API L200 225L Modules + L200 PSU 200 Series Compressor Limiter

L200
12-slot rack for API Vision or Legacy Plus L200 series modules.

API’s L200 Rack features a level of flexibility designed to meet the needs of the discriminating engineer/producer. Module interchangeability has always been an API standard and the L200 system follows the tradition. The L200R is fully compatible with modules used in API’s Vision and Legacy Series Consoles, including the 205L Direct Input, the 212L Mic Pre, the 215L HP/LP Sweep Filter, the 225L Compressor and the 235L Noise Gate.

The L200R also features API’s standard 5 Year Warranty, and exhibits the reliability, long life, and uniformity which are characteristic of all API products.

225L
VCA based compressor with auto-makeup gain

The API 225L Compressor is ideal for all studio, live sound and broadcast applications. Regardless of the threshold or ratio settings, the output level always remains at unity. This unique feature allows for real-time adjustments without the need for changing the output level.

Both NEW (“feed forward”) and OLD (“feed back”) methods are selectable on the front panel, providing two choices of gain reduction. NEW gain reduction is typical of the newer VCA type compressors that rely on RMS detectors for the gain control voltage. OLD or Feed-Back method is what most of the classic compressors used for the gain control circuit There also is a SOFT or HARD selector. SOFT provides a more subtle compression resulting in a very natural, less compressed sound. HARD results in a more typical, sharp knee type compression that has a much more severe limiting effect.

Release time is adjusted by rotating the inner concentric R knob. Release time constants: continuously variable from .3 seconds to 3 seconds. Attack time is adjusted by rotating the outer concentric A knob. Attack time constants: continuously variable from 1 millisecond to 25 milliseconds.

API’s 225L is designed for individual channel use, or through the use of the external LINK funcauto-makeuption. Two units can be combined for Stereo applications via a rear access pin. The 225L also has a side-chain input for the detector amplifier.

The 225L can be used in the Legacy, Legacy Plus or Vision Series Consoles, or in the L200 Rack. The 225L Compressor makes use of the 2520 and 2510 op-amps and therefore exhibits the reliability, long life and uniformity which are characteristic of all API products.
