MODEL FP410

FIGURE 1

Selectable Off--Attenuation control for seamless operation

Automatic gain adjustment as additional microphones are activated

Defeatable “Last Mic Lock--On” circuit keeps at least one mi-

crophone on at all times—maintains acoustic ambiance and prevents confusing background sound changes

Wide, flat frequency response and low distortion up +18 dBm output

Linking capability for systems containing over 25 mixers and over 100 microphones

LED indication of microphone channel mix levels, output level, and limiter action

Automatic muting prevents annoying thumps and loud- speaker damage when unit is turned on and off

Transformer--balanced inputs and outputs switchable to line-- or microphone--level

Separate monitor input and tape output (aux--level) jacks

Front--panel headphone monitor jacks with level control

Front--panel auto--disable switch for manual operation

Operates from ac mains voltage or two 9 V batteries

Switchable 14 V and 48 V phantom powering for condenser microphones

Underwriters Laboratories Listed and Canadian Standards Association listed as Certified (FP410 only)

CONTROLS, CONNECTORS, INDICATORS

(See Figure 1)

1.Microphone Channel Gain Controls 1-4: At “0” position, mi- crophone channel is removed from operation. Turning control

clockwise 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.MASTER Rotary 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/VU Output 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 TEST Momentary 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/AUTO Slide 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.
