Introduction The CP540 compressor is a vintage style compressor with discrete circuitry similar to that of a Neve 2254. It features a side-chained high pass filter that can be set to: 50Hz, 100Hz, or 7kHz. This enables the user to prevent bass frequencies from triggering the compression or with the 7kHz setting it becomes a wonderful de-esser. You can also stereo link two CP540s together with a TRS patch cable, turning the CP540 into a great stereo compressor for drums, piano, or your master bus! This feature can be switched off on the front of the compressor, so you can easily go back to dual mono compressors without the need to unplug the cable. The CP540’s ratio can be set from a mild 1.5:1 ratio up to a 6:1 setting. Specifications: XLR and TRS i/o Frequency Response: 20 Hz 20 KHz +/- 0.5 dB. Sensitivity: 20 dBu maximum at 1 Khz Input impedance: 50K Ohms (Balanced) Output impedance: 200 Ohms (Balanced) Noise: Less than -80 dBu Maximum Output Level: 20 dBu Total Harmonic Distortion.

Combined post for more than one unit. I’ve put used because of the following alterations These new units have been superceded with Panasonic long life (5000hrs) +105 capacitors People who who have bought these are saying how good they are T he power plug is 2 pin, but i will supply the UK adapter if needed This is a top compressor based on the Neve & is faithful to the original. The adjustable filter can reduce the ammount of bass or top end from being compressed. The box is original, though it says Stereo, only because 2 units can be linked together. The CP540 is a professional Compressor, it features 5 switchable filters in the detector side chain: 60, 90, 130, 200 and 440Hz. This enables the user to custom. Tune the compressor behavior to prevent bass frequencies from triggering the compressor. In practice, this prevents the low end from dominating compressor. It will give you clean and effective compression control. The CP540 Compressor also has an external side-chain input, which gives you even more control. Great engineers know how important smooth bus compression is for adding that final polish to your tracks. The CP540 provides you with a wide range of compression, from a mild 1.5:1 ratio to a heavy 10:1 setting. Frequency Response: 20 Hz 20 KHz +/- 0.5 dB. Sensitivity: 20 dBu maximum at 1 Khz. Input impedance: 50K Ohms (Balanced). Output impedance: 200 Ohms (Balanced). Noise: Less than -80 dBu. Maximum Output Level: 20 dBu.
