- Read these instructions  
- Keep these instructions  
- Heed all warnings  
- Follow these instructions  
Caution: To reduce the risk of electric shock, do  
not open the amplifier’s case. Avoid exposure to  
rain or moisture. No user serviceable parts insi-  
de, refer all service to a qualified technician. No  
vessel filled with liquids, such as vases shall be  
placed on top of the unit.  
This symbol, wherever it appears, alerts you to  
the presence of dangerous non-insulated voltage  
inside the case. Risk of electric shock!  
This symbol, wherever it appears, indicates to  
important operating and maintenance instruct-  
ions in this user manual. Please read the manual.

Congratulations on the purchase of the new Warwick amplifier head/combo. Please read through these  
instructions before connecting and operating the device. If you keep to the guidelines set out in this  
manual, you will soon be able to appreciate the quality of this new Warwick amplifier. Please keep this  
instruction booklet handy in case you need to consult it again. Please send the PASSPORT to the address  
indicated therein.  
RECOMMENDATIONS  
The following recommendations are designed to ensure that the device always functions reliably:  
Never open the casing! To do so would expose you to the risk of an electric shock. Should repairs prove necessary, leave  
them to qualified service personnel.  
Avoid dust and high moisture levels, direct sunlight and extremely high or low temperature.  
Safeguard the device from excessive vibration. Always place the unit on a stable and horizontal surface.  
See to adequate ventilation. The device should not be placed on soft surfaces (carpet, cushions, etc.). When mounting  
it in a rack, make sure that the rear and lateral cooling vents remain unobstructed.  
Avoid leaving the unit near radiators or other objects producing heat.  
Internal components should only be adjusted or cleaned by qualified service technicians. Ensure no object or liquid  
penetrates the device through its cooling vents.  
When replacing a fuse make sure you fit in one of identical value!  
Have the device examined by a qualified service technician in the following cases:  
the mains lead 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 casing damaged.  
HINTS  
- This apparatus shall not be exposed dripping or splashing and that no objects filled with liquids, such as vases, shall  
be placed on the apparatus.  
- This apparatus should be connected to a MAINS socket outlet with a protective earthing connection.  
- Mains plug or appliance connector shall be used as the disconnect device, so mains plug or appliance connector should  
always remain readily operable.  
- If the apparatus shows any malfunction, immediately disconnect the main power cord from the mains socket.  
- Do only operate effects pedals in-between the instrument and the amplifier, as these devices are not designed for the  
supplied load of an effects loop.  
- Remove the plug whenever changing a fuse.  
- Only ever replace a fuse with another of the same type. Never bridge defective fuses.  
- Make sure the top and bottom of the device are properly ventilated and that the vents are not blocked.  
- Do not subject the device to excessive vibration or hard jolts as these could damage the device.  
- Don't undertake repairs yourself.  
- Only allow the case to be opened by qualified personnel. (Remove the plug).  
- Repairs should only be undertaken by qualified personnel.  
SHOULD YOU FIND YOURSELF ONE DAY WONDERING: "WHY IS THERE NO SOUND COMING OUT?"  
please check:  
- all stub cables,  
- all connections of these cables  
and proceed anew by following the guidelines of the chapter GETTING STARTED. Possibly the problem reveals to be an  
operational error.

PROTECTIVE CIRCUITS  
Your new Warwick amplifier is equipped with a series of circuits to prevent it from destruction in case of inadequate ope-  
rating conditions:  
Power-up delay:  
When the unit is switched on, the SPEAKER OUT sockets are activated with a slight delay to  
protect the loudspeakers.  
Short-circuit:  
In the event of a short-circuit at the power amp outputs, this feature prevents the output stage  
transistors from destruction by quickly reducing current.  
Direct current (DC): This circuit continuously monitors the power amp output for direct current and protects the loud  
speakers from overload should a transistor burn out.  
HF oscillation:  
By switching the power amp off, this safety feature prevents from damages that could be caused  
by frequencies in excess of 20 kHz (feedback, etc.).  
Excessive  
temperatures:  
Should the temperature-regulated fan cooler prove to be insufficient in extreme conditions, this  
circuit protects the output stage transistors from destruction by switching the device off.  
Note:  
Note: You can recognise that one of these circuits has been activated as a result of a fault, when  
the MUTE LED glows continuously even though you have not selected the MUTE mode. In case  
of a shortcircuit please check the speaker cable. The amplifier must then be switched off and on  
again, to get back into playing mode after having removed the short-circuit. In any other situati  
on the amplifier switches automaticallyback to playing mode as soon as it detects the fault has  
disappeared (e.g. the amplifier has overheated and cooled down again).  
GETTING STARTED  
1. Make sure that loudspeakers capable of sustaining the load of a bass signal are connected to the SPEAKER OUT  
sockets (the speaker cables should meet a cross-section of at least 2 x 1.5 mm).  
2. Check that the mains supply has been plugged in and that all external (effects) units possibly used are correctly con-  
nected and operational.  
3. Set the MASTER control to zero.  
4. Plug your bass guitar into the amplifier's INPUT with a shielded line-cable.  
5. Press the POWER switch to turn the device on.  
6. Switch MUTE off and the red LED will extinguish.  
7. Switch the COMPRESSOR off (the 2-coloured LED will extinguish).  
8. Turn all volume controls of your bass guitar on to their maximum.  
9. Adjust the GAIN control until the (loudly) played bass signal flashes the Clip LED.  
10. Set the MASTER control to the volume you wish to play at.  
11. Adjust the sound that you wish with the controls and switches described in the respective chapters FRONT PANEL  
CONTROLS.  
12. If necessary readjust GAIN.
