I realized we never did any kind of formal release for the H9, things have been so dodgy with parts that I didn't feel like I could really push anything after the first batch which was mostly sold before it was finished. Can't have that, now that we have units in stock!
We are quite happy to formally (re)introduce the Iron Age Audioworks H9 Mic pre and Equalizer to RGO.
The H9 is a mic preamp, high pass filter, and equalizer in the 500 series format. The mic preamp and EQ combine for an instantly recognizable character and are all incredibly useful professional tools for tracking or mixdown.
The H9 features a transformer coupled, discrete Class A mic pre. The amplifier gives a snappy, open vibe with a woody character that’s perfect for any source. It handles transients with an ease and clarity that captures the vibe like you’re in the room. A Jensen input transformer carefully selected to match the amplifier plays a key role in the sonics and low-noise performance of the design.
A single precision rotary switch controls the input mode. Mic gain is available from 0 to 70 dB in 10 dB steps. The clockwise positions activate a line level input at +10, 0 and -10 dB gain, and automatically disconnect the 48V phantom power from the input.
The H9’s equalizer is a classic three band passive design. Each band uses a precision rotary switch for control. The high shelf gives unmatched air and sparkle with an effortless feel. The inductor mid band has 11 frequencies selected for enhancing individual features or helping tracks sit just right in the mix. The continuous gain knob paired with a boost or cut switch allows for fast “seek and destroy” identification and handling of problem frequencies. The low band acts as a 50 Hz shelf in cut in 3 dB steps, and a continuously variable peaking response with five center frequencies in boost. A separate discrete high pass filter is set for 80 Hz to tame unwanted rumble and can be combined with the low band to deliver powerful, authoritative lows. A second discrete gain stage acts as makeup gain for the EQ, and a discrete Class A buffer drives the line out.
This style of equalizer has been used on countless records – a testament to its flexibility and musicality for any voice, instrument, or genre.
As with all Iron Age products, the H9 is as discrete as possible, designed and made in the USA.
