Get to know them!

The Solid State Logic L550 Plus brings SSL's legendary studio-grade sound and exemplary hardware performance to live applications. Armed with next-gen Optimal Core Processing technology and I/O architecture, the L550 Plus offers incredible configuration possibilities and routing flexibility. This SSL Live console boasts a unique ergonomic design, which includes three 12-fader banks, an uncluttered control layout, and an intuitive 19-inch multi-touch screen. Want to take command of your mix remotely? No problem. SSL's TaCo tablet application makes it easy. The L550 Plus provides a comprehensive complement of local I/O, with 32 analog mic/line inputs, 32 analog line outputs, and four headphones/monitor outputs, plus AES/EBU and MADI digital I/O. You also get world-class digital conversion and an outstanding collection of built-in insert effects. A great choice for touring, house of worship, and corporate applications, the L550 Plus demonstrates SSL's untouchable legacy as an innovator of high-performance consoles.

Next-gen Optimal Core Processing (OCP) technology

Here at Sweetwater, we're astounded by the flexibility afforded by the L550 Plus's next-gen Optimal Core Processing (OCP) technology and I/O architecture. The L550 Plus supplies you with 1,136 inputs and 1,136 outputs, with 288 mix paths at 96kHz. You can assign these flexible paths as Channels, Stem Groups, Auxes, and Masters, and configure them as anything from mono (which uses a single path) to 5.1 (which uses six paths). You also get four 32-in/36-out Matrixes with dedicated processing; all output paths include highpass and lowpass filters, an SSL-flavored 4-band parametric EQ, two seconds of delay, and an all-pass filter, plus two insert points that can be used with the console's internal Effects Rack, as well as with external processors.

Take command with confidence

When you're in the heat of battle, you need a clear view of everything in your audio environment. SSL knows this. That's why the L550 Plus was designed to keep every control you need at your fingertips when you need it. The L550 Plus's uncluttered interface arranges the most commonly used functions to sit within reach where your hands naturally fall on the console. Color change technology provides instant visual feedback without causing eye fatigue. You also get three fader banks that offer lightning-fast access to the L550 Plus's 36 faders, which are complemented by a knob-per-function Channel Control Tile that's tailor-made for those who prefer the hands-on-hardware approach.

High-resolution 19-inch multi-touch screen

Thanks to its high-resolution 19-inch multi-touch screen, the L550 Plus is as intuitive to use as a smartphone. Not only can you use this touchscreen for system and I/O configuration, but you can also create surface layouts using the Layer Manager, for opening the L550 Plus's Channel View and Console Overview, and more. The Layer Manager empowers you to place any Channel, Stem Group, VCA, Aux, or Master, anywhere on the available Fader Tiles. The Channel View gives you a clear, logically organized overview and interface for your channels. Console Overview supplies an at-a-glance view of the entire console's signal flow. You also get a dedicated Automation interface and straightforward access to the console's Effects Rack.

The SSL L550 Plus includes a generous amount of local I/O.

Great-sounding complement of local I/O

The Solid State Logic L550 Plus includes a generous amount of local I/O, with the capacity to serve both front-of-house and monitoring duties. For starters, you get 32 analog mic/line inputs and 32 analog line outputs boasting SSL's renowned SuperAnalogue design for a sound reminiscent of the company's legendary studio consoles. You get four headphones/monitor outputs along with AES/EBU I/O with fully variable sample rate conversion and an array of MADI ports with redundant capabilities. There's also a separate MADI In/Out port for connecting external devices, such as Waves MultiRack or a VST effects host. SSL Blacklight II connectors, a Dante card, and a redundant pair of SSL X-Light connectors are also included, plus MIDI, LTC, Word Clock, and GP I/O. To top it off, this digital live console vaunts a frequency response within 0.05 dB of flat from 20–20kHz (within 1.3 dB down to 10Hz), a THD+N of <0.005%, and superior 24-bit/96kHz conversion.

Teeming with high-quality baked-in effects

The L550 Plus's Effects Rack is loaded with a full range of studio-quality processors accessible via the insert points on Channels, Stems, Auxes, and Masters, as well as from the router. This digital console includes seven categories of effects in mono, stereo, and multichannel formats. The L550 Plus retains the whole gamut of effects processors, including reverbs, delays, modulation effects, EQ, and even the famous SSL Stereo Bus Compressor. You also get a digital emulation of the SSL Variable Harmonic Drive (VHD) circuit, guitar and bass cabinet emulations, a Denoiser and Enhancer, a sizeable cache of metering tools, and a Dialogue Automix system. The L550 Plus's Effects Rack is designed to emulate the familiar workflow of a recording studio, and your effects routings and parameters are stored as part of the console's automation. All effects operate with ultra-low latency — an essential for live applications — and the entire Effects Rack runs off its own dedicated processing core with adaptive processing for ultimate efficiency.

The SSL L550 Plus is replete with studio-quality effects.

No interest will be charged on promo purchase balance, and equal monthly payments are required on promo purchase until it is paid in full. The payments equal the amount financed divided by the number of months in the promo period, rounded up to the next whole dollar. These payments may be higher than the payments that would be required if this purchase was a non-promo purchase. During the last month(s) of the promo period the required monthly payment may be reduced due to the prior months’ rounding. Regular account terms apply to non-promo purchases. New Accounts as of 07/31/2025: Purchase APR is 34.99%. Penalty APR is 39.99%. Min Interest Charge is $2. Existing cardholders: See your credit card agreement terms. Subject to credit approval.

The estimated required monthly payment shown which excludes taxes and delivery equals the amount financed divided by the number of months in the promo period, rounded up to the next cent. During the last month(s) of the promo period the required monthly payment may be reduced due to this rounding. These payments apply only with the financing offer shown. If you make these payments by the due date each month, you should pay off this amount financed within the promo period, if it is the only balance you are paying off.
