[. . . ] There are common features and performance specifications with the major theme of the product being superior reliability with a "value" price tag. The product line also gives as an added bonus key enhanced features often provided only on more expensive products including a comprehensive power protection system and advanced cooling technology. The PA Series Product Position is. . . . . [. . . ] Its' ample internal cooling capacity ensures reliable operation. The PA series runs cool and stable with the direct flow thru chassis layout. The infinitely variable cooling fans run exceptionally quiet in all modes. Extra heavy gauge chassis sheet metal with built in front panel rack "ears" and full size rear rack supports allow for a solid and secure installation. The Performance ­ Clean Reliable Flexible Power All the PA amplifier models feature a low distortion amplifier design that can be bridged for more power flexibility in multi channel models. With an extremely low 0. 1% THD and wide 10Hz to 50kHz power bandwidth, these amplifiers deliver clean colorless sound. The superior output transformer in the "T" models effectively resists saturation down to 20Hz and the switch-able hi-pass filter further prevents low frequency distortion in critical applications. The Reliability - A Complete Protection Package A comprehensive 4-way protection package in every PA series amplifier helps protect the amplifier and speaker for reliable long term performance. The package provides complete protection for excessive temperature, audio limiters, power up delay and peak current limiters. All PA series models provide excellent headroom of up to 20% for a wide dynamic range on music signals. The onboard dynamic limiter ensures that driving the amplifier into clipping on the PA1250T , 2250T and 2400T will not generate excessive distortion. All the "T" models feature torridal output transformers for exceptional speaker isolation. This virtually eliminates the possibility of speaker damage through shorts or other anomalies, which are possible in direct drive 70V/100V designs. What's the Competition? The key competitors for this product include Crest, Bogen, along with one series of QSC and Crown to a lesser extent. All of these amplifiers are good in their own right but none of these manufacturers can offer the comprehensive solution that EV can.
