4TUBE CONDENSER MICROPHONE T-1 User Manual

2. Control Elements and Connections

2.1 Microphone

You can tell that the T1 is switched on when the small window glows red. It is also possible to activate an attenuation of −20 dB on the side of the T1, for example, when signal sources are very loud. There is an XLR connector on the bottom end of the microphone. Connect it to the power supply (PSUT).

2.2 Power supply

The included BEHRINGER PSUT not only provides the supply voltage for the tube preamplifier but also employs a circuit that reduces the low frequency response. This is activated on the front panel with the LOW CUT switch.

The POWER switch on the unit's rear panel turns on the power supply.
Here you also find the following:
a seven-pin XLR connector to connect to the T1 (MIC),
a three-pin XLR connector to transmit the signal (OUTPUT),
a switch to suppress signal humming noise (GND LIFT),
an IEC power receptacle
and a fuse holder.
Use the provided cable to connect the T1 to the power supply unit!
