SCHOEPS VMS 5 U - Manual (Page 8)

with a capacity of 3.5 Ah can power
the VMS 5 U for about 12 hours.
9-Volt transistor radio-type batteries
have excessive internal resistance and
insufficient capacity; they cannot be
used.
Please note: When running on
external batteries, during any longer
pauses (or at the end of a recording)
the unit should be switched off and
the external batteries disconnected.
Simply turning the unit off would not
prevent draining the external batteries,
since a residual current of about 40
mA is drawn from any external power
source. And disconnecting the external
power connector without switching
the unit off would cause a switchover
to any internal batteries, drawing the
full operating current from them.
5. Connecting microphones
The VMS 5 U can be used with 48
Volt phantom powered microphones
or with microphone capsules and the
active Y-cable of the SCHOEPS
"Colette" series. A switch (<19> on
page 3) on the back of the unit selects
one of these two types of inputs.
If the setting of this switch must be
changed while the unit is in use, please
lower the headphone volume level or
remove your headphones temporarily.

Connecting 48-Volt phantom pow-
ered studio condenser microphones
For the highest-quality, lowest-noise
recordings, use condenser microphones
with a sensitivity of at least 8 mV/Pa.
Turn the unit off and connect the
microphones to the inputs (<16> on
page 3) on the back of the unit. The
input selector switch <19> must be in
its downward position (pointing to the
words "Made in Germany"). The "P48"
switch <11> must be in the "ON" posi-
tion for phantom powered microphones.
Then the unit can be powered on.
For ordinary stereo recordings (not
M/S), channel I is usually the left chan-
nel while channel II is usually the right.
For M/S recordings, the "mid" micro-
phone (e.g. a forward-facing cardioid
or supercardioid) should be connected
to channel I, while the "side" (figure-8)
microphone should connected to
channel II.
Connecting SCHOEPS micro-
phones with an active Y cable
If the recording environment is rela-
tively free of interfering signals, it is
also possible to use an unbalanced
cable such as the SCHOEPS
KCY 250/5I. An input for this type of
cable is available on the back of the
unit <15>.
To use this input, turn the unit off,
attach the cable to the VMS 5 U and
attach two SCHOEPS Colette-series
capsules to the cable. The input selec-
tor switch <19> must be in the "KCY"
