Harman 1210KA manual Flanger, Phaser, Tremelo/Pan, Vibrato

Knob 1: Speed Controls the modulation rate of the Chorus effect. Lower settings are subtle, while higher values are much more pronounced.

Knob 2: Depth Controls the amount of pitch shifting for each voice. Lower settings provide subtle thickening and warmth to a track, while higher settings give a more pronounced, multi-voice effect.

Knob 3: Voices Controls the number of additional Chorus voices. Up to 8 voices can be added, continuously variable in 100 individual steps.

Flanger

This effect was originally created by simultaneously recording and playing back two identical programs on two tape recorders, then using hand pressure against the flange of the tape reels to slow down first one machine, then the other. The result was a series of changing phase cancellations and reinforcements, with characteristic swishing, tunneling, and fading sounds.

Knob 1: Speed Controls the modulation rate of the Flanger effect.

Knob 2: Depth Controls the intensity of the Flanger effect. Lower settings provide a slight “whooshing” sound while higher settings provide a much more dramatic “jet airplane” sound.

Knob 3: Regeneration This knob controls the amount of modulated signal being fed back into the input, creating feedback. Higher amounts add a metallic resonance to the signal.

Phaser

The Phaser automatically moves frequency notches up and down the spectrum of the signal by means of a low frequency oscillator (LFO), creating an oscillating “comb-filter” type effect. This effect is very userful on keyboards (especially pad presets) and guitars.

Knob 1: Speed Controls the modulation rate of the Phaser effect.

Knob 2: Depth Controls the intensity of the Phaser effect.

Knob 3: Regeneration This knob controls the amount of modulated signal being fed back into the input, creating feedback. Higher amounts add more resonance to the effect signal.

Tremelo/Pan

Tremolo and Panner create rhythmic changes in signal amplitude. Tremolo affects both channel’s amplitude simultaneously, while the Panner affects the amplitude of each channel in an alternating manner.

Knob 1: Speed Controls the modulation rate of the Tremolo/Panner.

Knob 2: Depth Controls the intensity of the volume amplitude change.

Knob 3: Phase Controls whether the amplitude change occurs in both channels simultaneously (Tremolo) or alternates between channels (Panner).

Vibrato

Vibrato is obtained by smoothly varying the pitch of the signal just sharp and flat of the original at a deter- mined rate. Vibrato Stereo (Wet only) Rotary Mono (Wet only) Tremolo/Pan Stereo (Wet only)

Knob 1: Speed Controls the modulation rate of Vibrato.

Knob 2: Depth Controls the maximum amount of pitch shift. Lower settings result in a mere “warble,” while higher settings produce a more exaggerated “wow” sound.

Knob 3: Phase This control sets left and right channel waveforms out of phase, resulting in a leftto- right panning motion. This effect shifts the frequency spectrum of the input signal. Altering the pitch of a sound produces a wide range effects - from subtle detunes to full interval shifts up or down a two octave range.
