CFX.mkII Series Frequently Asked Questions
Q: How do I get signal out of the Main Outputs?
A: Unlike some other Mackie mixers, the CFX.mkII mixers do not automatically pass signal from the channels to the main outputs. There are also no L-R assign buttons on the channels to assign them directly to the main Left/Right bus. Therefore, you must send channels to the Subgroups and then route the Subgroups to the Main Outs. The most straightforward way to achieve this is to press the 1-2 assign buttons on all of the channels; these buttons are located next to each of the channel faders. This sends all of the channels to the first pair of Subgroups. Now bring up the first two Subgroup faders to the unity position. These are the blue faders below the effects section. Above Subgroup 1, press the Left button, and above Subgroup 2, press the Right button. This sends the Subgroups to the Main bus. By bringing up the main fader you will now hear sound from your Main Outputs. Leave the Subgroup section as it is and control the channel volume and pan from the channels themselves. If you want to do more elaborate subgroup routing, remember the following: pan the signal between Subgroups 1 and 2 and Subgroups 3 and 4 just as you would pan between the Left and the Right, and assign the Subgroups to the Main Outs with the Left and Right buttons above the Subgroup faders. The Subgroups can be used as four mono groups (Left and Right assign button pressed for each Subgroup), two stereo pairs (Left assign button pressed for Subgroups 1 and 3, and Right assign button pressed for Subgroups 2 and 4), or as two mono groups and one stereo pair.
Q: Why are my meters only working on the left side?
A: Most likely a PFL Solo button is engaged on one of the channels; the Rude Solo Light will be blinking if a Solo button is pressed. Also, the PFL Solo is a mono signal; we show this by displaying it on only the left side of the meters. Check all of your channel Solo buttons and be sure they are all disengaged. Now you should see signal on both sides of the meters and the Rude Solo Light will no longer be blinking. These two visual cues quickly remind you that you have a channel Soloed.
Q: How do I hook up stage monitors?
A: The best way to connect stage monitors to the CFX.mkII mixer is to use the Aux Sends. These allow you to create up two independent mixes for your monitors. Connect Aux Send 1 to the inputs of your monitor amps and connect the amps to the speakers. On each channel is a button labeled Pre; this should be pressed to make the Aux Sends pre-fader for that channel. This means that any fader changes you make to the channels, will not affect the monitor mixes. On each channel turn up the Aux 1 knob to send that channel to the first monitor mix. This allows you to dial in a mix just as you would with the channel faders. The Master Aux Send 1 knob controls the master volume of the stage monitor. If it is all the way down, you will not here anything from the monitor. Repeat the process with Aux Send 2 to set up your second monitor mix if necessary.
Q: Can I use multiple internal effects at the same time?
A: No. The internal effects processor allows you to choose one global effect for the entire mixer. You can then choose the amount of signal sent from any given channel to the EMAC processor. This is achieved by turning up the EFX 2 knob on the channel you would like to hear more effects on. This allows you to add a different amount of the effect to each input.
Q: How do I get the internal effects to my stage monitors?
A: By connecting your monitor amplifiers to the Aux Sends, it is possible to route the internal effects to hear them in the monitors. Set the controls in the effects section so you hear the desired effect in the Mains. There are two knobs in the effects section labeled Effects To Monitor, Aux 1 and Aux 2. Turn these up to send the effects to each Aux Send. This allows you to control the amount of effects going to the Mains and Auxes separately.
Q: How do I hook up an EQ/Compressor on my main mix?
A: The best place to connect an EQ or Compressor for your main speakers is at the Main Insert jacks. This requires the use of an Insert Y Cable, also called a Send/Return Y Cable. One end of the Y cable is a single Tip Ring Sleeve (TRS) 1/4" jack and the other ends are two Tip Sleeve (TS) 1/4" jacks; commonly, one will be labeled Tip (or Send) and the other will be labeled Ring (or Return). You will need two of these Y cables for stereo operation with a stereo processor. Plug the TRS end of one insert Y cable into the Left Main Insert. Connect the end labeled Tip into the left input of your processor and the end labeled Ring into the left output of your processor. Do the same with the second Y cable for the Right Main Insert. The Main Inserts tap the signal just before the master fader so the signal will travel from the mixer to the processor and back to the mixer before it reaches the main fader. This setup allows the processor to always see a full strength signal regardless of how you change your master fader, giving you much better operation, especially if you are using a compressor. Another advantage of this method is that if you have a problem with your processor in the middle of a performance, you can quickly remove it from the insert jacks and continue the show. You can use this same method to insert a device on a mono channel by using the Channel Insert jacks.
