    The BTUBE-TECH LCA 2BB 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 buses are accessible at two 14" 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 buses and a standard stereo jackjack cord.

    The compressor has six attrel presets as well as manual control. The limiter attrel 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, except the anode voltage for the output stage.
