The Legendary Helios Electronics Ltd has resurrected with much anticipation and patience, the Olympic Type69 Series EQ as used by the Beatles, Rolling Stones, Bob Marley, Led Zeppelin and so on. Helios became known as the musician's choice of recording consoles.

Brought in line with modern expectations, these units are built to military specifications with supervision of gear fanatic and music producer Tony Arnold. Endorsed by the late Dick Swettenham, of the original Helios Electronics Ltd, to maintain and service all of the original consoles, Tony later purchased the original company, including all of its circuits and parts.

The Olympic Series is a classic 3-band EQ-Pre module, available in a dual mono 1U rack mount or a mono vertical module. The modern circuit is similar to the original, aside from one vast improvement, the build quality and reliability. The openness and clarity has been upheld with the addition of EQ frequency selections. Tony Arnold explains, "We asked many of the original users of the Helios Desks what they felt was missing, and could we make any improvements. Most wanted the 30 Hz added to the Lo-EQ. In order to meet todays CD standards, some wanted a tight high frequency around 16 k, which has been added without changing the original Helios sound whatsoever."
