hi folks, I just won an e-bay auction for 6 Bogen MM-S mic preamp modules and I need a schematic for them so I will know how to hook them up....i guess I"ll need to build a PSU for them so i will need to know the supply voltages and what the pin connections are ...(i believe they have a card type of interface simular to a PCI card)....
i looked all over then net for one and all I could find were the preamp specs.....
here are the specs that I found.....
MMS
The transformer-balanced, low-impedance microphone pre-amplifier shall be a Bogen Model MMS, or equivalent. Input sensitivity for rated output (100mV) shall be 250mV, and maximum gain shall be 52dB. The frequency response shall be 20Hz to 20kHz, ±1dB, with distortion less than .3%, and noise floor of -75dB. It shall have screwdriver-adjustable low- and high-frequency cut filters providing an action of -3dB @ 400Hz and @ 5kHz, and a separate gain control with an adjustment range of 25dB.
The module shall be capable of providing phantom power to a condenser microphone, enabled by means of a printed circuit board jumper. Screw terminals shall be provided for microphone connection.
I know these probably aren"t the best Mic preamps but I got them for cheap ($1 for all 6) and I need a little color in my recording chain so i figured these might add a bit of transformer Mojo and seem like a good project......
thanx for any help you can give.....
Cheers
