The CP5176 is a FET compressor based on the design that was originally used in the 1176 compressor, which has been adapted to the '500' format of API*.
This compressor became extremely popular because of some specific characteristics such as its ultra-fast attack time, as well as its unique sound, due to the FET transistor, the class A and the transformers.
It is typically used for compressing snare, vocals, guitars or drum bus in stereo.
The CP5176 adds a few features to the original 1176 such as a new ratio of 2, a high-pass filter in the side chain and a variation in the FET gain reduction circuit that produces more distortion.
1 InputPotentiometer that sets the signal level before compression. It defines the compression threshold.
2 Out Potentiometer that set the signal level after compression (make up gain).
3 Ratio Rotary switch that sets the compression ratio from 2 to 20. Ratio 2, allowing more subtle compressions, has been added to the original circuit. The SLAM mode is the "all buttons pressed" on the 1176.
4 Attck Potentiometer that sets the attack time: The delay before the compressor starts reducing gain.
5 Rel Potentiometer that sets the release time: Time that the compressor takes before returning to the "no gain reduction" state.
6 Gr High resolution gain reduction display: 16 LED's from -1dB to -22dB.
7 HPF Inserts a 80 Hz high-pass filter in the sidechain. Produces a Fat sound and eliminates bass driven pumping.
8 Dist Modifies the signal balance on the FET, adding second harmonic distortion. Close to the Rev A version of 1176.
9 Link Connects two compressors in stereo mode.
10 LED that shows the bypass status.
11 Off Compressor bypass button (hardware by relay).
1 Original Cinemag input transformer.
2 All discrete audio path with high grade components.
3 Discrete Op-Amp output circuit, pin compatible with API* 2520.
4 Original Cinemag output transformer.
5 Easy setup of 3 trimmers with a voltmeter, without iteration.
6 16 LED's gain reduction meter.
You bring the solder (use good quality solder, 1mm diameter max) and the Lunchbox.
The CP5176 kit has an medium difficulty level. Nothing very difficult but a rather large number of components and a good density.
The setup is simple but requires using a good quality AC voltmeter.
XT500 Extender: The XT500 option is a cable extension that allows you to test and setup the module outside the lunchbox while connected.
501 Case: The 501 case option is a standalone, single slot lunchbox with PSU.The XT500 Extender is not needed with the 501.
Assembled Product: If you prefer not to DIY, choose an Assembled product. It comes fully assembled, ready to use.
