Tube-Tech LCA 2B 2-Channel Compressor and Limiter

Description:
The two-channel Tube-Tech LCA-2B offers all-tube compression with the added flexibility an independent compressor and limiter per channel. It's perfect for drum overheads, stereo room mics, stereo guitar, bus compression, and just about any other stereo source you have in mind. You also have the option of inputting two mono sources, compressing on one while limiting on the other. Tube-Tech LCA 2B Compressor/Limiter, First Take: All tube, 2-channel with independent compressor and limiter per channel 6 attack/release presets and manual control Multi-unit link modeIndependent Compressor/Limiter The rackmount 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 sidechain circuit). Output gain control is placed between the VCA and output stage. 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 sidechain circuit.Six Presets and Manual Control The stereo compressor has six attack/release presets as well as manual control. The limiter attack/release is fixed and equipped with an on/off switch. The LED display is fed from the control 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, which is only filtered.Link Mode The control signal from the compressor and limiter is combined and sent to the link switch and to the control amp, which feeds the VCA. The 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. A switch (Link 1, Link 2) on the front panel selects which compressors are interconnected, and on which bus they are connected. If you select Link 1 on both channels, they will perform the same gain reduction. With several LCA 2B compressors in a rack, you can select which ones will work together. For example, by selecting LCA 2B #1, Ch. 1 on link 1; LCA 2B #2, Ch. 2 on link 1, and LCA 2B #3, Ch. 1 on link 1, they are now interconnected and will all act with the same compression. By interconnecting them in this fashion the unit that performs the most compression controls the others. It is also possible to have all the interconnected compressors control each other simultaneously.About Tube-Tech For over twenty years, Tube Tech has been one of the most prominent names in all-tube signal processing equipment. You'll find their gear in the best recording and mastering studios around the world. The company's founder, John Petersen is an electrical engineer who was factory trained at Solid State Logic, EMT, Studer, Sony, Neumann, and NTP Electonik

这是款在每个通道上都配有独立压缩器和限制器的双通道器材。这款设备是全电子管构造(除了电源部分和侧链路部分)。 VCA ( 1 号三级真空管)位于输入变压器和输出极之间。 VCA 获得的声音讯号反馈到侧链路中。来自于压缩器和限制器的控制讯号结合到一起传输到链路开关和控制放大器中,然后再反馈到 VCA 中。这两个双向链路母线可以连接到控制板后的两个 1/4 英寸的立体声插孔。通道可以被一起连接到立体声器材上,还可以通过两个连接母线和一个标准立体声插头连接到其它的 LCA 2B 上。这款压缩器有六个 att/rel 预置和手动控制。限制器是固定的。 LED 显示从控制放大器反馈。限制器 LED 从限制器缓冲器反馈。声音路径从输入到输出都是完全对称的。输入和输出都有非固定的变压器。除了在输出端的阳极电压外,所有的 DC 电压都是稳定的
