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.
