Choose the best analog channel strip - guide.

The legendary sound of SSL and Harrison preamps in your studio: a guide to the Revival 4000, Super 9000 and 32Classic MS.

Choosing the right preamp / channel strip is one of the most important decisions when building a professional signal path. Thanks to the latest solutions from Solid State Logic and Harrison Audio, the iconic sound known from the world's greatest recording studios, is now available in compact 1U rack formats.

Find out which of the three flagship models - the Revival 4000, Super 9000 or 32Classic MS - Will best meet your creative needs.

Legacy and history: what are tracked audio processing preamps based on?

Understanding the origins of each module allows you to better predict how they will behave in the mix. Each brings a piece of audio engineering history to the modern workflow.

SSL 4000 E - Foundation Revival 4000

Introduced in 1979, the 4000 E console revolutionized music production with its aggressive, „thumping” sound.

• Characteristics: Known for its extremely dynamic processing and expressive midrange that dominates modern rock and pop recordings.
• Iconic solutions: It was here that the '242 „Black Knob” equalizer debuted, prized for its precision and ability to dramatically shape color.
• Users: She became the choice of such champions as Chris Lord-Alge and Andy Wallace.

SSL 9000 J & K - Super 9000 Foundation

Released in the mid-1990s, the 9000 series introduced groundbreaking technology SuperAnalogue™.

• Characteristics: Offers near infinite bandwidth and unparalleled transparency (hi-fi), eliminating phase distortion.
• Capabilities: Allows for huge, deep mixes with a powerful bottom end and crystalline top end, which has made it a standard in the world of R&B, hip-hop and film music.
• Evolution: Its precision became the basis for later flagships such as Duality and Oracle.

Harrison 32 Series - Foundation 32Classic MS

Presented in 1975 by Dave Harrison in Nashville, it pioneered in-line systems.

• Characteristics: This is a „no-compromise design” console that prioritizes musicality, warmth and rich harmonic saturation.
• Unique approach: Unlike the SSL, the original 32 series had no built-in compression on the channels, relying on natural dynamics and transformer saturation.
• Legend: On these consoles Bruce Swedien shaped the sound of Michael Jackson's most important albums.

SSL Revival 4000: The aggressive character of the 1980s era.

If you're looking for the sound that defined modern rock and pop, Revival 4000 is the choice for you. This device draws directly from the heritage of consoles SL 4000 E, known for their „direct” and energetic nature.

Key features and similarities to the original:

• EQ section „Black Knob”: Uses the famous '242 circuit, offering a wider clipping and amplification range (±18 dB) and a steep high-pass filter (18 dB/octave) for precise bottom end control.
• B-Series dynamics: Revival 4000 features a unique B-series de-esser circuit based on the classic SSL Bus Compressor architecture, ideal for fast shaping of signals with excessive sibilance.
• Sound: Offers a distinctive, forward-pushing midrange and an aggressive tone that dominates the mix.

SSL Super 9000: SuperAnalogue™ precision and modern power

Super 9000 is a device for engineers who require absolute transparency, huge dynamic range (headroom) and hi-fi-like sound purity. It is a direct technological continuation of the series 9000 J & K.

Why choose it?

• SuperAnalogue™ Technology: By eliminating electrolytic capacitors from the audio path, the device offers extremely low harmonic distortion and near-zero phase shift.
• Variable Harmonic Drive (VHD): A unique feature borrowed from the flagship Duality console. Allows you to seamlessly transition from crystal clear sound to saturated sound with 2nd or 3rd harmonic dominance (tube or transistor effect).
• Dynamics and EQ: Offers the legendary speed and power of the 9000 series' dynamics section, as well as correction flexibility, allowing you to switch filter characteristics between E and G modes.

Harrison 32Classic MS: Musicianship and warmth from Nashville

For those who prefer rich, vintage sound and „analog soul.”, Harrison 32Classic MS (Mix Strip). offers an alternative to the precision of SSL. It is a return to the roots of the legendary series 32 Series, on which such masters as Bruce Swedien worked.

What sets the 32Classic MS apart?

No compression in the track: In keeping with Dave Harrison's philosophy, the device relies on natural dynamics and transformer saturation instead of aggressive VCA compression.

Preamp with Jensen transformer: Equipped with balanced JT-MB-CPCA preamplifiers that provide a full bottom end, open midrange and extremely smooth treble.

The iconic Harrison filters: A unique pair of high-pass and low-pass filters (12 dB/octave) with a characteristic resonance (3 dB) in the HPF filter, which allows for „musical” bandwidth cleaning without losing naturalness.

Comparison - which Channel Strip to choose?

Summary

Choose Revival 4000, if you need energy and impact. Bet on Super 9000, if your goal is pristine cleanliness with a modern saturation option. Reach for Harrison 32Classic MS, if you're looking for classic analog warmth and exceptional filter musicality.
