WARWICK WA & BC SERIES BASS AMPLIFIERS
OWNER’S MAN AL
Classic sound with modern performance. Manufacturing techniques and component quality has improved drastically over
the last couple of decades. Noise and hum are no longer unavoidable side effects of great sound. So here we have recreated
the “Classic” 10 band graphic EQ powered Bass Amp with big, powerful, tight sound in a modern package.
Our considerations in these amp designs were multifold and our objective is to provide:
• An affordable amp for the serious up and coming musician.
• A seasoned professional’s gig amp.
ere is a short explanation of the underlying design concepts.
CLASS-A CIRC ITRY
Class-A amplifiers are typically more linear and, as such, are less complex than other amplifier classes.
The amplifying element is biased so the device is always conducting to some extent. This means the amplifier is always
on, avoiding the problem of crossover distortion associated with class-AB and -B designs.
LOW-Z CIRC ITRY
By lowering the impedance inside an electronic circuit you lower the amount of thermal noise. In an amp where you have
tone controls that lift mids and highs a considerable amount, proper impedance level makes the difference between
enduring audible annoying hiss, and enjoying a pleasant tonal experience.

DYNAMIC DISTORTION LIMITER™
Distortion occurs when an amplifier works beyond its range, when the power supply cannot supply the power any more to
take the amp higher. A common method to control distortion in amps is to use a limiter, a device that stops the signal going
beyond a specific level. Audio limiters work by setting a threshold signal level where the circuit kicks in and keeps signal
levels within the capabilities of the power supply. This method is not very precise and often causes audible effects such as
pumping and thumps. We designed a circuit that instead reads the distortion level in the power amp and starts limiting as
soon as the amp shows even miniscule amounts of distortion. This means our amps always stay within 0.3% distortion
(T D) when most amps are rated at between 5-10% distortion (that means that to get your 600 Watts out of a 600 Watt
amp you will get it audibly distorted and if you want a clean signal the power will be a lot less).
There are desirable types of distortion, but these are not usually associated with transistor amplifiers, but more commonly
associated with tube amps and effect pedals. Warwick’s goal is to give the user a great, clean sound allowing the user to
decide how much, and what kind of distortion to employ.
INTEGRATED SPEAKER DESIGN
All the speaker drivers and cabinets have been designed in tandem with the electronics to create units that work together
efficiently . Careful consideration has been taken to modify all parameters, thereby achieving the best results in sound and
performance. All components reflect a custom designed solution to give the end user optimum control over his/her tone,
volume and configuration.

PROTECTIVE CIRC ITS
Your new Warwick amplifier is equipped with a series of circuits to prevent it from destruction in case of inadequate
operating conditions:
POWER- P DELAY: When the unit is switched on, the SPEAKER OUT sockets are activated with a slight delay to protect
the loudspeakers.
SHORT-CIRC IT: This feature prevents the output stage transistors from destruction by quickly reducing current in the
case of short-circuit at the power amp outputs.
DIRECT C RRENT (DC): This circuit continuously monitors the power amp output for direct current and protects the
loudspeakers from overload.
HF OSCILLATION: By switching the power amp off, this safety feature prevents from damages that could be caused by
frequencies in excess of 20 k z (feedback, etc.).
EXCESSIVE TEMPERAT RES: This circuit protects the output stage transistors from destruction by switching the device
off if the temperature-regulated fan cooler prove to be insufficient and temperature of device will be too high.
NOTE: You can recognize 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 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 short-circuits. 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).

first, then to the AC outlet and then turn this switch on. It works backwards when you want
disconnect unit – firstly turn switch off, then disconnect cord from the AC outlet and finally
disconnect cord from amplifier.
MAINS IN AC – AC terminal with integrated fuse compartment for connection to the mains power supply. To
exchange the fuse you have to disconnect power cord first and use small screwdriver to remove
fuse carrier. Use only the same size and type for replacement. Using a fuse with a different rating
than specified can cause damage to your amplifier.
T NER O T – Dedicated output for tuners. Signal remains active in this output even when amplifier is muted
which allows for “silent tuning”.

of the effects unit and the output of the effects unit to the RETURN socket. The effects loop is of
the serial type.
LINE O T – Unbalanced output to external devises (auxiliary power amplifier, mixing console etc.).
DI O T – Balanced XLR output to external devices such as PA and studio mixing consoles.
PRE-POST – switch to control the DI OUT. In PRE position the signal at DI OUT is the signal without any
compression or equalization. In POST position signal at DI OUT is fed after the compressor,
tone controls and effects loop.
GRO ND LIFT – Switch to lift the chassis ground connection from the DI output. elps to prevent hum caused
by ground loops.
SPEAKER O T – Output combo connectors (¼” jack and lockable coaxial) for connecting speakers. These are
connected in parallel. Connect only speaker combinations with a summary load equal or greater
than 4Ω.

TRO BLESHOOTING
When your unit seems not to work properly, take a few minutes to troubleshoot before colling service. You can save yourself
time and money by doing it yourself because the source of the problem is often something quite simple.
WHAT IS THE PROBLEM?
1. There is no sound from the amp and LEDs don’t light up. -> Check your AC outlet.
1.1. Outlet is ok. -> check power cord, unit fuses and power switch.
1.2. No power in outlet. -> Check house fuse box.
2. There is no sound from the amp and LEDs light up. -> Check amp gain and/or volume controls, check guitar
controls. If controls are ok and all set above zero then listen for hum in the speaker.
2.1. There is no hum in the speaker. -> Check speaker and speaker cable.
2.2. There is small hum in the speaker. -> Unplug guitar, touch tip of cable and listen.
2.2.1. um is now very loud. -> Check your guitar electronics or try different guitar.
2.2.2. um does not change. -> Replace your guitar cable.
3. Sound quality is poor. -> Replace your guitar cable. If this does not help then check your speaker and speaker cable.
If problem isn’t covered above or if our solutions does not help then contact Warwick service information.
