"What a refreshingly honest blog about listening to music through hi-fi. So happy to see views based upon the enjoyment of music rather than so-called sound 'quality'." - Peter Comeau, Director of Acoustic Design at Mission / Wharfedale

Inside an Active Linn AV5125

Some photos of the inside of the AV5125 five channel amplifier with 2 x stereo active cards installed - 1 x stereo treble and 1 x stereo bass (in this case, the cards are for Keilidh speakers, but the cards are in the same format for all AV5125s. There is room for one more mono card for the 5th channel, but its not installed in this case.

AV5125 Rear Panel - showing 5 channels of inputs (1 input and output per channel to facilitate bi-amping or active) and speaker terminals (2 speaker outputs per channel to ease bi-wiring),  4 slots in the upper right hand half would have tabs sticking out indicating the type of card installed, should active cards be in place inside the amp.
