compensate for propagation delays using SIM Delay Finder function 12 Applications The main application of SIM is loudspeaker system testing and alignment This includes NW Measuring propa
3. If the voltage increases above the upper boundary of the range the power supply can be damaged NOTE It is recommended that the supply be operated in its rated voltage window at least a few volts away from the extreme points This ensures that AC voltage variations from the service entry or peak voltage drops due to cable runs do not cause the amplifier to cycle on and off or cause damage to the power supply CHAPTER 1 Current Requirements Each UPJ 1P requires approximately 3 A rms max at 115 V AC for proper operation This allows up to five UPJ 1Ps to be powered from one 15 A breaker at 115 V and up to 9 loudspeakers at 230 V The UPJ 1P presents a dynamic load to the AC mains which causes the amount of current to fluctuate between quiet and loud operating levels Since different cables and circuit breakers heat up at varying rates it is essential to understand the types of current ratings and how they cor respond to circuit breaker and cable specifications The maximum long term continuous current is the maxi mum rms current during a period of at least ten seconds It is used to calculate the temperature increase in cables in order to select a cable size and gauge that conforms to electrical code standards It is also used to select the rating for slow reacting thermal breakers The burst current is the maximum rms current during a period of approximately one second used to select the rating of most magn
