An overview of the QL series I/O card and processing card expansion The rear panel provides two slots in which separately sold mini-YGDAI cards can be installed. You can add inputs and outputs by installing AD cards, DA cards, or digital I/O cards in these slots. You can also expand processing or effects by installing a DSP card. Cascade connections in the digital domain You can cascade a second QL series unit or another digital mixer, such as the Yamaha CL series, M7CL, PM5D or LS9, connected via a digital I/O card installed in a slot or a Dante connector. (Cascade connections via a Dante connector are possible only between QL series consoles.) You can cascade any of the MIX, MATRIX, STEREO (L/R), MONO, and CUE (L/R) buses. Recorder function useful for sound checks and mix recording The QL series features a USB memory recorder function that enables you to record output from STEREO or MIX buses onto a USB flash drive. It also enables you to play audio files that reside on a USB flash drive by assigning the files to input channels or monitor outputs. The MP3 format (MPEG-1 Audio Layer-3) is supported for recording. For playback, MP3, WMA (Windows Media Audio), and MPEG-4 AAC (Advanced Audio Coding) formats are supported. This function can be useful if you want to record certain bus mix outputs or play music for a sound check through speakers. Security functions at user or system level Functionality can be restricted for users other than the administrator at three levels of security: administrator, guest, and user. Passwords can be specified for the administrator and for users to help prevent important settings from being changed accidentally. Information specific to each user (user level, system settings, and user-defined key/knob settings) can be stored on the unit or on a USB flash drive as a "user authentication key." By loading your own user authentication key, you can instantly reconfigure the unit for your own ideal operating environment. Help file downloadable to the unit You can download from the website a Help file that explains the parameters and messages displayed on the screen. Once you load the Help file, it will be stored inside the unit so that you can use the Help function at any time. About the models The QL series is available in two models: QL5 and QL1.
