a bathtub, washing machine, swimming pool,etc.). When doing voice
recordings, always use the enclosed windscreen to protect the capsule
from moisture.
PSU‑T power supply:
To reduce the risk of electric shock, do not remove the top cover (or the
rear section). No user serviceable parts inside.
Do not defeat the safety purpose of the polarized or grounding-type plug.
You should only connect the T-47 to the provided power supply.
Service and care:
After each use, wipe the microphone down with a soft cloth and place it
back into its protective casing (included with the microphone).
3. Control elements and connections
3.1 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).
3.2 Power supply
The included BEHRINGER PSU-T not only provides the supply volt-
age 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.

4. 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.
Caution
+
The provided shockmount is not intended to be used for sus-
pending the T‑47!
Alternatively, you can also mount the T-47 on a microphone stand mount.
There is a screw adapter on the bottom side of the microphone.
Warming up
The T-47 can basically be used a couple of seconds after the PSU-T has
been switched on. However, the typical sound of the the T-47 only unfolds
a while after activating the power supply. We recommend allowing the
microphone to “warm up” 30 minutes before use.
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. To get the sound you want, try changing the mic position relative to
the sound source or even move the microphone around in the recording
room of your studio. Adjusting the angle at which walls face the sound
source can also be helpful. Only when the desired basic sound has been
achieved, you should start to use equalizers and signal processors, if any
at all. Remember: less is often more!
5. Directivity
Your T-47 features a capsule with a cardioid pickup pattern and is ideal
for recording individual instruments, vocals and speech. Cardioid pickup
pattern means that the sound produced by sources located in front of the
mic is strongly picked up. It is often used in recording situations, since this
directivity pattern tones down the pickup of sounds located to the back of
the microphone.
To place the microphone correctly, the BEHRINGER logo needs to face the
sound source being recorded.
6. 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.
