PROTECTIVE CIRCUITS
Your new Warwick amplifier is equipped with a series of circuits to prevent it from destruction in case of inadequate operating
conditions:

When the unit is switched on, the SPEAKER OUT sockets are activated with a slight delay to protect the
loudspeakers.

In the event of a short-circuit at the power amp outputs, this feature prevents the output stage transistors
from destruction by a fast responding current limitation.

In order to protect the loudspeakers the combos CL and CCL are equipped with a limiter that limits the
power amp outputs to 200 watts and 300 watts respectively.

D is continuously on even though you have not switched on MUTE. In case of a short-circuit 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-cir-
cuit. In any other situation the amplifier automatically switches back to playing mode as soon as it detects the fault has disappea-
red (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 S
SP
PE
EA
AK
KE

T sockets,
meaning the speaker unit should be linked to the S

T at the combos.
2.
Make sure that the mains lead is connected and all external devices (effects) are properly connected and working.
3.
Set the M

5. Press
the

7. Switch
the

8. Turn up all volume controls of your bass guitar.
9. Adjust
the
G

11. Use the sound controls / switches to adjust the sound as described in the respective chapters FRONT PANEL CONTROLS.
12. If necessary readjust G
