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.

Headphone Monitoring

• 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.
