3.17.7 Maximum Audio Card Output
The monitor audio amplifier shall accept a maximum input voltage of 1.5 Vrms and
meet the following requirements at the maximum monitor volume setting:
1. The ratings of the audio amplifier may not be exceeded.
2. The ratings of the speakers may not be exceeded.
3. There must not be any clipping of the audio amplifier output signal.
Voltage dividers may be used to reduce the input signal level.
3.17.8 Monitor Audio Amplifier Input Impedance
The monitor audio amplifier shall have minimum 10K Ohm AC input impedance
VISUAL CHARACTERISTICS
Test conditions
Unless otherwise specified, this specification is defined
under the following conditions.
(1) Input signal : As defined in 3.3,
follow panel resolution
, signal sources must have 75 ohm
output impedance.
(2) Luminance setting : controls to be set to
250 nits(except 166V3 220 nits)
with full screen 100 %
duty cycle white signal
(3) Warm up: more than 30 minutes after power on with signal supplied.
(4) Ambient light: 400 -- 600 lux.
(5) Ambient temperature: 20 ± 5
C
Brightness
Follow Panel specification.
Color temperature adjustment
There are three factory preset white color 9300K, 6500K, sRGB.
Apply full white pattern, with brightness in 100 % position and the contrast control at 50 % position.
