If you want to make a precise delay time adjustment connect the PCR2213 with dual channel oscilloscope with PCR2213 input signal measured by one oscilloscope channel and LF output to the other channel Send the sine wave into PCR2213 and adjust the delay time until the horizontal time offset equal to your design 5 5 LIMITER SETTING 1 To properly set the limiter threshold You need to find out the capacity of the speaker and associated amplifier Because the threshold is global setting we shall make use of the level control on the PCR2213 as well as those on the power amplifiers so that it works with all bands 2 Disconnect one set of the speakers and hook up dummy loads same value as the speaker loading to the amplifiers You can connect only one output of the amplifier if you have multiple for the same band and turn them off without removing the speaker connection 21 Turn the threshold all the and switch on limiters Let s start from the HF output Turn up the mixer master level until the HF power channel reached the threshold power vou want to limit o0 t Turn down the threshold until the HF limiter indicator lighted Now you have done the first limiter point There are 3 more or 2 more to go 7 Ifyou keep all the output levels on PCR2213 at 0 12 o clock the LF output of the same channel prob ably reached limitng at the same time But the power amplifier level maybe higher or lower than the power you wish to

30. rmally for lower level signal the signal conductor is shielded by the ground conductor What is a balanced system Balanced system transmits the signal via 2 conductors plus one ground shielding conductor The 2 signal conductors carry the same signal but out of phase For the balanced input stage the amplifier will boost the difference of the 2 signal conductors and remove the identical part known as common mode signal of the 2 signal conductors Because of the real signal is carried by the 2 conductors out of phase so it is perfectly carry to the input At the same time the interference occurs during transmission will be identical part common mode because the signal conductors are run together there is no chance they can be different and all the interference will be removed by the balanced input amplifier 11 e difference in between 2 operations Because the common mode interference immunitv of balanced svstem and at the same time the ground conductor doesn t need to carrv anv electrical current so that it means the ground of the 2 connected units has identical ground level which is vital to interference free svstem Let s look back to unbalanced svstem the signal electrical current is from signal conductor to ground conductor and that means the ground level of 2 connected units are not identical This means the svstem is much more easier to be interfered with noise Running long cables is easv for balanced svstem but dif
