Adjusting Analog and Digital Audio Levels
Gain on Input 1 can be configured for mic, unbalanced or line level sources. Input 2 accepts line level only.
To adjust input audio levels, click on the input slider and drag it to the desired input gain level. Alternatively, click the arrows below a PPM meter to incrementally increase or decrease the input level in 0.5dB steps. Input levels on the Input panel should be set to ensure audio peaks average at the first yellow indications on the PPM meters, which represents nominal 0 VU at -18dBFS. Audio levels should also be verified using the meters in the PPMs panel.
Input attenuation is available when the input type is AES digital, however there is no additional gain.
Changing the Input PPM Meter Scale from dBFS to dBU
It is also possible to switch the input PPM meter scale from dBFS (default) to dBU:
1.Open the HTML5 Toolbox Web-GUI and click Settings in the Menu Bar, then click Options to display the Options panel.
2.Click the Analog Inputs PPM Scale drop-down menu and select dBU.
3.Click Save to change the setting.
