Double The Desire!

The TUBE-TECH LCA 2B is a two-channel unit with an independent compressor and limiter per channel. The unit is all tube based (except for the power supply and side chain circuit). The VCA (1 dual triode) is placed between the input transformer and the output stage (2 dual triodes).

The audio signal is picked up after the VCA and fed to the side chain circuit. The control signal from the compressor and from the limiter is combined and sent to the link switch and to the control amp, which feeds the VCA. The two bi-directional link busses are accessible at two 1/4" stereo jack sockets on the rear panel. The channels can be linked together for stereo applications and also linked to other LCA 2B's via the two link busses and a standard stereo jack/jack cord.

The compressor has six att/rel presets as well as manual control. The limiter att/rel is fixed. The LED display is fed from the con-trol amp. The limiter LED is fed from the limiter buffer.The audio path is fully symmetrical from input to output. Input and output have fully floating transformers. All DC voltages are stabilized, ex-cept the anode voltage for the output stage.

Wonderful, Versatile Compressor

This is a great piece for tracking, especially while recording overdubs, as you can use it again and again on everything you are doing from acoustic guitars to vocals. THEN, when you are ready to mix, put this baby on your 2-mix stereo buss. Heaven. You need one of these.

TUBE TECH LCA2B COMPRESSOR/LIMITER

I recently purchased the LCA2B...from Sweetwater. Prior to the purchase I spoke with my sales rep., Rob Russell. I've been dealing with Rob for some time and he knows my studio setup. I asked his advice on purchasing a comp./limiter that would be compatible ,in quality, to my current setup. He recommended the LCA2B. The choice could not have been better. the tube tech LCA2B is a great piece of gear. It places the track right in the mix. Its' clarity/transparency and "gain" is second to none. Yes, I've used other compressors. The LCA2B stands second to none.
