Important Safety

Instructions

Terminals marked with this

symbol carry electrical current

of sucient magnitude to

constitute risk of electric shock. Use only

high-quality commercially-available speaker

cables with ¼" TS plugs pre-installed.

All other installation or modication should

be performed only by qualied personnel.

This symbol, wherever it

appears, alerts you to the

presence of uninsulated

dangerous voltage inside the enclosure

- voltage that may be sucient to constitute

a risk of shock.

This symbol, wherever it

appears, alerts you to important

operating and maintenance

instructions in the accompanying literature.

Please read the manual.

Always keep in mind that the

contained tube is a highly

sensitive component.

Avoid impact and other mechanical

interferences. BEHRINGER assumes no liability

for any damage caused by the user.

If possible, keep a spare tube of the same type

(12AX7) at hand.

TheT-47 is extremely sensitive to

moisture. Both the microphone

and the PSU-T power supply

should not be used near water (for example,

near a bathtub, washing machine, swimming

pool,etc.).When doing voice recordings,

always use the enclosed windscreen to

protect the capsule from moisture.

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.

After each use, wipe the

microphone down with a

soft cloth and place it back

into its protective casing (included with

the microphone).

Limited Warranty

Please register your new BEHRINGER

equipment right after your purchase by

visiting behringer.com and read the terms

and conditions of our warranty carefully.

Control elements and connections2.

Microphone2.1

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).

Power supply2.2

The included BEHRINGER PSU-T not only provides the supply voltage for the

tube preamplier 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 nd the following:

a seven-pin XLR connector to connect to the T-47 (• 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 T‑47 to the◊

power supply unit!

Set-up3.

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◊

suspending 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 lter and signal level attenuation should be switched o. 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!

Directivity4.

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.

Audio connection5.

To transmit a preamplied 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.

output

For unbalanced use, pin 1 and pin 3 have to be bridged

1 = ground/shield

2 = hot (+ve)

3 = cold (-ve)
