API Audio

Automated Processes Inc. (API), best known for their now legendary "2520 amplifier," formed in 1968 and continues to use the 2520 op-amp as the cornerstone of all API discrete products. The resulting console meets the needs of the music, commercial and broadcast industries, positioning API as the leading audio broadcast console manufacturer for audio production outfits of any sort. There are now over 700 API consoles around the world, including one at WNYC 93.9 FM, New York City’s premier public radio station. In 2009, Vintage King Audio worked with WNYC on the acquisition and installation of an API Legacy Console in the station’s revolutionary Greene Performance Space. API has also led the way in modular outboard technology with their VPR 500-Series products. Offering their own 512c mic pre, 525 compressor and 550a, 550b and 560 equalizers as the kingpins of the format, these units are fully interchangeable within any 500-Series compatible rack structure, supplying power and input/output connections directly to the modules. Several manufacturers today build modules and racks that are fully compatible with this versatile modular system.

The API 500-6B Lunchbox is a 
6-slot rack designed to accept all API standard 5.25" X 1.5" modules. 
This quality allows an engineer the flexibility to bring along 
specialized EQ effects to any situation: 550A, 550b or 560. The lunchbox
 is self-powered with a rear panel selected AC voltage switch and a 
removable power cord. The input/output jacks are XLR. The lunchbox comes
 standard with a +48 volt internal phantom power supply, bussed to pin 
15 for interface with the API 512c Mic Preamplifier.

API makes several modules for the 500-6B, including the 512c Mic 
Preamplifier, the 525 Compressor, the 527 Compressor, the 550A 3-band 
EQ, the 550b 4-band EQ and the 560 Graphic EQ. Combinations of these 
modules make perfect stereo recording packages (two 512cs and two 550bs)
 or vocalist's box (one 512c, two EQs and one 527). 
 
Other uses for the versatile lunchbox include: 
<ul><li>Multi-track recording of acoustic and electronic audio sources</li><li>Sound reinforcement systems and recording to multi-track formats</li><li>Multiple facility projects where portability is a plus</li><li>Broadcast and audio for video production</li><li>Custom channel input strips </li></ul>
NOTE: The older 560A 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.
