9 CONVER TING TO RACKMOUNT MODE Not only is the new CR1604-VLZ a compact, professional-quality tabletop mixer , it’s rack- mountable! Its unique rotating input pod makes this possible. One of the things that revolutionized the com- pact mixer industry was the “convertible pod” found on the original, classic CR-1604. Using an ordinary Phillips[...]

10 At the risk of stating the obvious, this is where you plug everything in: microphones, line-level instruments and effects, and the ulti- mate destination for your sound: a tape recorder , P A system, etc. A few of the features described in this section are on top of the mixer , but most are out back on the “pod.” E-Z INTERF ACE Concerned abo[...]

11 LINE INPUTS These 1 / 4 " jacks share circuitry (but not phantom power) with the mic pr eamps. Y ou can use these inputs for virtually any signal you’ll come across, from instrument levels as low as –40dB to operating levels of –10dBV to +4dBu, as there is 40dB of gain available via the TRIM knob . Always be sur e to perform the Level[...]

12 SPLIT MONITORING With split monitoring, you use the first eight channels for your sound sources: vocal mics, drum mics, keyboard/synth outputs, guitar effects outputs, that sort of thing. From there, the channels manipulate the sound, but ar e not assigned to the output section. Instead, they’re patched from the channel’ s DIRECT OUT jacks t[...]

13 EFFECTS: SERIAL OR P ARALLEL? Y ou’ve heard us carelessly toss around the terms “serial” and “parallel.” Here’ s what we mean by them: “Serial” means that the entir e signal leaves the mixer ( INSERT send), is routed through the effects device, and returns to the mixer ( INSER T return). Examples: compr essor , lim- iter , graphi[...]

14 This method is exactly the same as the double- busing featur e found in other mixers. Built-in double busing is nothing mor e than Y -cords living inside the mixer instead of hanging out the back. If we had room for the extra jacks, we would have thrown them in, but we don’t, so we didn’t. Sonically , there is no difference whatsoever . Y -c[...]

15 MAIN INSER T These 1 / 4 " jacks are for connecting serial effects such as compressors, equalizers, de- essers, or filters . The INSERT point is after the mix amps, but befor e the MAIN L-R MIX fader . Insert cables must be wir ed thusly: “tip” This plug connects to one of the mixer’s Channel Insert jacks. “ring” tip ring sleeve S[...]

16 POWER SWITCH If this one isn’t self-explanatory , we give up. Y ou can leave this switch on all the time; the CR1604-VLZ is conservatively designed, so heat buildup isn’t a problem even in 24-hour -a-day operation. There’ s nothing that will burn out or get used up. Y ou may notice that the CR1604- VLZ’s “pod” feels quite warm (the p[...]

17 CHANNEL STRIP DESCRIPTION A Clean Fade Faders are not rocket science — they operate by dragging a metal pin (the wiper) across a carbon-based strip (the track). It is possible for airborne crud to land on the track. Should that happen, you may hear scratchy noises or signal drop- outs as the wiper stumbles over the crud. Do all you can to keep[...]

18 If you’re printing new tracks or bouncing ex- isting ones, you’ll also use the 1–2 and 3–4 switches, but not the L–R switch. Here, you don’t want the subgroups sent back into the MAIN L-R MIX , but sent out, via the SUB OUTS jacks, to your multitrack inputs . However , if you’re printing tracks via the DIRECT OUT jacks , all the ch[...]

19 CONST ANT LOUDNESS ! ! ! The CR1604-VLZ’s PA N controls employ a design called “Constant Loudness.” It has nothing to do with living next to a freeway . As you turn the PA N knob from left to right (thereby causing the sound to move from the left to the center to the right), the sound will appear to r emain at the same volume (or loudness)[...]

