FX44 Mixer Detailed Control Descriptions Section 3 Controls on the System Master Strip The System Master strip is the vertical group of controls just right of the highest numbered channel strip. This is where you set monitor and effects levels and set effects return levels. Control room source selection, talkback, and two-track playback controls are here also. 1) 12V LAMP (Mini-Lamp connector) The BNC connector labeled 12V LAMP (located at the very top of the system master strip) is a receptacle for a standard 12 volt "Mini-Lamp". This light is used to provide illumination for the console when it is used in low light conditions. It operates on 12 volts and provides an excellent source of light where house lighting is kept low. The mini-light is offered by CARVIN and may be purchased for $29.00 (specify Model G-12). 2) SEND Master Level Controls Located just below the mini-lamp connector are six knobs labeled MON 1. MON 2, EFF 3, EFF 4. EFF 5, and EFF 6. These are the SEND master level controls. The SEND master level controls set the overall output signal level that is sent to the monitor amps and outboard effects. Commonly used effects are digital reverbs and digital delays, although there are a host of other effects devices that can also be used. Buss signals from the channels are summed together and the overall level is set by the SEND Master level controls. From these controls the signal is routed to the corresponding rear panel E F F SN D jacks. Monitor amp input level controls should be set at maximum (or at least half maximum). The overall volume of the monitor speakers is then controlled from the monitor SEND master control(s) at the mixer. In general you may require two or even more separate monitor mixes to satisfy the needs of the performers. (For example: The singer usually wants to hear mainly vocals in his monitor mix but the drummer may want to hear more bass and less vocals in his monitor mix.) Effects units may or may not have an input level control. If your unit has an input level control it should be set relatively high (at least half of the maximum setting) when used with the FX44 mixers. Then you can control the overall input level at the effects unit from the appropriate SEND master control. After you have connected the signal from the mixer to your effect unit, adjusted its levels, and dialed in its desired parameters, you will have to return the effects output signal back to the mixer. Do this by patching the output of the effects unit into one of the EFF RTN inputs at the mixer. (see section 5 and "Effects Returns" below) 3) METER Switches These switches determine which signals will be shown by the meters on the meter panel. The meters normally show the signal level at the sub group outputs but can be switched to show the output ley e.s of MON 1 and MON 2, or the 2 TRACK left and right outputs. 4) +48 VDC PHANTOM Power Switch The +48VDC PHANTOM power switch (when depressed) will provide a 48 Volt D.C. voltage to pins 2 & 3 of the mic inputs of the console. This voltage is required to operate most "condenser" type microphones. Without 'Phantom Power" you simply would not be able to use these types of microphones with your console unless you purchase an outboard power supply to provide this voltage. The red LED located just above the switch illuminates to indicate that phantom power is switched on. If most of your microphones are dynamic types (not requiring Phantom power) and you are also using one or more condenser type miss, you will need to switch on the phantom power. This will not affect the operation of normal balanced dynamic microphones. If you are not using any microphones that require phantom power then we recommend that you leave it switched off. Note: Before using the Phantom power switch with wireless microphones check to be sure your mic is tolerant of Phantom Power. It is best to consult with the microphone's manufacturer to be sure. 3-5
