Pa1250t, General description, Key features
General Description:
The Electro-Voice® PA1250T is from the PA series of
professional commercial audio amplifiers. The direct path
airflow design reduces the heat buildup significantly and
allows for more reliable operation in slim two rack space
chassis. The audio performance of the PA1250T is superior
and fulfills the requirements in many demanding long term
applications from sound reinforcement, paging or life safety
installations.
High performance torroidal power and output transformers
combine clean saturation free audio performance with cool
running operation. The PA1250T features many of the same
comprehensive protection circuits typical in EV amplifiers.
Complete protection is provided for high temperature, audio
limiters, power up delay and peak current limiters. In addition
to the rated output power, the PA1250T provides excellent
headroom for a wide dynamic range on music signals. The
onboard dynamic limiter ensures that the output clipping of
the PA1250T will not will not generate excessive distortion. A
detented and marked level control on the rear panel provides
hidden reliable level adjustments for the channel. Front panel
LED indicates signal present, 0 dB, and limit. Phoenix type
connectors for inputs and outputs provide easy rack wiring.
