Frequently Asked Questions - PM-444Pi Omnitronic
How do I connect turntables to the PM-444Pi?
Use the phono inputs (channels 1 and 2). Ensure your turntable has a ground wire connected to the ground terminal on the mixer.
Can I use the mixer without a power adapter?
No, the PM-444Pi requires an external power adapter (AC 100-240V). It does not have an internal power supply.
What is the difference between the Master and Booth outputs?
The Master output (XLR) is for the main sound system. The Booth output (TRS) is a separate monitor feed, typically used for the DJ's headphones or booth speakers.
How do I clean the crossfader?
Remove the crossfader and spray contact cleaner inside the fader channel. Move the fader back and forth to distribute the cleaner. Allow it to dry before reinstalling.
Why is there no sound from one channel?
Check that the channel fader is up, the EQ knobs are centered, and the cue/assign switch is not set to 'Off'. Also verify input cables and that the source device is working.
Can I use the microphone input as a line input?
Yes, the microphone input accepts both XLR and TRS connections. It can be used for line-level sources, but the gain may need adjustment.
What type of headphones should I use?
Use closed-back headphones with a 1/4' TRS connector. The headphone output is standard impedance (32-300 ohms).
How do I replace the crossfader?
Remove the top plate, unscrew the old fader, disconnect its ribbon cable, and install a new Omnitronic replacement fader. Note the orientation of the connector.
Does the mixer have built-in effects?
No, the PM-444Pi is a pure analog mixer without digital effects. External effects can be added via the send/return loop (if available) or inline.
What is the weight of the PM-444Pi?
The mixer weighs approximately 2.5 kg (5.5 lbs), making it portable for mobile DJs.
