Warwick SUB III Manuel D’Utilisation

4

Your new Warwick amplifier is equipped with a series of circuits to prevent it from destruction in case of inadequate ope-
rating 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 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.

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.).

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.

The combos CL and CCL are equipped with a limiter, that limits the poweramp outputs to 
200 watts (CL), 300 watts (CCL) in order to protect the loudspeakers.

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 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-circuit. In any other situation

the amplifier switches automatically back to playing mode as soon as it detects the fault has 

disappeared (e.g. the amplifier has overheated and cooled down again).

1.

Make sure that loudspeakers capable of sustaining the load of a bass signal are connected to the SPEAKER OUT
sockets, resp. the speaker unit should be linked to the SPEAKER OUT at the combos.

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 

LIMITER off (the 2-colored LED will extinguish, CL, CCL).

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.
13.  Should you seek for a peak limited sound, activate the LIMITER (LED green) and fix its threshold (LED shifts to red)

with GAIN.
