Part 2 Complete.

Part 3

Purpose: To introduce the Yamaha O1V96v2 Digital board and the function of Scene Memory within the Sound Booth.

Set up for lab:
           
Note: The following pin patch is needed:

MD (113,114) to AD 1 (169) & AD 2 (170)
CD (111,112) to AD 3 (171) & AD 4 (172)
Omni out (###, ###) to MD in (###, ###)

Note: a patch schedule is taped to the back wall of the Main-stage sound booth

Each person in class will need two different sources.
Each person will need two presets in the Scene Memory starting @ scene #20

Scene memory assignments:

Please use these preset numbers so class projects do not interfere with sound design for Dear Finder.

Useful Vocabulary when using the Yamaha O1V96v2:

AD- Analog to Digital Converter inputs (12 XLR and 16 1/4” inputs on )
ADAT - Optical connection capable of sending 8 channels of 24 bit 96 kHz audio
Word Clock – Synchronizes internal clocks (Sample rate) of all devices connected 
Slot – Back expansion bay on the O1V96V2 (Connects to Layla outputs and Amp EQ inputs)
MIDI – Versatile protocol allowing communications with all other MIDI enabled devices
Layer - Determines what the faders are assigned to.
Fader Mode – Similar to layers but simulates AUX output knobs with the 16 Faders
I/O – Input/Output
Home – Wonderful button that will bring you back to I/O Meters in display
Scene- Saved board settings that can be recalled

Useful info:

The input procedures for a digital board are no different from an analog board.  The functions of Gain and Pad all operate as if on an analogue board.  All other functions from an analog board can be found in a condensed version on the O1V96v2.  For example, there is only one area to access the digital equalizer settings for all 32 inputs and 16 outputs.  The Select button above each channel determines what channel will be affected. 

Troubleshooting
The key for troubleshooting on a digital board is being able to follow signal flow.  A basic signal routing display can be found by repeatedly pressing the Home button.  While the display can seem cryptic it can show internal components that would normally be multiple send/return devices for an analog board.  Use the Home meter display to see how far signal is progressing through the board.  The output display can be found by switching layers while in the home screen. 

Words in Italics are buttons to push.
