Music Glossary: live-sound category

Send stage plots, input lists, RF plan, and rider notes well before load-in. more

Sends per channel to monitors or FX; pre-fader for monitors, post-fader for time-based FX. more

Set preamps for healthy headroom; use PFL and reference tones to normalize channels. more

Primary/secondary networks with proper switch QoS; clocking sanity checks. more

Control groups to adjust multiple channels' levels together without altering individual faders. more

Secondary speakers time-aligned for coverage further from the main PA. more

Calculate delay by distance; aim fills to cover dead zones without smear. more

Stored snapshots of console state for fast recall per song or act. more

Plan for console crash: analog fallback, spare DI/mics, and minimal rig to keep show running. more

Main audience sound system and engineer position mixing the show. more

Clear responsibility split; comms between engineers; snapshot management. more

Max usable level before feedback occurs; improved with mic choice, placement, EQ, and pattern control. more

Graphic: fixed bands for quick cuts; Parametric: variable freq/Q/gain for precise control. more

Switch that disconnects audio ground on a DI to break loops and reduce hum safely. more

Musicians/crew should use molded plugs or IEMs responsibly; OSHA/venue limits apply. more

Apply HPF broadly to non-bass sources to clear low-end mud and improve headroom. more

Lift grounds safely, check DI isolation, swap cables; trace from source to bus. more

Personal monitor systems isolating stage sound; reduce bleed and protect hearing. more

Ambient mics, pan for space, and careful limiter to combat occlusion/isolation. more

Channel-by-channel list (source, mic/DI, stand, phantom) for patching and gain staging. more

Round‑trip delay through converters/network/plugins; minimize for IEMs and time alignment. more

Quick signal check for every input before soundcheck to verify patching and basic function. more

Teach performers proximity/axis for consistent tone and feedback control. more

Engineer and system handling on-stage mixes: wedges and IEMs. more

Use +48V only where needed; mute before enabling; beware ribbon mics and bad cables. more

Isolated power, proper distro, and star grounding reduce hum and hazards. more

Safe, isolated power to audio/lighting; avoid ground loops; adequate amperage; GFCI where required. more
