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.

Con­sumers of recorded music have grown ac­cus­tomed to the im­prove­ments in per­for­mance and sound re­sult­ing from the de­vel­op­ment of high qual­ity, lower cost elec­tron­ics. The bass world has en­joyed lit­tle ben­e­fit from this progress. War­wick%u2019s new line of com­pact Bass In­stru­ment Combo amps is des­tined to change this by in­tro­duc­ing im­prove­ments in cir­cuit de­sign, speaker de­sign, man­u­fac­tur­ing, and much im­proved com­po­nent in­te­gra­tion.


Our con­sid­er­a­tions in these amp de­signs were mul­ti­fold and our ob­jec­tive is to pro­vide:


  • An as­pir­ing bass play­ers first amp.
  • A sea­soned pro­fes­sion­als "res­i­den­tial amp" (to be used for prac­tic­ing and plea­sure play­ing at home).
  • A back­stage tune-up/warm-up amp.
  • A teach­ers 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.


CLASS-A CIR­CUITRY

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 CIR­CUITRY

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 (TM)


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 80 Watt out of a 80 Watt amp you will get it au­di­bly dis­torted and if you want a clean sig­nal the power will be a lot less).

The BC 10, 20, 40 and 80 model com­bos all fea­ture a dual con­duc­tor "mini" power cable for easy con­nec­tiv­ity, sim­ple travel, ben­e­fits of safety, and re­duc­tion of ground hum. The dual pin con­nec­tion has a con­tin­u­ously lifted ground, so no in­ter­fer­ing hum can enter the cir­cuit from out­side sources. The in­ter­nal trans­former is dou­ble en­cased pre­vent­ing high volt­age from ever caus­ing a safety issue. The power switch is lo­cated on the bot­tom rear of the combo to cre­ate max­i­mum prox­im­ity sep­a­ra­tion of high and low volt­age cir­cuits within the sys­tem, this also re­duces the pos­si­bil­ity of un­wanted noise. These are fea­tures that were care­fully planned to pro­vide the high­est level of safety, qual­ity, per­for­mance, and tone.

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. War­wicks 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
