Presentation
The Ashdown UK-OBM-300 proves that brute force can sometimes be found in tiny boxes. Imagine a rhythm section rumbling with authority, while your amp barely occupies the space of a cereal box in your carry bag. This head delivers 300 Watts of pure listening pleasure, with a dynamic reserve that respects every nuance of your playing.
The versatility starts right at the front panel, with a shockingly effective 5-band EQ. You can sculpt your sound by acting on strategic frequencies such as the low-mids at 220 Hz or the brightness at 7 kHz. The Pre-shape switch tops it all off by applying a response curve that instantly magnifies the natural character of your bass.
When it comes to connectivity, this little bombshell leaves no stone unturned to facilitate your performances. The two High and Low inputs can accommodate both passive microphones and power-hungry active systems. The balanced DI output is your best ally for sending a clean, professional signal directly to the club or auditorium mixing console.
Globetrotters will appreciate the auto-voltage system, which detects mains voltage between 115 V and 230 V. Whether you're playing in a Paris bar or on stage in New York, the electronics adjust without you having to do a thing. The integrated effects loop (Send/Return) completes the picture for inserting your favourite modulation pedals or compressors.
Ashdown's sturdiness is backed by a 5-year warranty, proof of our total confidence in the longevity of our components. With a signal-to-noise ratio in excess of 80dB, you'll enjoy a crystal-clear acoustic background.
