  • Controls for Monitor & Microphone Levels
  • 1/4" & 3.5mm Stereo Headphone Outputs
The Polsen PMA-1 is a personal monitoring amplifier offering coloration-free signal amplification for vocalists and musicians in studio, live stage, and mobile-recording applications. It allows an artist to adjust the blend of their own microphone and monitor levels via easy-to-use gain/volume controls. Setup is straightforward; hook up a mono or stereo line-level source to the 1/4" TRS monitor input, and plug in your preferred headphones to the 1/4" or 3.5mm stereo headphone jack. A mono/stereo switch is provided to enable proper routing of a single- or dual-channel input to both sides of your headphones.

Connect a microphone such as a dynamic, ribbon, or condenser mic into the balanced XLR input, then connect the balanced XLR thru jack to a mixing console or mic preamp; any phantom power sent from your mic preamp will pass unimpeded to your microphone. This allows convenient "more me" functionality without inhibiting the creative workflow. All-analog circuitry ensures zero-latency monitoring and microphone throughput. In the event of hum from a ground loop, flip the ground-lift switch for noise-free monitoring. The PMA-1 features a compact, sturdy enclosure for reliable use on and off the road, and includes a 12 VDC power supply.

I bought this a year or so ago and have been using it to use to boost the monitor level for my somewhat high-impedence headphones. I just tried the mic port for the first time. I am finding that the mic input leaks into the monitor channel even with the mic volume at zero. Raising the mic volume does raise the mic input, but also adds quite a bit of noise. And when the monitor volume is at zero, the mic channel does not sound even with the level set up high. I expected the two inputs to be independently controllable. Is there a way to accomplish this?
Asked by: Peter
Hello. Thank you for your description of usage. This device is designed to where the Monitor level control is a master control over the overall mix output of the mic input and monitor input. The two input channels can not be separated. If needed to balance the levels of the mic and playback in your headphones, you'd have to balance the mic gain on the Polsen, and the headphone out of the Steinberg individually. As for the metronome bleed through the mix when the gain is down, the headphone out level of the metronome is a much hotter signal than the expected mic level intended for the mic input. Due to this, it is possible that the level would pass through while the gain is turned down. I would recommend revisiting the metronome built into your recording software. This can be used while recording and not actually be on your recorded tracks. By going this route, all you would need the Polsen for is to boost the level of the headphones.

Asked by: Jon
This can be used with earbuds. The type of mic would depend on what you are doing with it. For a live vocal performance situation, here's a general mic recommendation: B&H # SEE945.

Will this item add a stronger bass and more lows to the sound of my headphones or it just raises the volume?
Asked by: Yehudah
This only controls volume, not tone.
