Appliance Input Impedance:
0.5-V Setting:
Greater than 400 Ohms, or equivalent to less than
1/1000 W (0.001 W or 1 mW) load
25-V Setting:
Greater than 20 kOhms, or equivalent to less than
1/32 W (0.03125 W or 31.25 mW) load
Sound pressure level measurements were made at 16 VDC with audio inputs of 0.5 V RMS in the 0.5-V setting and with 25 V RMS
in the 25-V setting. Current measurements were made at 33 VDC with audio inputs of 0.5 V RMS in the 0.5-V setting and with
25 V RMS in the 25-V setting.
Reverberant dBA is a minimum UL rating based on sound measurements in a reverberant test room.
