The Sound
As with all the best gear, the Helios sound is not transparent, but
adds a distinctive tonal quality to the recording. Part of the Helios sound was made up of the flattering mic preamps with the Lustraphone transformers, but the mic pres were only part of the sound.
The quirky EQ section of the Helios is where the design really shines.
With
only three bands, the simple yet powerful EQ imparts colorful tonality, and is anything but neutral. Yet it can be pushed to its most extreme boost settings while retaining openness and clarity.
The treble band is a beautiful sounding fixed 10kHz shelf EQ as it steps through its ten gain positions.
The bass band functions as either a 50Hz shelf filter with selectable cuts (-3,-6,-9,-12,-15 dB), or a four-frequency selectable (60, 100, 200, 300) peak EQ.
The bass peak EQ is odd in that even when the gain control is set at 0 dB, there is still a dramatic boost in band signal (roughly 2 dB!). The mid band operates as a frequency selectable peak (PK) or trough (TR) EQ.
This mid band is unique in functionality because the peak/trough is assignable with the flip of a switch. This makes it handy for finding and setting notch cuts—turn up the gain pot and set the switch to “peak” to find the offending frequency—then simply switch to “trough” to cut. The mid band has eight stepped frequencies to choose from
(700 Hz, 1, 1.4, 2, 2.8, 3.5, 4.5, 6 kHz).
