The problem of setting a resistance power amplifier with different power of ceiling speaker and column speaker
Problem Description: power amplifier and a speaker is connected problems, a common fixed resistance amplifier are connected to the two 6W ceiling speakers, a 30W column loudspeaker. Now the question is Ceiling
Speaker's sound is OK, but the sound of column speaker too small? What can we solve the problem?
First of all,to confirm if the ceiling speakers and the column speaker is voltage speakers, if the answer is yes.
Then try changing terminal of the column speaker! The power amplifier output power is not the same as the
voltage is not the same, is not a simple split the problem of the transformer in parallel! If it is a certain
impedance to be reliable, do not casually parallel, what is the general resistance to the power amplifier? Fixed
resistance also has output high voltage!
Other way :
1.Another channel work with column speaker, independently adjust the volume.
2.Add a 10W volume potentiometer to the two ceiling speakers, individually controlled ceiling speakers, adjust the volume of power amplifier, outdoor column speaker volume moderate, followed by volume controller regulating ceiling speakers.
3.The constant resistance power amplifier is low pressure, the suction top horn and the sound column is the
constant pressure 100V-120V, the simple use of the output transformer, set the resistance to set the pressure, but with low reliability .
4.Take out the the transformer n column speaker.
