Part 3
• Amplifiers
• Clipping
• Bridging
• Slew Rate
• Matching power amplifiers to loudspeakers
, Loading: connecting a speaker “load” to an amp.
Most speakers have an impedance of 8Ω
Connecting two 8Ω speakers linked together (parallel
connection) yields a 4Ω load.
Amplifiers need a minimum load in order to work correctly.
If we connect too many speakers, the load becomes too
low and we risk damaging the amplifier.
Most amplifiers have a minimum of 2Ω or 4Ω.
, In order to calculate speaker loads, we can use the
following parallel impedance formula:
Z xZ
ZT = Z 1 + Z2
1 2 Short-cut:
8Ω 8Ω (only works with
8x8 64 equal speakers)
8+8 = 16 = 4Ω
load of each speaker
÷
Number of speakers
