Important Note: 15 volt phantom power can only be supplied on the Auxiliary input; this

Adjusting Audio Levels
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.
Important Notes: There is a maximum of 6dB of additional gain available when adjusting a
digital input.
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
2. Click the Analog Inputs PPM Scale drop-down menu and select dBU.
3. Click Save to confirm the new setting.
