"Wow, what an impact the CL-12 made on my workflow from the moment it arrived on set. It was as if the 688 blossomed before my eyes coming into its full potential. Simply put...Everything is better."

Thom Shafer, Production Sound Mixer

Linear Fader Controller for the 6-Series Mixer/Recorder Line

In the fast-paced production landscape, the CL-12 linear fader controller meets a growing demand from production professionals who must make quick transitions between cart and over-the-shoulder applications. The optional accessory significantly expands the mixing capability of the 6-Series mixer/recorder line. The CL-12 attaches directly to any 6-Series mixer with minimal cables, making transitions between cart-based setups and over-the-shoulder workflows quick and easy.

The CL-12 is compatible with the 688, the 664 and the 633. With the CL-12, the 688 gains a 3-band parametric equalizer for each of its 12 inputs, shortcut access to SuperSlot™ wireless receiver data (when used with the SL-6), and MixAssist™ and Dugan automix monitoring. Not all features on the CL-12 are available with every 6-Series mixer/recorder. For more information, view the CL-12 Feature Comparison Chart.

The CL-12 also includes ports for a USB keyboard connection for efficient metadata entry, and for powering an optional USB lamp.

Beautiful Form & Function

The CL-12 comes in two models. The standard CL-12 is designed to be a sleek and durable mixing surface with robust black aluminum side panels. Tactile controls, including illuminated buttons and twelve easy-to-use manual faders, combine with LED metering to improve the whole mixing experience.

In addition to offering everything the standard CL-12 does, the CL-12 Alaia also features incredibly smooth gliding Penny & Giles faders — the best in the industry. Gorgeous custom hardwood side panels also enhance the look of the CL-12 Alaia. Available in either Blonde Maple or Red Mahogany, the panels are handmade by Amish craftsmen specifically for Sound Devices, LLC. The CL-12 Alaia also comes with a pair of black aluminum side panels.

The CL-12 Alaia (pronounced "ah-LIE-ah") is named after the historic, hand-carved wooden surfboards ridden globally pre-20th century, with a recent resurgence in popularity in the early 2000s. The finless longboards were renowned for their flawless design, durability, and longevity.

Dedicated Tactile Controls

The CL-12 features large, backlit transport buttons for record and stop, as well as numerous dedicated buttons for fast access to menus and other key functionality, such as track arming, naming, and routing. Metadata entry is a button press away, and there are buttons for PFL, HPF, phase inversion, COMs and RTNs. There are even three user-definable buttons for flexible customization.

Headphone Monitoring

A 1/4-inch to 1/4-inch headphone cable is also provided to allow monitoring from the CL-12, plus it adds a low-resistance ground connection, giving extra robustness to the mixer/controller combo in the presence of static shock. The CL-12 also contains an 1/8-inch (3.5 mm) port on the front panel.


A USB A-to-B cable provides both power and control. Sound Devices recommends always using the supplied USB cable and 1/4-inch headphone cable for optimum CL-12 performance. Although optional for the 688, a micro USB power cord (not provided with the CL-12) is required as a DC Power Boost for CL-12 integration with the 664 and 633.
