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
Excessive	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
ENGLSIH
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.	The tubes need a few minutes until they have reached their optimal operating temperature (TubaPath).
7.	Switch MUTE off and the red 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 (X-Treme).
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 setting. The Tube Sat LED indicates the saturation of the tubes, which will produce a more
	compressed and overdriven sound (TubePath).
