What is an input list?
An input list names the audio sources that need connections to the sound system. It usually identifies channels and whether each source uses a microphone or direct connection through a DI.
Yamaha recommends including the source name, mixer channel and microphone or DI information. Source location and monitoring requirements can provide additional context.
A fictional five-channel acoustic trio
This example pairs with the trio stage plot: a vocalist, acoustic guitarist and keyboard player. Channel numbers are proposed source numbers; confirm the final venue patch with the engineer.
1 | Lead vocal | Vocal microphone | Straight stand | Center front.
2 | Acoustic guitar | DI | No mic stand | Stage right.
3 | Guitarist vocal | Vocal microphone | Boom stand | Stage right.
4 | Keyboard left | DI | No mic stand | Stage left.
5 | Keyboard right | DI | No mic stand | Stage left.
Count signals rather than instruments
The keyboard occupies one position on the plot but uses two channels in this stereo example. If the musician adds a second keyboard or playback output, update the source list rather than assuming the existing channels cover it.
Likewise, identify backing vocals separately from an instrument. The engineer should not have to infer a microphone from the name of a performer.
Resolve the connection details
Specify known microphone or DI requirements and discuss acceptable substitutions.
Confirm which side supplies microphones, DIs, stands and source cables.
Identify connection or phantom-power requirements with the engineer; do not apply phantom power indiscriminately.
List monitor feeds separately so output requirements are not confused with input channels.
Flag playback, talkback or click feeds and explicitly agree where each may be routed.
Match the paperwork to the actual show
Use identical names and revision dates on the plot and source list. After the advance, record any venue-specific channel changes where the audio team will see them. A proposed input list helps prepare the system; it does not replace checking each signal during setup.
