High Quality Inputs and Outputs
The FP33 features Balanced, metal XLR input and output connections, switchable bettween Mic and Line level signal. In addition the FP33 features 3.5mm Monitor input and Tape output jacks.
Quiet Audio Signal
Transformer balanced inputs and outputs result in superior rejection of RFI and electromagnetic hum.
48 & 12 Volt Phantom Power
Both 48 Volt and 12 Volt Phantom power is supported allowing up to 8 hours of use on 2 single 9 Volt batteries. 48 and 12 Volt Phantom Power allows compatability with a wider variety of microphones.
Mix Bus Output
The Mix Bus output jack allows users to cascade multiple FP33 mixers for simultaneous use. Also allows tandem use with the Shure FP32A.
Professional VU Meters
Professional analog VU meters prove much more durable against the eliments than LED, LCD or Flourescent meters. The meters feature timed or toggled backlighting and are multifunctional.
Built In Tone Oscillator
The FP33 provides a 1kHz test tone oscillator for callibration of tape machines, meters etc.
Isolated Two-Way Talk Back
Isolated two-way talk-back using Monitor In and modified Slate Mic/Tape Out jack.
4 Headphone Monitor Modes
Headphone Monitor switch allows monitoring of Left, Left + Right (Mono), Right and Stereo audio signals. Perfect for isolating either “Mid” or “side” signal when using stereo microphones.
Compact Rugged Design
The Compact rugged plated metal chassis is made to withstand extreme heat and cold for full operation under harsh conditions.
