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
.
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).
