Bass And Treble Control; Voicelift Level Adjustment - Extron electronics PVS 407D User Manual

Bass and Treble Control

For optimum audio quality, the audio input levels and the bass and treble controls must all
be set up properly. Input audio levels may need to be adjusted depending on the variation
of the output levels from different source devices.
NOTE: By default these levels are set for the consumer product level of -10 dBV.
Bass and treble should be adjusted once the input and output levels have been adjusted.
These are adjusted by configuration software only, with a range from -24 dB to +12 dB.
By default the bass and treble have been set at 0 dB.

VoiceLift Level Adjustment

To adjust VoiceLift microphone levels, press the VoiceLift adjustment buttons (in 1 dB
steps) from -18 dB to +24 dB, default is 0 dB.
While speaking into the microphone, increase the gain until the Normal LED is lit and the
Peak LED only lights occasionally.
INPUT
Figure 11.
The VoiceLift microphone receiver input signal is not affected by the system volume
adjustment and tone control via SIS or an MLC controller attached to the switcher. The
VoiceLift audio channel is always active, and it is independent of the selectable audio
inputs (1 to 7).
The VoiceLift microphone receiver input audio can be heard throughout a presentation,
whether or not audio from the selected input (1 to 6) is active or muted.
NOTE: The 1Z SIS command mutes all embedded audio on the HDMI, line out and
amplifier outputs.
The VoiceLift microphone input can be muted via a separate SIS command (see
