PANEL DESCRIPTION
1. MASTER VOUME CONTROL
2. LINE INPUT SOCKET
This is a standard ¼ inch mono jack socket.
3. LINK OUT SOCKET
For connect to another equipment.
4. POWER ON/OFF SWITCH
This switches the main power on and off in the amplifier. When you turn on the power, it will
have about 2 seconds delay to protect the speaker.
Do not leave the amplifier plugged into a power source for long periods of time when not in use.
5. AC INPUT SOCKET & FUSE
Connects the amplifier to AC power supply. Always use a grounded plug and make sure
the AC cable is more than 3A rating at 250-volt AC. If you require a longer AC power cord,
we recommend the PJB heavy-duty 20 foot power cords. These are available as an
accessory. If fuse needs replacing, use a slow blow ¾ inch fuse rated at 2.5 amps.
6. IEC POWER OUTPUT SOCKET.
This is a non-switched socket to provide power for effects units or other ancillary equipment.
Maximum power rating is 500 watts.
7. AC INPUT -VOLTAGE SELECTOR.
Used to adjust the input rating (110-120 Vac/60 Hz and 220-240 Vac/50 Hz), please just insert
the mains power plug into the socket-outlet with voltage within the setting of the selector. The
current ratings of mains fuse links are different for different input rating (see marking for
details), and the fitted mains fuse link was just related to the input rating as setting of the
selector during factory assembly line work, please ask a qualified personnel to help you
replace the mains fuse link before you adjust the voltage selector. Never try to run the
amplifier on a 220-240volt supply when switched to 110-115volt. This can possibly cause
major damage to the amplifier.

TRANSPORTING AND STORING THE PB-300
When transporting in a vehicle, it is recommended that you use an external case or heavy-duty
cover to prevent it being damaged by falling over or other objects falling on it.

•Do not store in temperatures below -20 Degrees C or above 40 Degrees C.
