USER MANUAL PMA-1 Polsen

The PMA-1 personal headphone amplifier is perfect for monitoring your performance on stage or in the studio. The PMA-1 mixes a stereo or mono line-level signal from the aux out of a mixing board, sound card, or playback device. It allows you to blend or boost the volume of your performance independently from the rest of the track, and it lets you hear your performance with zero latency. The Mic gain adjusts the headphone volume of your microphone or instrument, while the input monitor controls the volume of the entire track. The result is the perfect personal headphone mix for an optimal performance.

POWERING THE PMA-1

Plug the 12 V power cord into the power input, and plug the power adapter into an outlet. The LED will light up.

CONNECTING THE PMA-1

Mic Input

Connect the microphone to the Mic Input with a balanced XLR cable.

Mic Thru

Run a balanced XLR cable from the Mic Thru port to the mic input of a mixing console or sound board.

Note: For condenser microphones, the PMA-1 does not supply its own phantom power, but it will pass along phantom power from a mixing board.

Monitor Input

Use a balanced or unbalanced 1/4 in. cable to connect the Monitor Input with the aux out of a mixing board, computer sound card, or line output of a playback device.

Headphones

Connect headphones to the 1/4 or 1/8 in. headphone jack.

Note: Do not use both headphones jacks simultaneously.

OPERATING THE PMA-1

Mic Gain

The Mic Gain knob controls the microphone volume in your headphones. This will increase or decrease the headphone volume of the microphone without affecting the signal level that's sent to the mixing board.

Monitor Level

The volume of the Monitor Level knob controls the overall mix. If the microphone level is too low in the headphones, turn up the Mic Gain before increasing the Monitor Level.

Stereo/Mono Switch

Select stereo or mono, depending on the signal that's sent to the Monitor Input.

• If a TS (mono) connector is connected to the Monitor Input, select mono.
• If a TRS (stereo) connector is connected to the Monitor Input, select stereo.

Ground/Lift Switch

When the PMA-1 is connected to a mixing board, the Ground/Lift switch should be in the up (LIFT) position. This will prevent the introduction of interference into the signal chain.

If there is an audible hum or noise in the headphones, pressing the switch to the down (GND) position will eliminate it.
