Adjust the Amplifier

1. If using the FrontRow CA1000 amplifier:
1. Follow the instructions in the CA1000 Installer Guide (under the Downloads
section at gofrontrow.com/ezroom) to connect the CA1000 to a computer running
the CA1000 configuration software. (Note that the configuration software version
must match the CA1000 build version. Follow the guidance under the ezRoom
Downloads section to verify.)
2. Using the configuration software, set Channel 4 to:
• Enabled
• Mic On
• An appropriate Gain level (we recommend setting 30, but be sure to test
before packing up your tools).
• An acceptable Threshold level (sets the level at which attenuation /ducking
of other audio will occur as the talker speaks into the mic; setting 50 recom-
mended).
• An acceptable Setback level for channels 1 to 3 (sets the amount of attenua-
tion of the channel while the mic signal is active; setting 8 recommended).
• Set Mic Restore time (the amount of time the amplifier waits between the end
of an active microphone signal and resetting the other channels to their nor-
mal volume levels).
2. If using the FrontRow CM3000 amplifier:
1. Using a computer on the same network as the CM3000, type the IP address of
the amplifier into a web browser.
2. Go to Audio.
3. Under Channel 4 :
• Check the Enable box.
• Set Gain level (we recommend setting 30, but be sure to test before packing
up your tools).
• Check the Mic box.
• Set Threshold level (sets the level at which attenuation /ducking of other
audio will occur as the talker speaks into the mic; setting 50 recommended).
• Set Setback levels for Channels 1 to 3 (sets the amount of attenuation of the
channel while the mic signal is active; setting 8 recommended).
• Set Mic Restore time (the amount of time the amplifier waits between the end
of an active microphone signal and resetting the other channels to their nor-
mal volume levels).
