I am looking to build a preamp for a project and have a microphone with the specs given below that I require to get to the right level before it enters a Behringer FCA1616 (specs also given below). Could anyone point me in the correct direction for calculating the gain needed to get the levels to match.
Specs:
Behringer FCA1616:
-Dynamic Range: 102dB A-weighted.
-Impediance: 1Mw.
-Max. Input level: +14dBu.
-Pad attenuation: 15dB.
Mic1:
-Sensitivity: -190dB re: 1V/μPa (+/- 4dB 20Hz-4KHz)
-Useful range: <1 Hz to >100KHz (approx. at 100KHz = -220dB re: 1V/μPa)
-Capacitance: 25nF
-Polar Response: Omnidirectional (horizontal)
-Operating depth: <80 meters
-Dimensions: 25mm x 46mm
-Mass: 105 grams
-Specific Gravity: 5.3
Mic2:
-Sensitivity: -218dB ±3dB (at 250Hz)
-Useful range: 1 Hz to 250KHz(+2, -4dB)
-Capacitance: 3nF
-Polar Response: Omnidirectional (horizontal)
-Operating depth: 1000 meters
-Dimensions: 25mm x 46mm
-Mass: 1.6 kilograms (including cable)
Thanks,
Greg.
