3.2 Calibrating Using 85 dB SPL "Standard" Reference
You should calibrate the right and left monitors independently to ensure
that both monitors are set to the same acoustic level. This will ensure that your
stereo mixes are balanced and will translate well across different speaker
systems.
The goal of this Standard Reference Calibration is to ensure that when the
output meters in your DAW or mixer register 0 dB, the SPL at your mix position
is 85 dB.
你应该独立地校准右边和左边的监听器，以确保两个监听器被设置为相同的声
学水平。这将确保你的立体声混音是平衡的，并能在不同的扬声器系统中很好
地转换。
这个标准参考校准的目标是确保当你的DAW或调音台的输出表记录到0dB时，
你的混音位置的声压级是85dB。
1. Connectthe main outputs of youraudio sourceto your studiomonitors.
The left output should be connected to the speaker on your left. The
right output should be connected to the speaker on your right.
2. Beginbyturning theinput sensitivityofyour Eris XTmonitorstothelowest
setting.
3. Turntheoutputofyouraudiosource(audiointerface,mixer,orspeaker-
management device) to its lowest setting.
Note: If you have any outboard processors (EQs, limiter, etc.) connected between the
audio source and your monitors, disconnect or bypass them. If your audio source is a
mixer, make sure that it is zeroed out.
4. Play20 Hz to 20kHz full-bandwidth pink noiseat 0dB through the outputs of
your primary audio source.
5. Turnup the outputs of your primary audio sourceto the unity gain setting."Unity
gain"is the setting at which the signal level is neither boosted nor attenuated.It
is usually marked by a"0"or a"U"on the audio device's level fader or knob. In
many digital interfaces and digital devices, the device's maximum level is also its
unity gain setting. Please consult your audio device's user's manual or the
manufacturer'sWebsiteformoreinformationonitslevelsandadjustments.You
should not hear the pink noise. If you do, repeat step 2.
6. While measuring the output level with an SPL meter, begin slowly increasing the
input sensitivity (volume)of your left speaker until the acoustic level of the test
tone playing reaches 82 dB SPL. When both speakers play simultaneously, the
overall SPL will increase by about +3 dB (85 dB).
7. Power down your left speaker.
8. Slowly increase the input sensitivity (volume) of your right speaker
untiltheacousticlevelofthetesttoneplayingreaches82dBSPL.
