Patented Dynamizer technology
When it comes to amplifying the signals delivered by electric instruments, you’ve got to separate the wheat from the chaff. Unlike mixed or mastered signals, electric instruments usually deliver extremely high signal peaks which, when raised in gain, produce nasty distortion. How an amplifier responds to these signal peaks can therefore be seen as one of its most essential quality features.
Many manufacturers use limiters preceding the power stage to limit dynamic signal peaks. However, the problem is the preamp, which is why Behringer equipped the BX4500H with unique Dynamizer preamp circuitry that gives you a lively and punchy sound with signal peaks–even if the amp reaches its power limits. Extreme signal peaks are limited effectively while the average level and hence the power of the overall signal is raised. The sound gets more vivid and powerful in character, without any unmusical distortion. With its limiter in the power stage it is virtually impossible to overdrive the ULTRABASS BX4500H.
The Shape function on the BX4500H provides a revolutionary type of filter that you can use to modify your bass sound in full detail. Extreme filter settings will give your bass sound more power. For example, if you want to play a live bass solo but the sound doesn’t cut through, set up a solid basic sound plus a very distinctive solo sound using the SHAPE filter. Connect your footswitch to control the SHAPE filter and you’re all set.
The Shape filter is also handy for using two different bass guitars. Maybe you want to change from a jazz bass to a fretless bass, and vice versa–two instruments with a completely different sound. Use the Shape filter for your fretless sound, and the basic sound for the jazz bass. Problem solved.
Extremely low bass sounds playing one octave below the lowest available bass guitar frequency are quite trendy in current music productions. Often, you can do this in studios only, because most bass amplifiers have no sub-harmonics function. Not so with your BX4500H: the ULTRABASS processor gives you the ultimate tool to shape up-to-date sounds.
You’ll be surprised how deep your bass can sound with the ULTRABASS function of your BX4500H. Extreme settings can be particularly interesting if you want to give your sound some flavor in the treble range. By the way: when you use the SHAPE filter set to a low cut-off frequency (which is a nice setting for growling sounds), but feel that there’s not enough power in the bass range, the sub-harmonics processor will be there to help you: even though the sound is still growling, now it has much more depth.
The ULTRABASS function can easily be switched on and off via the supplied footswitch. This allows you to fine-tune certain passages only.
