CONTROLS AND CONNECTORS
On�Off Switch: applies power to the FP16A circuitry Power LED: Indicates unit is on. Input Gain Screwdriver Control: adjusts input signal level. Output 1-6 Screwdriver Control: adjusts individual output channel signal levels. Norm LED: indicates when internal signal level is approximately 25 dB below clipping. Overload LED: indicates when internal signal level approaches clipping. Three-Pin XLR 1-6 Output Connectors: provide for connection to either low-impedance microphone or line level inputs of power amplifiers, mixers, or other signal processing equipment. Mic/Line 1-6 Slide Switches: select microphone or line level output signal levels. Phantom On-Off Slide Switch: applies 27 VDC (nominal) phantom power to pins 2 and 3 of the input connector for use with condenser microphones. IMPORTANT: Make certain any condenser microphone used is compatible with the FP16A phantom circuit, and that the FP16A input Mic/Line switch is in the Mic position. Do not turn the Phantom switch on when using unbalanced low-impedance microphones; objectionable hum will result. Turn the Phantom switch off when phantom power is not required. Three-Socket XLR Input connector: provides for connection to microphone or line level input signal sources. Input Mic/Line Slide Switch: selects microphone or line-level input signals. Link In, Out Phone Jacks: provide for connecting more distribution amplifiers for additional outputs, or adding external equipment such as equalizers, compressors, or limiters. When connecting two or more FP16As together for additional outputs, connect the Link Out jack of the "master" unit to the Link In jacks of the others. Any number of FP16As can be tied together in this way. The Link In jack is input-only, and has switching contacts to disconnect the input signal amplifier from the output channel volume controls. Connect an equalizer, limiter or compressor to the FP16A by connecting the FP16A Link Out jack to the external unit's input, and the external unit's output to the FP16A Link In jack. Signals at the Link jacks are typically 10 dB below line level. The Link In input impedance is greater than 20 k� and may be considered a bridging impedance.
