Top quality channel strip.
The Eighteen Xs MkII is a one channel transformer coupled Microphone Preamplifier, DI, Line Amplifier and Passive Pultec Equalizer. It's an Class A design based upon Lindell's Hybrid amplifiers.
The Equalizer is Lindell Audio's take on the magical classic Pultec design. It's got 15db boost of the creamiest high end you've ever heard and the most punchy low end heard the 21th Century.
Lindell has also incorporated their famous "Mix Knob" from the 17X compressor. This means that you can parallel equalize your line input. This gives you more flexibility and a way of creating new tones.
