Headphone Output Power into 32 Ohms
This rating states continuous headphone output power per channel into a 32-ohm load.
Power is expressed in milliwatts or watts; 1,000 mW equals 1 W. The load, output socket and distortion limit belong to the rating and should remain attached to the number.
Headphone Output Power into 32 Ohms — Headphone Amp
For a headphone amplifier, the 32-ohm rating describes its electrical output under that load condition. Low-impedance loads can demand substantial current from the output stage. Headphone sensitivity is also needed to relate electrical power to acoustic level.
Compare continuous per-channel figures at 32 ohms using the same output type and similar test frequency and distortion limits. Do not substitute a rating at another impedance or add two channel ratings into one. Peak or burst output is a different measurement.
Headphone Output Power into 32 Ohms — Digital Audio Player
For a portable player, this figure describes the built-in headphone amplifier driving a 32-ohm load. Keep the selected socket and any high-power or gain mode with the value; different operating modes can have different limits.
Compare per-channel continuous power at 32 ohms under similar distortion and test-frequency conditions. A balanced-output rating should not be applied to the single-ended socket. Headphone sensitivity also affects achievable level, so impedance alone does not determine whether the player has enough output for a particular headphone.
