THANK YOU FOR
CHOOSING POLSEN.
The Polsen MP60 Microphone Preamp is a compact, single-channel
mic pre that can add up to 60 dB of clean gain to dynamic and
condenser microphones.
This preamp features balanced XLR and unbalanced 3.5 mm
inputs and outputs, so it can boost mic signals for a wide variety of
applications whether it’s in studio recording, broadcast, or podcast.
Pro features like a 120 Hz high-pass lter and a phase switch ensure
your sound will be full and robust without added noise or coloration.

OVERVIEW

1. 8-level signal level and clip indicator
Indicates the level of the outgoing signal. The red
clip indicator lights up when the signal is too loud
and distorting. If the clip indicator continually lights
up, turn down the gain until the loudest portion of
the signal does not light up the clip indicator.
2. Power LED indicator
3. Power button
4. Microphone gain control
Adjusts the microphone’s signal strength.
5. Phantom power switch
Press to activate phantom power when connecting
a condenser microphone that requires phantom
power to operate.
6. Low cut filter switch
Press to activate the low cut filter. The filter
decreases frequencies below 120 dB by 3 dB.
This will minimize low-end room and ambient
noise as well as noise from air conditioning ducts,
fans, and overhead lights.
7. Phase switch
Press to activate the Phase switch. Out-of-phase
audio sounds thin due to missing frequencies.
Activating the phase switch reverses the
microphone signal’s polarity to maintain a full
sound. Use the phase switch in two-mic setups,
e.g., microphones placed above and below a drum,
or close and room mics for recording dialog.
8. Unbalanced 3.5 mm mic input
For use with devices that have a 1/8"(3.5 mm)
connector.
9. Power input
Attach the included power cord.
10. Unbalanced 3.5 mm mic output
For devices with 1/8"(3.5 mm) connector. Output
can also be used for headphone monitoring.
11. Balanced XLR output
Connect to a mixing board, PA system, or audio
interface with balanced XLR inputs.
12. Balanced XLR mic input
Connect an XLR microphone.
