Stand Mounting the T89
The T89 can be mounted to any standard microphone
stand using the included mic stand holder. If you are
using a US standard 5/8-inch mic stand, remove the
Euro adapter by unscrewing it from the mic holder.
Slide the microphone into the holder from the rear to
the front with a downward motion until it snaps into
place.
Microphone Placement
To help maximize the quality of your performance,
you must pay careful attention to the placement of
your T89, and specifically, how it is positioned for
the instrument or vocalist that you’re miking. As you
become more experienced in miking techniques, you’ll
quickly realize the microphone placement is critical
to getting the sound you want while maximizing gain
before feedback. When placing the mic around any
instrument or sound source, take notice of the position
of the front of house and monitor loudspeakers.
In general, it’s good practice to set the microphone
behind the main or front of house PA speakers to
avoid feedback from those speakers. Also, position the
microphone in front of a monitor loudspeaker within a
110 degree arc as shown in the diagram below. As you’re
changing the microphone’s position, be sure to check
that the mic input is still set to a good level without
clipping, as described in the next section.
Setting Up the Signal Level
In order to get a good signal, first be sure that the
T89 is connected to a mixer or recorder input that is
microphone level. Most quality mixers, mic pre’s and
recorders provide microphone inputs with a mic trim
(“Trim” AKA Mic Gain or Level) control. The purpose
of the mic trim control is to set a good signal level and
minimize any noise associated with the mic inputs
electronics. A good mic pre will also have a Clip or Peak
LED to show you when the input is at overload; the
level which distortion begins to occur. To set a good
clean level, set the T89 up in front of the desired sound
source and slowly turn up the mic trim until you see
the Clip LED light up. Then, turn the trim control
down until the LED does not light any more. On most
microphone inputs, the best setting is when the trim
control is turned up as high as possible without lighting
the PEAK LED.
The Proximity Effect
All cardioid or uni-directional microphones exhibit
a phenomenon known as “proximity effect”. The
proximity effect is the increase in low frequency
response a microphone exhibits as it is moved closer
to the sound source. Vocalist tend to love this effect
since when they get really close to the mic they get the
“FM radio”, big bass sound. A good vocalist with good
mic technique will use the proximity effect to adjust
their tonal response in real time. The key to developing
the best mic technique is experimentation, along with
awareness of the general principle that, the closer your
T89 is to a signal source, the greater the bass response.
The proximity effect’s bass lift is caused by the amount
of pressure present at the ports that are used to
create the directional pattern. Since omnidirectional
microphones do not have ports, they do not have
proximity effect.
