The Universal Audio LA-610 MKII is a tube-based microphone preamp and optical compressor combination unit that is designed to provide top-quality sound and flexible options for recording studios. It is based on the classic LA-2A compressor and the 610 tube preamp, which are both known for their warm, vintage sound.

The LA-610 MKII offers a range of features that make it a standout choice for professional engineers. The tube-based preamp section offers a range of controls for shaping the sound of the input signal. There is a mic/line switch for selecting the input source, a high-pass filter for cutting out low frequencies, and variable input impedance for tailoring the sound to different types of microphones. There is also a -15dB pad for handling high-level sources.

The preamp section is where the tube magic happens. The 610 preamp is known for its warm and rich tone, and the LA-610 MKII delivers on that promise. The preamp section is designed to give a subtle but noticeable character to the sound, adding warmth and depth without overwhelming the original signal.

The LA-610 MKII’s optical compressor section is based on the LA-2A compressor, which is known for its gentle and musical compression. The compressor offers a range of controls, including threshold, gain reduction, and makeup gain. There is also a switch for selecting between fast and slow release times.

One of the benefits of the LA-610 MKII is the combination of the tube preamp and optical compressor. The tube preamp can be used to add warmth and character to the sound, while the compressor can be used to tame the dynamics of the signal and add some gentle compression. The combination of these two sections can create a sound that is both vintage and modern at the same time.
