Selling a tested and working 2U rack mount four channel audio amplifier formerly used in a church organ system.
The front is marked "4 x 75 Watts into 8 ohms, 4 x 120 Watts into 4 ohms, 240W into 8 ohms bridged" There are two buttons that will turn on/off the green LED lights below them marked "4 CHAN and MUTED. Below that is a diagram marked 1, 2, 3, 4, BRIDGED. I checked with Input A which is an 8 pin female jack- the male plug is included attached to a cable with four RCA jacks carefully spliced on and covered with heat shrink tubing.
All the channels checked individually and all work great with crisp, clean sound quality and no hum or distortion when connected to my Kenwood preamplifier. Very powerful. I am not sure how exactly to connect for bridging or exactly how the two front buttons are supposed to work but if you need to use in Bridged mode you should be able to figure it out with some trial and error. The last photo shows how the amps connected to the organ- only the A input was used for each one.
The amp was made in 1999 and the components are high quality with a large round power transformer. I think they were made in the UK.
