Sayfayı Yazdırno matrixing takes place on the input signals; it is then possible to record either a conventional
stereo signal, or to record "M/S" sources "as they are"
• In on position (switches to the right), the "M/S" signal is decoded and converted to conventional
L/R stereo. With M/S decoding on, the PRE outputs on its left channel a mixed signal of both
microphones (1+2 or M+S) and a substraction of both microphones on the right channel (1-2 or M-
S).
TIP: 2 switches are volontary used to enable M/S decoding. By switching only the "M" channel, the
PRE will output a mix of microphones 1 and 2 on the left channel but will still output microphone 2
on the right channel. This setup is very usefull when a mono mix of both channels is required.
AUTONOMY:
The autonomy of the AUDIOROOT
microphones connected to the unit. Typical autonomy with 2 iPOWERUS 520mAh lithium-polymer
batteries and 2 SCHOEPS CMC64Ug microphones is 5 hours. This autonomy rises with dynamic
microphones, alcaline batteries or an external power source.
AUDIO INPUTS AND OUTPUTS:
The 2 "LEFT" and "RIGHT" mini-XLR input connectors are disposed at the rear of the unit. These
inputs are transformer balanced with an input impedance of 5Kohms. Equipement with asymetrical
outputs can be connected to the PRE by bridging pins 1 and 3 and connecting them to ground.
The preamp's stereo output is also disposed at the rear end of the PRE. This output is asymetrical
and is directly compatible with many stereo asymetrical inputs such as those found on small handheld
flash recorders. The user can connect this stereo output to any symmetrical input by using the stereo XLR
output cable provided with each PRE.
Each microphone preamp is provided with 1
cables :
•
2 XLR mic input cables
•
1 stereo XLR ouput cable
•
1 stereo mini-jack output cable

PRE depends directly from the power source (battery type) and
PRE CABLE KIT which includes the following
mating connector reference is
Switchcraft 760K. The PRE can be
powered via this connector with an
external voltage of 12 to 18V. Batteries
are automatically disconnected when a
power jack is inserted into the DC input
connector. Connector polarity : inner =
+ , outer = - . The DC IN input is
protected against polarity reversal.
2 switches are purposely difficult to
access; they optionally insert an M/S
decoder on the path to the unbalanced
stereo output
