11.7 Audio Control
The Audio Control screen enables you to adjust the gain of the audio channels.
11.7.1 Gain
The Pair 1–8 sliders adjust the gain of the left and right channels of the audio pairs. The
adjustment range is -12 dB to 12 dB in 0.1 dB steps. The preset value is 0 dB.
11.7.2 Tone Frequency
The Tone Frequency slider adjusts the tone frequency. The adjustment range is 0.1 KHz to
10KHz in 0.1 KHz steps. The preset value is 1 KHz.
Points to consider:
•
Each embedded pair (EMB1/2 to EM15/16) has its own individual tone generator.
•
AES can be balanced or un-balanced (LC2000-IQ/LC4000-IQ, balanced AES only).
Only four pairs of AES can be processed.
•
Analog audio processing is limited to four pairs.
•
Analog and AES outputs are derived from Embedded pairs, hence test-tones follow
Embedded audio settings.
