H2 Audio 008 Rack

H2 Audio Helios Channel
With the rise of home recording and hybrid recording methods we have created The Helios Channel, featuring the classic 0011 mic pre/EQ and the F760 compressor limiter, all in a rugged steel 2U 19” rack to give you the ultimate classic recording chain. The Helios channel also features the Acme Audio Motown DI’s custom input transformer for its DI input. This transformer is electronically switched directly to the 0011’s mic-in connector when activated by a selector switch on the front panel. Also featured is 48V phantom power, output fader control and Link/Ind switch which allows The Helios Channel to be operated as a channel strip or as independent units complete with separate input and output connectors on the rear of the unit. The Helios Channel is powered by the same external PSU as the 0011, and 8-channel rack and up to 4 units can be used off of one supply.

H2 Audio 002 Rack for H2 Audio 0011 modules
The Rack 002 offers 2 slots for H2 Audio 0011 preamp + EQ modules in a proprietary format. It is delivered with an external power supply and a 6-pin power cable.

Also available in 8 slots rack for 0011 modules. See the H2 Audio 008.

H2 Audio 0011 Mic Pre and 3-Band EQ
The original channel module from so many iconic studio recordings of the past. This module with a proprietary format features the original Helios 2128 preamp circuit with 70dB of gain in 5dB increments. 20dB pad, Lustaphone M10 input transformer. A balanced line in section is also featured. Inductor based LF/MF EQ section with selectable LF and MF and fixed 10Khz HF controls. Also included: Phase control, EQ bypass and selectable High Pass filter with original 40hz and 80hz filter points. The H2 Audio 0011 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 25dB 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). 48V phantom power is supplied by switch on the H2 Audio 8 channel rack.

The 0011 is not 500 Series module and should be powered with its dedicated 002 or 008 slots rack.

H2 Audio 5011 Helios 3-Band EQ
The EQ section from the 0011 in a 500 series package. Featuring an electronically balanced input and transformer balanced output with amp circuit, and the exact same EQ circuit as the 0011.

H2 Audio 2128 Helios Mic Preamp
The mic preamp circuit from the 0011 in a 500 series package. It features the same quality preamp with 70 db of gain, 20 db pad, phase control, 48V phantom power and selectable high pass filter. Also added is a Cinemag input transformer, output amp section with transformer out and output fader.

H2 Audio 0011 2-Channel Mic Pre/EQ
This is a 2U 19” rack stereo pair of Helios 0011s. All features of the 0011 module included in a rugged steel constructed rack.

H2 Audio H760 FET Compressor / Limiter
Undoubtedly one of the best-kept secrets in recording, the F760 designed by AD&R and licensed by Helios is one of the most classic FET comp/limiters ever made. Sold as modules fitted into classic Helios desks and most famously heard on Led Zeppelin’s ‘When The Levee Breaks’ drum recording. A very easy-to-use unit with fixed threshold and 5 pre-selected ratios, selectable attack and release times and separate Limiter threshold. The H760 will allow the user quick adjustment of dynamic control of any audio program and maintain the classic sound of a British FET compressor/limiter.
