The FEUR FU-603 is a cardioid dynamic vocal microphone with a 70 Hz to 15 kHz frequency response, 600 ohm output impedance, a black matte body and black grille, a 3-pin male XLR connector and pin 2 wired positive. It weighs 0.75 lb and ships with a carry case.
The house microphone. Built to be bought by the half dozen and handed to whoever walks in.
Every venue, school, church and rehearsal room needs a stack of workhorse microphones that nobody worries about. Something to hand to a guest speaker, put on a guitar cabinet, drop on a stand for announcements or throw in the van without a second thought. The FU-603 is that microphone.
The 70 Hz to 15 kHz response starts higher in the bass than a premium stage vocal microphone, and that is deliberate at this level. Rolling off below 70 Hz keeps stage rumble, HVAC noise and handling thumps out of the signal before they reach the console, which matters more in an untreated room than the last few hertz of extension.
Output impedance is 600 ohms with sensitivity at minus 54 dB, plus or minus 2 dB, at 1 kHz. Polarity is standard, positive pressure on the diaphragm producing positive voltage on pin 2, so it phases correctly alongside any other properly wired microphone in a multi-mic setup.
At a Glance
| Type | Dynamic |
| Polar Pattern | Cardioid, unidirectional |
| Frequency Response | 70 Hz to 15 kHz |
| Sensitivity at 1 kHz | Minus 54 dB, plus or minus 2 dB |
| Output Impedance at 1 kHz | 600 ohms, plus or minus 30 percent |
| Case Finish | Black matte body, black grille |
| Connector | 3-pin XLR male |
| Polarity | Positive voltage on pin 2, IEC 60268-4 convention |
Who Is the FU-603 For?
Schools, houses of worship, rehearsal rooms, community theaters, venues that need spare microphones and anyone building a first PA. It is the microphone you buy several of.
Does It Need Phantom Power?
No. It is dynamic, so it takes no phantom power and no battery. Any standard XLR microphone input drives it.
What Comes in the Box?
The microphone, a microphone clip and stand adapter, a zipper storage pouch and the user manual. KIT versions add a boom stand adapter and a carry bag. Package contents can vary by region, so call 844-687-4208 if you need it confirmed for your order.
Is It Wired in Standard Polarity?
Yes. Positive pressure on the diaphragm produces positive voltage on pin 2, which is the industry standard. It will phase correctly with other properly wired microphones.
Can I Use It on Instruments?
Yes. A cardioid dynamic handles guitar cabinets, snare drums, brass and percussion well. The response is voiced for vocals, but the pattern and the tolerance for high SPL make it useful across a stage.

Why FEUR?
FEUR was founded in Germany by a team of engineers and sound specialists who set out to make professional audio equipment that performs at a high level and stays within reach of the people who actually use it every week. Where most of the industry aims either at high-end studio work or at the bottom of the market, FEUR builds for the working middle: independent artists, houses of worship, schools, mobile operators and installed systems that need gear to show up and work every week.
Frequently Asked Questions
Is this a genuine FEUR product?
Yes. Victory is a veteran owned dealer in Miami and units ship new in original packaging.
Does the FU-603 come with a warranty?
Yes. It carries the FEUR manufacturer warranty against defects in materials and workmanship. Keep your invoice and call us at 844-687-4208 if you ever need service.
Will it work with a standard microphone cable?
Yes. Standard 3-pin male XLR, so any balanced microphone cable works.
How does it compare to the FU-PRO7?
The FU-PRO7 is the higher specification microphone, with a die-cast body, wider 60 Hz to 15 kHz response and a hotter output at 400 ohms. The FU-603 is the utility option, lighter and simpler, and it does the job.
Can I order these in quantity for a school or church?
Yes. Call us at 844-687-4208. Multi-unit orders of utility microphones for schools, churches and venues are something we handle by phone.
Which FEUR microphone is best for live vocal performance?
All FU vocal microphones feature cardioid polar patterns optimized for live stage use. The FU-603 and FU-629 offer 600 Ω output impedance for ideal compatibility with professional mixing consoles. The FU-658SW adds an on/off switch for presenters who frequently mute between speaking moments.
Do these microphones require phantom power?
No. All FU dynamic microphones are passive devices requiring no external power supply or phantom power from the mixing console.
What polarity standard do FEUR microphones follow?
All FEUR microphones adhere to IEC 60268-4 polarity convention: positive acoustic pressure on the diaphragm produces positive voltage on pin 2 of the XLR output, ensuring phase compatibility across professional audio systems.
