SWITCHES AND CONTROLS

Adjust your amp regularly, as you would if you were using a speaker cab, with the ADIG-LB’s volume

controls (FILTER and FULL RANGE) shut all the way. Then adjust your amp’s volume by playing a

chord and checking the ADIG-LB’s display (the ﬁ rst two LEDs should light up with a 50w amp, at

100watts, the ﬁ rst three LEDs may light). Now you can adjust the output to your connected equip-

ment using the FILTER VOLUME or FULL RANGE VOLUME controls. If you want to use your amps

natural overdrive, increase the volume, compensating using the ADIG-LB’s controls accordingly.

Voicing: Anyone who’s compared various speakers and cabinets side-by-side can tell you how

much they inﬂ uence a guitar’s sound. When miking a guitar sound, the microphone type as well as

placement will also play a great role. The ADIG-LB offers you the same ﬂ exibility with it’s compre-

hensive tone controls. The ﬁ lter channel has two pots with which you can inﬂ uence the high as well

as the low frequency range. The HIGH control lets you adjust your sound from soft MELLOW to

aggressive BRIGHT. Of course we refrain from naming any brand names here, but the experienced

musician will be familiar with the BRITISH/CALIFORNIA categories used to describe speaker char-

acter. The LOW control will determine cabinet type, the FLAT character stands for the somewhat

thin sound typical of open 2 x 10” type cabs, while the other extreme DEEP stands for the sound

most associated with the push of a stack of 4 x 12” speaker cabs. The wide range in between will

satisfy any taste. The COLOUR switch determines the actual loudspeaker character. BROWN de-

livers a dark, slightly nasal basic quality, whereas LITE gives you a more open sound.

The effect of the COLOUR switch is also dependant on the position of the HIGH control. Those who

prefer really aggressive, distorted sounds should also mix in some of the FULL RANGE VOLUME

remembering to use the HI-CUT switch, otherwise you’ll end up with that infamous paper shredder

sound. When playing clean, however, it may be desireable to add some of the FULL RANGE signal

without any HI-CUT. The result will be a quasi-acoustic sound. Since we’ve gathered from sound

engineers that they have used the PDI-03 for other instruments beside guitar, we believe the ADIG-

LB’s facility for mixing full range and ﬁ ltered sounds will open up a whole new range of possibilities

for the creative sound engineer. That is why we refrain from giving any examples of how to recreate

this or that sound. Every guitar / amp combination has it’s own unique sound and the goal of any

self respecting musician or sound engineer should be to create unique sounds!

ATTENTION

The internal load box uses tungsten lamps. These lamps will light up during constant high power

operation. You’ll see light through the upper and lower ventilation slits, possibly the other openings

as well. Don’t panic, your machine isn’t about to burn down. However, you should, as mentioned

before ensure proper air circulation so that the heat can dissipate.

Furthermore, we’d like to remind you that ampliﬁ er output tubes will wear out sooner, the more they

have to deliver high power. Should you be running your amp at full levels to achieve the sound you

want, anticipate having to change tubes accordingly.
