Speaker driver Impedance:
REMARKS:
Electrical Parameters are to be measured at Speaker Terminals across rated impedance Load(8ohm) with
Rated Input Signal in CD Mode setting in DBB/Loudness Off and Pre-eq at Flat unless specified otherwise.
*1) Add 10dB to the measured SNR for the final result
weighted @ Vol.max with -10dB)
*2) standard output --- 1W output with 1kHz sinewave
*3) SNR value is defined at Airplay mode, at MP3-link mode are worse a little.(SNR @ROP(A-Weighted):
limit 85dBA, @1W output (A-Weighted): limit 78dBA)
*4) Test mode : press RESET and WPS key 5s, the set go to factory mode. Many electrical parameter
should measured at factory mode.
