General Description

The Shure FP24 is a studio-quality two-channel, portable, stereo
microphone mixer. With assignable L-C-R inputs, built-in slate mi-
crophone, 1 kHz tone oscillator, and headphone monitor, the FP24
is extremely flexible. Its impressive audio performance and com-
prehensive features make it suitable for the front end of any studio
or field production system. Radio, television, and film production
engineers will especially value its compact size, sunlight-readable
LEDs, and rugged mechanical and electrical construction that
make it able to withstand extremes in the field.
Features
High Performance Microphone Inputs
Maximum of 66 dB of gain (each input).
Premium Lundahl input transformers provide superior audio
quality and freedom from interference problems.
Sealed, conductive plastic potentiometers for long life and
reliable gain adjustment.
Phantom power, selectable between 48 volts and 15 volts.
Switchable low-cut filters with 80 and 160 Hz corner
frequencies, 6 dB per octave. Filters are inserted prior to
any active circuitry to maximize headroom.
Inputs assignable to Left, Center (both left and right) or
Right
Audio Performance
Dynamic range exceeding 110 dB.
10 Hz to 50 kHz audio bandwidth.
Exceptionally low distortion characteristics.
Discrete, 6-transistor, balanced output drivers provide signal
integrity over long cable runs.

Switchable between program audio or external (stereo) tape
returns.
High current headphone output has level control and peak
indicator.
Level Metering
Dual-color LEDs indicate clipping and limiter activity for
each channel.
Sunlight-readable, seven segment GaN LED output meters.
3-position LED brightness switch (intensity selector).
Audio Limiters
"Unclippable" input peak limiters with adjustable limiter
threshold (each input).
Dual mono or linked stereo limiter operation.
Flexible Powering
Internal power from two AA batteries with easy access
battery compartment.
Chassis-isolated 5 to 14 VDC input for easy external DC
powering.
Power LED indicates low battery power.
Trouble-Free Design
High-strength, extruded aluminum chassis with protective
metal end panels withstands punishing field conditions.
All-metal connectors mount directly to the chassis for
durability and RF immunity.
Free from "Pin 1" grounding problems.
RF filtering on all inputs and outputs.

    *Threaded coaxial connector provided for use with power sup- plies not equipped. For instructions on how to solder this connec- tor to a Shure PS20, see Figure 5. Power LED: Dual-color LED indicates following: Green—external DC power or good battery.

    Mic Inputs Transformer-balanced XLR inputs accept microphone level signals. Pin 2 = hot, Pin 3 = cold, Pin 1 = ground. NOTE: You can use Shure A15LA line adapters to con- nect balanced, line-level sources to these inputs. Phantom Power Three-position switch selects either 48-Volt or 15-Volt phan- tom power for both inputs.

  • Page 4: Operational Notes

    High Pass Filter To remove excess low-frequency energy in the audio signal, use either of the two high pass (low cut) filter settings on the FP24. Use the 80 Hz position for most applications, such as recording speech, music, and ambient sound. The 160 Hz position is useful for en- hancing speech clarity and reducing wind-noise.
  • Page 5 This unique, two-stage topology limits the gain stage directly after the mic input transformer without changing the input imped- ance as other “at the mic” limiters do. The circuit enables the FP24 to limit in excess of 50 dB, making it very difficult to clip the unit re- gardless of the gain setting.

    NOTE: If constructing your own FP24/FP33 interconnect cable: Keep cable length to a minimum, since the interconnection is unbalanced. Be sure to drive the FP33 mix bus off of pin 2 of the FP24 since the FP24 inputs are reverse polarity with respect to FP33 inputs.
