Similar to the compressor, there is no need for a Mix function here.
Gate
Noise-gates can be used in a variety of applications, both on stage and for miking instruments in the studio.
For example, they can be used to suppress feedback (e.g. 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. If set to maximum, the signal
is faded out completely.
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.

No Mix function.
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.
This effect is excellently suited for vocals (robot voice). If set to S0...7 the DSP1200 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 8-step 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.
E: carrier frequency is modulated by the signal.
R0...7: carrier frequency is modulated by a random generator.
S0...7: 1k sine generator / carrier frequency is modulated by random generator.
EDIT A: Frequency: adjusts the carrier frequency.
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 C: Modulation depth: adjusts...yes, the modulation depth.
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 high-frequency portions in the
output signal is being reduced.
+
Caution! 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)!
