Microphone Channel Gain Controls1--4: At 0 position, mi- crophone channel is removed from operation. Turning controlclockwise activates microphone channel and allows adjust- ment of microphone level. 2. Input Normal Green LED: Should flicker with normal speech levels. 3. Input High Red LED: Should flicker only on loud speech peaks. 4. Flat ( )/Low--Cut ( ) Slide Switches: Provide low--fre- quency rolloff to reduce undesirable low--frequency signals such as wind noise. 5.MASTERRotary Control: Determines the level of the com- bined input signals at Mic/Line, Tape and Phones outputs. PULL FOR 1 kHz TONE position activates 1 kHz tone oscilla- tor (tone level is determined by Master control setting). Oscilla- tor signal appears at all outputs. When oscillator is not in use, knob should be pushed in. 6.PEAK/VUOutput Level Meter: Meter function is selected by adjacent PEAK/VU slide switch. In PEAK switch position, me- ter indicates peak signal levels. In VU position, it indicates av- erage signal levels, simulating a true VU meter. 7.BATTERY TESTMomentary Slide Switch: Operates in con- junction with PEAK/VU Meter to indicate battery condi- tion.With POWER switch on and switch in momentary--on po- sition, new set of batteries lights all green LEDs. Number of green LEDs lit indicates approximate battery life remaining when alkaline batteries are used. NOTE:POWER LED begins flashing when total battery supply voltage drops to 10 Vdc (one green LED lit). 8.MANUAL/AUTOSlide Switch: Selects manual or automatic microphone operating mode. In MANUAL position, unit oper- ates as a conventional microphone mixer. In AUTO position, unused microphones automatically turn off.

3 9.LIMITER INSlide Switch: Activates fast--acting, peak--res- ponding limiter circuit to cut overload distortion during loud program intervals without affecting normal program levels. The red limiter LED indicates limiting action. 10.PHONES 1/4--inch and 3.5 mm Phone Jacks: Permit moni- toring mixer output through most stereo or mono headphones. PULL FOR MONITOR switch applies signal from rear--panel MON IN 3.5 mm phone jack to headphones amplifier. When switch is activated, mixer output signal does not appear in headphones output. PHONES rotary control determines headphone level in either case. 11 .POWERSlide Switch: Applies ac or battery power to mixer circuitry. Adjacent green LED indicates power--on status and, in battery operation, flashes when total battery voltage drops to 10 Vdc. 12.100 -- 120 VAC, 50/60 Hz 8W3--Pin Power Connector: For connection to 100 to 120 Vac, 50/60 Hz power outlets (230 Vac in the FP410E). 13.OUTPUT3--Pin Male XLR Connectors: For connection to one or two amplifiers, recorders or other mixers. Output signal levels are individually switchable to Line level or low--impe- dance Mic level by adjacent individual MIC/LINE slide switches. Both jacks provide the same signal information but are electrically isolated. 14.TA P E O U T3.5 mm Phone Jack: Provides output signal to feed unbalanced aux--level inputs of most tape recorders and amplifiers. 15.LINK IN/OUT8--Pin miniature DIN Jacks: Using link cables, these jacks permit virtually unlimited number of FP410 mixers to be stacked to achieve additional input capacity. Jacks carry audio signals, MaxBus and Last Mic Lock--On in- formation. 16.MON IN3.5 mm Phone Jack: Sends external Aux or Line-- level source to headphones amplifier without interrupting other mixer functions. Jack is activated by pulling front--panel PULL FOR MONITOR knob outward. 17.PHANTOM ON/OFFSlide Switch: Controls application of 14 Vdc phantom power for condenser microphones to all in- puts. With switch on and INPUT MIC/LINE switches in MIC po- sition, +14 Vdc is applied to pins 2 and 3 of each input XLR con- nector. NOTE: Phantom power can be internally set to 48 Vdc (seeModifiable Functionssection). When using other than Shure condenser microphones, verify that voltage and source resistance requirements are compatible (seeSpecifications). 18.INPUT 1 -- 4Female 3--Pin XLR Connectors: Permit con- nection to balanced, low--impedance microphones or line--le- vel sources. Adjacent MIC/LINE slide switches adjust inputs to match source levels. 19. Battery Compartment: Accepts two 9--volt batteries for re- mote operation or as automatic backup in the event of ac pow- er failure. INSTALLATION AND OPERATION Mixer Installation Install the FP410 as follows. If the unit is to be placed on a horizontal surface, attach the four supplied bumpers to the cor- ners of the chassis bottom to prevent marring the surface. If the FP410 is to be rack--mounted in a standard 483 mm (19--inch) audio equipment rack, remove the two Phillips headscrews from each FP410 side panel, place the rack ears in position at the sides (rack--mount holes facing forward), and secure the ears with the previously removed Phillips head screws. NOTE: The rack ears are asymmetrical; thewiderear should be on your right (as you face the front panel) to permit access to the battery compartment while the FP410 is in the audio equipment rack. Install the rack--mounted FP410 in the equipment rack and secure it with the four supplied rack-- mount screws. Make electrical connections as follows. 1. For battery operation, compress the release latches of the battery drawer with thumb and forefinger, and withdraw the drawer from the compartment. Observing battery polarity markings, insert two fresh 9--volt batteries in the drawer slots. With the Power switch on, slide the Battery Test switch to the right to determine battery condition. IMPORTANT: Battery operating life is reduced when microphones are phantom--powered-especially by 48 Vdc phantom power- ing. For ac operation, connect the power cord to a 100 to 120 Vac, 50/60 Hz source (FP410E: Connect to a 230 Vac, 50/60 Hz source). 2. Connect the microphones and/or line--level signal sources to the Mic Input connectors (use conventional 2--conductor shielded cables). Adjust Mic/Line switches as required for incoming signal level. 3. If phantom--powered condenser microphones are used, turn on the FP410s Phantom Power switch. NOTE: With condenser microphones other than Shure, verify that volt- age and source resistance requirements are compatible. 4. Connect one or both of the FP410 Outputs to the following mixers, amplifiers or recorders. Make certain each Output Mic/Line switch is in the proper position for the desired out- put levels. 5. If an unbalanced aux--level output is needed, connect it to the Tape Out jack. 6. If additional FP410 mixers are to be linked to increase the number of microphone inputs, connect them by means of the Link In and Link Out jacks. Connect the LINK OUT of the first mixer to the LINK IN of the next mixer, and so on. Leave the LINK IN jack of thefirstmixer and the LINK OUT jack of thelastmixer unconnected. NOTE: Jacks are for linking only, not for audio inputs or outputs. 7. If headphone monitoring of the FP410 mixed signal is re- quired, connect mono or stereo headphones to one of the front--panel Phone jacks ( 1/4--inch or 3.5 mm). Adjust the Phone control knob for the desired loudness (after setting the microphone Channel and Master Gain controls accord- ing toOperationsection). 8. To monitor an external signal source, connect it to the rear-- panel Mon In jack and pull the Phones control knob outward. Adjust the Phones control and/or the external source level control for the desired loudness.
