[. . . ] MODULIZER PRO DSP1224P Users Manual Version 1. 0 April 2001 ® www. behringer. com ENGLISH MODULIZER PRO DSP1224P SAFETY INSTRUCTIONS CAUTION: To reduce the risk of electric shock, do not remove the cover (or back). No user serviceable parts inside; refer servicing to qualified personnel. WARNING: To reduce the risk of fire or electric shock, do not expose this appliance to rain or moisture. This symbol, wherever it appears, alerts you to the presence of uninsulated dangerous voltage inside the enclosurevoltage that may be sufficient to constitute a risk of shock. This symbol, wherever it appears, alerts you to important operating and maintenance instructions in the accompanying literature. [. . . ] from vocal mics) or to fade out vocal signals (plus background noise) during pauses. In this case, the gate must reopen very quickly, so that subdued syllables can be heard. Noise gates are often used to record or mix drum sets, so as to avoid possible crosstalk-induced phase problems. The parameters: VARIATION: Threshold: determines the threshold below which the gate cuts off the signal. EDIT A: Hold: sets how long signals below threshold can still pass the gate, to allow for a smooth control process (1-1, 000 ms). EDIT B: Range: determines the degree of attenuation when the gate is closed. EDIT C: Attack: sets how fast the gate opens when the signal has surpassed the threshold (1-100 ms). EDIT D: Release: determines how fast the gate closes after the hold time has expired (1-800 ms). The release time depends on the signal envelope, percussive sounds (short decay) need much quicker release times than, for instance, sustained keyboard pads. INTRODUCTION 15 MODULIZER PRO DSP1224P Ring Modulator This effect enables you to distort audio signals in their character. Similar to ultra-short-wave radio, the signal is multiplied with a carrier frequency, so that a frequency modulation (FM) is produced. If set to S0. . . 7 the DSP1224 acts like a sound generator because now it uses a 1k sine generator (instead of the input signal) as its modulation source. You can adjust the basic carrier frequency, LFO speed and modulation depth. The bandlimit parameter limits the frequency range of the effect signal, while random and sine generator use an additional 8step slewing rate. Additionally, you can edit the basic carrier frequency, modulation depth and LFO speed. The parameters: VARIATION: FM Modulation Mode: L: carrier frequency is modulated by LFO. S0. . . 7: 1k sine generator / carrier frequency is modulated by random generator. EDIT B: Speed: controls the LFO speed (L), the envelope follower speed (A) or the slew rate of the random generator (R and S)*). EDIT D: Bandlimit: this is a subsequent low-pass filter that is used to cut off harsh high-frequency portions. If set to 0 the filter is bypassed, and as you are increasing the value, the amount of highfrequency portions in the output signal is being reduced. If used improperly, the ring modulator effect can damage your hearing or speakers, as it produces very high-frequency signal portions (particularly if the sine generator is used which works independently of the input signal)! + Vintager Digital technology has been trying for years to produce ever more high-quality, low-noise and brilliant sounds, but most recently more and more people have been going back to the roots looking for the warmth of old analog sounds. The techno/dance community swears by vinyl anyway, and many a music lover misses the flair of good old vinyl records and tape machines.
