Short Description:

SSL channel strip processing in 500 Series format. In Used, Excellent condition

What We Think:

The SSL SiX Channel 500 Series module is one of those rare pieces of gear that perfectly captures what engineers love about SSL: clean, punchy signal paths, musical processing, and a workflow that gets great sounds quickly. By bringing the channel strip architecture from SSL's acclaimed SiX console into a single-width 500 Series format, the SiX CH delivers an impressive amount of functionality without sacrificing the sonic quality that has made SSL a studio staple for decades.

At SoundPure, we're particularly impressed by the versatility packed into such a compact module. The SuperAnalogue mic preamp is exceptionally clean and detailed, offering plenty of gain and headroom while maintaining the fast transient response and low-noise performance SSL is known for. Whether you're tracking vocals, acoustic instruments, drums, bass, or electric guitar, the SiX CH provides a polished, professional front end that feels equally at home in project and commercial studios.

The EQ section is deceptively simple but highly effective. Borrowing from classic SSL design philosophy, the two-band EQ excels at broad, musical tone shaping, while the switchable bell modes provide additional flexibility when more targeted adjustments are needed. Add in the one-knob compressor—which delivers surprisingly smooth and musical control over dynamics—and you've got a complete channel strip that encourages fast decisions and great-sounding recordings.

For engineers looking to add authentic SSL character and workflow to a 500 Series rack, the SiX CH represents tremendous value. It's not about endless options or complicated controls—it's about getting professional results quickly and confidently. That's exactly the kind of gear we love: tools that stay out of the way and help you focus on making great recordings.

Manufacturer Description:

Deceptively simply, extremely effective 

SiX Channel Strip (SiX CH) is a single-width 500 Series channel strip using the SuperAnalogueTM channel processing features from SSL’s SiX console including the Mic-pre, low and high frequency EQ, as well as the single knob compressor.

Features:

• SSL SuperAnalogueTM  mic pre
• +48V phantom power
• Phase invert switch
• 5 segment LED meter in dBu
• Switched 12 dB/oct, 75 Hz High Pass Filter (HPF)
• Classic SSL HF and LF EQ
• Switch from shelf to bell curve
• Single knob Channel Compressor with variable Threshold.
• Front Panel TRS Line Input with 1MΩ Hi-Z switch.
• Dedicated output Trim

SuperAnalogue 

Using the same technology as SiX and large-format SSL consoles, SiX CH features a SuperAnalogueTM mic pre, offering wide gain range and ultra-low noise. It’s clean, fast and punchy - the perfect preamplifier for any source material.

SSL HF and LF EQ

SiX CH EQ is a classic SSL style gentle, broad stroke two-band design with high and low shelving filters at 3.5 kHz and 60 Hz, +/-15 dB gain range. Each band can be independently switched between shelving and bell curves. The bell curves change centre frequency to operate at 5 kHz and 200 Hz giving greater versatility from the two controls.

Channel compressor 

A ‘one knob’ channel compressor with features that give powerful and versatile performance from its deceptively simple controls. Using the tried and tested SSL feed-forward circuit design, program-dependant attack time and automatic make-up gain to maintain signal level.

TRS Line Input 

The front facing TRS line input offers a convenient way to add instruments on the fly or use SiX CH as a feature packed summing module. 10 kΩ nominal Line Input impedance can be changed to 1 MΩ via the Hi-Z switch. The 1MΩ impedance makes this input suitable for very high impedance sources such as passive guitar pickups without the need for an external DI box.
