SSL Fusion (#1)

What is the SSL Fusion, and what does it do?

The SSL Fusion is an all-analog 2U stereo outboard processor that adds tone, weight, and space to your mix bus or stereo stems. It packs six analog coloration circuits into one box – Vintage Drive, Violet EQ, HF Compressor, Stereo Image, a custom transformer, and a 3rd-order high-pass filter. Designed by Solid State Logic for the modern hybrid studio, it delivers the warmth and finesse only real analog circuits can provide. Through Access Analog you control the actual hardware straight from your DAW.

What is the SSL Fusion best for?

The SSL Fusion is best for mix bus and mastering processing, where it adds analog color, glue, and dimension to a finished mix. Engineers reach for it to thicken and widen a stereo mix, tame harsh top end, and add transformer weight at the end of the chain. It also shines on stems and individual sources – drums, bass, guitars, and synths all take well to its saturation and stereo tools. It’s a finishing box built to make an in-the-box mix feel more analog.

Is this the real SSL Fusion hardware, or an emulation?

This is the actual SSL Fusion hardware – real analog circuits, transformers, and saturation, not a model of them. Real Gear. No Emulations. Access Analog’s Analog Matrix plugin connects your DAW to a physical, robotically controlled Fusion and streams your audio through it in real time. You hear the genuine unit, the same box engineers rack in professional studios.

How much does it cost to use the SSL Fusion at Access Analog?

The SSL Fusion reserves from $4.09 at Access Analog, and you can also use it on demand with credits or an active subscription. There’s no need to buy the hardware, you only pay for the time you actually process audio through it. New accounts get a free hour (about 12 free credits) to try real gear before committing. Reserve a session from the calendar, or jump straight in on demand through the Analog Matrix plugin.

What are the six analog circuits in the SSL Fusion?

The SSL Fusion has six analog coloration circuits, each with its own bypass so you can use them alone or in combination. In signal order they are: a 3rd-order High-Pass Filter, Vintage Drive (nonlinear harmonic saturation), Violet EQ (gentle high/low shelving), HF Compressor (tames top-end harshness like tape), Stereo Image (true Mid/Side width and depth), and a custom Transformer circuit for low-end weight and high-end sparkle. There’s also a switchable insert point for patching in extra hardware, such as an SSL bus compressor. Centre-detented input and output trim controls keep your gain staging clean across all of it.

Where should the SSL Fusion go in my mix bus or mastering chain?

The SSL Fusion is most often placed near the end of the chain, as a finishing stage on your mix bus or master before any final limiting. Its job is to add the last layer of analog color, glue, and width once your balance and dynamics are already set. Many engineers run it after their main bus compressor and use the Fusion’s insert point to patch that compressor in. As always, trust your ears, the best placement depends on the material.

Is the SSL Fusion good for mastering?

Yes. The SSL Fusion is widely used as a mastering and mix bus tool, and SSL designed it specifically for that role. Mastering engineers praise the Vintage Drive and HF Compressor for adding subtle harmonic richness and smoothing harsh highs without dulling the mix. Its true Mid/Side Stereo Image is regarded as clean and musical, widening a master while keeping mono compatibility intact. It’s a “stereo analog color” finisher made for the end of the chain.

What is harmonic saturation, and how does the Fusion’s Vintage Drive create it?

Harmonic saturation is the musical distortion analog gear adds when a signal is gently overdriven, generating extra harmonics that make audio sound warmer, fuller, and more cohesive. The Fusion’s Vintage Drive is a nonlinear saturation circuit with two controls: Drive sets the amount, and Density changes the character from subtle to aggressive. A tri-color LED shows how hard you’re pushing it – green for mild, orange for moderate, red for heavy. Use a little for analog glue on a mix bus, or push it harder for grit and weight on drums and bass.

Can I save and recall my SSL Fusion settings through Access Analog?

Yes. Access Analog gives you full recall of your Fusion settings inside your DAW session, so your analog chain comes back exactly as you left it. The Analog Matrix plugin lets you save custom presets for the Fusion and automate its parameters like any other plugin. Because you’re processing line-level audio from your DAW, the Fusion works as a stereo insert or true Mid/Side processor on your mix bus or stems.
