API 5500 Stereo/Dual Mono 550 Equalizers with Range Switch Multi-Channel Compressors & Limiters Key filter options include high

Key filter options include high pass and band-pass filtering

sharp knee type compression that has a much more severe limiting effect

API's 5500 also features a true hard-wire bypass which wires the output connector directly to the input

which ranges from 9Hz to 101kHz with less than 1% distortion

API 5500 Stereo/Dual Mono 550 Equalizers with Range Switch Multi-Channel Compressors & Limiters Key filter options include highAPI 5500 Stereo Dual Mono 550 Equalizers with Range Switch Typical of API products, the 5500 contains no integrated circuits in its signal path. The gain comes from two hand built 2520 Operational Amplifiers in each channel. The balanced input is handled by a 2510 Discrete Operational Amplifier, which is similar to the 2520, but without the high current output stage. A key component of the API sound, the 2520 coupled with the API 2503 output
