Appendix

Glossary

MIX

MIX refers to the stereo output signals which flow in the device. The input signals to the device flow to each MIX. You can assign any MIX to any analog output jack or any digital output jack.

VST Plug-in

VST (Virtual Studio Technology) is a technology developed by Steinberg which allows the integration of virtual effect processors and instruments into your digital audio environment. VST Plug-ins are instrument- and effect-based software of VST format. When you install a VST Plug-in to your computer, it will work on any DAW software compatible with VST Plug-ins, such as Cubase series.

DAW (Digital Audio Workstation)

DAW is an integrative system of music production, which lets you record and edit digital audio data. DAW software programs are applications which allow you to build such comprehensive systems on a computer.

Word Clock

Word clock synchronizes the process timing of audio signals when transferring digital audio data between multiple devices. Normally, one device transmits a reference word clock signal, and the other devices receive this word clock signal and synchronize to it. If the word clock signal is not transferred correctly, click noise may occur or recording may not be successful, even if the sample rates of the various devices are set to the same value.

Buffer Size

Buffer size refers to the amount of memory used to temporarily hold data during playback and recording. It is recommended to adjust the buffer size depending on the situation. Normally, a higher buffer size reduces load to the computer CPU but produces latency (time lag). Smaller buffer sizes reduce latency but produce greater load to the computer CPU. This high load to the computer CPU may result in noise or the sound cutting off.

Scene

A Scene is stored data which maintains the settings on the Main window of dspMixFx UR28M. You can recall the stored Scene in dspMixFx UR28M, and up to 20 Scenes can be stored.

Settings file of the dspMixFx UR28M

The settings file of the dspMixFx UR28M is a data file including up to 20 scenes which can be saved to your computer. You can load the dspMixFx UR28M settings file to the dspMixFx UR28M.

Sweet Spot Data

Sweet Spot Data are preset settings data of the Sweet Spot Morphing Channel Strip created by top-class engineers. This data includes the settings for the compressor and equalizer which are saved to each five points around the MORPH knob.

Side Chain Filter

The side chain filter is a peaking filter which adjusts the frequency range to which the compressor is applied. It features Q (band width), F (center frequency), and G (gain) parameters. For example, if the compressor reduces the audio signal level excessively because only the specified frequency of the audio signal is at a high level (and other frequencies are lower), you can selectively lower the level of the specified frequency by using this peaking filter. This will prevent the compressor from excessive level reduction.
