CFX Series CFX Series Dimensions CFX SERIES 12-, 16-, and 20-Channel Mic/Line Mixers 21.4"/ 544mm 17.2"/437mm 5.0"/ 127mm 25.6"/650mm 15.7"/399mm (continued from page 1) 4.6"/117mm 2.1"/53mm Utility outputs that are independent of the master gain control, and tape and sub bus outputs.  The EMAC Digital Effects section includes four con- trols at the top. EFX 2 regulates the signal level being sent to the EMAC effects processor from an individual channels strip's EFX 2 aux send. The overall level is monitored by the CLIP LED to prevent overload. TO MAIN MIX controls the amount of effects sent to your main mix. The two EFFECTS TO MONITOR knobs let you 16.2"/412mm add effects to stage monitor mixes independently of the EFX levels added to the main mix. Below the level controls is the preset selector for picking which effect you want. The characteristics of these presets can be changed with the TIME/RATE and DAMPING/DEPTH knobs. Between these controls are a BYPASS SWITCH and an EFX WIDE control. Wide adds psychoacoustic "width" or "depth" to all effects except delay and phaser.  The Stereo Graphic Equalizer is nine bands with +15 dB of gain and centers at 63 Hz, 125 Hz, 250 Hz, 500 Hz, 1 kHz, 2 kHz, 4 kHz, 8 kHz, and 16 kHz. This EQ is exceptionally low-noise, low-distortion, and free of phase distortion.  Trim Controls have 50 dB of mic gain, +30 dB of line-level gain, and a full 15 dB of attenuation to "pad" hot signals. Each channel also includes a Zero Level Set LED for easy level setting. All mic channels have a 100 Hz low cut filter to reduce stage vibration, mic stand rumble, and wind noise. Each channel includes a Pre-Fader Solo switch.  Channel EQs are as follows: 12 kHz shelving HIGH frequency EQ, sweepable peaking Midrange EQ (only on mono input channels), with a 100 Hz to 8 kHz bandwidth. Stereo channels employ a 2-stage fixed-frequency MID EQ, HI-MID is centered at 3 kHz; LOW-MID is centered at 400 Hz; and a LOW EQ that is shelved at 80 Hz.  Log-taper 60 mm faders deliver a consistent fade throughout the fader's throw. These faders have a co-polymer membrane that provides a continuously sealed barrier against dust and liquids without interfering with fader travel. Similarly, the fader's longwearing contact material (first designed for use in exterior automotive sensors) means longer fader life and improved resistance to the elements.  The CFX Series mixers are designed for continuous, hassle-free use in any sound reinforcement installation. And they're packed with useful features and practical routing capabilities. Simply stated, these mixers offer more features, more peace of mind, and more possibilities than any other mixers in their class.  And they're Mackies. 3 OF 8 PAGES
