Speaker & Amplifier Calibration

Initializing...

Measurement

Small to mid-size nearfield studio monitors (5-7 inch woofer)

Frequency Range: 50 - 12,000 Hz
Gain Limits: ±12 dB
Max Dip Correction: -12 dB

Limit the number of EQ corrections. Fewer bands = simpler corrections. More bands = more precise tuning.

Instructions:

  1. Connect your phone to the amplifier via Bluetooth or cable
  2. Position a microphone at your listening position
  3. Click "Start Measurement" to run a frequency sweep
  4. The app will analyze the response and suggest EQ settings

Note: AirPlay and Bluetooth introduce latency (typically 100-200ms for Bluetooth, up to 3 seconds for AirPlay). The app automatically detects and compensates for this delay. Check the console (F12) to see detected delay and alignment quality.