20 20 Hz 100 Hz 1k Hz 10k Hz 20k Hz –15 –10 –5 0 +5 +10 +15 20 Hz 100 Hz 1k Hz 10k Hz 20k Hz –15 –10 –5 0 +5 +10 +15 Most of the root and lower harmonics that define a sound are located in the 100Hz–8kHz frequency range, and you can cr eate drastic changes with these two knobs. Many engineers use MID EQ to cut midrange frequencies, no[...]

21 W e recommend going into a ster eo reverb in mono and r eturning in ster eo. W e have found that on most “ster eo” r everbs, the second input just ties up an extra aux send and adds nothing to the sound. There ar e exceptions, so feel free to try it both ways. Should you choose to use two aux sends, use the “odd” AUX ( 1 , 3 or 5 ) to fe[...]

23 Now you know how to select the signals you want to send to the engineer’s control room and/or phones. From there, these signals all pass through the same level control, aptly named: C-R/PHONES As you might expect, this knob controls the levels of both the ster eo C-R OUTS and PHONES output . The control range is from off through unity gain at [...]

24 MODE (NORMAL (AFL)/LEVEL SET (PFL)) Y ou may have already seen this, but in case you missed it: The CR1604-VLZ’s solo system comes in two flavors: NORMAL (AFL) (sometimes called SIP , or solo-in-place) and LEVEL SET (PFL) (sometimes called PFL, or pre-fader -listen). In NORMAL (AFL) , the soloed channel’s signal is sent dir ectly to the C-R [...]

25 METERS The CR1604-VLZ’ s peak metering system is made up of two columns of twelve LEDs. Decep- tively simple, considering the multitude of signals that can be monitor ed by it. If nothing is selected in the SOURCE matrix and no channels are in SOLO , t h e meter display will just sit there. T o put them to work, you must make a selection in th[...]

26 AUX SENDS SOLO Once again, in a live sound situations AUX SEND 1 and 2 are likely to feed your stage monitors. Y ou’ll want to check the mix you’re sending them, and that’s what these two but- tons are for . ( AUX 3 through AUX 6 have no such switch.) Below each switch is a green LED that, just like the channel’s –20 LED , helps you fi[...]

27 MIX ( MAIN MIX TO SUBS switch up) and you did a drum fade-out using subgroup faders 1 and 2 , the “dry” signals would fade out, but the “wet” signals would keep on singing. All you would hear is the drum reverb (the “wet”), and none of the original drum signals (the “dry”). That’s because the r everb is being fed by the channel[...]

28 MODIFICA TIONS CR1604-VLZ Post-EQ Mod This changes AUX SENDS 1 and 2 , with the pre switch engaged, to r eceive their signals post- EQ instead of pre- EQ . The signal remains post-low cut, pre-mute and pr e-fader . W ith the pre switch disen- gaged (up), the signals ar e not affected by the mod. The following must be performed for each channel y[...]

34 This Glossary contains brief definitions of many of the audio and electronic terms used in discussions of sound mixing and recording. Many of the terms have other meanings or nuances or very rigorous technical definitions which we have sidestepped here because we figur e you already have a lot on your mind. If you’d like to get more informatio[...]

35 console A term for a sound mixer , usually a large desk-like mixer . cueing In broadcast, stage and post-production work, to “cue up” a sound source (a r ecord, a sound effect on a CD, a song on a tape) means to get it ready for playback by making sur e you ar e in the right position on the “cue,” making sure the level and EQ ar e all se[...]

36 echo The reflection of sound from a surface such as a wall or a floor . Reverberation and echo ar e terms that can be used interchangeably , but in audio parlance a distinction is usually made: echo is considered to be a distinct, r ecogniz- able repetition (or series of r epetitions) of a word, note, phrase or sound, whereas r ever- beration is[...]

37 second, which gives us the sensation of pitch, harmonics, tone and overtones. Fr equency is measured in units called Hertz (Hz). One Hertz is one repetition or cycle per second. gain The measure of how much a circuit ampli- fies a signal. Gain may be stated as a ratio of input to output values, such as a voltage gain of 4, or a power gain of 1.5[...]

