[. . . ] DX1000 User's Manual Version 1. 1 February 2001 PRO MIXER www. behringer. com ENGLISH PRO MIXER DX1000 SAFETY INSTRUCTIONS CAUTION: To reduce the risk of electric shock, do not remove the cover (or back). No user serviceable parts inside; refer servicing to qualified personnel. WARNING: To reduce the risk of fire or electric shock, do not expose this appliance to rain or moisture. This symbol, wherever it appears, alerts you to the presence of uninsulated dangerous voltage inside the enclosure--voltage that may be sufficient to constitute a risk of shock. This symbol, wherever it appears, alerts you to important operating and maintenance instructions in the accompanying literature. [. . . ] PEAK lets you know if you're about to overload the channel (it lights at +18 dB). LED only responds to bass frequencies and is perfectly suited to keep an eye on the beats. As long as the signal LED is flashing on the beat (and the peak one isn't) you can be sure the gain is reasonable. Channel gain can be continuously adjusted by the GAIN knob (from -20 to +20 dB). + If you are in the habit of slamming the channel faders all the way up (+6 dB), try to keep your MAIN faders at a compensatory -6 dB to make sure you don't risk distortion. At this level PFL and MAIN meters should show the same level (check this by engaging PFL on the channel currently playing), allowing easy comparison between outgoing (playing) and incoming (cueing) tracks. Remember--distortion is not volume, and any distortion introduced before the power amplifiers and speakers will worsen your sound and cause amps and speakers to clip sooner. 4. 2. 2 Gain setting by using PFL Pre-Fader-Listen is the professional way to set gain, and we always recommend you do it if you have the time. Hit the PFL button to temporarily send the channel signal to the PFL meter . Adjust GAIN until the PFL meter is hitting the yellow (up to +10 dB) but not the red (clip). Once gain has been set for a channel, release its PFL button. + Normally you will want to PFL only one channel at a time. This might not be true if you are layering tracks, and/or using "Permanent PFL"--see the chapter 7 "HEADPHONES, MONITORS & PFL". Also note that the mono PFL meter is a sum of L and R channel signals. 4. STEREO INPUT CHANNEL 11 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. When you press the KILL switch the bass EQ is set to maximum attenuation independent of the setting of the bass EQ control. EQ Treble Mid Bass Shelving EQ Peaking EQ Shelving EQ Frequency 10 kHz 750 Hz 50 Hz Range +/- 12 dB +/- 9 dB +/- 12 dB Centre OFF OFF OFF Tab. 4. 2: Equalizer of the stereo channels + EQ is particularly useful if two or more music tracks are playing together, as frequencies often clash. Low frequencies in particular can phase and cancel, causing uneven bottom-end response. You can roll off the bass by turning BASS fully anti-clockwise. 4. 4 Output Channel level is controlled by a precision stereo 100-mm fader . + The faders used are high-quality true-log faders. These give ultra-smooth operation even at low levels, on a par with those used in the most expensive studio consoles. You wont hear anything in the main mix unless the channel is switched on by depressing the CROSSFADER switch . This sends the channel signal to either of two stereo submixes, which we call X and Y. The ASSIGN button selects between these two submixes, and a pair of LEDs clearly show you which of X or Y is currently selected per channel. The X and Y mixes are then routed to opposite ends of the main crossfader . + You can immediately tell if any channel is switched on (CROSSFADER switch depressed) by looking at the master ASSIGN X and ASSIGN Y indicators situated under the crossfader. 5. You would almost certainly want to attenuate the music while you speak.
