TUBE CONDENSER MICROPHONE T-47 User Manual 2. Control elements and connections 2.1 Microphone You can tell that the T‑47 is switched on when the small window glows red. There is an XLR connector on the bottom end of the microphone. Connect it to the power supply (PSU‑T). 2.2 Power supply The included BEHRINGER PSU‑T not only provides the supply voltage for the tube preamplifier but also employs a circuit that reduces the low frequency response.
TUBE CONDENSER MICROPHONE T-47 User Manual 3. Set-up Mounting the microphone The microphone comes with an elastic shockmount. The advantage to a conventional microphone stand mount is that mechanically induced noise is virtually absorbed. To mount the microphone, attach the shockmount to the microphone stand and, from above, slide the T‑47 into the shockmount.
TUBE CONDENSER MICROPHONE T-47 User Manual Level setting / adjusting the basic sound Adjust the gain control in the microphone channel of your mixing console so that the peak LED lights up only occasionally or never at all. The EQ controls in the microphone channel should be set to mid-travel position to start with; low-cut filter and signal level attenuation should be switched off.
TUBE CONDENSER MICROPHONE T-47 User Manual 5. Audio connection To transmit a preamplified signal (OUTPUT connector on the PSU‑T), use a balanced microphone cable with the following pin assignment: pin 1 = shielding; pin 2 = +; pin 3 = -. Since your PSU‑T features gold-plated contact points, we recommend that you use only microphone cables with gold-plated connectors.
