The V.A.S. Microphone Preamplifier is a single channel stand-alone device. The V.A.S. MicPre features top of the line performance, key component to achieve this performance level is our new OPA2 discrete audio operational amplifier. As all Fredenstein products, it is not a copy of an older design, but a completely new circuitry manufactured in SMT technology. Matched and integrated dual input transistors guarantee vastly improved specifications compared to older designs. The OPA2, following the tradition of well known manufactures, is socketed and can be exchanged without tools. The industry standard pin-out makes it compatible with many manufactures. Another very important sound shaping component is the American-made steel-core output transformer, which has this smooth vintage sound without being dark or just “mid-rangy” and at the same time, the V.A.S. MicPre is very quiet.
A 100 KOhms high impedance direct input is located on the front-panel, it accepts balanced and unbalanced signals, the rear microphone input is automatically disconnected when a plug is inserted in the DI connector.
The features include a maximum gain of 65 dB, Output Level Control, a 20 dB Pad, switchable polarity, selectable input impedance, switchable Low-Cut filter, and Phantom-Power support. Our new eight LED Peak-Meter with a 50 dB range gives the user a precise reading of the operating conditions. For added versatility, a hybrid headphone amplifier with separate volume control is integrated to allow precise monitoring.
The balanced input and the balanced output are available on XLR and TRS connectors. An unbalanced insert is also provided to connect effect equipment. With the optional rack mount kit, two V.A.S. devices can be mounted together to form a 19 inch 1U enclosure (table feet need to be removed). For easy touring and recording around the world, the V.A.S. MicPre has a built-in universal power supply ranging from 90Vac to 240Vac, 50 -60 Hz.
As all Fredenstein products, the V.A.S. MicPre is designed by a German-American team and manufactured in Taiwan.
