Electrovoice pa-1250t Техническое Руководство

The PA series of compact commercial rack mount power amplifiers are

designed for demanding sound reinforcement, background music/paging

and public address system installations where long term reliability and flex-

ibility is the ticket. These units are exceptional values, loaded with features

and are easy to install in a variety of system designs. The models in the PA

series range from 160 to 450 watts of power per channel in a compact

2RU package. 

All models have a variety of features which enables them to be cus-

tomized to a wide range of demanding commercial sound and audio

reinforcement applications. The PA1250T, PA2250T and PA2400T all

provide 70/100V output capability using low distortion output trans-

formers for wide bandwidth and minimal saturation. 

The input connectors are a 3pin phoenix style which provide balanced audio.

The speaker outputs also feature convenient phoenix style quick disconnect

terminals to facilitate pre-wiring of the installation. Built in rack mount ears

and rear rack supports provide secure and convenient mounting.

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 for a wide dynamic range

on music signals. The onboard dynamic limiter protects the amplifier and speaker from dangerous transients.

All the PA amplifier models feature a low distortion amplifier design which can be bridged for more power flexibility

in multi channel models. The physical chassis of the PA series is also designed for reliability. Ample internal cooling

capacity ensures reliable operation. The PA series runs cool and stable with the direct flow thru chassis layout. The

multistage cooling fan runs exceptionally quiet in all modes.
