TUBE ULTRAGAIN MIC100 User Manual (6) The GAIN control allows applying gain from +26 to +60 dB to the input signal. This control should be set fully counterclockwise when (dis)connecting a sound source to the MIC100. When all connections are made, slowly start raising gain. (7) We recommend using the LED meter to adjust gain. The LED chain displays the output signal level in dB. Please make sure that the clip LED never lights up permanently.
TUBE ULTRAGAIN MIC100 User Manual 3. Wiring Examples You’ll be surprised how flexibly you can set up your MIC100. The following chapter describes some typical wiring examples. 3.1 Enhancing vocals and instruments in live applications Here, the MIC100 is wired before the mixer’s channel input. Thus, the sound gains in warmth and transparency. Due to the integrated limiter, distortion is eliminated effectively. XLR-input Fig. 3.
TUBE ULTRAGAIN MIC100 User Manual 3.2 “Direct to Disk” application in studio or home recording environments If you are looking for a device that considerably enhances the sound of your digital workstation, this is where the MIC100 comes in. Many hard disk recorders lack a certain “liveliness”. In addition, they are often equipped with “lousy” microphone preamps. Such problems can be solved perfectly with the MIC100. XLR input ¼" TRS output Fig. 3.
TUBE ULTRAGAIN MIC100 User Manual 3.3 The MIC100 as DI-box Your MIC100 is excellently suited for this application. For example, you can connect an unbalanced acoustic guitar signal to the MIC100 to prevent hum or interference noise. What you get is a balanced, noise-free signal. ¼" TRS output ¼" TRS input XLR output Insert Microphone input Fig. 3.
