9.LIMIT LED: This LED illuminates when the limiter circuit is activated, indicating that the amplifier is nearing full output and the limiter is keeping peak signals from clipping the output.

10.LIMITER SWITCH: Press this switch in to add the limiter circuit. If the signals driving the amplifier start to peak, the limiter will automatically reduce the signals to prevent clipping, and the

LED [9] will flash. The limiter will help keep the amplifier’s output “clean” up to high output levels and avoid potentially damaging distortion.

11.FAULT LED: This LED illuminates amber if the amp thermals and shuts down or develops other fault conditions. See “Fault/Thermal Considerations” on page 18 for more information.

12.AUDIO IN: The audio output from line- level sources, such as an iPod®, MP3, or CD player, can connect to this

1/8" TRS stereo input. The incoming audio is mixed with the preamp signals, so you can play along to a practice track as you listen with headphones. (The audio coming in here only plays in the headphones, and appears nowhere else. It is not affected by the volume control.)

13.PHONES: Use this 1/8" TRS stereo output to connect your headphones. The output here is a mix of the line-level signals reaching the amplifier, and any incoming audio from the audio in

jack [12].

If you just want to listen and practice through headphones, disconnect the speaker-level outputs [18] from the speaker cabinet. There is no harm in playing the PF-350 without speakers.

Before putting on headphones, make sure the volume control [8] is turned down, and (if connected) any external audio source has its level turned down. This will reduce the chance of hearing damage due to loud volumes.
