What does the channels mean on an amp? a channel is a output from the amp to the speakers or subs. if you have a 2 channel amp there is 2 outputs on the amp if you have a 4 channel amp there are 4 outputs this goes for all the amps whither it is a 1 channel,2channel 4channel or 5 channel. channel= output.

Airband As of 2012, most countries divide the upper 19 MHz into 760 channels for amplitude modulation voice transmissions, on frequencies from 118–136.975 MHz, in steps of 25 kHz. In Europe, it is becoming common to further divide those channels into three (8.33 kHz channel spacing), potentially permitting 2,280 channels.

Amplifier An amplifier, electronic amplifier or (informally) amp is an electronic device that can increase the power of a signal. An amplifier functions by taking power from a power supply and controlling the output to match the input signal shape but with a larger amplitude.

Many women use an OB/GYN as their main doctor. Should they? There’s nothing inherently wrong with going to an obstetrician/gynecologist for routine preventive visits — these doctors are trained to provide such services — but a recent study suggests that women who choose an OB/GYN as their primary physician may miss out on more-comprehensive care.

downstream 3) In CATV, a downstream channel is one used to transmit signals from the headend to the user. An upstream channel is one in another frequency band that is used to send signals from the user back to the headend.

what does audio channel really mean? Re: what does audio channel really mean? A channel is something through which data(in the form of electro magnetic data or electric current or other wave) signal travels from source to destination. Physically a audio channel can be said as a simple wire through which electrical signal is propagated. This signal is analog in nature and contain many frequencies. In the case of sterio audio we have two channels. A sterio audio is recorded by using two different micro phones. So we have to set of data.

If a modem/router has 16 downstream and 4 upstream channels, what does this mean? The DOCSIS standard describes how to send data over cable TV systems. A downstream cable channel sends data from the cable company headend to you. For historical reasons related to analog television, a channel is 6 MHz wide (or 8 MHz wide in Europe). Normally, this carries a video signal. For data channels, it carries data.

- A signal amplifier is used in cases where one of your broadcast towers is located at a significantly further distance than the others, or you are having trouble getting reliable reception from one or two channels due to foliage, a mountain range, or splitting signals inside the home between two or more television sets.

- This is often viewed as less important in guitar amps. Feedback reduces the distortion generated by the three stages. With tubes, an amplifier without feedback can be made and there are quite a few popular amps using this design.

Pathos Ethos review After switch-on, the amplifier defaults to Input One (XLR) and the volume control is set at – 52dB. If you switch the amplifier off from the front panel, your previous volume and input settings are remembered. However, if you switch off from the wall socket, or disconnect the mains supply, your settings are lost.

Operational amplifier The amplifier's differential inputs consist of a non-inverting input (+) with voltage V+ and an inverting input (–) with voltage V−; ideally the op-amp amplifies only the difference in voltage between the two, which is called the differential input voltage.

Operational amplifier An operational amplifier (often op-amp or opamp) is a DC-coupled high-gain electronic voltage amplifier with a differential input and, usually, a single-ended output.

Operational amplifier applications Input bias currents and input offset[edit] Practical operational amplifiers draw a small current from each of their inputs due to bias requirements (in the case of bipolar junction transistor-based inputs) or leakage (in the case of MOSFET-based inputs).

Car Amplifier Tuning and Features Since “mono-block” amplifiers have only one channel used to power subwoofers, there is only one LEVEL or GAIN dial to set. For multi-channel amplifiers designed to power one or more pair of left and right speakers, there are usually two or more LEVEL or GAIN settings.

Amplifier An amplifier, electronic amplifier or (informally) amp is an electronic device that can increase the power of a signal (a time-varying voltage or current). An amplifier uses electric power from a power supply to increase the amplitude of a signal.

Differential amplifier A differential amplifier is the combination of inverting and non inverting amplifier. A differential amplifier is a type of electronic amplifier that amplifies the difference between two input voltages but suppresses any voltage common to the two inputs.

Amplifiers The purpose of a current amplifier is to make the amplitude of the output current waveform greater than that of the input current waveform (although the amplitude of the output voltage may be greater or smaller than that of the input voltage, this change is less important for the amplifier´s designed purpose).

Car amplifier buying guide A 2-channel amplifier will be the practical solution when you only need to power a single pair of speakers. But if you like rear-fill sound in your car and want to retain front-to-rear fade control, get a 4-channel amp — one channel for each speaker.ryan, When you plan a system, you need to use the RMS wattage ratings only, never peak ratings. It does seem like a 3000-watt amp should overpower two 1000-watts subs, but the first number is a peak rating and the second is an RMS spec.

Treacher Collins syndrome Mutations in the TCOF1, POLR1C, or POLR1D gene can cause Treacher Collins syndrome. TCOF1 gene mutations are the most common cause of the disorder, accounting for 81 to 93 percent of all cases. POLR1C and POLR1D gene mutations cause an additional 2 percent of cases.
