The model API Lunchbox 500-6B HC is the successor of the legendary 500-4B 4 position lunchbox. It can hold up to 6 API 500 Series modules. This allows the engineer to bring their favorite API EQs, mic preamps and/or compressors to each session. The Lunchbox has its own power supply with on/off switch and an internal power supply. The input and output jacks are designed as XLR connectors from Neutrik and as D-Sub according to Tascam standard.
