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.
Absolutely everything!
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.
