Power Solutions Reduce Amplifier Hiss and Ticks

Today's high performance amplifiers, CD players and other sound and vision

sources demand mains of the highest quality to enable them to provide their

best performance. With mains borne interference from other domestic devices

frequently polluting the power supplied to hi fi and AV amplifiers, it's not

surprising that equipment frequently fails to match our expectations in

sound quality. Moreover, externally generated interference from industrial

sources and even lightning strikes can cause potential damage to costly

equipment, as well as severely compromising sound reproduction.

Advance Electronics, the UK's premier supplier of power quality management

solutions, has revealed its brand new range of noise filters, power

conditioners and voltage surge suppression devices, specifically optimised

for the hi fi and home cinema markets. Each item has been designed to

eliminate the problems that can arise when sensitive equipment is connected

to a typical mains supply. In particular, dirty mains can cause amplifiers

to hiss, while unwanted transients in the power supply can cause the ticking

sounds that are sometimes heard through loudspeakers.

To combat these frustrating and potentially damaging forms of interference,

Advance Electronics' portfolio of power quality management solutions

includes the AIT 1000 noise filter, a maintenance free Galvanic isolation

ultra low impedance transformer. This unit offers superior electrical noise

and transient attenuation compared to the conventional filter plugs,

filtered power distribution strips and electronic conditioners that are

often sold as suitable solutions to hi fi related problems.

Also available is the AGT power conditioner range, which incorporates a

constant voltage transformer to provide Galvanic isolation and high common

and normal mode noise attenuation. These units automatically generate a

stable output voltage, as well as neutralising and absorbing damaging

spikes, surges and electrical noise. Advance Electronics offers several

specific models with a wide range of power ratings, suitable for any

combination of pre/power amplifier and CD or AV source.

For hi fi users concerned about the damage that voltage surges and spikes

can cause to their amplifiers and sound sources, Advance Electronics also

offers a full range of passive transient voltage surge suppression (TVSS)

devices. Each of these units features innovative matrix technology that

absorbs harmful transients without causing damage to valuable equipment.

Additionally, these surge suppressors can successfully eliminate the

annoying ticks that are sometimes audible when an amplifier is idling

without being fed a signal.

Moreover, for any enthusiasts that might be running either valve pre or

power amplifiers, or even tube-based CD stages, transient surges have been

proven to severely reduce the operational life of such equipment. And, with

many valve components now becoming irreplaceable, the voltage surge

suppression characteristics of noise filters, power conditioners and TVSS

devices should be considered essential for any users wishing to protect

expensive and rare equipment.

According to Managing Director Nathan Briggs, the latest Advance Electronics

range of hi fi and AV optimised power solutions represents the natural

choice for virtually any sound and vision enthusiast. 'Expensive and

sensitive amplifiers, output stages and sources need a stable power source

that can eliminate noise and surges. Our new range gives audiophiles a wide

choice of solutions to the age old problems of hiss and ticks arising from

the mains, as well as offering safety and protection for valuable

components,' he said.
