This professional grade amplifier features a dB signal-to-noise ratio with 0. The XPA is one quarter the size of comparable amplifiers, conserving rack space and weighing only 2. The Extron exclusive, high efficiency design generates very little heat and allows the amplifier to be convection cooled. With an auto power-down feature that automatically places the amplifier into standby after 25 minutes of inactivity, it consumes just 10 watts when idle and less than 1 watt in standby mode. The XPA is housed in a compact 1U, half rack width enclosure.
