Changing Channel Properties - Mic/Line Input AEC (CP2)
You can use channel properties to modify a Mic/Line Input AEC channel.
You can make any of the following changes:
Feature Description
Active (Group only) Lets you choose which member of the group to show or modify.
Sync All (Group only) Lets you synchronize all the members of the group to match the settings
of the active member.
Source If digital (Dante or DIALOG
®
20 Mic) channels are available in the
partition, you can choose them as digital sources from this drop-down
list.
Sig Gen Lets you turn on the signal generator for this channel and change the
signal generator settings.
Phantom Power Phantom power is an auxiliary power source used to power certain types
of microphones. Phantom power voltage is 24VDC. Default is On.
Coarse Gain The Coarse Gain slider adjusts the volume level for a mic input channel.
Coarse gain can be adjusted in roughly 7dB increments.
Note: In general, you should set the Coarse Gain slider to 56dB
for a mic input, 28dB for active equipment that requires an input
between mic and line level, or 0dB for a line level input device.
Fine Gain Fine Gain adjusts the input volume level for a mic input but in increments
of 0.5dB.
Acoustic Echo Cancellation
(AEC)
AEC (Acoustic Echo Cancellation) reduces or removes acoustical echo
from an input signal, thereby improving audio clarity. CONVERGE Pro
2 devices perform AEC using the full bandwidth (20Hz to 22kHz) of
the signal. AEC uses a reference source to perform AEC based on the
acoustic characteristics and dynamics of a specific room.
Noise Cancellation (NC) Noise Cancellation is a process in which ambient (background) noise is
removed from an input signal, with no noticeable degradation in signal
quality. This settings is used primarily for audio and video conferencing.
Mute Mute a microphone.
Filter Filters enable you to shape the audio signals from mic inputs channels
for improved audio quality. Up to four filters can be added to a mic input
channel. Available filter types are All Pass, High Pass, Low Pass, Notch,
and Parametric Equalizer (PEQ).
Automatic Level Control (ALC) ALC automatically keeps an input signal at a constant level, and is
generally used to keep speech levels constant onMic Input channels.
Automatic Gain Control (AGC) AGC keeps an input signal at a target gain level that you select, and is
generally used for Line Input channels.
Delay Delay lets you add a specified amount of delay into specified channels.
Introducing an appropriate amount of delay to the forward-mounted
driver(s) re-establishes the acoustical alignment necessary for proper
sound imaging in a room. The same principle of introducing delay applies
to separate speaker enclosures located various distances from the
listening area.
