GENERAL INFORMATION
For safe and reliable operation please follow these instructions:
•DO NOT open the amplifier case! You might receive an electrical shock. For any repair refer to qualified service personnel.
•Avoid dust, excessive moisture, direct sunlight and extremely high or low temperatures.
•Safeguard the device from impact. Always place the unit on a stable and horizontal surface.
•Do not block any of the ventilation openings.
•Avoid leaving the unit near radiators or other heat producing devices.
•Internal components should be adjusted or cleaned by qualified service technicians only. Make sure no object or liquid pene-
trates the device through its cooling vents.
•Fuse must be replaced with one of the same type and value to avoid damaging the amplifier.
•the mains cable or mains switch have been damaged,
•objects or liquids have penetrated the device,
•it has been exposed to excessive moisture,
•malfunctions or abnormal operating conditions have occurred,
•the device has been dropped or the case has been damaged.
Have the device examined by a qualified service technician in the following cases:
- Make sure the unit is plugged into a socket outlet with a protective grounding connection.
- Mains plug must be accessible at any time to disconnect it from mains in case of abnormal operation.
- If the device shows any malfunction, immediately disconnect the mains cable from the mains socket.
- Use effects pedals only between the instrument and the amplifier since these devices do not meet the electrical specifications
of the effects loop.
- Unplug the unit whenever changing a fuse.
- Replace fuse only with one of the same type and value. Never bridge defective fuses.

PROTECTIVE CIRCUITS (SWEET 15.3, SWEET 25.2 only)
HF oscillation:
This safety feature prevents from damages caused by frequencies above 20 kHz (feedback, etc.) by
switching the power amp off.
Temperature:
Should the temperature controlled fan cooler prove to be insufficient in extreme conditions, this circuit
protects the output stage transistors from destruction by switching the device off.
Direct current (DC): This circuit continuously monitors the power amp output for direct current and protects the loud-
speakers from overload in case a transistor burns out.
GETTING STARTED
1. Make sure that the mains lead is connected and all external devices (effects) are properly connected and working.
2. Set the VOLUME control (Blue Cab 15.1, 30.1, 60.1) / MASTER control (Sweet 15.3, 25.2) to zero.
3. Plug your bass guitar into the amplifier's INPUT using a shielded cable.
4. Press the POWER switch to turn the device on.
5. Switch off MUTE - the red LED will turn off. (Sweet 15.3, 25.2)
6. Turn up all volume controls of your bass guitar.
7. Adjust the GAIN control until the clip LED flashes. (Sweet 15.3, 25.2)
8. Set VOLUME control (Blue Cab 15.1, 30.1, 60.1) / MASTER contol (Sweet 15.3, 25.2) to your desired volume.
9. Use the sound controls / switches to adjust the sound as described in the respective chapters FRONT PANEL CONTROLS.
10. If necessary readjust the GAIN. (Sweet 15.3, 25.2)
