The connectors on the rear panel are clearly labeled. The two connectors on the left side are the stereo left and right outputs. |

Used to play LP, 45 and 78 RPM records. The stereo output connectors are on the rear side of the base. |

Examples of amplifiers:

front and rear views The rear panel connectors are labeled, more on this as we go along. |

front and rear views This amplifier powers the loudspeakers through speaker cables (an example is shown below. Why can't we just connect a source to the power amplifier? Why do we need a preamplifier? CD players seldom have a volume control and often the power amplifier doesn't have one either so we need the volume control in the preamplifier. Also, a turntable does not have enough output for the power amp so we need a preamp to boost the signal. The connectors are clearly labeled on the rear panel. |

a pair of 7 inch aluminum cone woofers for the bass tones and a ribbon tweeter for the treble tones. This is a "sealed box" design and "ported box" designs are also available. Ported boxes CAN have a better bass response, but their placement in the room is more critical (in my opinion). |

connectors. Most of the audio equipment built in the US uses "so-called" RCA connectors for connecting the sources to the preamp and the preamp to the power amplifier. These cables come in standard lengths from 20 inches to 15 feet. |

|
These common connectors are called "banana" plugs with a 3/4 inch spacing in the US (but not in Europe). Some standard lengths are available, but usually the cables are custom made to fit your needs. The cables to the left and right 'speakers should be about the same length, based on the longer one. TDL® buys speaker cable in bulk and quantities of connectors so we can easily build cables to whatever length you need. |
