INTRODUCTION

A series of compact ampliﬁers for Bass instruments like nothing you have seen or heard before. These full frequency,

extended headroom, integrated combo amps could be used for virtually any ampliﬁed instrument but are speciﬁcally tuned

to the unique needs of Electric and Upright Bassists.

Our considerations in these amp designs were multifold and our objectives are to provide:

• An affordable amplier for the discerning musician.

• A gigging amplier for the seasoned professional.

• A teacher’s amp where both the student and the teacher can plug in simultaneously while playing musical examples

with a music player through the auxiliary input.

• An amp for rehearsals, where space and sound levels are limited.

Here is a short explanation of the underlying design concepts.

CLASS A OPERATION

Class A ampliﬁers are typically more linear and as such are less complex than other ampliﬁer classes. In Class A ampliﬁers, the

ampliﬁcation circuitry is designed so that it is always conducting electrical current. This means that the active elements are always on,

thus avoiding the problem of crossover distortion.

LOW-Z CIRCUITRY

Thermal noise is a critical design issue when it comes to audio electronics. By lowering the impedance of components inside an

electronic circuit, the overall thermal noise is substantially reduced. The Low-Z circuitry inside all of our ampliﬁers makes it possible to

achieve consistently noise-free operation.

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 (THD) when most amps are

rated at between 5-10% distortion (that means that to get your 20 Watt out of a 20 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 ampliers, 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.

SAFETY INSTRUCTIONS

Caution: To reduce the risk of electrical shock, do not remove the

cover as there are no user serviceable parts inside. Refer servicing

to qualiﬁed personnel.

This symbol, wherever it appears, alerts you to the presence of noninsulated

dangerous voltage inside the enclosure - voltage that may

be sufﬁcient to constitute risk of shock.

This symbol, wherever it appears, alerts you to important operating

and maintenance instructions in the accompanying literature. Read

the manual.

WARNING!

This ampliﬁer is capable of producing high sound pressure levels. Continued exposure to these high sound pressure levels

can cause permanent and irreversible hearing damage. Ear protection is recommended if unit is operated at high volume for

long period of time. If you experience any hearing loss or ringing in the ears you should consult a doctor.

IMPORTANT SAFETY INSTRUCTIONS

1. Read these instructions

2. Keep these instructions

3. Heed all warnings

4. Follow all instructions

5. Do not use this apparatus near water

6. Clean only with dry cloth.

7. Do not block any ventilation openings. Install in accordance with the manufacture’s instructions.

8. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus

(including ampliﬁers) that produce heat.

9. Do not defeat the safety purpose of the polarized or grounding plug. A polarized plug has two blades with one wider

than the other. A grounding plug has two blades and a third grounding prong. The wide blade or the third prong is

provided for your safety. If the provided plug does not ﬁt into your outlet, consult an electrician for replacement of the

obsolete outlet.

10. Protect the power cord from being walked on or pinched particularly at the plugs, convenience receptacles, and at the

point where they exit from the apparatus.

11. Only use attachments/accessories speciﬁed by the manufacturer.

12. Use only with the cart, stand, tripod, bracket, or table speciﬁed by the manufacturer, or sold with

the apparatus. When a cart or rack is used, use caution when moving the cart/apparatus

combination to avoid injury from tip-over.

13. Unplug the apparatus during lightning storms or when unused for long periods of time.

14. Refer all servicing to qualiﬁed personnel. Servicing is required when the apparatus has been damaged in any way,

such as power supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus has

been exposed to rain or moisture, does not operate normally, or has been dropped.

FOR BC10, BC20, BC40, and BC80:

These ampliﬁers are double insulated electrical appliances whereas BC150 has a protective earthing/grounding

connection and will be discussed in the next chapter.

This equipment is a Class II or double insulated electrical appliance. It has been designed in such a way that it does not

require a safety connection to electrical earth (grounding).

FOR BC150:

1. The apparatus should be connected to a mains socket outlet with a protective earthing/grounding connection.

2. Replace fuse with identically rated fuse and never bridge defective fuses. Before changing fuse, disconnect

power cable from unit!

TROUBLESHOOTING

When your unit seems to not work properly, take a few minutes to troubleshoot before calling service. You can save yourself

time and money by doing it yourself, because the source of problem is often something quite simple.

What is the problem?

• There is no sound from the amp and LEDs don’t light up.

- Check your AC outlet

- Outlet is ok. -> Check power cord, unit fuses (BC150 only, BC,10, BC20, BC40 and BC80 has no user

serviceable fuses) and power switch.

- No power in outlet. -> Check house fuse box.

• There is no sound from the amp with LEDs Lit.

- 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.

- There is no hum in the speaker. -> Internal speaker or power amp may need serviced.
