What are fold back speakers?

What are fold back speakers? 

Foldback speakers / stage floor monitors or “wedges” are speakers that are placed on stage, pointing back at the performers.Aug 10, 2015

What is a fold back mix? 

A system for making one or more separate mixes audible to musicians while performing, recording and overdubbing. Also known as a Cue mix. May be auditioned via headphones, IEMs or wedge monitors (wedge-shaped loudspeakers placed on the floor).

What are stage monitor speakers used for? 

Stage monitors are the speakers placed on the stage that performers use to hear themselves and the rest of their band. Different venues and situations call for different monitoring setups.

What is amplifier foldback? 

Foldback (power supply design), a current-limiting device in power amplifiers. Foldback (sound engineering), a speaker used to direct sound to performers.

What are fold back speakers? – Related Questions

What do foldback monitors do?

A foldback monitor is a small LCD or LED screen generally placed off-stage or at the front of the stage which is used to communicate information to the speaker.

What is foldback protection?

The Fold-back Protection Circuit shown in the blue ellipse as “Current Limit” protects the LDO regulator from damage by overcurrent if the output pin (VOUT) and the ground pin (GND) are shorted. It consists of the overcurrent protection circuit and the short current protection circuit.

What are the advantages of fold back over simple current limiting?

“Foldback” current limiting reduces the short circuit current whilst still allowing full output current during normal regulator operation, thereby giving more efficient use of the pass element’s SOA. and so foldback ratios of greater than 2 or 3 are impractical for low-voltage regulators.

What is current limit foldback?

Q: What is current limit foldback? A: This is a current limiting technique to limit the peak power dissipation to prevent thermal destabilization or thermal runaway in the power transistor (which usually leads to the part destroying itself), to keep it in its SOA (Safe Operating Area).

What does CC and CV led mean?

CV indicates the power supply is operating in Constant Voltage mode. The supply operates in Constant Voltage mode if the load does not require more current than the channel current limit. CC indicates the power supply is operating in Constant Current mode.

Do LEDs need constant current?

Just because LEDs are constant current devices doesn’t mean that they require a constant current power supply. In some cases, constant voltage power supplies might be best. We compare constant current LED drivers and constant voltage LED drivers to help you pick the perfect LED power supply for your application.

How much current is needed to drive an LED?

Most common LED’s require a forward operating voltage of between approximately 1.2 to 3.6 volts with a forward current rating of about 10 to 30 mA, with 12 to 20 mA being the most common range.

What is meant by VCV in electrical engineering?

VCV. Linear voltage-controlled voltage source. Description. Equations. Variables.

What is CC in power supply?

How do I set the power supply to use in constant current mode (CC mode)? The constant current (CC) mode is a control that always provides a constant current even if the load condition changes.

What does VCB mean?

VCB stands for Vacuum Circuit Breaker. In vacuum circuit breakers, the vacuum is used as the arc quenching medium. Vacuum offers the highest insulating strength.

What is CV on DC power supply?

constant voltage mode
Voltage regulation is also known as constant voltage mode (CV). In CV mode, the DC output voltage of the power supply is held constant at its voltage setting, unless the output current or the output power reaches the current limit setting or the power limit.

Why does PSU switch from CV to CC?

The current limit value is the crossover point between CV and CC mode. Meaning, if a load connected to the power supply draws or needs to draw more current than the limit, the supply will automatically go into CC mode, giving the supply current control of the power output.

What is CC and CV charging?

constant-voltage (CV) charging. constant-current-constant-voltage (CC-CV) charging. multi-stage constant-current (MCC) charging. CC charging* is a simple method that uses a small constant current to charge the battery during the whole charging process. CC charging stops whena predefined value is reached.

What is CC CV welder?

Direct-current (DC) power supplies can be constant-voltage (CV) or constant-current (CC). CV equipment, typically used for semiautomatic and wire-fed processes like gas metal arc welding (GMAW) or flux-cored arc welding (FCAW), provides a consistent preset voltage.

What is a Drooper welding?

As can be seen in Figure 20, the curve of a constant current machine drops down- ward rather sharply and for this reason, this type of machine is often called a “drooper.” 1.9.1.1 In welding with coated electrodes, the output current or amperage is set by the operator while the voltage is designed into the unit.

Can a welder be used as a power supply?

So, it is possible to make a power supply from your welder.

What’s the difference between arc welding?

The result is that TIG welding tends to be highly controllable and produces a stable electric arc and a clean, precise, and strong weld. In contrast, in arc or stick welding, the electrode is consumable. Unlike in TIG welding, the electrode acts as the filler metal rod and melts to form part of the weld joint itself.
