Its switchable Ultra-HiZ input offers up to an impressive 10 Mohms of input impedance, preserving the natural tone, dynamics, and full frequency response of passive guitar pickups, piezo-equipped instruments, and other high-impedance sources. Selectable impedance settings of 10 Mohms, 100 kohms, and 10 kohms allow the input characteristics to be matched to virtually any instrument or application.\u003c\/p\u003e\n\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003eSwitchable Ultra-HiZ input with up to 10 Mohms of input impedance\u003c\/li\u003e\n\u003cli\u003eSelectable input impedance: 10 Mohms, 100 kohms, 10 kohms\u003c\/li\u003e\n\u003cli\u003ePreserves the natural character, dynamics, and frequency response of sensitive sources, including passive guitar pickups and piezo transducers\u003c\/li\u003e\n\u003cli\u003eSwitchable DYNAMITE gain boost delivering 15 dB or 30 dB of ultra-clean gain\u003c\/li\u003e\n\u003cli\u003eSwitchable attenuation pad: 0, -15, -30 dB\u003c\/li\u003e\n\u003cli\u003ePOLAR switch allows signal polarity inversion\u003c\/li\u003e\n\u003cli\u003eShielded heavy-duty transformer and innovative on + Ground Lift circuitry\u003c\/li\u003e\n\u003cli\u003eHigh headroom, low distortion, and exceptional sound quality\u003c\/li\u003e\n\u003cli\u003eMinimizes hum and radio frequency interference\u003c\/li\u003e\n\u003cli\u003eNon-slip mounting pad included for studio use\u003c\/li\u003e\n\u003cli\u003eHook-and-loop mounting pads included for pedalboards and gig racks\u003c\/li\u003e\n\u003cli\u003eMount up to four units on a standard 1U rack shelf; screws included\u003c\/li\u003e\n\u003cli\u003eSecure stackable design for multi-channel setups\u003c\/li\u003e\n\u003cli\u003eMatte-black stealth finish\u003c\/li\u003e\n\u003cli\u003eSolid steel enclosure\u003c\/li\u003e\n\u003cli\u003eFront and rear +48 V LEDs for phantom power indication\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\n\u003cp\u003eTo further maximize signal quality, the FCA1 features an integrated DYNAMITE gain boost delivering 15 dB or 30 dB of ultra-clean gain directly at the source. By increasing the signal level before long cable runs or electrically noisy environments, the FCA1 helps preserve every nuance of your performance from instrument to mixing console.\u003c\/p\u003e\n\n\u003cp\u003eAt the heart of the FCA1 is a custom-designed, shielded heavy-duty transformer providing galvanic isolation, delivering exceptional headroom, low distortion, and outstanding noise rejection. Together with the innovative on + Ground Lift circuitry, hum, ground loops, and radio-frequency interference are effectively minimized, ensuring clean, transparent audio in even the most challenging live and studio environments.\u003c\/p\u003e\n\n\u003cp\u003eBoth models feature switchable attenuation pads for handling high-output sources such as guitar and bass amplifiers without distortion, while their custom transformers maintain exceptional headroom and signal integrity under demanding conditions.\u003c\/p\u003e\n\n\u003cp\u003eDesigned with versatility in mind, the FCA1 offers a wide range of mounting options. A non-slip mounting pad is included for desktop and studio use, hook-and-loop pads allow secure installation on pedalboards and gig racks, and up to four units can be mounted in a single 1U rack space using the supplied mounting screws. Its stackable design also makes multi-channel stage setups neat, secure, and easy to configure.\u003c\/p\u003e\n\n\u003cp\u003eIts compact footprint and heavy-gauge steel construction make the FCA1 ideal for professional stage, studio, and touring applications. The robust all-metal design provides exceptional durability, while the discreet matte-black stealth finish blends seamlessly into any stage, studio, or pedalboard setup. Front and rear +48 V status LEDs provide instant phantom power indication from either side, making operation even easier in any environment.\u003c\/p\u003e\n\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\n\u003ch4\u003eSPECIFICATIONS\u003c\/h4\u003e\n\n\u003cp\u003e\u003cb\u003eGeneral\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eType: Active\u003c\/li\u003e\n\u003cli\u003eFrequency Range: 10–80,000 Hz (-0.3 dB)\u003c\/li\u003e\n\u003cli\u003eInput Impedance, ATT PAD 0 dB: 10 Mohms \/ 100 kohms \/ 10 kohms\u003c\/li\u003e\n\u003cli\u003eInput Impedance, ATT PAD -15 dB: 12 kohms \/ 12 kohms \/ 12 kohms\u003c\/li\u003e\n\u003cli\u003eInput Impedance, ATT PAD -30 dB: 10 kohms \/ 10 kohms \/ 10 kohms\u003c\/li\u003e\n\u003cli\u003eAttenuation Pad: 0 \/ -15 \/ -30 dB\u003c\/li\u003e\n\u003cli\u003eMax Input Level (0.5% THD), ATT PAD 0 dB: 8 dBV (2.75 V)\u003c\/li\u003e\n\u003cli\u003eMax Input Level (0.5% THD), ATT PAD -15 dB: 24 dBV (15 V)\u003c\/li\u003e\n\u003cli\u003eMax Input Level (0.5% THD), ATT PAD -30 dB: 39 dBV (87 V)\u003c\/li\u003e\n\u003cli\u003eGain: 0 \/ +15 \/ +30 dB\u003c\/li\u003e\n\u003cli\u003eOutput Noise Level (JIS-A), GAIN 0 dB: 1.4 µV\u003c\/li\u003e\n\u003cli\u003eOutput Noise Level (JIS-A), GAIN +15 dB: 6.4 µV\u003c\/li\u003e\n\u003cli\u003eOutput Noise Level (JIS-A), GAIN +30 dB: 29 µV\u003c\/li\u003e\n\u003cli\u003ePowering: 48 Volts Phantom Power according to IEC 61938\u003c\/li\u003e\n\u003cli\u003eElectrical Output Impedance: 60 ohms\u003c\/li\u003e\n\u003cli\u003eRecommended Load Impedance: Greater than 1k ohms\u003c\/li\u003e\n\u003cli\u003eCurrent Consumption: 7.2 mA\u003c\/li\u003e\n\u003cli\u003eSystem Requirements: 48V Phantom Power required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cb\u003eConnectivity\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eInput: 6.3 mm (1\/4 in.)
