1 vocal mic + 2 guitar mics + 1 bass DI + 2 keyboard DIs + 4 drum mics = 10 inputs. DI boxes: 1 bass + 2 keyboard = 3. XLR: 10 inputs + 6 monitors = 16.

2 vocal mics + 2 guitar mics = 4 inputs. No DI boxes needed (using mics on acoustic amps). XLR: 4 inputs + 2 monitors = 6.

Frequently Asked Questions

Q

How many mic inputs does a typical band need?

A 5-piece rock band typically needs 12-16 mic/line inputs: 1-2 vocals, 1-2 guitar mics, 1 bass DI, 2 keyboard DIs, and 4-8 drum mics (kick, snare, 2 toms, 2 overheads, hi-hat). Add more for backing vocals or additional instruments.

  • Solo acoustic act: 2-3 inputs (vocal + guitar DI)
  • Duo/trio: 4-8 inputs
  • 5-piece rock band: 12-16 inputs
  • Full band with horns: 18-24 inputs
  • Large ensemble: 24-32+ inputs

Q

How many DI boxes do I need for a live show?

Count each instrument without its own mic: bass guitar (1 DI), keyboards (2 DIs for stereo), acoustic guitar with pickup (1 DI), laptop/backing tracks (1-2 DIs). A typical band needs 3-5 DI boxes. Passive DIs work for most; active DIs for low-output sources.

  • Bass guitar: 1 DI (passive or active)
  • Keyboard/synth: 2 DIs (stereo L/R)
  • Acoustic guitar pickup: 1 DI
  • Backing tracks: 1-2 DIs (stereo)
  • Carry spares – at least 1-2 extra
Q

How much power does a stage setup need?

A typical band stage draws 3,000-6,000 watts: monitors (200W each × 6 = 1,200W), backline amps (500W each × 3 = 1,500W), lighting (150W each × 4 = 600W), plus misc. That requires 2-3 dedicated 20A circuits at 120V (2,400W per circuit).

  • Monitor wedge: 200W each
  • Guitar/bass amp: 300-500W each
  • Lighting fixture: 100-200W each
  • 20A circuit at 120V = 2,400W max
  • Always separate audio and lighting circuits

Q

How do I estimate cable length for a stage?

Measure the diagonal of the stage and add 30% for routing around obstacles. A 24×16 ft stage has a ~29 ft diagonal, so plan for ~37 ft average cable runs. Multiply by total cable count for total footage. Always bring extra cables.

  • Average run = stage diagonal × 1.3
  • XLR cables: one per mic input + monitors
  • Instrument cables: one per guitar, bass, keyboard
  • Power cables: separate runs from audio
  • Bring 20% extra cables as spares
Q

How many monitor wedges does a band need?

Standard setup: 1 per performer position, plus 1 for drum riser. A 5-piece band typically uses 5-6 monitors. In-ear monitors (IEMs) can replace wedges. Large stages may need side-fills in addition to wedges.

  • Lead vocal: 1 dedicated wedge
  • Each instrumentalist: 1 wedge
  • Drummer: 1-2 wedges or side-fill
  • Horn section: can share 1-2 wedges
  • In-ear monitors eliminate wedge needs
