The new CFX Series are the first "effects" mixers that meet Greg Mackie's stringent standards for sound quality, low noise, and high headroom.
Mackie's Digital Engineering staff contributed sophisticated EMAC 32-bit digital effects that are the equal of outboard processors. They spent a ridiculous amount of time perfecting a graphic EQ section. And they packed the CFX Series mic/line mixers with extra features.
CFX20 Features
High-headroom mic preamps with RF rejection
20 channels (16 mic/line mono, and 2 stereo line channels)
32-bit EMAC(TM) digital effects with 9 reverbs, 4 delays, phaser, chorus, flange; 2 parameter controls + EFX wide spatial expander
External and internal EFX sends
EFX to Monitor control
9-band stereo graphic equalizer
Inserts on all mic channels and main mix
True 4-bus design with direct sub outs and L/R assign
2 Pre/Post Aux sends and internal/external FX level sends on each channel
3-band EQ with swept mid (100Hz to 8kHZ) on mic/line channels
4-band EQ on stereo line channels
Pan, Mute, PFL solo on each channel
Inserts and 100Hz low-cut filters on all mic/line channels
Subwoofer output from built-in 18dB/oct. 75Hz crossover
Ingenious BREAK switch
Headphone output with level control
Tape/CD inputs with level control assignable to Main Mix via Break switch
Logarithmic taper 60mm faders
48V phantom power
12V BNC lamp jack
CFX Series Features
16 digital effects with 32-bit internal EMAC processing - 2 adjustable parameters.
Studio-quality, 9-band stereo graphic program equalizer. Bottom line: CFX(TM) mixers' graphic EQs are exceptionally low-noise, low-distortion, and don't suffer from any nasty phase-shift problems.
Level-setting LED for each channel.
Trim Control with 50dB of mic gain (for timid vocalists or low-output mics. +30dB of line level gain and a full 15dB of attenuation to "pad" hot signals.
Inserts on all mic channels and mains.
Aux Sends, switchable to pre-fader for monitor use.
External and internal EFX Sends.
12kHz shelving High frequency EQ.
Sweepable peaking Midrange EQ (only on mono input channels). Ultra-wide 100Hz to 8kHz bandwidth lets you use this control as an extra LF or HF EQ, too.
80Hz shelving Low frequency EQ.
Pre-Fader Solo switch lets you monitor the channel via headphones. It's also the key to fast, accurate level setting. Just press Solo and adjust the channel's trim control until the Zero Level LED flickers. You've now maximized headroom and minimized noise for the channel in a matter of seconds.
Subgroup buses "collect" channel signals assigned to them so you can submix vocals, drums, nose flute quartets, etc.
Mondo-nifty Break Switch mutes all channels (and routes Tape input to the mains) while you're on break so you don't have to worry about feedback or some idiot grabbing a mic for an impromptu poetry reading.
The Rude Solo Light that made us what we are today. (Whatever that is.)
Tape Level Control.
12V BNC lamp socket.
RCA-type unbalanced tape/CD inputs and tape outputs.
Balanced/unbalanced 1/4 in. TRS and balanced XLR outputs for mains.
Headphone jack with level control.
Subwoofer output from built-in 18dB/oct. 75Hz crossover!
Extra Utility Outputs with their own level control (post-Main Fader).
Long-wearing 60mm logarithmic taper faders give you smooth, linear control throughout the fader's entire travel.
Solid steel chassis is punched bent and painted by gigantic automated machines supervised by medium-sized, non-automated Mackoids.
On the back: built-in power supply (instead of an outlet-eating wall wart) uses easily-replaceable standard IEC line cord.
