The H2 Audio Helios 0011/Stereo is a 19" rack-mount format production module that takes the original 0011 channel to a whole new level. This module features the original Helios 2128 microphone preamp circuit with 70 dB of gain in 5 dB increments. Plus a -20 dB pad, Lustraphone input transformer, a balanced line-in section, inductor based LF/MF EQ section with selectable LF and MF and fixed 10 kHz HF controls, phase control, EQ bypass and selectable High Pass filter with original 40 Hz and 80 Hz filter points and 48V phantom power.
The 0011/Stereo mic preamp features two channels replicating the legendary Helios 2128 preamp circuits. The 0011/Stereo boasts a gain range of 25 - 75 dB in 5 dB increments, with Lustraphone input transformers providing 20 dB gain before the preamps. Onboard features include -20 dB pads, +48V phantom power, EQ Cut switches, and Phase switches. The 0011/Stereo has an added output amplifier with output transformer, all of original Helios design, allowing the H2 Audio 0011 to drive a 600 ohm load up to 25 dB before clipping (owners of classic Helios modules will agree that this was a major issue when trying to use a classic Helios in a custom rack).
The inductor based LF/MF EQ section features selectable LF and MF and fixed 10 kHz HF controls. It also features Phase control, EQ bypass and selectable High Pass filter with original 40 Hz and 80 Hz filter points. The Bass Hz rotary switch features selectable 60, 100, 200, or 300 Hz boosts variable or 50 Hz filters with selectable 3, 6, 9, 12, or 15 cuts. Mid kHz rotary switch includes 0.7, 1, 1.4, 2, 2.8, 3.5, 4.5, or 6 kHz boost or cut. 10 kHz rotary switch generates bell-shaped boosts or cuts at 10 kHz by -2, -4, -6, -8, -10, +2, +4, +6, +8, or +10 dB. The PK/TR switch designates the midrange EQs as either peaks or troughs.
