• Receiver audio set to HIBOOST = OFF and V LIMIT = OFF
• Transmitter audio INPUT set to Line+4 dBu and Level set to −9 dB
• Audio input to the transmitter: pink noise at +8.7 dBV
• Audio output at receiver: 115 dB SPL in ear with SE425 earphones (impedence at 22 Ώ)set at volume level 4.
Note: Using lower-impedance earphones or ones with different sensitivity, different battery types, and higher gain settings in the PSM system may cause
the receiver battery life to be different than specified.
Pink noise is a signal with a frequency spectrum such that the power spectral density is inversely proportional to the frequency. In pink noise, each octave
carries an equal amount of noise power.
