500 Series microphone preamp with authentic Harrison sound and legendary filters
The Harrison 32Cpre+ brings the characterful sound of the Harrison 32Classic console to the compact 500 Series format for the first time . At its heart is a high-quality, Jensen JT-MB-CPCA transformer-coupled microphone preamp, which delivers precisely the warm, rich yet open fundamental sound for which Harrison has been prized for decades.
Anyone looking for a preamp with a musical low end, open midrange and smooth highs won’t find a sterile piece of kit here, but rather a channel strip with real personality. The 32Cpre+ is designed for recording sessions where the sound needs to be just right right from the source.
Harrison consoles have played a part in countless legendary productions. Names such as Michael Jackson, ABBA, Led Zeppelin, Queen and Donald Fagen epitomise a studio sound that remains the benchmark to this day. The 32Cpre+ translates precisely this character into a modern module format that integrates seamlessly into any 500 Series setup.
What you’re getting isn’t just any preamp module, but a piece of classic American studio tradition in a significantly more compact form.
At the heart of the 32Cpre+ is the Jensen JT-MB-CPCA transformer, which is largely responsible for its distinctive sonic character. The preamp offers +20 to +70 dB of gain, allowing it to handle not only classic condenser microphones with ease, but also dynamic and ribbon microphones with plenty of headroom.
This is a real advantage, particularly with quieter sources or ribbons with a distinctive character, as you get enough gain without the sound becoming thin or harsh.
A Harrison preamp without filters would only be half the story. That’s why the 32Cpre+ comes equipped with the well-known low-pass and high-pass filters. Both operate with a musical slope of 12 dB per octave, whilst the high-pass filter also features a distinctive 3 dB resonance peak.
The high-pass filter covers 25 Hz to 3.1 kHz, whilst the low-pass filter operates from 160 Hz to 20 kHz. In practice, this feels less like technical tidying up and more like genuine sound shaping. That’s exactly what makes Harrison filters so popular.
On the front panel is a combo socket comprising an XLR and a 6.35 mm jack, allowing you to connect microphones or instruments directly. This saves you having to go round to the back of the Lunchbox rack and makes the 32Cpre+ particularly convenient for everyday use.
It also features 48V phantom power, polarity reverse, a -20 dB pad, HiZ switching and an input overload LED. This means the module is clearly designed for practical tracking and does exactly what it’s supposed to in the studio: work quickly, musically and reliably.
The 32Cpre+ is not a specialised tool designed for just one task. It is suitable for vocals, acoustic guitars, electric guitars, bass, drums, synths and line signals, always with the aim of making sources sound slightly fuller, rounder and more musical. This module really comes into its own when you’re looking to add more character right from the recording stage.
The sound isn’t merely ‘warm’; it has that subtle blend of density, openness and natural colouration that you immediately recognise in good analogue preamps.
With many preamps, gain is only half the story. Things get exciting when a module doesn’t just turn up the volume, but gives a source shape, weight and a certain natural presence right from the input stage. That’s exactly where the 32Cpre+ comes into its own. The combination of Jensen transformers and Harrison filters, in particular, makes it a tool that you don’t just use, but specifically choose.
