Once in a call the audio and tone levels superimposed on the DC voltage are expressed as dBm in 600 ohms, although the line impedances are permitted to be some way off 600 ohms (as per SIN351) -9 dBm (275 mV RMS) [0 dBm = 1 mW ( 0.775V RMS) in 600 ohms.
Its impedance at audio frequencies, and especially at the more restricted telephone band frequencies, is far from constant. It is possible to manufacture this kind of cable to have a 600 Ω characteristic impedance but it will only be this value at one specific frequency. This might be quoted as a nominal 600 Ω impedance at 800 Hz or 1 kHz.
Line outputs usually present a source impedance of from 100 to 600 ohms. The voltage can reach 2 volts peak-to-peak with levels referenced to −10 dBV (300 mV) at 10 kΩ . The frequency response of most modern equipment is advertised as at least 20 Hz to 20 kHz, which corresponds to the range of human hearing .
The Ampeg SVT is a bass guitar amplifier designed by Bill Hughes and Roger Cox for Ampeg and introduced in 1969. The SVT is a stand-alone amplifier or "head" as opposed to a "combo" unit comprising amp and speaker(s) in one cabinet, and was capable of 300 watts output at a time when most amplifiers could not exceed 100 watts output, making the SVT an important amp for bands playing music ...
Jerrold Electronics was an American provider of cable television equipment, including subscriber converter boxes, distribution network equipment (amplifiers, multitap outlets), and headend equipment in the United States.
To match the impedances, both cables must be connected to a matching transformer with a turns ratio of 2:1. In this example, the 300-ohm line is connected to the transformer side with more turns; the 75-ohm cable is connected to the transformer side with fewer turns. The formula for calculating the transformer turns ratio for this example is:
To accommodate these instruments, active direct boxes were designed containing powered electronic circuitry which increased the input impedance to above 1,000,000 ohms. In 1975, a 48-volt phantom powered active direct box was designed for Leon Russell 's recording studio, its circuitry published in the April 1975 edition of dB , the sound ...
Pedestals are used for CATV (known as a cable box in such a situation), telephone, passive optical networks, and other telecommunications systems. A pedestal is generally a sheet metal or plastic housing that encloses a passive termination block. The pedestal is usually about 3 feet high and has a diameter of less than one foot, with a circular ...
