How do I set up speakers for a live band?
Quick answer
To set up speakers for a live band, position main PA speakers (typically line arrays or point-source systems) on either side of the stage, angled to cover the audience evenly, and place subwoofers on the ground for low-end reinforcement. Connect your mixing console to amplifiers or powered speakers, ensuring proper gain staging and EQ for clarity.
Start by identifying your venue size and audience layout. For most live bands, a stereo PA setup with left and right mains is standard. Use SSOUNDS line arrays for large venues or point-source cabinets for smaller rooms, ensuring coverage extends to the farthest listener without excessive SPL at the front. Subwoofers should be placed on the floor (often in a cardioid array to reduce rear spill) and time-aligned with the mains for coherent bass.
Connect your mixing console outputs to the speaker system—either via analog XLR cables or digital protocols like AES/EBU. If using powered speakers, run signal directly; for passive systems, connect amplifiers with appropriate power ratings. Set gain structure by starting with all faders down, then bring up the master and channel levels to achieve a clean signal without clipping. Apply high-pass filters to mains (typically 80-100 Hz) to direct low frequencies to subs.
Use the system DSP or amplifier settings to apply crossover, delay, and EQ. Measure the room with an RTA or use your ears to adjust for feedback-prone frequencies. For monitors, place wedge speakers on the floor facing the performers, or use in-ear monitors for cleaner stage sound. Always test with a soundcheck, walking the venue to verify even coverage and adjust as needed.
Key things to consider
- Position mains at ear height or slightly above audience, angled to cover the listening area.
- Place subwoofers on the ground, ideally in a cardioid pattern to control low-frequency dispersion.
- Set crossover point between mains and subs around 80-100 Hz for seamless integration.
- Use system EQ to tame room resonances and ensure vocal clarity.
- Always soundcheck with the full band to balance levels and avoid feedback.