38 input module A holdover from the days when the only way that real consoles wer e built was in modular fashion, one channel per module. See channel strip . knee A knee is a sharp bend in an EQ response curve not unlike the sharp bend in your leg. Also used in describing dynamics processors. level Another word for signal voltage, power , strength [...]

39 pan, pan pot Short for panoramic potentiometer . A pan pot is used to position (or even move back and forth) a monaural sound source in a ster eo mixing field by adjusting the source’ s volume between the left and right channels. Our brains sense stereo position by hearing this dif- ference in loudness when the sound strikes each ear , taking [...]

40 equals the center frequency divided by the dif- ference between the upper and lower –3dB frequencies. A peaking EQ center ed at 10kHz whose –3dB points are 7.5kHz and 12.5kHz has a Q of 2. RCA phono jack— or RCA jack or phono jack An RCA phono jack is an inexpensive con- nector (female) introduced by RCA and originally used to connect phon[...]

41 stereo Believe it or not, ster eo comes from a Greek word that means solid. W e use stereo or stereophony to describe the illusion of a con- tinuous, spacious soundfield that is seemingly spread around the listener by two or mor e re- lated audio signals. In practice, ster eo often is taken to simply mean two channels. sweep EQ An equalizer that[...]

42 APPENDIX B: CONNECTIONS “XLR” CONNECTORS Mackie mixers use 3-pin female “XLR” connectors on all microphone inputs, with pin 1 wired to the grounded (earthed) shield, pin 2 wired to the “high” (”hot” or positive po- larity) side of the audio signal and pin 3 wired to the “low” (“cold” or negative polar - ity) side of the s[...]

43 goes to the ground (earth) connection at the unbalanced input. In most cases, the balanced ground (earth) will also be connected to the ground (earth) at the unbalanced input. If there ar e ground-loop problems, this connection may be left disconnected at the balanced end. • When connecting an unbalanced output to a balanced input, be sure tha[...]

44 input, for example, will automatically unbalance the input and make all the right connections. Conversely , a 1 ⁄ 4 " TRS plug inserted into a 1 ⁄ 4 " unbalanced input will automatically tie the ring (low or cold) to ground (earth). TRS Send/Receive Insert Jacks Mackie’s single-jack inserts ar e the three- conductor , TRS-type 1 [...]

45 MUL TS AND “Y”s A mult or “Y” connector allows you to route one output to two or more inputs by simply providing parallel wiring connections. Y ou can make “Y”s and mults for the outputs of both unbalanced and balanced circuits. Remember: Only mult or “Y” an output into sev- eral inputs. If you need to combine several out- puts i[...]

46 APPENDIX C: BALANCED LINES, PHANTOM POWERING, GROUNDING AND OTHER ARCANE MYSTERIES What is it, exactly? The obvious external power source for any modern microphone is a battery . About the only electronic advantage that a battery has is that its output is pure DC. The only other advantage is to the battery company — you have to keep on buying [...]

47 the DC power is applied common-mode. The audio travels via pins 2 and 3, the power trav- els between pins 2 and 3 simultaneously , and pin 1 is the ground for both audio and power . Microphones that do not r equir e power simply ignore the DC pr esent between pin 2/pin 3 and pin 1. If you measure with a voltmeter between pin 2 and pin 3, you wil[...]

48 Do’ s and Don’ts of Fixed Installations If you install sound systems into fixed installa- tions, ther e are a number of things that you can do to make your life easier and that incr ease the likelihood of the sound system operating in a predictable manner . Even if you don’t do fixed installations, these are good practices for any sound sy[...]

49 Many “authorities” tell you that shields should only be connected at one end. Some- times this can be true, but for most (99%) audio systems, it is unnecessary . If you do every- thing else correctly , you should be able to connect every component of your audio system using standard, off-the-shelf connecting cables that are available at any [...]
