Sound Devices has expanded support for its CL-12 Linear Fader Controller with the release of Firmware Version 2.11, which offers compatibility to both the 664 and 633 Field Production Mixers. Initially introduced only for the 688 mixer/recorder, the CL-12 is an optional accessory that features smooth-gliding 100 millimeter linear faders and is ideal for live mixing of multiple audio signals.

In addition to CL-12 support, firmware v2.11 brings several new features to the 664 and 633 mixer/recorders, one of which is QR Codes for quick smartphone access to important online documentation, such as an approved media list and the user guide for that product. It also offers a new User Bits mode that allows jamming of external timecode user bits. With the CL-12, the 664 and 633 gain sunlight-viewable, 22-segment LED metering, plus seven-segment PFL metering with limiter activity and also offers three user-programmable buttons as well as numerous dedicated back-lit buttons for quick access to key functionalities; such as metadata entry, transport controls, track arming, routing and more.

When working with the CL-12, the 664 has a 54dB linear fader range across 12 linear faders, High Pass Filter control on channels 7-12, and Input Phase control on channels 2, 4 and 6. When attached to a CL-12, the 633 has a full 96dB linear fader range available across six linear faders, High Pass Filter control on all channels, and Input Phase control on channel 2. The CL-12 also includes two additional USB ports — one for a USB keyboard connection for efficient metadata entry, and one for powering an optional USB lamp. The CL-12 comes in two models: the standard CL-12, with aluminum sides, and the CL-12 Alaia. The CL-12 Alaia features smooth-gliding Penny & Giles faders and custom hardwood side panels in either Blonde Maple or Red Mahogany.
