Transform car battery power into ROCKSTER energy
If there's not a 230-volt power port to hand a lot of devices flashing
red won't often survive the journey. But not the ROCKSTER. With the
right equipment the ROCKSTER can be connected directly to your car
battery for a quick recharge for lasting sound.
To connect the car
to speaker we have the "car battery connecting cable set" available as
an accessory. Each of our ROCKSTERs have a PA port for the connection.
Safety First – connect with ease
Thanks to coloured cables you can easily tell where each cable belongs,
meaning the chance of failure is nearly impossible (Plus = red / Minus =
Blue). The bayonet pole terminals also ensure a secure connection. The
pole clamps are simply placed on the pole and locked in place with the
practical bayonet lock.
In addition, the cable contains an integrated 60 amp fuse to prevent damage to the ROCKSTER due to overvoltage.
"Power Mode" switch for power supply selection
Power is supplied from the car battery as soon as the "Power Mode"
slide switch on the rear of the ROCKSTER has been set to the "External"
position and the car battery is correctly connected.
Test the cable for up to 8 weeks.
