Amplifier Gain Setting
Test Tones
These tones are sine waves that provide a consistent, known signal for setting amplifier gain correctly. Use them with a multimeter or oscilloscope to match the output of your head unit to the input sensitivity of your amplifier. They work with any brand of amplifier. For the full gain setting procedure, see the amplifier gain setting guide or watch the gain setting video.
Before you start
Set all EQ, tone controls, bass boost, and crossover settings flat on your head unit before playing any test tone. Any head unit processing will affect the signal and result in an inaccurate gain setting.
50Hz Tones — Subwoofer Amplifiers
Use 50Hz tones when setting gain on a subwoofer amplifier or any low-pass channel.
1kHz Tones — Full Range Amplifiers
Use 1kHz tones when setting gain on a full range amplifier, 4-channel, or any high-pass channel.
Pink Noise
Pink noise contains equal energy per octave and is useful for setting overall system balance and testing frequency response.
