The API Model 500-6B six position rack is designed to accept many different API "standard" 5.25" X 1.5" modules. This allows an engineer the flexibility of bringing along specialized EQ effects to any situation. The 500-6B comes self-powered, with a rear panel selected AC voltage switch, and a non-removable power cord. The input/output jacks are the two standard patch-bay jacks found in every professional recording console; large frame 1/4" or the "TT" style smaller jack. In addition, the 500-6B is available with XLR jacks. This eliminates the need for special adaptors and custom cables.
The 500-6B comes with "nominal level" jumpers located on the connector board. Although it comes factory set at +4, the levels for either the input and/or the output can be changed to -2. This can be accomplished easily by using needle-nose pliers. Instructions are printed on the connector board for the nominal selections. Extra jumpers are also supplied and attached to the connector board just in case a channel jumper gets lost.
The 500-6B comes standard with a +48 volt internal phantom power supply, bussed to pin 15 for the API 512C to access. It must be noted that the 560A series equalizer may use pin 15 for a "direct output" and must be disabled on the 560A circuit board edge connector by cutting a trace. This will eliminate 48 volts from damaging the 560A series equalizers. If in doubt, feel free to contact the factory.
API makes several modules for the 500-6B, such as the 512C mic preamp, the 525 compressor, the 560 Graphic EQ, and the 550B four band EQ. Combinations of these modules make perfect stereo recording packages (two 513C's and two 550B's) or vocalist's box, (one 512C, two EQ 's and one 525 compressor).
