High input

What is a high level input? High level inputs means that you are using the speaker wire leads off of the back of the radio instead of using the RCA connections. You can take the speaker wire connections and use them to send the input signal to the amplifier.

What is high and low input?

The "Hi" input attenuates the input signal, usually by between 10-15dB (about half to a third the original volume). The "Low" input will not do this. Different guitars and basses produce widely varying signal levels.

Is high level or low level input better?

Using the High Level input is always the best option. Using the High Level Input, instead of the Low Level Input, and connecting to the speaker output terminals of your amplifier is one of the unique secrets of REL's success.

What is the meaning of high input impedance?

In electronics, high impedance means that a point in a circuit (a node) allows a relatively small amount of current through, per unit of applied voltage at that point.

What is low level input?

Low-Level (Line Level) Inputs: Line level inputs, also known as RCA inputs or low-level inputs, use RCA interconnect cables to link the amplifier with the source unit. Most aftermarket radios have multiple pairs of RCA outputs that can connect to multiple amplifiers.

What causes high input impedance?

Why does an op amp have high input impedance? Op amps need high input impedance because they are voltage-gain devices. In order for voltage to drop across the input, the impedance has to be very high, as ohm's law states, V=IR. It's also important to prevent the loading effect.

What is high level output?

Standard high-level outputs take the signal from your sub to the speakers. On the other hand, high-level inputs take the signal from your receiver/amp, through the speaker-level connection, and into the subwoofer. These inputs also come in color-coded pairs.

What is high level input on subwoofer?

So, you would usually use the high-level connection on your subwoofer if: You are using a stereo amplifier without a dedicated subwoofer or stereo pre-outs. You are using an AV receiver or stereo amplifier with a subwoofer pre-out or stereo pre-outs – but prefer the sound of music via the high-level connection.

Is it better to use high level inputs on amp?

High Level or Speaker Level Inputs Nowadays, most amplifiers accept high level inputs up to 10 volts and you can connect speaker wire via the radio's speaker wire connections straight to the amplifier which means an easier installation and even better sound.

What phase should a subwoofer be set to?

Typically, though, phase is left at 0° for most applications. While seated in your listening sweet spot, play music with bass content that is familiar to you and then have someone switch the 0/180 phase switch on the sub to 180-degrees. This will let you determine if the bass sounds louder in your seating position.

Can I use both high and low level outputs?

No, it is not recommended connecting the High Level and the Low Level simultaneously. These two inputs are run on the same circuit internally on the REL and will result in far too much gain.

What is input sensitivity on an amp?

Input sensitivity is the maximum voltage strength of an input signal that an amplifier can handle and still produce unclipped full output. This is important to understand because not all audio signals have the same voltage.

What does low input impedance mean?

High impedance means the circuit draws or gives little power to the signal. low impedance means the circuit draws or gives more power to the signal.

What is high or low impedance?

Speakers are designated as either low- or high-impedance types. Low impedance is in a range of approximately 4 to 16 ohms. Low impedance speakers are used in various sound systems such as household stereo system and car audio system. High impedance usually means an impedance of several-hundred ohms to several-k ohms.

Is high impedance good or bad?

In general: High impedance sources provide high voltage but low current. Equal impedance between source and headphones is good for portable power requirements, but not necessarily for sound quality.

What is a line-level input?

What is line level? A line-level signal is approximately one volt, or about 1,000 times as strong as a mic-level signal, so the two do not ordinarily use the same input. This signal travels from your pre-amp to the amplifier that powers your speakers.

Why do subwoofers have 2 inputs?

Dual input allows the subwoofer an extra sensitivity adjustment. Normally, it would be enough to use a mono LFE subwoofer signal from its processor. If you have a processor with very low output so you can use a Y-splitter. By using both inputs with the same mono signal doubles the subwoofer sensitivity.

What does high output mean on amp?

A high-output pickup sends a stronger signal to an amp, for a given amount of string movement/mass, compared to a lower-output pickup. This is a term that means different things depending on your perspective — describing a pickup as “high output” is relative, depending on what you are comparing or using as a reference.

Why do we want high input resistance?

The reason for making high input impedance is that “The circuit can be driven by any source” to avoid any loading effect. This ensures maximum current is provided by source. The reason to ensure low output impedance is that “The circuit can drive any load”, even the load impedance is small in magnitude.

How do you get high input impedance?

The emitter-follower input impedance is β(re + RE), where RE is a discrete emitter resistor. At low input currents, RE is very high and the input impedance is very high. If a higher input impedance is required, the op amp uses a Darlington circuit that has an input impedance of β2(re + RE).
