SSL Super 9000 and Revival 4000: two icons, two sound philosophies
- Two professional channel strips signed Solid State Logic
- A non-competitive but complementary comparison
- Focus on technical and tonal characteristics
- Choice support based on your workflow
Solid State Logic Super 9000 Channel Strip
This model is designed for those who want the "modern" SSL sound, with SuperAnalogue™ technology that the company describes as ultra-low distortion, wide bandwidth, transparency. It is a 1U channel strip with mic/line preamp, compressor/gate, EQ, filters, flexible routing.


Key Features.
- Dual mic preamp with choice of SuperAnalogue™ (transparent) or VHD™ (Variable Harmonic Drive) mode for saturation
- VCA compressor with THAT 2181A chip, Fast Attack mode, Peak Detect mode
- 4-band EQ: 292 "Pink Knob" mode (variable Q) or 242 "Black Knob" mode (constant Q)
- High-Pass filters 18 dB/oct and Low-Pass filters 12 dB/oct
- Balanced insert, external sidechain, stereo link, customizable routing
Sound and context of use
Very clean, defined, open sound: great for modern contexts where transparency and maximum quality are required. VHD option allows you to add saturation or color (second and third harmonics) if you need more character.

When to consider it
- Modern productions: pop, R&B, electronic
- Professional-level recording and mixing
- Maximum versatility between cleanliness and color
Solid State Logic Revival 4000 Channel Strip
This model is dedicated to lovers of the "historic" SSL sound: the 4000 series that made recording history in the 1980s is revived in 1U rack format.


Key Features.
- Jensen JT-115K-E transformer mic preamp
- One-knob de-esser with 7 kHz side-chain
- Discrete Class A VCA compressor/gate, soft/hard knee, Fast Attack
- 4-band EQ: Brown Knob 02 and Black Knob 242 modes
- HPF/LPF filters according to mode
- Balanced insert, external sidechain, flexible process-order, stereo link
Sound and context of use
The focus is on character, on the "classic" SSL sound signature. If you're looking for vintage SSL grit, it's a good choice. More musical and colorful than the Super 9000, thanks to the original transformer and circuitry.
When to consider it
- Rock productions, 80s/90s style pop
- Sound with identity and sonic signature
- Color-oriented analog setup
