API Audio 500-8B 8 Slot 500 Series Lunchbox


The API Lunchbox 500-8B includes all of the features that have made the 500-6B so well regarded in the industry.

Manufacturer Description:

The new 500-8B includes all of the features that have made the 500-6B so well regarded in the industry, including DB-25 (D-Sub) connectors for easy I/O, universal power supply (100 or 250V, 47 to 63Hz), phantom power, and easy rack-mounting with optional rack-ear kit. Built for robust performance, with new toggle switches for channel linking.

The lunchbox gives an engineer the flexibility to bring along specialized EQ effects to any situation: 550A, 550b or 560. The lunchbox is self-powered. 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:

  • Multi-track recording of acoustic and electronic audio sources
  • Sound reinforcement systems and recording to multi-track formats
  • Multiple facility projects where portability is a plus
  • Broadcast and audio for video production
  • Custom channel input strips



  • 8 Slots with 250 mA of power per slot
  • Full compatibility with API 500 Series and VPR-approved modules
  • DB25 connectivity on the rear panel
  • Phantom Power
  • Optional Rack Ears available for rack mounting
  • toggle switches for channel linking
  • Rubber feet & carrying handle for portability
  • Rugged steel chassis
  • Perfect for remote recording of Vocalist and Instruments

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.
