Preamplifiers are compact mic preamps for applications where a
microphone must be connected to a line level audio input on a device
such as a switcher or line level mixer. Mic level signals are boosted up
n Precise mic input gain adjustment – A continuous, rotary trim
to balanced or unbalanced line level signals. These preamps also allow
a microphone to be connected to the Aux/Mix input on the Extron
MediaLink™ series of switchers.
MLP 101
The front panel of the MLP 101 features a continuous gain control
for precise adjustment of input microphone level. Toggle switches are
n Remote volume and mute control capability – Allows volume
provided to engage 48 volt phantom power for compatibility with
condenser microphones, and a switchable low cut filter at 75 Hz to
reduce rumble and wind noise picked up by the microphone. Input
n Selectable 75 Hz low cut filter – Rolls off frequencies below
and output connections are provided on the rear panel using captive
screw connectors. The MLP 101’s output can be remotely controlled
for microphone level adjustment via a 10k potentiometer, and muting
