7 PRO MIXER DX1000 1 . THE MANUAL We know that reading manuals can be a bore, and that you are probably impatient to get started with your new DX1000 mixer, if you haven’t already! It is true that with a modicum of knowledge about audio equipment you could get up and running successfully, but chances are you will not be able to exploit the full p[...]

8 PRO MIXER DX1000 2.1 Highly accurate main and PFL peak—reading bargraph meters The main output level is constantly monitored by a pair of highly accurate main bargraph meters . In addition, all channels have PFL (Pre-Fader-Listen) . This means that you can see (on a separate PFL bargraph meter) and hear (on your headphones and/or monitors) the [...]

9 PRO MIXER DX1000 3 . MONO INPUT CHANNEL Plug a mic or line source (tape, CD player etc.) into the appropriate MIC or LINE input. Speak or play music at typical volume to check out and set up the channel. + The mic pre-amps are of the same quality as those in our award-winning EURODESK studio consoles. These give an incredibly warm, clear and nois[...]

10 PRO MIXER DX1000 3. 4 Equalizer The mic channel EQ section comprises three control knobs and one switch. Depressing the LOW CUT switch rolls off the bass end (-18 dB/oct @ 75 Hz). We recommend using this feature with microphones to eliminate “popping” and handling noise. Where loud music is playing, LOW CUT also helps to avoid bass feedback.[...]

12 PRO MIXER DX1000 4. 3 Equalizer The channel EQ section comprises three control knobs and two switches. The EQ ON switch activates the tone controls which enable cut and boost of TREBLE , MID and BASS frequencies respectively (see below for specs.) EQ can sweeten or effect a track, with the fading out and in of frequency bands being very popular.[...]

13 PRO MIXER DX1000 + Take care to ensure that SENSITIVITY is not set too high, otherwise spill from loudspeakers into the mic could trigger the talk over system, and the music volume will just keep going up and down! (You have set up an intermittent negative feedback loop.) Once SENSITIVITY has been set so that talk over is only being activated by[...]

14 PRO MIXER DX1000 + This is the first time we have come across any really BIG buttons on the DX1000. At this point it’s worth pointing out that all the smaller switches on your DX1000 are latching. This means they stay down until you hit them again. Big buttons are all non-latching, or momentary in operation. This means that they are only activ[...]

15 PRO MIXER DX1000 7 . HEADPHONES, MONITORS & PFL 7.1 Monitoring A separate stereo MONITOR output is provided. Level is controlled by a single 60 mm MONITOR stereo fader . The monitor signal is taken directly from the main mix. Engaging PFL anywhere on the board changes the monitor source to PFL. + Main fader adjustments will not affect the le[...]

16 PRO MIXER DX1000 + Another way to keep the monitors fixed on PFL is to make sure a PFL button is always left engaged somewhere on the desk. You could simply leave a PFL button depressed on an unused, unassigned channel. If your channel fader is always brought up to +6 dB (i.e. full-on as per usual with you DJ types) then comparing PFL values wil[...]
