I think that the
pin assignments might be different from Schoeps bodies and that is why the Lemosax fails to power the capsules properly.
16. SPECIAL VERSIONS
SX-M2/LS
Designed for use by sound engineers, working frequently with the same pair of condenser or electret microphones, this version provides the same high quality amplification and features as the SX-M2.
The difference between the two versions is that the SX-M2/LS allows the user to directly connect the capsules without the microphone body thus creating a significant diminution of power consumption.
Technical changes
To be able to place the electronics of the microphone body inside the SX-M2/LS, LEMO connectors are used instead of the NEUTRIK XLR for the microphone inputs.
LEMO in L: Shield = Gnd, Pin 1 = +10V, 2 = +48V, 3 = signal in
LEMO in R: Shield = Gnd, Pin 1 = +10V, 2 = +48V, 3 = signal inThe SX-M2/LS can be used for all condenser or electret microphones having the possibility of changing the capsules on the microphone body, such as: Colette series of Schoeps, Blue Line of Sanken, or the similar line of Neumann.
It is important for these kind of microphones to use a good quality active cable. When buying the cable from a microphone manufacturer, do inform them that the amplification electronics often used in the cables is not required.
I was digging around and found that someone else had a question about running their Neumann cables with the Lemosax and here is what a couple of people answered:
Question:
I would like to attempt to make my LC3KA cables into the older style LC3 cables for use with the Lemosax. I would like to know what the internal cable designations of the LC3KA are so as to correctly wire the lemo connector. Does anyone know? Also, the pin designations on the lemosax are:
Shield = Gnd, Pin 1 = +10V, 2 = +48V, 3 = signal in
The Ak capsules use a 48V output for polarization, correct?
Answer:
Dear Mr. Liu,
the wires in the LC3 are assigned in the following way:
Shield = GND = 0V
white = 10V = outer ring contact
green = 50 V polarization voltage (48V is fine as well) = middle ring contact
brown = signal = central pin.
Please check polarity of the signal, e.g. comparing with standard wired mics. The AKs need -50V to produce correct polarity in unbalanced connections, so probably you will have to invert polarity when mixing with other signals.
Best regards,
Martin Schneider / Neumann Mic. Development
In addition the only information that I could find on old Schoeps cable pin assignments are as follows:
CMC -U XLR-3 connector with pin1 = GND, pin2 = + signal, pin 3 = - signal
CMC -D Tuchel-3 connector with pin1 = + signal, pin2 = GND, pin3 = - signal
CMC -F Sogie-7 connector (French market only) with pin H = + signal, pin D = - signal, pin C = B = GND
CMC -L Lemo-3 connector plus a constant current diode for P24 .. P48 powering (Austrian market only)
