Another British classic. A very good little pre-amp originally designed to accompany the 100 series mono-block power amps (also a tuner and standalone Moving Coil pre-amp). This is a very small unit but quite long as are the mono blocks. The simplicity may be it's secret because the sound quality should not be that good...except that it's Meridian and I have never come across a bad piece of Meridian equipment, lovely build quality and great sounding all of it. I wish I had the mono blocks to with it. The seven pin DIN out put can be used with a 5 pin lead the two un-used have +/- 15 volts DC presumably to run some other unit. One side of the DIN has left and right output conventional the other side has balanced outputs.
