6.1 PFL : Pre-Fader listening

When any PFL button is depressed the main meters will change to displaying PFL level. PFL is the way to hear, cue and set up a piece of music before you play it out in the mix.

ϑIn the club environment, things get messy. You can’t hear any sound in isolation, either on a foldback system or headphones, because both are to some extent drowned out by the main PA system. You should, however, be able to hear the PFL signal loud enough to detect the beat, cue starts etc. What you can’t do is to judge by ear exactly what level the next track will come in at. For that you must use your eyes, and the highly-accurate bargraph VU meters.

PFL is also used to accurately check input GAIN. With a channel’s PFL button engaged (DOWN) you can accurately measure the input GAIN by making a typical noise or playing a typical piece of music and observing the main VU meters.

ϑIf you are in the habit of slamming the channel faders all the way up (+6 dB), try to keep your MAIN OUT control at a compensatory -6 dB to make sure you don’t risk distortion. To do this first set up output section EQ to suit the room or yourself. Now successively engage and disen- gage PFL on the channel currently playing, all other channels silent. Adjust MAIN OUT until the PFL and MAIN meter readings are identical. With channel faders at +6 dB and main output level at -6 dB your DX100 has unity gain from input to output. Now PFL and MAIN metering should show the same level, allowing direct visual comparison between outgoing (playing) and incoming (cue) tracks.

+If you re-adjust output EQ the above will no longer be true : re-set MAIN OUT level as described in the paragraph above !

6.2 Headphones - read carefully!

The PHONES section lies to the far left hand side of the DX100, below the DJ MIC level control. (The PHONES

TRS socket is on the front panel right.) PHONES controls headphones output level. Right, that’s the

easy bit explained. Now pay attention. BALANCE controls the blend of the PFL and MAIN mix signals. This gives you the interesting possibility of hearing both the outgoing (MAIN) and incoming (PFL) tracks simultaneously through a single output, via your headphones.
