The EPQ Series power amplifiers pack the power of Accelerated Transient Response (ATR) technology into an exceptionally lightweight package. Ample power and high-tech efficiency combine to give you a feather-light supercharged workhorse that will keep your rig kicking for years to come.
Behringer EPQ304 Amplifier , 4x 75 Watt / 4 OhmI own 2 of these, used for the hf section of a 44 pieces line-array.
For my needs its perfect.
Only 1 RU space, lighweight but strong alluminium chassis.
Sound is crispy enough for PA applications, maybe not suitable for high-grade HIFI but.. its a PA amp.
I wouldnt suggest it for full-range PA amplification, caused by the low power rating. For my needs of 60W rms per channel on 4 Ohm its the best price-performance amplifier i could want.. and find on the market.
