AV-4300 AV-5000 2.4.3 Stadium Surround Check
Ad justment Procedure 1. Set to SURROUND : STADIUM " Check that the following waveforms are obtained (Input signal (1) and (2)). " Front : Chec k that the phas es of R and L are different and 400Hz is superimposed on 5kHz. The amplitudes of R and L are different. " Rear : Check that the phas es of R and L are opposite and 400Hz is superimpos ed on 5kHz. The amplitudes of R and L are different.
2.4.6 Concert Hall Surround / Monaural Check
Ad justment Procedure " Check that the following waveforms are obtained (Input signal (1) only).
" Front: The phas es of R and L are different. The amplitudes
are different.
" Rear: The phas es of R and L are opposite. The amplitudes
of R and L are equal.
No te: The monaural check c an be omitted. Amplitude levels of front R and L are not even depending on the P.W.B. Center has no output. Note: Center has no output.
