[. . . ] Use only with a cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the apparatus. When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over. PORTABLE CART WARNING Carts and stands - The Component should be used only with a cart or stand that is recommended by the manufacturer. Quick stops, excessive force, and uneven surfaces may cause the Component and cart combination to overturn. [. . . ] €œU” LIKE UNITY GAIN Mackie mixers have a “U” symbol on almost every level control. This “U” stands for “unity gain, ” meaning no change in signal level. Once you have adjusted the input signal to line-level, you can set every control at “U” and your signals will travel through the mixer at optimal levels. What’s more, all the labels on our level controls are measured in decibels (dB), so you’ll know what you’re doing level-wise if you choose to change a control’s settings. 5k FREQ 8k U LOW 80Hz 150 100 When you engage a channel’s mute switch, its signal disappears from these outputs: MAIN , MAIN INSERT , SUB OUT 1-4 , OUT AUX SEND 1 & 2 , EFX SEND 1 & 2 (including the send to the EMAC EFFECTS ). The only thing it doesn’t PROCESSOR switch, so mute is the channel’s SOLO PFL you can audition channels, via headphones, without sending them to the main mix. SOLO PFL Engaging a channel’s SOLO switch causes this dramatic turn of events: The PHONES and Meters , which ordinarily receive the main mix signals, instead receive the SOLO PFL signal. PFL, being a mono signal, is sent to both sides of the PHONES outputs and to the LEFT meter. Additionally, the RUDE SOLO LED flashes obnoxiously to remind you that “you’re in solo. ” The SOLO PFL signal is tapped before the channel’s MUTE and Fader controls. It , LOW CUT does, however, follow GAIN , and EQ settings, making it the perfect tool for quick inspections of individual or mul, MUTE tiple channels. Although the “SET THE LEVELS” section of “QUICK START” (page 5) will get your levelsetting tasks accomplished, using the meters in PFL SOLO mode lets you really tune in. Instead of one flickering LED, you can make use of the 12-segment VU display in the meters. Signal before the fader If you have a channel’s fader set well below “U” (unity gain), SOLO won’t know that and will send a unity gain signal to the PHONES output. 48v POWER STATUS LEFT RIGHT CLIP 22 10 7 4 2 0 2 4 METERS The CFX mixer’s peak metering system is made up of two columns of twelve LEDs each, with thresholds ranging from –30 dB up to , “CLIP” (+22 dBu at the TRS MAIN OUT +28 dBu at the XLR MAIN OUT). The meters display the main mix, post MAIN MIX Fader , unless a SOLO PFL switch is engaged. When a SOLO PFL switch is engaged, the meters will instead display the solo infor). The meters, being a tool for the engineer, must display what the engineer is lisoutput. Tening to via the PHONES You can get a good mix with the meter’s peaks flashing anywhere between –20 and +10 dB. Most amplifiers clip at about +10 dB, and some recorders aren’t so forgiving either. For best real-world results, try to keep your peaks between “0” and “+7. € You may already be familiar with “+4” (+4 dBu=1.
