A very compact 4 channel amplifier that can deliver 150 watts per channel but only occupies one 1U of rack space. Low heat from the class D design means there are no noisy fans, so this is a perfect design for environments with low ambient noise. The JB system AMP1504 can be used as a 4 channel amplifier delivering 150 watts at 4 ohms or it can be bridged on both channels to deliver 300 watts at 8 ohms. There is also the option to bridge one channel whilst the other stays in stereo. A choice of XLR or jacks are available for input connections with the outputs being speakon or binding posts.
