5 Meter 4 Pin Neutrik Cable for BOB's 3 outputs to SOLO8 unit's inputs. The BOB accepts the normal 5 Pin Neutrik. But since the SOLO8 does not require the +48 volts that is also on the PSU. We decided to changeover to a 4 pin XLR just in case someone used a different 5 pin standard and "the purple smoke appeared". The BOB's fuses would have blown instead of your SOLO8. Although the normal PSU can be used with any 500 series rack with the standard 5 pin XLR pin outputs that most use.
