To test a record player with a power amplifier: 1 . Connect the speaker to the power amplifier output. 2. Connect the record player pickup output to the power amplifier input. 3. Keep the power amplifier volume setting low. 4. Turn on the power AUDIO POWER AMPLIFIER 18 V 0.1 uP Z}, Reprinted by permission of Texas Instruments.

The.makers describe this as a lowpower amplifier capable of generating a few hundred milliwatts in a 4R0 to 16R speaker load, but it can in fact generate as much as 2W in an 8R0 load. It can use supplies in the 3–16V Antenna Speaker Figure 2 16 Block diagram of a typical AM radio receiver The antenna picks up signals from several stations and these are fed into the Radio Frequency (RF) Amplifier which improves the SignaltoNoise (S/N) ratio. The RF Here, dc current is fed to pin 9 via the speaker and R1, and the 'low' end of the speaker is ac driven by the amplifier's output, thus bootstrapping R1 and giving it a high ac impedance value. This circuit thus gives a performance similar to that of a 9V supply and
