Palmer The Junction PDI-09 Manual

Specialized Guitar DI-Box
Manual
BACKGROUND
Traditionally, musical
microphone converts acoustic signals into electric signals, which in turn can be stored. Electric
instruments do not need such a conversion since they already deliver an electric signal, and Direct
Boxes (better known as DI-boxes) are used. A basic DI-Box merely adjusts the electric signal coming
out of an instrument, so that it is compatible to that of a microphone.
The greatest advantage of microphones is that they also pick up the acoustics of a room. Should the
acoustics of a room be good and suitable, you're usually better off using good microphones to
record the signal. An electric guitarist's tone is determined by both his amplifier and speakers. That's
why guitars which are recorded using a normal DI-Box does not sound like a typical guitar setup.
Using a normal EQ to try and replicate an authentic sound is generally not particularly satisfying.
Palmer speaker simulators are known to be among the best available today. The PDI-09 utilizes the
same tried and true filters that the PDI-03 and PGA-04.
RANGE OF APPLICATION
With The Junction we've developed a DI-Box that simulates the typical frequency response of a
guitar amplifier's loudspeaker. Since speaker models differ in sound, a filter has been integrated to
help you adjust the particularly critical area of higher frequencies.
The Junction PDI-09 can process line signals coming from preamplifiers and effect devices as well as
speaker levels. The Junction works on a purely passive basis and always requires preamplification--
thus it is not designed to directly connect the guitar to a mixer.
We all know that the sound quality of a guitar amplifier and its speakers are essential to your tone.
For the longest time the only way to amplify this sound was to use the classic approach in a
microphone. However, in real-life stage and studio applications, a direct signal from a guitar
amplifier can make life much easier. Live, as the acoustics change from night to night, a powerful
and crunchy sound from one night can turn into mud the next. In many performance venues, the
acoustics can be unpredictable. The audio engineer also has to constantly adjust to different setups
since a concrete stage sounds quite different from a wooden stage. The Junction, on the other hand
always produces the same results. With a direct signal both the guitarist and the engineer have a
consistently great tone to work with night after night. As an added bonus, microphone cross-talk and
feedback are completely eliminated!
Home studios benefit from the filtering circuit from the The PDI-09 when recording preamps and
pedal boards direct to the console.
The Junction is the shortest link between your pre-amp/multi-effects unit/guitar amplifier and the
mixing console. You'll be amazed to hear how good your favorite tone sounds though the PDI-09
DI-Box.
