Patch in the SOLO where appropriate for your model, and select the input/ output level on the back. With gain down on the input channel, put the SOLO in Active mode (green bypass LED), then slowly raise the channel gain to the point of feedback. [. . . ] Now lower the channel level fader slightly so that the system is not on the verge of another feedback point. This is the maximum volume level that the FBXSOLO will be able to provide. Higher levels will cause uncontrollable feedback. CHANNEL INPUT LEVEL CHANNEL INPUT LEVEL 9 Finally, during sound check, adjust the Clip Level Adjust so that the red Clip LED blinks intermittently, as you would adjust the recording level of a tape recorder. The unit will clip and distort the program if the Clip Level Adjust is set too high. If it is set too low, the signal-to-noise ratio will degrade and the system may hiss. IMPORTANT: Make sure Turbo mode is OFF -- Clip LED NOT flashing! 15 HOW TO USE THE "LOCK FIXED" FEATURE In certain situations the FBX may mistake music for feedback and drive the fixed filters deeper than necessary, like in a church with a pipe organ or during a performance with a great deal of intentional sustained electric guitar feedback. You may prevent the fixed filters from deepening beyond their initial depth by pressing the Lock Fixed button on the front panel AFTER setting the fixed filters as described previously. The Lock Fixed LED will light to indicate that the FBX is in Lock Fixed mode. The fixed filters will stay locked until you press the Lock Fixed button again. In almost every situation, it is best to lock the fixed filters right after the initial setup. LIMITING TOTAL NUMBER OF ACTIVE FILTERS You may choose to limit the total number of active filters for each application by using the Lock Fixed button. For example, if you wish to use only three fixed and one dynamic filter, set the FBX so there are seven fixed and one dynamic filter. Then during the setup procedure, simply press the Lock Fixed button after setting the first three fixed filters. The remaining four fixed filters will be locked in their zero position. SELECTING FILTER WIDTH If the SOLO is to be used for a music application, 1/10octave filters are most effective. However, in spoken word applications, such as lectures or teleconferencing, the wider 1/5-octave filters are recommended. Select the filter width using the switch on the SOLO back panel. The change takes effect only on powerup. Selecting a new width has no effect unless you power down and then power up again. ENGAGING THE NOISE GATE One outstanding feature of your FBX-SOLO is a userselectable noise gate. It acts as an automatic switch that opens a microphone only when someone is speaking directly into it. A noise gate is especially useful in systems that have a number of open microphones, such as courtrooms, conference rooms, or parliament buildings. Gating microphones greatly reduces the number of possible feedback points in the room and allows for more system gain. 16 The level that turns the noise gate on and off is called the threshold. If the level coming into the gate is greater than the threshold, the noise gate opens, and the mic is turned on. If it is less than the threshold, the noise gate closes, and the mic is turned off. You can adjust your SOLO to four different threshold levels (see diagram at left), or turn it off.
