Product Description

Don't risk damaging or underpowering the 500 series modules you've invested in so significantly - pick the lunchbox from THE brand that developed the 500 series format. This six slot lunchbox has all the power and current your modules will ever ask for. This unit is also remarkably well built, with a built in power-supply, which means that if you're getting this lunchbox as part of a mobile recording rig, you won't have to carry heavy external power supplies or keep up with wall warts or in-line brick style power supplies.


THE 500 Series Lunchbox

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 has an internal power supply 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:

  • 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

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.
