In an age where the landscape of live performances has evolved, with silent stages and in-ear monitoring becoming standard, Ashdown continues to innovate. The NEW Analogue Cab Sim Di output on the Rootmaster EVO III provides bass players with greater control over their on-stage and front-of-house sound.

On the rear panel, a balanced D.I. output via the XLR socket offers a post-EQ and post-effects signal. But the true innovation lies in the customizable filters, which emulate the response of Ashdown's legendary ABM cabinets.
You have the freedom to choose between CAB SIM DI and BALANCED DI outputs via the XLR DI option. Additionally, the enclosure options of PORTED and SEALED allow you to modify the resonance of the output, either extending the bottom end or tightening it up.

The SPEAKER option lets you select between a 10” speaker, known for its tight, defined mid-range, and a 15” speaker, prized for its depth and clarity. The HORN option, featuring an IN or OUT selection, accentuates the high-end frequencies around 5kHz, similar to the presence of a horn in a cabinet.
