The ModLink is a cable-free connection between two ModFX units that transfers digital audio and word clock. The 9-pin male connector on the left side of the unit is the ModLink IN port. The 9-pin female connector on the right side is the ModLink OUT port. By directly connecting two ModFX units via the ModLink, audio will pass from the left-most unit to the right-most unit. Inputs AC adapter Outputs What about the 1/4" jacks on the slave units? When a unit is a slave to another unit, its audio input jacks are disabled; it will get its audio input digitally from its ModLink port. The output jacks, however, are always active; so an audio output can be tapped from any linked unit, without interrupting the flow to the rest of the chain. Master First Slave Audio Flow Second Slave The audio signal flows from left to right. The Master will send its digital audio output to the First Slave, and the First Slave will, in turn, send its output to the Second Slave. 24 3 Using the Phlngr This section defines flanging, and explains the functions of the Phlngr's controls in greater detail. A little technical knowledge will help you get the most out of your gear. . . it's really pretty simple. About flanging In the 1960's, when engineers had learned how to synchronize two analog reel-to-reel tape recorders, someone discovered that if the same audio was recorded on both recorders, and you deliberately slowed one down by dragging your finger on the flange of one of the tape reels, a deep comb-filtering effect happened as the waveforms from each recorder drifted back and forth in time, trying to lock together again. This jet-airplane-like sound became famous on recordings by Jimi Hendrix, and the Small Faces. Today, instead of on tape recorders, the audio is recorded in digital memory. It gets played back a few milliseconds later, at a point that varies according to the setting of an LFO (Low Frequency Oscillator). This gives you total control of the flanging effect (and, it's a lot less hassle). Flanging is achieved by delaying one part of the signal, then varying the time delay with an LFO. The delayed signal is then mixed with the original "straight" or "dry" sound, producing a complex series of phase additions and subtractions at different frequencies. By feeding back a part of the output of the delay line to the input (REGEN), these frequency nodes become more dramatic as oscillations begin to occur at different frequencies. DRY SIGNAL Flanging vs. Phasing These two effects sometimes sound alike, but they are achieved in different ways. Phasers use shifting filters; flangers use shifting time delays. In both cases, the characteristic sound is created by peaks and dips in frequency response when the shifted signal is recombined with the unprocessed signal. Flanging has a much more complex series of additions and cancellations (peaks and troughs in the frequency response) than phasing does. It also slightly changes the pitch of the sound, which phasing doesn't. Phasing's frequency nodes are nonharmonic, and less obtrusive.
