These are generally used with third-party power amplifiers, taking their inputs from active crossovers earlier in the signal chain.

These three groups laid down the framework for all other subsequent power trios: extended improvisation, hyperamplification through walls of amplifiers and cabinets, and the use of effects ( such as delay, distortion, flangers, fuzz bass, wah pedals, etc.

These amplifiers usually have a sharp treble roll-off at 5 kHz to reduce the extreme high frequencies, and a bass roll-off at 60 – 100 Hz to reduce boominess.

These electric guitar amplifiers add an aggressive " drive ", intensity, and " edge " to the guitar sound with distortion effects, preamplification boost controls, and tone filters.

These amplifiers are designed to be used with acoustic instruments such as violin (" fiddle "), mandolin, and acoustic guitar, especially for the way these instruments are used in relatively quiet genres such as folk and bluegrass.

These amplifiers, such as the Fender " Tweed "- style amps, are often used by traditional rock, blues, and country musicians.

These amplifiers are almost always in class AB.

These amplifiers are designed to be used with acoustic guitars, especially for the way these instruments are used in relatively quiet genres such as folk and bluegrass.

These substances function as unspecific amplifiers that increase the cathexis ( energetic charge ) associated with the deep unconscious contents of the psyche and make them available for conscious processing.

These amplifiers have high input impedance, which means that the digital system will not need to supply a large current.

These devices are optimized as amplifiers as opposed to oscillators.

These structures operate as narrow linewidth ( tens of GHz ) amplifiers and may be implemented as amplifying filters.

These are frequently described as operational transconductance amplifiers ( OTAs ) and normally have an input to allow the transconductance to be controlled.

These technologies include data converters, amplifiers, radio frequency ( RF ) technologies, embedded processors or digital signal processing ( DSP ) ICs, micro-electromechanical systems ( MEMS ) and sensors, power management, and interface products.

These were basically copies or variations of Gibson and Fender amplifiers.

These cosmetic changes were followed by a new " tailless " Fender amp decal and a sparkling orange grillcloth on certain amplifiers in the mid-1970s.

These are driven by 23 LA8 amplifiers providing 165, 600 watts of available power at 4 ohms.

These amplifiers were first designed long before the development of solid-state electronic devices ; they are still in use by both audiophiles and musicians who consider them to sound better.

These amplifiers ( collectively the 5150 series ) and speaker cabinets were the result of a collaboration with Eddie Van Halen.

These included its established electronic components and kit lines ( thousands of people started with the " Fun Way " series and worked their way up to assembling Playmaster amplifiers and speakers ), Yaesu amateur radio ( the company had secured the exclusive dealership ) and Uniden-Bearcat scanners.

These amplifiers used a complex feed-forward servo system which resulted in very low 2nd order harmonic distortion.

These systems would typically require coaxial cable interconnection from a transmitter to the linear amplifiers.

These short, `` streamlined '' meetings usually are sponsored by local banks, Chambers of Commerce, trade associations, or other civic organizations.

These roads are largely of less than highway standards, and usually carry traffic which is related to use of the National Forests.

These needs usually concern the reduction of guilt and some relief of tension.

These free-standing statues were usually marble, but also the form rendered in limestone, bronze, ivory and terracotta.

These are usually feeding, breeding or sheltering sites.

These favours usually entail Poirot being supplied with cases that would interest him.

These states are labeled by a set of quantum numbers summarized in the term symbol and usually associated with particular electron configurations, i. e., by occupation schemes of atomic orbitals ( e. g., 1s < sup > 2 </ sup > 2s < sup > 2 </ sup > 2p < sup > 6 </ sup > for the ground state of neon -- term symbol: < sup > 1 </ sup > S < sub > 0 </ sub >).

These are collegiate foundations, which provide a home and an income for unmarried ladies, generally of noble birth, called canonesses ( Kanonissinen ) or more usually Stiftsdamen.

These individuals usually have no body weakness, because their brain injury is not near the parts of the brain that control movement.

These songs usually have a very punctuated rhythm precisely for this reason, along with a call-and-answer format.

These are posteriorly directed and vary in number ( usually one to three ).

These two values are often interpreted as binary digits and are usually denoted by the numerical digits 0 and 1.

These specialty and pay BBSes usually had something special to offer their users such as large file libraries, warez, pornography, chat rooms or Internet access.

; Presiding Bishop or President Bishop: These titles are often used for the head of a national Anglican church, but the title is not usually associated with a particular episcopal see like the title of a primate.

; Honorary Assistant bishop, Assisting Bishop, or Bishop Emeritus: These titles are usually applied to retired bishops who are given a general licence to minister as episcopal pastors under a diocesan's oversight.

These may take the form of temporary charter hire of service buses, or the temporary or permanent conversion and operation of buses, usually of second-hand buses.

These layers of laminations are usually of cellulose paper, cotton fabrics, synthetic yarn fabrics, glass fabrics or unwoven fabrics.

These events are usually separated by periods of " normal " mood ; but, in some individuals, depression and mania may rapidly alternate, which is known as rapid cycling.

These symptoms include delusions or, less commonly, hallucinations, usually unpleasant.

These regions are also usually considered to be the historical geographical origin of Bambara people, particularly Segou, Sikasso, after diverging from other Manding groups.

These polls have been quite influential, as they indicate which strips the readers like best, and strips that have performed poorly in these polls were usually dropped.

These are usually written, and pronounced “ n choose k ”.

These remunerations vary between corporations, but usually consist of a yearly or monthly salary, additional compensation for each meeting attended, stock options, and various other benefits.

These rock types are usually of varying resistance, so the coastline forms distinctive landforms, such as coves.

These usually are not high-value coins, but the interest is in collecting a large volume of them either for the sake of the challenge, as a store of value, or in the hope that the intrinsic metal value will increase.
