- Page 2 A) Inputs Junior can be powered from 90-250V AC line voltage through an IEC connector, or different battery types through a XLR4M connector. When both sources are connected to Junior, the AC line voltage is given priority and charges the battery.
- Page 3 Validated parameters are stored in non-volatile memory and held even when Junior is turned off. When Junior is turned back on, it checks if the battery has been disconnected. If the same battery is still connected, the settings are automatically reloaded from the non-volatile memory.
- Page 4 2) SBS Battery (Smart Battery System) When an SBS is connected, Junior recognizes it as such, and retrieves chemistry and nominal capacity information from the battery. This data is displayed on the OLED screen with the related charging voltage and current.
- Page 5 B) Outputs Junior has six outputs on its rear panel for powering the sound gear. Four are switched outputs, controlled by switches on the front panel. Two are unswitched outputs that are powered when Junior is turned...
- Page 6 It provides 5V, 20W, i.e. 4A max. on stacked ports. The four switched outputs are controlled by illuminated toggle switches on Junior’s front panel: on green toggle, the respective switched output is activated at the correct voltage. on red toggle, the output voltage is too low for the respective switched output.
- Page 7 2) Unswitched Outputs Two unswitched outputs are powered when Junior is turned on. These allow the user to connect accessories that do not require regulation such as lights, fans, additional USB chargers, etc. These outputs are filtered and protected by a resettable fuse. Since they're unregulated, the output voltage can vary between 13.7V (AC...

- Page 11 c) System Screen: The software version and its build date (DD/MM/YY) ; The language used ; The system mode: [Admin OFF] or [Admin ON] ; And the names of the great designers of this beautiful device !
- Page 12 The four illuminated LED toggle switches for the main outputs are described in section B-1 “Switched Outputs”, above; Junior’s yellow main power switch, which is not an LED, is used to turn it on and off: press for one second to turn on, and press...
- Page 13 On the back panel, a toggle switch next to the AC line voltage input allows the user change Juniors grounding between Lift and Earth. When the toggle is in the position marked “Earth” it connects Junior electrical ground to earth (chassis).
