[. . . ] There is no boost or cut at the center detent position. Frequencies of 80 Hz and below represents the punch in bass drums, bass guitar, fat synth patches, and high-testosterone male singers. While adding boost, also engaging the LOW CUT (18) switch can create an audible low frequency boost without boosting stage rumble, mic-handling clunks, and breath pops. +15 +10 +5 0 LOW ­5 ­10 ­15 20Hz 100Hz 1kHz 10kHz 20kHz Mono Channel 12 AUXILIARIES AUX 1/MON allows you to create a separate mono mix which can be used to feed stage monitors. AUX 2/EFX allows you to create another mono mix to feed the EMAC internal effects, and any external effects processor you have. The channel AUX knobs adjust how much of each channel is added to each aux mix. The adjustment ranges from off, through unity, and on up to 6 dB of extra gain. The stereo channel AUX knobs control a mono sum of the channel's stereo signals. For example, on the DFX·12, channel 9 (L) and 10 (R) mix together to feed that the channel 9/10 AUX knobs. The master AUX SEND (38, 41) knobs adjust the overall aux output levels. These are more than mere effects and monitor sends: they can be used to generate separate mixes for recording or "mix-minuses" for broadcast. the center position, the left and right channel signals pass through to the main mix unaffected. If PAN is turned left, the right channel is attenuated; if turned right, the left side is attenuated. LEVEL SET 11/12 U 24. MUTE When you engage a channel's MUTE switch, its signal disappears from the main mix, tape, AUX 1, AUX 2 and headphones. The only exception is the INSERT (4) outputs. -20dB +20dB GAIN U EQ HI 12k 25. FADER This fader is the master level control for the channel's signal. Subtle adjustment of the channels' fader positions is the key to a finelytuned mix. Typically (providing the GAIN (16) control is set correctly) the fader position will be positioned somewhere between 0 dB ("U") and ­30 dB. If you have a fader set all the way up, that's usually a sign that your GAIN is set too low. Conversely, if the fader is set way down, your GAIN may be set too high. -15 +15 U LOW 80Hz -15 +15 AUX U O O 1 MON +6 U O O 2 EFX 21. AUX 1/MON AUX 1 is designed for feeding a separate monitor mix to the musicians on stage, via the AUX 1 SEND (7) output jack. The signal is tapped off before the channel EQ section, and before the channel fader. Only the channel GAIN, MUTE and LOW CUT will affect the output to your monitors. +6 "U" = UNITY GAIN Mackie mixers have a "U" mark on almost every level control. This stands for "unity gain, " meaning there is no change in signal level. [. . . ] · If the POWER LED is blinking, switch the mixer off for a few seconds, and disconnect all connections except the linecord. Switch it back on, and if the LED continues to blink, the mixer may need repair. 20 APPENDIX B: Technical Info Specifications DFX·6, DFX·12 Mixer Section Frequency Response Mic Input to any Main output (GAIN at 0 dB): +0, ­1 dB, 16 Hz to 30 kHz Maximum Voltage Gain Mic Input to Insert Output: Tape Output: Main Output: Aux Send: Line Input to Insert Output: Tape Output: Main Output: Aux Send: Stereo Line Input to Tape Output: Main Output: Aux Send: Tape Input to Main Output: Effects Return to Main Output: 50 dB 60 dB 76 dB 85 dB 30 dB 40 dB 56 dB 66 dB 20 dB 40 dB 50 dB 22 dB 22 dB Distortion THD and SMPTE IMD; 20Hz to 20kHz Mic Input to Main Output: < 0. 05% @ +4 dBu output Noise 20Hz to 20kHz BW (150 source impedance) Equivalent Input Noise (EIN): ­127 dBu Residual Output Noise: Main, Monitor, & Effects outputs Channel & Master levels off ­95 dBu Input Impedance Mic Input: 3 k, balanced Line Input: 40 k, balanced Insert Input, Stereo Line Input, Tape Input, and Effects Returns: 10 k, unbalanced Common Mode Rejection Ratio (CMRR) 60 dB @ 1kHz, Gain @ unity Crosstalk Adjacent Inputs or Input to Output: ­90 dB @ 1kHz Fader Off ­90 dB @ 1kHz Mute Switch and Break Switch Mute ­80 dB @ 1kHz Output Impedance Main Output, Insert Output, Tape Output, and Effects Sends: 150 Digital Effects Resolution: Number of Presets: 16-bit, 2-channel 16 Input Level Trim Control Range 0 to +50 dB Channel Level Set LED (Sensitivity) 0 dBu (normal operating level) Phantom Power +48V DC on mono channels VU Meters Main L/R 12 segments: Clip (+16), +12, +8, +4, 0, ­4, ­8, ­12, ­16, ­20, ­24, and ­30 Equalization Low Cut: 75 Hz, ­18 dB/octave Channel EQ: High ±15 dB @ 12kHz Low ±15 dB @ 80Hz Stereo Graphic EQ (5 bands): Q = 1. 414, ISO octave centers ±12 dB @ 60, 250, 1k, 3. 5 k, 12 kHz AC Power Requirements 100 ­ 240 VAC, 50/60 Hz, 30 watts (Capable of operation from 85% to 110% of rated line voltage. ) Mixer Rated Output Main, Aux, & EFX: +4 dBu Maximum Rated Output: +20 dBu Disclaimer Since we are always striving to make our products better by incorporating new and improved materials, components, and manufacturing methods, we reserve the right to change these specifications at any time without notice.
