Stereo Microphone Preamplifier with
Phantom Powering and M/S Matrix
VMS 5 U
– frequency response: 20 Hz – 80 kHz (-3 dB)
– two low-cut filters: 20 Hz (permanent) and 150 Hz
(switchable)
– switchable M/S matrix
– switch for “swapping” channels with M/S recording
– switchable 48-Volt phantom power; the ability to
disable phantom powering is important for M/S
post-production
– inputs: XLR-3F (balanced) and special socket for
Active Y-Cable of the Colette modular system
– outputs: XLR-3M (balanced); easy connection to
unbalanced inputs without loss of signal level
– can run from six internal batteries (primary or
rechargeable) or from externally supplied DC
– glitch-free, automatic switchover to internal batteries
in the event of AC power loss
– battery level meter and low-voltage warning LED
– protection from accidental overdischarge of internal
NiCads
– automatic shutoff if voltage gets too low
– headphone monitor output
– gold-plated sockets and switch contacts for long
service life
– black all-metal housing (aluminum)
Battery-operated microphone preamplifiers sometimes
have high noise figures because current consump tion
is kept limited in the interests of longer battery life. But
the VMS 5 U places hardly any such limitation on the
performance of the microphones. In addition, its fre-
quency response leaves nothing to be desired.
One of the characteristics of high-quality equipment
is durability. It may be several years before you find
out whether the potentiometers and switches on a
unit will become noisy when used. In the design of
this product, SCHOEPS placed the primary emphasis on
reliability and durability, choosing all its components
(such as switches and sockets with gold-plated con-
tacts) accordingly.
The unit shuts itself off if the battery voltage falls
beneath a certain threshold value, in order to prevent
completely draining the batteries and possibly damag-
ing circuit components.
A further quality feature is the all-metal housing,
which is unbreakable and protects against radiated
electromagnetic interference.
For increased ease of use, the lettering on the back
panel is printed upside down relative to the front panel,
so that it is unnecessary to turn the unit around in
order to read the labeling.
The VMS 5 U with its universal power supply capa-
bility and compact dimensions is equally well suited for
portable or fixed operation.
