Introducing the brand new WA 300s Bass Head. This workhorse includes a 10 band graphic equalizers, bass and treble controls, adjustable compressors and passive and active inputs for all your tonal needs.
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.
Here is a short explanation of the underlying design concepts.
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.
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 (THD) 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.
