About the MIX bus types (VARI / FIXED) • About word clock • Conventions in this manual • About the firmware version About the MIX bus types (VARI / FIXED) The sixteen MIX buses provided on the LS9 can be assigned either as VARI or FIXED types in pairs of adjacent odd-numbered/even-numbered buses (→ p. 213). They can also be switched between monaural/stereo for the same pairs of buses. VARI type and FIXED type buses differ as follows. ● VARI This type allows the send level of the signal sent from the input channels to the MIX bus to be varied. The point at which the signal is sent from the input channel to a VARI type MIX bus can be chosen from before the EQ (attenuator), before the fader, or after the [ON] key. This type is used mainly for sending the signal to a monitor system or external effect. ● FIXED With this type, the send level of the signal sent from the input channels to the MIX bus is fixed. The signal from an input channel is sent to a FIXED type MIX bus from before Pan (if the MIX bus is monaural) or after Pan (if the MIX bus is stereo). This type is used mainly when you want to distribute signals to an external device with the same mix as the STEREO/MONO buses. About word clock "Word clock" refers to the clock that provides the basis of timing for digital audio signal processing. Normally, one device transmits a reference word clock signal, and the other devices receive this word clock signal and synchronize to it. In order to transmit or receive digital audio signals to or from an external device via the LS9's 2TR IN DIGITAL/2TR OUT DIGITAL jacks or via a digital I/O card installed in a slot, the word clock must be synchronized between the devices. Be aware that if the word clock is not synchronized, the signal will not be sent correctly, or there may be unpleasant noise. (For details on synchronizing the LS9's word clock with an external device → p. 46) Conventions in this manual In this manual, switch-type controllers on the panel are called "keys." Of the control knobs on the panel, those that turn from a minimum value to a maximum value are called "controls," while those that turn endlessly are called "encoders." Controllers located on the panel are enclosed in square brackets [ ] (e.g., [CUE] key) in order to distinguish them from the virtual buttons and knobs displayed in the screen. For some controllers, the name of the section is given before the [ ] (e.g., LAYER [MASTER] key). Whenever there is a difference between the LS9-16 model and the LS9-32 model, specifications that apply only to the LS9-32 model are enclosed in curly brackets { } (e.g., INPUT jacks 1-16 {1-32}). About the firmware version You can view the firmware version number in the MISC SETUP screen (→ p. 206). You can also download the most recent firmware version from the website. http://www.yamahaproaudio.com/ 14 LS9-16/32 Owner's Manual
