Item
REC-VOL = 5.0 V, REC-BAL = 2.5 V
With no signal, measure the noise using an "A"-WGT
filter. (The measured value is indicated as the relative
value compared to the full-gain level.)
REC-VOL = 5.0 V, REC-BAL = 2.5 V
With no signal, measure the DC offset voltage of the VOL
OUT pin.
REC-VOL = 5.0 V, REC-BAL = 0.0 V (1 kHz BPF)
Input a 1 kHz, +2 dBv signal and measure the attenuation
of VOL OUT 1. (Input -10 dBv and confirm that there is no
attenuation at VOL OUT 2.)
REC-VOL = 5.0 V, REC-BAL = 5.0 V (1 kHz BPF)
Input -10 dBv and confirm that there is no attenuation at
VOL OUT 1. (Input a 1 kHz, +2 dBv signal and measure
the attenuation of VOL OUT 2.)
REC-VOL = 5.0 V, REC-BAL = 2.5 V
Alternately input a 1 kHz, +2 dBv signal, and measure the
channel crosstalk. (Use a 1 kHz BPF.)
Input a 1 kHz, -10 dBv signal to the LINE IN pin and
measure the gain at the BUF OUT pin.
PB mode
Input a 1 kHz, -30 dBm signal to the DOLBY PBIN pin
and measure the output level at the LINE OUT pins.
PB mode
Input a 1 kHz signal and set the output level so that the
THD is 1%.
PB mode
Input a 1 kHz, -30 dBm signal (reference input level) and
measure the distortion. (Measure the distortion as THD + N.)
PB mode
With no signal, measure the noise using an "A"-WGT
filter. (The measured value is indicated as the relative
value compared to the reference level.)
REC mode
With no signal, measure the DC offset voltage of the LINE
OUT pin.
PB, MUTE mode
Input a 1 kHz, -18 dBm signal to the DOLBY PB IN pin
and measure the attenuation when LINE MUTE is on.
(Use a 1 kHz BPF.)
PB mode
Alternately input a 1 kHz, -18 dBm signal to the DOLBY
PB IN pin and measure the channel crosstalk. (Use a 1
kHz BPF.)
METER ON, REC mode
Input a 1 kHz, -26 dBv signal to the REC IN pin and
measure the output DC voltage at the METER pin.
