The Dynamic range of contemporary music is so extensive that as a bass player, you need a system fully capable of responding to both your loudest and softest passages, with accuracy and clarity, whilst retaining warmth and musicality.
This can only be achieved by using an amplifier with enough headroom to remain clean under even the most extreme playing conditions, but with features capable of allowing you full tonal control. By engineering an amplifier with headroom that goes five times beyond that of normal bass amplification, we have created a system capable of delivering unbelievable power and sound pressure levels, with incredible punch.
The days of compromising your playing technique and EQ settings to retain maximum clarity are over, these systems are built to respond faithfully and accurately to even the wildest dynamic range! Our range of Marshall Dynamic Bass amplifiers, speaker cabinets and combos have been carefully designed to fulfil all the needs of the serious contemporary bass guitarist. Whatever your style, whatever the application, there is a no compromise Marshall Dynamic Bass System that will be the most responsive and rewarding that you've ever played through.
Where a conventional bass amplifier operates on an RMS to peak power ratio of 1:2, the Marshall Dynamic Bass System casts convention aside by extending this ratio to 1:10. The result in the 7400 model, is a 400 Watt RMS amplifier that delivers peaks of 4000 Watts. This incredible dynamic headroom is achieved by using two discrete power supplies - one more than the typical bass amplifier. Marshall's specially designed Dynamic Bass circuitry constantly monitors the amplifier's input level and when it detects signals that would be too dynamic for a conventional bass amp, kicks in the secondary power supply instantaneously to handle them cleanly. This abundance of headroom allows you to lean fully on the amp's power stage to give you clarity, punch and supremely dynamic performance, with sensitivity the likes of which you won't have previously experienced.
Making the most of the massive peak power levels provided by the Dynamic Bass System's awesome headroom, is an equally impressive pre-amp section to give you total tone shaping and full control.
Features
- Hi and Lo Inputs To match active or passive bass guitars (it does not really matter which input you use, just choose the one which sounds the best for your bass).
- Gain Controls the overall input level and the threshold level of the compressor.
- Valve/Solid State Blendable Input Pre-amp The rotary blend control allows any number of combinations from warm fat vintage valve to sharper more percussive solid state.
- Hi & Lo Primary EQ Controls Rotary controls giving cut and boost of + or -15dB of the basic EQ.
- Deep and Bright Push Switches Add extra depth to the bottom end and more attack to the top end of the primary EQ.
- Compression Smooth operating industry standard compressor with depth control, on/off switch and threshold indicator.
- 9 Band Graphic Equaliser Footswitchable from the rear panel and including cut or boost of frequencies specially selected to maximise dynamic bass performance. The master level control of + or - 6dB allows you to accurately balance levels when the graphic is switched in or out.
- DI Pre or Post EQ Selection Switch Offers a PA or recording engineer the choice of direct signal either before or after EQ has been added and dispenses with the need for DI boxes on stage or in the studio.
