2. Control Elements and Connections
2.1 Microphone
You can tell that the T‑1 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 T‑1, 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 (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. 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.
