Battery-operated microphone preamplifiers sometimes have high noise figures because current consumption is kept limited in the interests of longer battery life. But the Schoeps VMS 5 U places hardly any such limitation on the performance of the microphones. In addition, its frequency 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 contacts) 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 damaging 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 capability and compact dimensions is equally well suited for portable or fixed operation.
