Very High Quality Stereo Microphone Preamplifier
with Phantom Powering and M/S MatrixVMS 5 U
高品質ステレオマイクプリアンプ（ファンタム電源、MSマトリックス内蔵）
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 consumption 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 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.
A set of batteries is included with the unit.
Available separately: AC power adapter VMS 5 DC-W, a high-quality off-line switching power supply for 90 ? 264 Volt AC.
A special version (VMS 5 U lin.) without the fixed 20 Hz low-cut filter is available for measurement applications. This version is not recommended for audio applications because of the possibility of infrasonic noise problems.
