1. GENERAL DESCRIPTION
The PA-13 is a robust small preamplifier, designed to condition ½“
polarized microphones as the C-130 model. It is also compatible with
other makes of microphones.
By virtue of its wide frequency response and low noise level, the PA-13 is ideal for
precision applications.
Because of its low output impedance the PA-13 allows to use long cables. The PA-
13 has a high input impedance that makes the microphone not to charge.
The PA-13 preamplifier together with the C-130 200 V polarised condenser
microphone are the perfect solution for multi channel systems.
2. PARTS
1. Output connector.7-pin LEMO connector for the connection of the
preamplifier.
2. Preamplifier body, Preamplifier housing where the model and the serial
number of the preamplifier are indicated.
3. Thread of the microphone.thread for the connection of the ½” polarized
microphone ( C-130).

3. USES
•Acoustic precision measurement with ½” polarized microphones.
•The general use of the PA-13 is conditioning the signal from ½“ microphones with
a high input impedance and delivering this signal with a low output impedance for
connecting to conditioning amplifiers or analysers.
•Multi Channel Systems
4. CONNECTION
1. Screw the microphone to the preamplifier. Do not screw and unscrew the
microphone with the preamplifier feed it.
2. Connect the preamplifier to an equipment with a LEMO connector (make sure
that the equipment is compatible with the pins and with the supply range of the
preamplifier) through a cable male LEMO- female LEMO. Make sure that the
connector is correctly inserted.
5. FITTING THE PREAMPLIFIER TO A TRIPOD
To adapt the preamplifier to a tripod , you should use the TR-001 adapter to fix the
preamplifier+microphone to the TR-40 tripod, thereby, the preamplifier will be perfectly fitted
to the tripod.
To do it, please follow the next steps:
1- Put the LEMO socket of the
extension cable through the TR-001.
1
2- Fix it to the adapter with a
screwdriver.

6. PRECAUTIONS
When using the PA-13, be careful with the next points:
•To screw or unscrew the microphone into position use only your hands (no tools). Do
not do it while the PA-13 is feeding it.
•This equipment only can work with the accessories mentioned in the accessories
section. In case that using a different accessories and that this causes a failure in the
equipment, would not be responsible of this failure. Then the equipment
will lose its warranty.
•When connecting and disconnecting the LEMO-LEMO cable, do it by holding the
preamplifier by the connector never by the cable, as it is shown in the next figure.
3- Screw the adapter into the
tripod (the adapter thread is
Whitworth ¼’’)
3
4- Plug the preamplifier. Make
sure the slit of both LEMO
connectors fits.
